Reid & Sigrist R.S.1 Snargasher

Reid & Sigrist Ltd built a twin-engined advanced trainer popularly known as the Snargasher, of which only a prototype (G-AEOD) was built.

A three seat trainer built at Desford shortly before the Second World War, power was by two de Havilland Gipsy Six engines. The aircraft’s first public appearance was at the Royal Aeronautical Society garden party at Heathrow in May 1939.

During the war the Snargasher flew as the maker’s communication aircraft until scrapped in 1944.

Reconstruction Répliques Avions Anciens Mosquito .75

The French association Reconstruction Répliques Avions Anciens began work on 3/4-scale de Havilland Mosquito replica the replica in 1995 and required over 30,000 hours of work before it was ready for the first test at the Fontenay-le-Comte airfield.

The first engine test was carried out earlier this year and were then followed by high-speed ground tests. The first flight took place on April 23, 2011.

This replica of a British WWII bomber overturned on 6 August 2015 after touching the ground in Fontenay-le-Comte. The pilot is seriously injured.

Thursday evening, at 8:45 p.m., the plane approached an airstrip at the aerodrome of Fontenay-le-Comte, in the south-Vendée. This three-quarter-length replica of a Mosquito, a British WWII bomber, returns to its “base” after a commemoration, in Jonzac, in Charente-Maritime. On board: Hervé Thebaud, the pilot, an instructor from Île d’Yeu; and Jean-Paul Bichon, the co-pilot, a resident of Luçon, both in their sixties.

According to several witnesses, the landing “is going well”. Shortly after touching the ground, “a hundred meters from cutting the throttle”, during the “taxiing” phase, the aircraft got slightly askew. At this precise moment, it tilts forward, “like a wooden horse”, and completely overturns, until the fin hits the ground. He ends his race on his back.
An aerodrome mechanic is already running towards the aircraft. Seeing the aircraft’s turn signals still on, he said to himself that it was absolutely necessary to “cut the battery to prevent it from causing a fire” with the fuel escaping from the tank. It then contains “at least 400 liters of gasoline”.
When the mechanic arrives in front of the machine, the pilot and the co-pilot are aware and can press the button. The co-pilot is the first to exit, with the help of the mechanic who broke the window. The pilot was extricated after an hour by the firefighters, “quickly on the spot”. Seriously injured, he will later be directed to Nantes. Its vital prognosis is not engaged.
On the aerodrome, around thirty firefighters cover the aircraft with a carpet of foam. The last left at 12:30 am Several people, including the co-pilot who returned from the emergency room, then got busy to get the Mosquito out of the airstrip. It is when trying to turn it over with a crane that the tail, which was already hanging on by a thread, becomes detached. The plane had required 17 years of work. According to a member of the Luçonnaise association which built it (Replicas and reconstruction of old planes), it will be “difficult to repair”.

Ironically, the Mosquito had, the same day, flew over Jonzac in homage to the crew of an Allied bomber that crashed there on August 6, 1944.

Raytheon Hawker Horizon

Hawker Horizon

Raytheon’s biggest Hawker design (30% larger than the 800XP) originated at roughly the same time as the initial work began on the Premier I. The Horizon would be an effort to blend high technology with earlier Hawker flight characteristics.

First flown on 11 August 2001, the Horizon retains its DH125 pedigree but is an all-new aircraft with a thinwall composite fuselage offering some 20% more cabin space for the equivalent weight of a conventional structure. The Horizon complements the upgraded 800XP and the entry-level Premier 1.

The design received FAA certification in 2004. On the flight deck is a Primus Epic flight control system and flight management system. The navigation comes from a dual VHF omni-directional radio navigation system, dual distance measuring equipment, dual inertial navigation system and a dual global positioning system. Preliminary performance specifications for the 37,500-pound-MTOW, P&WC PW308A-powered twinjet include a 470-knot high-cruise speed, 3,366 nm NBAA IFR range (two crew and six passengers), and a 5,088 ft balanced field length.

More than 320 were ordered.

Queen Aeroplane Company Twin Monoplane / Speed Monoplane / Double Gnome Monoplane

Taken at Mineola airfield, the Queen Speed Monoplane / Double Gnome Monoplane; fitted with two Gnôme rotary engines of 50 hp – the two bladed propellers driven in opposite direction to prevent torque. Its design influenced by the Blériot monoplane (Queen built Blériot XI monoplanes under license at the time), the twin engine construction was thought to be safer, that in the case of malfunction of one, flight could continue using the other. The machine was financed by the banker Willis McCormick, who was president of the New York Aeronautical Society. Built in Fort George, New York in 1911, its first flight was made by Frank Stone on July 10, 1911. Unfortunately the machine was unstable during the climb, turned and crashed, injuring the fearless Stone. The machine was ruined, never to fly again.

Span: 26’4″

PZL PZL.30 / LWS LWS-4 / LWS-6 Żubr

PZL.30 Żubr

The LWS-6 Żubr (PZL.30, wisent / Bison) was a Polish twin-engined medium bomber, produced by the LWS factory before World War II. A short series was used for training only, because it was inferior to the contemporary PZL.37 Łoś design.

The PZL.30 was designed by Zbysław Ciołkosz) for PZL in the early 1930s, initially as a 12-passenger passenger airliner. When the Polish Airlines LOT bought Douglas DC-2 aircraft instead, the design was converted to a bomber, with a projected bomb load of 1,200 kg. The PZL.30 was developed as a less-advanced, alternative medium bomber design, in case the more modern bomber design, the PZL.37 Łoś would fail. The first prototype, designated PZL.30 (or PZL.30BI) was flown in March 1936 by Bolesław Orliński.

The maiden flight of the PZL.30 took place only three months before the PZL.37 Łoś prototype flew. Although developed at the same time as the PZL.37, the PZL.30 was inferior to its counterpart, being slower, had a much smaller bomb load than the Łoś and yet was produced at a similar price.

The PZL.30 prototype, initially powered with two 420 hp Pratt & Whitney Wasp Junior engines, was further refitted as the PZL.30BII, with more powerful Bristol Pegasus VIII engines. The aircraft was accepted for a limited production run by the LWS state factory in Lublin, of which Ciołkosz became the technical director and project lead. The second prototype was designated LWS-4.

It was planned to produce 16 aircraft for the Polish Air Force, with the designation: LWS-6 Żubr. The Żubr was given a military code number 71 and the series was to have factory numbers 71.1 to 71.17, but the aircraft were given different code numbers eventually due to secrecy.

The production aircraft incorporated further changes, among others the landing gear retracting into the fuselage sides was changed to more conventional one, retracting into the engine nacelles. After a prototype crashed on 7 November 1936, caused by de-laminating plywood wing skins, the wing had to be reinforced. Due to this increased weight, the LWS-6 had a smaller bomb load than expected. A modified prototype was made with a double tail fin, and flown at the end of 1937. The definitive variant, however, in the course of production, returned to a single enlarged tail fin configuration. A series of 15 aircraft were built in 1938.

In 1937 the factory proposed to build a floatplane torpedo bomber variant LWS-5, instead of developing LWS-1 (R-XXA) design by Jerzy Rudlicki. It was supposed to be fitted with two Short floats of the Lublin R-XX prototype. At first the Polish Navy exhibited interest and work on the LWS-1 was cancelled despite its progress, but then due to problems with LWS-5 development, work on the prototype was canceled. It was evident that the underpowered LWS-5 could not carry an effective offensive load.

Apart from the Polish Air Force, the Romanian Air Force showed an interest in the Żubr prototype in 1936, and considered a purchase of 24 aircraft. On 7 November 1936, after the Pegasus-powered prototype encountered a mid-air structural failure and crashed at Michałowice, all on board dying, including two Romanian officers on board, Romania ordered the PZL.37 Łoś instead.

The LWS-6 was a conventional high-wing cantilever monoplane. It featured mixed construction (metal and wood). The fuselage was rectangular in cross-section, made of a metal frame, covered with metal (upper fuselage) and canvas (sides and bottom) with the front section made of duralumin. Wings were of wooden construction and plywood covered. There was a crew of four: pilot, commander-bombardier, radio operator and a rear gunner. The bombardier was accommodated in the glazed nose, with a forward twin machine gun turret with a notable pointed “beard” below the turret. The pilot’s canopy was located above the fuselage, offset to the left. The rear gunner operated twin machine guns in a semi-retractable upper dorsal turret, elevating to a working position, along with a “trap” ventral position, operating the same way. The main undercarriage retracted into engine nacelles. The aircraft was powered by two Bristol Pegasus VIII radial engines, normal power: 670 hp (500 kW), take-off power: 680 hp (520 kW). Bombs were carried in a bomb bay in the fuselage, the maximum load was 660 kg.

A total of 15 LWS-6 bombers were delivered to the Polish Air Force in 1938-1939. From the outset, they were considered obsolete, and were assigned to training units, mainly to the 3rd Training Dyon. In operational service, the LWS-6 revealed several faults, for example, the undercarriage retracted on some aircraft during landing. Reportedly, the crews later flew with the undercarriage permanently locked down. As training aircraft they had their armament removed. There was only one crash, without fatal injuries.

During the invasion of Poland in 1939, Żubrs were not used in combat. Several were destroyed on the ground, along with many other training aircraft. The Germans captured several LWS-6s, including the twin-tailfin prototype, and used them for blind flying training until at least 1942 (among others, in Blindflugschule Schleissheim). Ironically, the Luftwaffe service of this bomber was longer than the Polish one.

The Soviets captured four aircraft after their invasion on Poland and subsequently used them as communication aircraft.

Production started in 1985 and 20 early aircraft supplied to Aeroflot from 10 August 1988, but subsequently returned to Swidnik, most being reallocated to Heliseco for firefighting in Spain. The first batch of 50 had been built by mid-1991 and a further batch of 20 were under construction.

Polish (26 March), Spanish, US (31 May) and German (6 December) FAR Pt 29 (VFR) certification of W-3A received 1993. On 31 May 1993, it became the first Eastern bloc helicopter to be awarded FAA certification. Polish ICAO-standard noise certification 1995. At 1994 prices, a basic W-3A was available tor US$2.5 million.

Polish civil W-3 users include the Interior Ministry, a telephone company and a cardiac hospital.

By 1 January 1996, excluding prototypes, 85 W-3s had been built by PZL, and the 100th example was completed in 1996. MoU 13 April 1996 with Daewoo, South Korea (later part of KAI), for purchase of 35 Sokols with marketing rights in Asia, but payments (and hence deliveries) delayed due to regional economic difficulties. Korean agreement expired April 2003 and not renewed by July.

The Sokol has been delivered in quantity to the Polish military forces (40 examples) and to Myanmar (12), Korea (3) and the German Border Police (6).

Polish armed forces versions including W-3RM Anakonda for air/sea rescue, and W-3W Sokol and similar W-3WA each with 23 mm cannon and outriggers for missiles, rockets and other weapons.

September 1998 co-operation agreement between Swidnik and Euromissile led to integration of HOT 3 ATM on Sokol, followed by successful firing tests during demonstration of HOT/Viviane system at Polish firing range in Nowa Deba on 4 March 1999, using Swidnik trials aircraft SP-SUW (c/n 360318). This aircraft utilised in 2000 as prototype to test new main rotor blades with modified leading-edges and increased damage tolerance. Swidnik continues to offer W-3/HOT 3 variant as potential export version, but domestic requirement for W-3H now shelved in favour of a 50-aircraft support role upgrade of existing Sokols, attack requirement instead being met by upgrading Mi-24 fleet.

A total of 143 (excluding five flying prototypes and four static test airframes) were completed by early 2001, of which 131 then in service. Three reportedly purchased in early 2002 by Ukraine Border Guard. However, no new production reported from early 2001 until at least mid-2003.

The basic VFR, single-pilot W-3A in 2002 cost US$3.156 million.

Under a Polish MoD contract of October 2002, valued at approximately US$22.8 million, PZL-Svidnik is to upgrade 16 W-3W and 12 W-3WA Sokols from 1994/2000 production to NATO-compliant (STANAG 4555) standard with Rockwell Collins AN/ARC-210 U/VHF radios, Bendix/King KLU 709 Tacan, and cockpit instrumentation compatible with the pilot’s Litton M927 NVGs. The contract was due for completion by 2006.

PZL Mielec I-22

Launched 1977, leading to 1980 Polish Ministry of National Defence Iskra-22 requirement for combat-capable jet trainer. The I-22 prototype made its first flight on March 3, 1985 and the type was revealed in October 1986 as a twin-jet advanced trainer/light-attack aircraft.

PZL Mielec I-22 Article

First production order (for nine aircraft, only five of which were completed in I-22 configuration) announced September 1991; first of these (serial number 103) made first flight 5 May 1992, handed over to Polish Air Force (with second aircraft 105) 24 October 1992; next three (201, 202 and 203) delivered February 1994 (203 since lost).

Reappraisal in 1995 indicated that I-22 with PZL-5s was underpowered, and the four survivors were due to be upgraded to M-96 standard during 1996-97 (K-15 engines, Martin-Baker seats and improved avionics). Earlier proposal to suspend Iryda development and buy 36 ex-German Alpha Jets was reversed in December 1995; funding concentrated instead on M-93K improvements and evaluation of M-96. The five survivors were delivered to PZL for conversion.

Equipment includes a ventral 23mm gun pod, four underwing hardpoints for up to 2,000kg of stores, a nose-mounted 13mm camera gun, 1FF, and a radar warning receiver. The landing gear is designed for rough-field operations and provision is made for a brake parachute.
