The Viper turbojet engine was developed and produced by Armstrong Siddeley and then by its successor companies Bristol Siddeley and Rolls-Royce Limited. First run in April 1951 it entered service in 1953 and remained in use with the Royal Air Force, powering its Dominie T1 navigation training aircraft until January 2011. The design originally featured a seven-stage compressor based on their Adder engine — the Viper is in effect a large-scale Adder. The Viper was developed as an expendable engine for powering production versions of the Jindivik target drone, but the limited-life materials and total-loss oil systems were replaced with standard systems for use in manned aircraft. Because it was initially developed as an expendable engine, the Viper was subject to many recurring maintenance issues. This led to the development of the first Power by the Hour program in which operators would pay a fixed hourly rate to Bristol Siddeley for the continual maintenance of the engines. A production Armstrong Siddeley Viper ASV.5 turbojet, of the type specified for the Percival P.84 trainer, was to undergo high-altitude trials mounted on the tip of one wing of Armstrong Siddeley’s Sapphire – Canberra WD933 in 1954. The other wing-tip can either carry a similar turbo-jet or, as in the case of the Canberra, a counterbalancing weight. The Canberra should be able to test the Viper at altitudes up to about 50,000 ft.

The Argus As 014 (also known as the 109-014 by the RLM) was a pulse jet engine used on the German V-1 flying bomb of World War II, and the first model of pulsejet engine placed in mass production.
The origins of the Argus As 014 lie in 1928, when Munich inventor Paul Schmidt began work on a new design of pulse jet engine. Schmidt received a patent on his design in 1931 and received support from the German Air Ministry in 1933. In 1934, along with Professor Georg Madelung, Schmidt proposed a “flying bomb” to be powered by his pulse jet to the Ministry and received a development contract the following year. In 1938 he demonstrated a pulse jet–powered pilotless bomber, but the project was shelved by the Air Ministry as the prototype lacked range and accuracy and was expensive to construct. That same year, however, the Argus Company began work on a flying bomb using Schmidt’s engine (first running in 1941). Schmidt later joined Argus in 1940.
A model of simplicity and low cost, the engine was made from a sheet of mild steel rolled into a tube. At the front of the engine there was a spring flap-valve grid (shutters), a fuel inlet valve and an igniter. It could run on any grade of petroleum fuel and its shutter system was not expected to last longer than one flight, as it had an operational life of approximately one hour. The engine was a resonant jet which, contrary to popular legend, could operate while the V-1 was stationary on its launch ramp.
Ignition was accomplished by an automotive-type spark plug located about 2.5 ft (0.76 m) behind the shutter system, electricity to the plug being supplied from a portable starting unit. Three air nozzles in the front of the pulse jet were connected to an external high pressure air source which was used to start the engine. Acetylene was used for starting, and very often a panel of wood or similar was held across the end of the tailpipe to prevent the fuel from diffusing and escaping before ignition was complete.
Once the engine had been started and the temperature rose to the minimum operating level, the external air hose and connectors were removed and the resonant design of the tailpipe kept the pulse jet firing. Each cycle or pulse of the engine began with the shutters open; fuel was injected behind them and ignited, and the resulting expansion of gases forced the shutters closed. As the pressure in the engine dropped following combustion, the shutters reopened and the cycle was repeated, roughly 45 to 55 times per second. The electrical ignition system was used only to start the engine – a V-1 carried no coils or magnetos to power the spark plug once launched.
Since the engine was rather simple, low-grade gasoline could be used and a good amount of thrust — 2.7 kN (660 lb) — was produced, but it was inefficient, limiting the range of the V-1 to 150–250 miles. The resonant frequency of this combustion process was around 45 Hz, giving the V-1 its nicknames “buzz bomb” or “doodlebug”, because of the sputtering sound it emitted. The prototype engine was tested while slung below a Gotha Go 145 Luftwaffe training biplane in April 1941 and the first prototype V-1 flew on December 24 of 1942. The As 014, as well as the higher thrust As 044 pulsejet engine, was also under consideration as a power source for various last-ditch German fighters in the closing days of World War II. Production totaled 31,100 units.

License manufacture of the As 014 was carried out in Japan in the latter stages of World War II, as the Ka10, and as the American-made reverse-engineered Ford PJ31 in the United States, for powering the Republic-Ford JB-2 Loon cruise missile and the experimental USAAF-developed JB-4 television-guided bomb.
After the Second World War the As 014 was reverse-engineered / copied by Soviet Union as the Chelomey D-3 on the 10Kh (Fieseler Fi 103 look-alike).
The Planes of Fame Aeronautical Museum in Chino, California, houses what is believed to be the only operational As 014 in the world. It was restored into full operational status sometime in 2005 and retains the original valve system. The engine was run on a trailer during the annual 2009 Planes of Fame air show, the engine was used to push the trailer and the truck towing it at a speed of around 30 mph.

Argus Motoren was a German manufacturing firm known for their series of small inverted-V engines and the V-1 (flying bomb) pulse jet engine.
Started in Berlin in 1906 as a subsidiary of Henri Jeannin’s automobile business, Argus Motoren company spun off entirely in November 1906. Their early products were car and boat engines, but later that year they were contracted to produce engines for the French airship, Ville de Paris, supplying them with a converted boat motor. They turned increasingly to the aviation market, and were widely used by 1910, receiving an order from Sikorsky for one of his large airplanes under construction in Russia. During World War I Argus produced engines for the German army and air corps.
After WWI the company manufactured automobile engines and acquired a majority interest in Horch Automobile in 1919. In 1926 they resumed aircraft engine design, producing a series of inverted inline and V engines. Although all were at the “low-power” end of the market by the start of World War II, they saw extensive use in training aircraft and other utility roles. Most famous of these designs are the Argus As 10, used in the Fieseler Fi 156 Storch, in the Arado Ar 66 and in the Focke-Wulf Fw 56 Stösser; and the Argus As 410, used on many German trainers, including the Arado Ar 96.
The Berlin-Reinickendorf subcamp of Sachsenhausen concentration camp provided labor for the Argus-Werke.
Development of the Ar 234 began in 1940 at Arado’s Brandenburg plant. The German Aviation Ministry issued an order to Dr. Walter Blume, technical director of the state-owned Arado concern, to design and build a reconnaissance aircraft propelled by the turbojet engines then under development by BMW and Junkers. Rüdiger Kosin led the design team. Initially designated the E 370, Kosin created a high-wing monoplane with two turbojet engines mounted in nacelles under the wings. The rear fuselage contained two downward-looking reconnaissance cameras. The Luftwaffe specification called for the new aircraft to have a range of 1,340 miles. To house sufficient fuel in the fuselage to meet this difficult requirement, Blume had to dispense with a conventional undercarriage. The aircraft would take off from a wheeled trolley, which would be released as soon as it got airborne. The landing would be made on three retractable skids, one under the fuselage and one under each engine.
The calculated performance figures for the E 370 were a maximum speed of 485 mph at 20,000ft, a maximum operating altitude of more than 35,750ft, and a maximum range, excluding reserves, of 1,250 miles. The range was down on the stated requirement, but the Luftwaffe Technical Office approved the design and ordered the construction of two prototypes. At that point the aircraft received its official designation: Arado Ar 234. By the end of 1941 the two Ar 234 prototypes were almost complete, except for their engines. The fuselage of the Ar 234 was a circular section, semi monocoque structure with flush riveted stressed skin with a single seat cockpit in the extreme nose. The centre section, in the region of the wing and landing gear attachments, was of reinforced box girder construction. The radio equipment and tail braking parachute were stowed in the rear fuselage.
Ar234V6
This all metal cantilever monoplane’s wings were made in one piece, each a two spar structure with a flush ¬riveted stressed skin covering. The Frise ailerons had mass balanced geared tabs on their inner ends and hydraulically operated flaps were mounted inboard and outboard of the jet engines. Outboard of the jet engines were three inset lugs for the attachment of Walter 109-500 liquid fuelled rocket booster pods to assist take off. Each pod developed 1,100 lb thrust for 30sec. When the fuel was exhausted the pods parachuted to earth for reuse. The metal fin had a detachable wooden leading edge, behind which was a radio aerial. The all metal rudder had tabs along its entire trailing edge, the upper tab being geared and the lower controlled from the cockpit. The cantilever tailplane was an all metal stressed skin structure, pivoted on self aligning bearings at the leading edge. Incidence of the entire surface could be varied by a screwjack controlled by a lever in the cockpit. The narrow chord metal elevators had no trim tabs, and a single mass balance weight in the fuselage served for both the elevators and rudder. The fuel capacity was 836 Imp.gal, contained in the two fuselage tanks, one aft of the cockpit and one aft of the wing attachment fittings. There was provision to carry one 66 Imp.gal drop tank under each engine. Some aircraft were fitted with two 20mm MG 151/20 cannon in a fixed rearward firing mounting. Sighting was by means of a PV1 B periscopic gunsight, when turned to look rearwards. The gunsight graticule was reversed and inverted, so the pilot saw the target aircraft back to-front and upside down, and would then fly the Arado to place the sight on the target as if the aircraft he was engaging was in front of him. There is little evidence that the system was used successfully in action. A standard load for operations would be 1,100 lb, comprising either a high ¬explosive bomb or a cluster bomb unit carried beneath the fuselage. Although Arado completed the Ar 234 V1 airframe in late 1942, the Junkers company encountered severe problems in trying to get its new turbojet engine to run controllably and with a reasonable running life. Not until February 1943 did Arado receive its first pair of 004 engines, and these were not flight ¬cleared. They were installed in the Arado 234V1 first prototype, which then underwent static ground running and taxying trials. In the late spring of 1943 two flight cleared Jumo 004s finally become available. Even before it made its maiden flight, the aircraft was being considered for the bomber role. The subject arose at a conference at the Air Ministry in Berlin on July 1943.
Ar 234B
The Ar 234 V1 did not fly until July 30, 1943, from Rheine Airfield near Munster, with Flugkapitan Selle at the controls. There was a problem with the take off trolley. As briefed, Selle released the trolley when the aircraft reached 200ft. It fell away cleanly, but the retarding parachutes failed to deploy fully and the trolley was wrecked on hitting the ground. The company rushed a replacement trolley to Rheine for the second flight, but that was also destroyed after the parachutes again failed to open properly. After these mishaps it was decided to release the trolley when the aircraft reached flying speed, and thereafter it seldom left the ground. Further prototypes followed including the Ar 234 V6 and Ar 234 V8 which were powered by four 800 kg (1,764 1b) thrust BMW 003A-1 turbojets. The test programme gradually gained momentum, although there was a setback on October 2 when Selle was killed when the second prototype crashed during a test flight. By the end of September 1943 three further Ar 234 prototypes had flown, and a bomber version was under active consideration. The Air Ministry directed Arado to redesign the landing gear and give the jet a bombing capability and ordered two prototypes of a new version, the Ar 234B, fitted with a conventional tricycle undercarriage retracting into the fuselage. Kosin and his team enlarged the fuselage slightly to accommodate a conventional tricycle landing gear and added a semi-recessed bomb bay under the fuselage. To allow the pilot to act as a bombardier, Kosin mounted a Lotfe 7K bombsight in the fuselage floor ahead of the control column, which the pilot swung out of his way to use the sight. A Patin PDS autopilot guided the aircraft during the bombing run. The pilot-bombardier used another periscope sight during shallow-angle, glide bombing. The first prototype for the revised design, designated Ar 234 V9, flew on March 12, 1944.
The Ar 234 B had two fuel tanks mounted in the fuselage. The forward tank held 1800 lt / 396 Imp.Gal and the rear tank held 2000 lt / 440 Imp.Gal.
Refuelling Ar 234B at Rheine autumn 1944.
Four further trolley mounted aircraft flew during December 1943 and the early months of 1944: the 5th and 7th prototypes, similar to the earlier machines; the 6th prototype, with four 1,760 lb thrust BMW 003 turbojets in separate pods under the wing; and the 8th prototype with four BMW 003s paired in wing pods. To enable the aircraft to take off fully loaded from short runways when there was little or no wind, the third prototype and subsequent twin-engined aircraft had provision for the installation of a Walter 109 500 liquid fuelled rocket booster pod under each outer wing section. Weighing 616 lb apiece, the booster pods developed 1,100 lb of thrust and carried sufficient hydrogen peroxide and sodium permanganate for about 30sec running. A system of inter-connected electrical pressure switches ensured that if one pod failed to deliver thrust, that on the fuselage or on racks mounted beneath the engine nacelles.
Ar234C
The Ar 234B 1 was an unarmed reconnaiss¬ance aircraft which first served with 1 Versuchsverband OberbefehIshaber der Luftwaffe late in 1944, and soon after with Sonderkorrimando Hecht and Sperling. These units were re¬placed in 1945 by 1 (F) 33, 1 (F) 100 and 1 (F) 123, and many reconnaissance sorties were flown over the UK. The bomber version, designated Ar 234 B-0, became the first subtype built in quantity. The Air Ministry ordered 200 Ar 234 Bs and Arado built them at a new Luftwaffe airfield factory at Alt Lönnewitz in Saxony. The factory finished and delivered all 200 airplanes by the end of December 1944 but managed to roll out another 20 by war’s end. The initial order had called for two versions of the Ar 234 B: the B-1 reconnaissance aircraft and the B-2 bomber but Arado built only the B-2 version. The company converted B-2 airframes into reconnaissance aircraft. The bomber version was the Ar 234B 2, which could carry a bombload of 2000 kg (4,409 lb), and other variants included the Ar 234B 2/b reconnaiss¬ance aircraft the Ar 234B 2/1 path¬finder and Ar 234B 2/r long range bomber. Ar 234B 2 bombers joined KG 76 in January 1945 and carried out a number of raids before the end of the war. The Ar 234B’s undercarriage was of retractable tricycle type. The nose¬wheel retracted into a compartment aft of the cockpit, and was fitted with a spring and cam centralising and anti shimmy device. The main wheels retracted forward and inwards into the fuselage, and were of unusually narrow track.
The bomber version had an effective operating radius of action, carrying a 1,100 lb bomb one way and allowing reasonable fuel reserves, of about 300 miles at high altitude, or about 120 miles if the aircraft remained at low altitude. In the reconnaissance role at high altitude with two 66gal drop tanks, the aircraft had a radius of action of about 450 miles. Three modes of bombing attack were possible with the Ar 234B. The shallow dive attack, the horizontal attack from low altitude and the horizontal attack from high altitude. The shallow dive attack was the most used method, and typically involved a nose down throttled back descent from about 16,250ft to 4,500ft, during which the pilot sighted his bombs using the periscopic sight protruding from the top of his cabin.
The low altitude horizontal attack was employed only when poor visibility or low cloud at the target precluded any other method. The pilot simply ran low over his target and released the bombs by eye.
The high altitude horizontal attack used normal map ¬reading or radio navigational methods to an initial point about 18 miles from the target. He then engaged the Patin three axis autopilot and swung his control column out of the way to his right. This done, he loosened his shoulder straps and leaned forward to the bomb aiming position, over the eyepiece of the Lotfe bombsight. The bombsight’s controls were connected to the aircraft’s automatic pilot via a simple form of computer. The pilot adjusted the bombsight controls to hold the graticule over the target; the bombsight then fed the appropriate signals via the computer to the autopilot and thus “flew” the aircraft through its bombing run. When the aircraft reached the bomb release position, the system released the bombs automatically. The pilot then straightened up in his seat, tightened his shoulder straps, retrieved the control column, switched oft the autopilot and turned the aircraft around for home.
An innovation introduced with the Ar 234B was the use of a tail brake parachute to shorten the landing run. It was the first combat aircraft to have this fitted as standard.
Plans called for more advanced versions of the Arado jet, including the Ar 234 C powered by four 1,760 lb thrust BMW 003 A-1 engines and fitted with a pressurized cockpit. Subvariants of the “C” model included the C-3 multi-role aircraft and the C-3N two-seat nightfighter. However, only 14 Ar 234 Cs left the Arado factory before Soviet forces overran the area. The four-engine Ar 234 was, however, the fastest jet aircraft of World War II. With the extra engine thrust this version could take off fully laden from shorter airfields without the use of booster rockets. Peter Kappus, a test pilot with BMW who flew the Ar 234C, later recalled: “The four engined Ar 234C had a very high performance in the take off and the climb. But it could not be flown at full power horizontally, because at the very high speeds reached it structural flutter problems.”
Prototypes for the more advanced Ar 234 D reconnaissance aircraft and bomber with provision for a second crewman were under construction but not completed at war’s end.
Early in 1945 a few Ar 234Bs were modified for use as night-fighters with Kornmando Bonow. These aircraft carried the FuG 218 Neptun radar, with nose-mounted aerials. The radar operator sat in an improvised position inside the rear fuselage, aft of the wing. For this role the Ar 234B was armed with two 20mm MG 151 cannon in a pack mounted under the fuselage. One idea tried out as a means of increasing the radius of action of the Ar 234 bomber was to tow a V1 flying bomb, with the warhead, engine and tailplane removed and a wheeled undercarriage fitted, to carry extra fuel. The idea was not a success and the scheme was never tried in action. During March 1945 Soviet troops advanced into eastern Germany, and the Arado plant at Alt Loennewitz came under threat. To prevent it failing into enemy hands, German Army engineers destroyed the factory with explosives. This brought production to a precipitate halt, after just 210 Ar 234Bs and 14 Ar 234Cs had been delivered to the Luftwaffe. The Arados reached their high point with their prolonged attacks on the big Remagen bridge across the Rhine, and their 1 000 kg (2,205 1b) bombs dropped from low level in shallow dive attacks finally brought the bridge down after 10 days on 17 March 1945. But by then the Allied armies were well into Germany. About 60 of the 210 Arados delivered were captured in flying condition, and most Allied countries had a whole squadron of them in mid 1945. Apart from the critical nature of some take offs, the Ar 234 was found to be a fine aircraft, with no severe Mach trouble up to 0.8 and a range in clean condition of well over 1610 km (1,000 miles).
Characteristics The take off run was long, but single engine safety speed was 140 mph (225km/h) when the aircraft would swing and bank, although not violently, and provided corrective action was taken within 2sec it could be held straight without loss of height. Flaps were raised after reaching 155 m.p.h. (250km/h) and then speed for the initial climb built up to 250 m.p.h. (400km/h). This was reduced to 235 m.p.h. (380km/h) after passing through 26,250ft (8,000m) altitude to give optimum rate of climb. The maximum initial climb rate was 2,500ft/min (12.7m/sec) but had reduced to 1,800ft/min (9.14m/sec) by 10,000ft (3,000m) and to 1,000ft/min (5.08m/sec) by 20,000ft (6,000m). These figures were certainly good for a 1945 vintage reconnaissance bomber but the top speed of 475 mph (765km/h) was what made Blitz so appropriate a name for the Ar 234B. The Blitz handled beautifully at high altitude, its stability about all axes being positive and the harmony of control being good. These characteristics, allied to the superlative view that it offered its pilot, made the Ar 234B a first class platform for photography or bombing. Quality control was suffering adversely in the chaotic conditions prevailing in the German aircraft industry as a result of the heavy Allied bombing attacks. On the Blitz the extremely sharp nosed Frise ailerons were very sensitive to rigging errors and could misbehave violently at speeds above 370 m.p.h. (600km/h), a common fault being rapid oscillation of the ailerons The Blitz suffered from directional snaking, and as often as not this undesirable characteristic was aggravated by poor manufacturing standards on the rudder which sometimes came out fatter or thinner than the fin profile. The Arado company failed to tackle this problem, merely rectifying the fault by off-setting the rudder hinge to one side, or by rigging the balance and trim tabs out in opposite directions. German test pilots did not investigate the high Mach characteristics of the Ar 234B, although normal production testing involved a dive from 10,000ft (3,000m) up to a true speed of 530 m.p.h. (850km/h) low altitude work that did not involve compressibility effects. The transonic region was, therefore, virtually fresh ground for the Royal Aircraft Establishment. In a series of dives from an altitude of 30,000ft (9,100m). The Blitz accelerated less than expected from maximum cruising speed and so a dive of some 30 degrees was needed to achieve the desired entry into the compressibility region before too much altitude was lost. This also entailed using nose down trim, as otherwise the push force to hold the dive angle became too high. At M0.76 nose heaviness set in and the elevator began to feel sloppy. These effects were accentuated until at M0.82 full backward pull on the stick was required to hold the dive angle constant and to allow the loss of altitude to have its density effect on reducing true airspeed until recovery could be effected. For its role as a reconnaissance bomber, therefore, the Ar 234B had a tactical Mach number of 0.75 while its top speed at around 30,000ft (9,145m) was about M0.72. The low speed end of the performance envelope displayed extremely docile characteristics at the stall, this being a straightforward and gentle nose drop. Stalling speed in landing condition was 112 m.p.h. (180km/h). Landing was very easy since the view from the cockpit was superb. The maximum speed for lowering the undercarriage was 250 m.p.h. (400km/h) and then flaps to 25O at 200 m.p.h. (320km/h). It was best to apply full 45O flap after turning on to the final approach at about 175 m.p.h. (280km/h), reducing speed to 130 mph (210km/h), and, when sure of making the airfield, easing back the throttles to idling at 4,000 rpm., crossing the boundary at 125 mph (200km/h). The landing run was lengthy as the rather ineffective brakes faded badly, having to be held on continuously throughout the ground run. All versions of the Blitz had a braking ‘chute fitted which halved the landing run.
Operations The 5th and 7th prototype Ar 234s each carried a pair of Rb 50/30 aerial cameras mounted nearly vertically in the rear fuselage. Fitted with 50cm long focus lenses, the cameras were splayed outwards away from each other at 120 to the vertical, perpendicular to the line of flight. From 32,500ft this split pair camera arrangement took in a swathe of ground just over 6 miles wide along the aircraft’s track. The 5th and 7th prototypes were delivered to the Versuchsverband der Oberkommando der Luftwaffe (Luftwaffe High Command Trials Detachment) based at Oranienburg, a special reconnaissance unit under the direct control of the Luftwaffe High Command. Oberieutnant Horst Goetz took command of the Arado 234 detachment, and he and another pilot, Leutnant Erich Sommer, began learning to fly the new aircraft. In mid July 1944 Goetz received orders to move the Ar 234 detachment to Juvincourt, near Reims in France, to begin reconnaissance operations over the Western Front. From the start there were problems. On July 17 the two Arados took off from Oranienburg, but soon after getting airborne Goetz suffered an engine failure and had to turn back. Sommer continued on to Juvincourt, and landed without incident. After landing, his aircraft was hoisted on to a low loading trailer and towed into a hangar. Then the world’s most advanced reconnaissance aircraft had to remain, unusable, until its tailor¬-made take off trolley arrived from Oranienburg by rail (since there were minor differences between the two hand built prototypes, their take off trolleys were not interchangeable). By that time the Allied bombing campaign had reduced the French rail system to a state of near chaos. Despite the high priority accorded the move, more than two weeks elapsed before the trucks carrying the take¬off trollev reached Juvincourt. At last, on the morning of August 2, everything was ready for Sommer to set out on the world’s first jet reconnaissance mission. It took Sommer about 20min to climb to 34,000ft, by which time the Arado was almost over the battle area. High over the Cherbourg Peninsula he turned the aircraft on to an easterly heading, eased down the nose and descended to build up his speed to about 462 mph. He levelled off and concen¬trated on flying exactly straight and level for his first photographic run. The doors protecting the camera lenses were open, and Sommer flicked the switch to activate the two cameras. The automatic mechanism on each camera took one picture every 11 sec. If any Allied fighter attempted to catch the high flying Arado, Sommer never noticed it. That first photographic run, taking in the coastal strip, lasted about 10 min. Then Sommer turned through a semi circle and levelled out, heading due west for a second run parallel to the first and about 6 miles inland. The second run completed, he turned on to an easterly heading and flew a third run 6 miles further inland and parallel to the previous two. Near the end of the third run the counters on the camera panel clicked to zero. In a flight lasting less than 90min he had photographed almost the entire Allied lodgement area in Normandy. The 380 photographs he had taken caused a considerable stir. During the three weeks that followed the two aircraft flew 13 further missions. On August 28 American tanks neared Reims, and Goetz received orders to move the two Ar 234s from Juvincourt to Chibvres in Belgium. As Goetz prepared to land at Chievres, the ground defences, long conditioned to treat any approaching aircraft as hostile, opened fire at him. An accurate shell struck the Ar 234 just beneath the cockpit, knocking out the aircraft’s electrical and hydraulic systems. Goetz broke off his approach and found that his flaps and landing skids would not extend. The aircraft was still flyable, however, so he flew it back to Oranienburg, where there were proper repair facilities. There Goetz made a skilful flapless belly landing, touching down at about 190 m.p.h. The valuable aircraft came to a halt having suffered remarkably little damage, and Goetz climbed out of the cockpit. Then the Arado received its coup de grace. A young fighter pilot taking off from the airfield, not expecting such an obstacle to be in his path, ran straight into the rear of the Arado and the propeller of his aircraft severed the complete tail unit. Goetz emerged with cuts from stones and flying glass, and was unable to see clearly for a couple of weeks. The Ar 234 was wrecked. Sommer landed his Ar 234 at Chievres without difficulty, then as Allied tanks approached the area he had to move to Volkel in Holland a few days later. Sommer was there on September 3, when over 100 RAF Lancasters carried out a heavy daylight attack on the airfield. Although the landing ground and camp areas were pockmarked with craters, Sommer’s Ar 234 sat undamaged in its hangar The airfield was judged unusable for normal operations, so on the following day, September 4, Sommer made a trolley take off from one of the taxy tracks after some of the craters had been filled in. He landed the Ar 234 at Rheine, near Osnabruck, the new base for jet reconnaissance operations. The withdrawal of the unit to Germany coincided with an end to missions using the take off trolley, for in September the Ar 234B with a normal undercarriage became available. The slightly wider fuselage necessary to accommodate the undercarriage reduced the maximum speed by about 20 mph, but still the aircraft was fast enough to avoid fighter interception. There was also a reduction in the radius of action, but there was provision to carry a 66gal drop tank under each engine for the longer missions. In return for these limitations the Ar 234B was a considerably more versatile machine able to operate from airfields without specialist ground equipment. At Rheine, Goetz’s unit, now designated Kommando Sperfing (Sparrow), gradually built up to nine Ar 234Bs and flew almost daily reconnaissance missions. Standing patrols over the airfield by Allied fighters posed a continual problem, however. The only time an airborne Ar 234 was vulnerable to fighter attack was when it was flying slowly immediately after take off, or before landing. On January 10, 1945, the Luftwaffe Quartermaster General’s list recorded only five reconnaissance Ar 234Bs in service, four with Kornmando Sperling and one with Kornmando Hecht. From September 1944 until the end of the war the reconnaissance Ar 234Bs operated regularly, photographing Allied positions with minimal interference. Early in 1945 Goetz’s Kornmando Sperling had been expanded into a Staffel, and it was redesignated as 1st Staffel of Fernaufklarungsgruppe (FAGr long range reconnaissance group) 123. Two other reconnaissance Staffeln also re equipped with the Ar 23413, one being attached to FAGr 100 and one to FAGr 33. In addition, Erich Sommer had formed his own unit, Kornmando Sommer, equipped with three Ar 234Bs and operating on the Italian front. Not until February 11, 1945, after more than six months, was a reconnaissance Ar 234 lost to an Allied fighter. On that day Scin Ldr David Fairbanks was leading an armed reconnaissance by eight Hawker Tempests of 274 Sqn RAF when he spotted a lone jet aircraft which he took to be an Me 262. After a lengthy chase he caught up with the machine as it slowed to land at Rheine, and shot it down. It was an Ar 234B of Goet’s unit, piloted by Hptm Hans Felden, returning from a photographic mission over Hull. Felden was killed. Kornmando Sommer, based at Udine in Italy, suffered its only pilot loss on April 11. Leutnant Gunther Gniesmer was near Bologna when he had the bad luck to run into a formation of bombers escorted by P 51s of the 52nd FG. Lieutenants Hall and Cooper succeeded in reaching firing positions, and shot him down. Gniesmer baled out, but as he fell clear he struck the tailplane and died in hospital a few days later. The Ar 234 was consistently successful in penetrating deep into enemy territory and bringing back vital pictures. These flights often went undetected by the enemy, and if they were detected the Arados were difficult to shoot down. During the early morning darkness of January 1, 1945, Lukesch led four Ar 234Bs for the world’s first night jet bombing mission. The aircraft took off from Munster Handorf and flew a circular route which took them over Brussels and Liege, dropping bombs on each. The bombing was intended to deceive the enemy rather than cause damage, however. The aim of the mission was to report on the weather over Belgium and Holland in preparation for Operation Boden¬platte (Baseplate), the massed Luftwaffe attack on Allied airfields scheduled to open soon after dawn. By the end of 1944 the Luftwaffe had accepted 148 Ar 234Bs. Yet on January 10, 1945, the Quartermaster General’s list recorded only 12 Ar 234B bombers in front line service, of which 11 were serviceable. All served with 9th Staffel of KG76. By then the remainder of the Geschwader was in the process of re equipping with the type, but about half of the Ar 234s built were sitting in aircraft parks. The crescendo of Allied air attacks on the German transport system greatly hindered the formation of operational units equipped with the Ar 234B, as with other new types. On April 10, 1945, the last date for which figures exist, the Quartermaster General’s report listed a mere dozen Ar 234Bs in service with operational bomber units, of which four were serviceable. The largest attack by Arados on a single day, on February 27, 1945, involved only 37 Arado sorties. The total bomb load carried, 18.25 tons, caused only minor inconvenience to the Allied troops dispersed over a large area.
On 10 April 1945, an Arado 234B-1 reconnaissance aircraft took off from Sula Airfield in Stavanger, Norway. The plane took photographs of Scotland and landed back at Sala 2 hr 30 min later. The Luftwaffe had just ended its last mission over Britain.
The National Air and Space Museum’s Blitz, an Arado Ar 234 B-2 bomber carrying Werk Nummer (manufacturer’s serial number) 140312, was one of nine Ar 234s surrendered to British forces at Sola airfield near Stavanger, Norway. It is the sole surviving example of an Ar 234. The aircraft had been on strength with 9./KG 76 (Ninth Squadron/ bomber Wing 76) during the final weeks of the war, having served earlier with the unit’s eighth squadron. It and three other Ar 234s were collected by the famous “Watson’s Whizzers” group of the USAAF (United States Army Air Forces) for shipment to the United States. After flying from Sola to Cherbourg, France on June 24, 1945, the four Ar 234s joined thirty-four other advanced German aircraft aboard the British aircraft carrier HMS Reaper for shipment to the United States. The Reaper departed from Cherbourg on July 20, arriving at Newark, New Jersey eight days later. U. S. Army Air Forces personnel reassembled and flew two Ar 234s, including 140312, to Freeman Field, Indiana, for testing and evaluation. The USAAF assigned the foreign equipment number FE-1010 to this Ar 234 for inventory and tracking purpose. The only surviving example was in 2004 on display at the Steven F Udvar Hazy Center at Dulles Airport in Washington DC.

The An-225 Mriya (dream) stemmed from the need to transport large items for the Soviet space programme. In mid-1985 Antonov began the design and the An-124 provided the basis for the new aircraft, Antonov using many of the same components to keep cost and development effort down. Standard An-124, wings are grafted on to a new centre section, thereby increasing the span while keeping the engine installations the same. An additional pair of D-36T turbofans is fitted to the new centre section.
The cabin retains the same cross-sectional dimensions but with increased length, and to save weight the rear loading ramp is removed, but the An-225 retains the nose visor.
To support the increased weight, seven pairs of wheels are fitted to each side as opposed to five in the An-124. Outsize loads are carried ‘piggy-back’, the load supported on two main attachments above the centre section. These supports and other smaller ones along the fuselage top are faired over when not in use. To avoid buffeting from the ‘piggyback’ load, the An-225 has twin vertical fins mounted on the end of a large tailplane.
The prototype made its first flight on 21 December 1988 from Hostomel Airport outside Kiev, Ukraine, and the first flew with Buran on 13 May 1989 from Baikonur cosmodrome. This combination appeared at the Paris air show in 1989, car¬rying the 62.1 tonne (136,684 lb) Buran on its back.
On 22 March 1989, in the course of a single 3 hr 30 minute flight from Kiev, the An-225 set 105 world and class records. With a payload of 344,576 lb / 156,300 kg, the machine took off at a weight of 1,120,370 lb / 508,200 kg. It proceeded to fly a 1243 mile / 2000 km closed circuit at an average speed of 505.24 mph / 813.09 kph and to reach a maximum altitude of 40,485 ft / 12,340 m.
Typically, the An-225 carries two pilots, two flight engineers and two navigators, the flight system incorporating fly-by-wire controls. NATO name Cossack.
The Antonov An-225 has been extensively modified since 1988 with its six engines being updated and a strengthened fuselage being among the many changes.
The first commercial flight was performed by the An-225 in May, 1990. A T-800 tractor weighing more than 100 tons was delivered from Chelyabinsk to Yakutia.
After the collapse of the USSR the only plane stopped flying in 1994 and some parts were disassembled to be used on other planes. However by the 2000s it was restored by efforts of some Ukrainian companies. The airliner was amended a bit to meet the standards of civil aviation first flying aain on the 7th of May, 2001.
Antonov planned to finish building a second An-225 if they have financial support. 70% was ready; the centre wing-section, fuselage and a wing remained since the Soviet times. If they had a customer they would finish it, requiring $150 million.

The Antonov An-178 (Ukrainian: Антонов Ан-178) is a short-range medium-airlift military transport aircraft designed by the Ukrainian Antonov company and based on the Antonov An-158 (An-148-200).
An-178 is a high-wing transport aircraft with moderately swept wing, winglets and a T-tail. The wing outer panels (including winglets), front fuselage with cockpit and nosewheel leg come from the An-158. The cargo hold is slightly enlarged, and there is an extra pair of main-wheels on each side. The airframe is made of aluminium alloys and composite materials. The fuselage is semi-monocoque with a circular cross-section. The retractable landing gear consists of two main wheel bogies and a dual nose wheel. The flight control system is dual duplex fly-by-wire system, consisting of two parts: FCS-A and FCS-B, each of which is responsible for two control channels. The flight control surfaces include ailerons near the wing tips, four control spoilers, six lift-dump/speed-brake spoilers, rudder and elevators, with an emergency mechanical cable back-up system. The powerplant consists of two Progress D-436-148FM turbofan engines, mounted on pylons under the wings and an auxiliary power unit. It can shift 18 tonnes over 1,000 km, or 10 tonnes over 4,000 km.
The aircraft was derived from the 99-seat An-158 regional airliner and was fitted with the commonized F1 fuselage nose section with the identical flight deck, wing panels, empennage and most of the onboard systems. The fuselage however was newly created with an enlarged diameter that had grown from 3.35 m to 3.9 m, which has resulted in an enlarged cargo hold – the cargo cabin cross section increased to 2.75 m by 2.75 m. Aside from the wing structure, outer panels (including winglets), front fuselage nose, cockpit and nose landing gear which come from the An-158, there is an extra pair of tandem main-wheels on each side.
The An-178 was previously known as the An-148T. The aircraft made its Western debut at the 2015 Paris Air Show.
It was announced on 5 February 2010, rolled out on 16 April 2015 and the maiden flight was on 7 May 2015.
There are reports that future production-standard aircraft will have a longer wingspan while retaining the organic wing panels of the An-158. Its maximal take-off weight would increase to an estimated 56 tons. Later production variants would need turbofan engines with a thrust of about 9,500 kgf to have the characteristics required. The planned engine may be the new-generation in-development Ivchenko-Progress AI-28 turbofan. The decision was made to fit the An-178 prototype with less powerful D-436-148FM engines in the interim. The D-436-148FM is a derivative of the production-standard D-436-148 with an upgraded fan, which boosted the takeoff thrust to 7,800 kgf and at emergency power rating to 8,580 kgf.
Powerplant: 2 × Progress D-436-148FM Turbofan, 73.55 kN (16,534 lbf) Wingspan: 30.57 m (100 ft 4 in) Length: 32.23 m (105 ft 9 in) Height: 9.57 m (31 ft 5 in) Max takeoff weight: 51,000 kg (112,436 lb) Fuel capacity: 14,650 kg (32,298 lb) Max landing weight: 47,000 kg (103,617 lb) Maximum speed: 990 km/h (620 mph, 530 kn) Cruise speed: 825 km/h (513 mph, 445 kn) Range: 4,700 km (2,900 mi, 2,500 nmi) Ferry range: 5,300 km (3,300 mi, 2,900 nmi) Service ceiling: 12,000 m (39,000 ft) Landing distance: 2,500 m (8,200 ft) Crew: 2 Capacity: 90 soldiers, 70 paratroopers, 48 on stretchers +15 seated, 8 medical modules and 12, or 16 tons of cargo, overload variant 18 tons.
The Antonov An-148 (Ukrainian: Антонов Ан-148) is a regional jet designed and built by Antonov of Ukraine.
The beginning of the An-148 project dates to the early 1990s, when work on the Antonov An-74 passenger modification started, headed by Petro Balabuev. In 2001, the project was renamed An-148. The An-74 fuselage was extended and the new aircraft’s wing design was created from scratch. The developers initially used Motor Sich D-436-148 engines.
The An-148 aircraft is a high-wing monoplane with two turbofan jet engines mounted in pods under the wing. This arrangement protects the engines and wing structure against foreign object damage. A built-in autodiagnosis system, auxiliary power unit, and the wing configuration allow the An-148 to be used at poorly equipped airfields. Flight and navigation equipment features five 15 by 20 cm (5.9 by 7.9 in) liquid crystal display panels built by Russia’s Aviapribor and a fly-by-wire system.
The main landing gear rotates into the belly of the aircraft when in flight, with partial doors covering the legs, and the sides of the tires remaining exposed. Built-in entrance stairs enable boarding and disembarking the aircraft without extra ground equipment.
The An-148-100 regional aircraft is the main model of the An-148. It seats 70 passengers at 864 mm (34.0 in) or up to 80 passengers at 762 mm (30.0 in) pitch in a one-class 2+3 seating layout. The aircraft is also configurable in a multiple-class layout which can carry fewer passengers, typically with four abreast business class.
In 2002, production of the first three prototypes was begun at AVIANT. On 17 December 2004, the first prototype completed its maiden flight. The second prototype joined the testing programme in April 2005. During the certification programme, the two prototypes performed about 600 flights in total. On 26 February 2007, the aircraft, its D-436-148 engine and the AI-450-МS auxiliary power unit were certified by the Interstate Aviation Committee of Russia and the State Aviation Administration of Ukraine.
The first prototype. It made its maiden flight on 17 December 2004.
The aircraft completed its certification programme on 26 February 2007. The An-148 has a maximum range of 2,100–4,400 km (1,100–2,400 nmi; 1,300–2,700 mi) and is able to carry 68–85 passengers, depending on the configuration.
The An-148 was manufactured by the Ukrainian Kyiv AVIANT plant (now Antonov Serial Production Plant) and Russia’s Voronezh Aircraft Production Association (VASO). On 28 June 2009, the first serially produced An-148, manufactured at VASO in Voronezh, took to the skies. Although numerous companies are involved in the project, at least 70% of the aircraft’s hardware is made by Russian manufacturers. The An-148’s list price is about $24–30 million. The main problem with the project has been increasing the aircraft’s sluggish production rate. The then-independent AVIANT plant initially failed to satisfy to growing orders, leading to VASO’s growing involvement in the aircraft’s assembly. VASO announced in June 2017 that the two final Russian-assembled An-148s would be delivered, and the project would not see further development.
In April 2005, the Ilyushin Finance Leasing Company ordered the first series of An-148 for the Krasair airline. Lease agreement calls for ten aircraft with an option for five units valued at $270 million.
The Antonov An-158 is a stretched fuselage version of the aircraft, accommodating up to 100 passengers.
An-158
The An-158 is a 1.7m stretched fuselage version for 99 passengers in a one-class standard configuration. Other changes include the installation of wingtip fences. The airplane successfully completed its first flight on 28 April 2010, with flight certification tests were planned to be completed before the end of 2010; on 3 March 2011, it was given Russian certification.
After flight and land test in night lands airports of Ecuador (Latacunga / Cotopaxi International Airport, 2806 m AMSL) and Bolivia (La Paz / El Alto International Airport, 4061 m AMSL) in November 2013 prepare documentation for obtaining correspondent supplements to the type certificate of this airplane.
On 2 June 2009, the first An-148 entered commercial service with the Ukrainian carrier Aerosvit. The first passenger flight was from Kharkiv to Kyiv; the aircraft had the civilian registration UR-NTA. By November 2009, Aerosvit was operating the An-148 on the Kyiv–Odessa and Simferopol–Lviv routes, performing two flights a day with the average flight time of 4–5 hours.
On 21 December 2009, the An-148 was put into service in Russia with Rossiya airline. The first passenger flight was FV135 from Pulkovo Airport in Saint Petersburg to Sheremetyevo International Airport in Moscow. By 20 May 2010, Rossiya’s An-148 fleet had accumulated a total of 915 flight hours and performed 710 landings. Rossiya complained that the aircraft experienced some reliability problems. There were some technical problems with the aircraft, and pilot training could not be ramped up fast enough, leading to pilot shortages. However, by 2011 the situation had improved.
On 15 February 2010, the An-148 started international flights to the European Union (Poland) with the Aerosvit airline.
The first An-158 in April 2010
On 18 April 2013, the first serial An-158 version was delivered to the Cuban flagship airline Cubana de Aviación. According to Antonov, Cubana additionally ordered two more aircraft, while other sources report this order to be for ten aircraft. On 28 April 2013, Ukraine’s Antonov aircraft maker handed over a third An-158 passenger airliner to Cuba and signed a contract for the delivery of three more.
Following a crash in February 2018, all An-148 and An-158 in Russia were grounded by the Russian Ministry of Transport. In addition, Cubana grounded its An-158 fleet as of May 2018 due to several technical issues with the aircraft. Until late 2018, the Antonov An-148 aircraft was also being produced in Russia by Voronezh Aircraft Production Association; however, due to the souring political relationship between Ukraine and Russia, production in Russia was discontinued. The last Russian-built An-148 was completed in October 2018.
In April 2016, Indian company Reliance defense limited and Antonov entered into an agreement to construct an aircraft based on An 148/ An 158 for defense and commercial purposes.
In April 2017, Cubana de Aviación suspended its flights between Havana and Guantánamo due to “technical problems” with its An-158 fleet. The route from Havana to Holguín also had problems: of 116 planned flights in the first months of 2017, 38 were cancelled and 36 suffered significant delays. Yoanka Acosta, head of Cubana’s commercial division, explained that the planes were leased from Ukraine but spare parts were sourced from Russia, so the state of conflict between the two countries had affected the supply of parts, making maintenance difficult. In late April, however, representatives from Antonov and Cubana met and signed a service agreement that extended the aircraft’s navigation directives to 3,600 flights and guaranteed the supply of spare parts, although it did not specify a date for normalization.
In March 2018 Rostransnadzor suspended all flights of An-148 in Russia after crash on 11 February 2018.
In May 2018, Cubana de Aviación grounded its An-158 fleet after it received an order from the Cuban National Aviation Authority. The official reason given by the Cuban National Aviation Authority was “multiple and repeating failures have been found in complex systems, built by mechanical, hydraulic and electrical components, as well as computer performance algorithms”, in addition to “evidence of design and manufacturing flaws, serious issues in flight control system, cracks in the structure and engine temperature increase above normal parameters”.
On 5 March 2011, an Antonov An-148 (assembled by VASO) carrying test registration 61708 crashed during a test flight in Russia’s Belgorod Oblast after an inflight breakup, killing all six crew members on board. An investigation commission found that the crew permitted the aircraft to accelerate more than 60 knots above its “Never Exceed” speed in an emergency descent, which led to the inflight breakup. Witnesses on the ground reported a wing had separated from the aircraft in flight. The aircraft was due to be delivered to Myanmar.
On 11 February 2018, an Antonov An-148 operating as Saratov Airlines Flight 703, crashed shortly after takeoff near Ramenskoye, outside of Moscow. The aircraft was carrying 65 passengers and six crew members. There were no survivors. This is the first fatal commercial accident for this aircraft type.
At least 47 were built.

The An-124 strategic airlifter, Nato code name Condor, first flew on December 26, 1982 with Vladimir Terski at the controls, and at least nine had been built by June 1987. At the time of its first flight, the An-124 was the largest aircraft in the world. The An-124 is powered by four 230kN-thrust Lotarev D-18T high-bypass turbofans, and is claimed to carry its 150-tonne maximum payload over 4,500km. Designed for simultaneous nose and tail loading, with a visor-type lifting nose and integral forward-folding ramp, the pressurised cargo hold is 36m long, 6.4m wide, and 4.4m high. A pressurised upper deck can accommodate 88 passengers. The An-124 has a six-man crew (two pilots, two engineers, a navigator and a radio operator), dual weather and ground mapping raders, quadruplex inertial navigation, and anologue fly-by-wire controls with mechanical backup operating hydraulic control servos. Two overhead travelling cranes, which have a lifting capacity of 30 tonnes, and two winches allow heavy cargo to be self-loaded without the use of special airport loading equipment. To enable the carriage of extremely heavy cargo, HeavyLift-Volga-Dnepr have developed special loading systems allowing individual items of up to 100 tonnes to be loaded. In addition, two double-deck car-racking systems have been built allowing up to 50 cars to be carried in one flight. Approximately 5,500kg of composite materials are used in doors, fairings, and panels, including 3,000kg of carbonfibre, giving a 1,800kg overall weight saving.
The second aircraft, named Ruslan, appeared at the 1985 Paris Air Salon. The aircraft entered service with Aeroflot in early 1986, and now serves principally on the Siberian run, carrying outsize items to the oil and mineral exploitation industries. In 1987 the An-124 began service with the air force. Production is reportedly eight to ten aircraft per year, and by 1989 over 25 had been completed. The An-124 was assigned the NATO reporting name ‘Condor’. The An-124-100 is a civil varient, certified in Russia. They are built one at a time and take about three and a half years to construct. Its 24-wheel undercarriage allow it to go into semi-prepared strips and the two nose-wheel units can be retracted on the ground allowing the aircraft to ‘kneel’ to assist loading. The large undercarriage system, the full-span, leading-edge slats and flaps give the An-124 very good short field performance. Full-span leading-edge slats and large flaps give the An-124 short field capability, while its 20 main wheels allow the type to use rough fields.. Civil examples were with Antonov Air Foyle, HeavyLift Volga Dnepr and the Russian-Australian joint venture, Antonov Airlines.

Flight testing of an An-74 develop¬ment of the An-72 Coaler twin-turbofan Stol transport was announced early in February 1984. The An-74 has been developed specifically for use in the Arctic and Antarctic, and may be equipped with an interchangeable landing gear, with skis available for operations from ice and snow. Principal differences apparent in the An-74 are a longer fuselage with a nose-mounted radar, and a redesigned wing. First flown in 1977, the An-72, and the related An-74, only received its airworthiness certificate when the An-74TK was certified by Aeronautical Register on 2 August 1991. The An-74 was also produced at Kharkov from December 1989.
Antonov An-74TK-100C RA-74006
Production of An-74 also started by Polyot Industrial Association at Omsk, Russia, in 1993 (assisted by Progress at Arsenyev); first Polyot aircraft (RA-74050) was flown 25 December 1993.
An An-72P maritime patrol version was demonstrated 1992 and development of the An-74-200 and An-74TK-200 by Antonov started 1995. The An-74TK-300 is basically an An-74TK-200 with underslung engines. The An-88 is a tactical battlefield surveillance aircraft based on An-72 (also known as An-72R).
An-74 Coaler Engine: 2 x Lotarev D-36 turbofan. Installed thrust: 127.4 kN. Span: 31.9 m. Length: 28.7 m. MTOW: 34,500 kg. Payload: 10,000 kg. Cruise speed: 550 kph. Ceiling: 10,500 m. T/O run: 470 m. Range/payload: 3300 km with 5000 kg.
Originating as private venture military transport based on stillborn An-60 64-73 seat civil airliner designed to meet 1967 specification, the revised design, following issue of military requirement in 1968, included relocation of engines above wings.
Two static test airframes, and two prototype An-72 were built at Kiev. The first (SSSR-197744) flew on 31 August 1977. Intended to replace the turboprop powered An 26 in Aeroflot service, its high lift devices and multi wheel landing gear make it suitable for operation from unprepared airfields with snow or ice covering and accommodate about 52 passengers. Overwing engines exhaust over the wing and trailing edge devices, to increase lift at low airspeeds. The NATO named Coaler is designed for rough-field operations and has a rear cargo door/ramp. A production order was placed in December 1980 for an improved An-72A version, when manufacture was transferred to Kharkov, Ukraine, where first production An-72 flew 22 December 1985. The An-72, and the related An-74, only received its airworthiness certificate in 1991. By mid-1992, about 50 were in industrial service, although none with Aeroflot. The An-72 platform went on to spawn other variants that included maritime surveillance An-72P model, the An-71 “Madcap” AEW model and the An-74 “improved Coaler” upgraded engines and a conventional engine mounting. The An-72P armed surveillance and maritime patrol aircraft was developed in conjunction with Israeli Aircraft Industries and featured revised cockpit glass design, specialized Elta radar, electronic warfare systems and long range day/night observation equipment and systems.
The An-74 is a civil development of the An-72.
