The BICh-11 appeared in 1932 as a continuation of the trapezoidal wing design started with the BICh-8 glider. Its construction was developed in the TsAGI workshops. The Cheranovski BICh-11 (RP-1) (Russian: Черановский БИЧ-11 (РП-1)), conceived in 1931, became the world’s first experimental aircraft in a flying wing configuration designed to use a reactive power plant. Problems with the development of the reactor made it necessary to equip the BICh-11 with a low-power engine in pusher configuration.

In practice, the BICh-11 had been conceived to test in flight the OR-2 liquid propellant rocket engine developed by FA Tsander, which weighed only 18 kg and was capable of developing a thrust of 0.62 kN. The funds for the modification of the model and the installation of the reactive power plant were approved by OSOVIAJIM on February 25, 1932. The installation of this engine was just behind the cabin. The fuel and oxidizing agent tanks were designed in fairings located on the wings, on both sides of the central fuselage.

The BICh-11 was conceived as a single-seater experimental glider, built entirely of wood. The cantilever and high-set wing had a trapezoidal shape and a three-spar structure. This wing was conceived in three sections: a central one forming an integral part of the fuselage and the long wing consoles with the rudders at the ends. The union of the consoles to the centroplane was made by means of some steel pieces. In the centroplane, they conceived some fairings that contained the chemical components necessary to make the OR-2 liquid reactive engine functional.

The entire leading edge was covered with a 1mm thick plywood sheet. The straight trailing edge featured control surfaces along the entire span, located on a bar on the soffit of the wing, just below the trailing edge. In the external part the ailerons were located, also used as elevator rudders. On the inside were the adjustable stabilizers on the ground and a little further inside the elevator. Adjustable stabilizers on the ground were located on the inside.

The fuselage was covered with plywood. The landing gear was composed of two independent wheels and a tail skid.

The pilot was located in a closed cockpit at the nose.

In mid-February 1932 the BICh-11 was transported to the GIRD and on February 22 it was flown in the form of a glider by Sergei Koroliov. Also in glider form, the BICh-11, piloted by Koroliov, flew in the IX National Sailing Competitions held in 1933.

The first tests work jet engine OR-2 began the 18 of March of 1933, but only 10 days after FA Tsander died and with him the work of building the rocket plane – 1 (RP-1), assigned name to the project.

Given the lack of a power plant, the BICh-11 was modified to use a 27 hp ABC Scorpion piston engine driving a propeller, with which the tests were continued. In this configuration the BICh-11 flew satisfactorily, becoming one of the first airplanes in a flying wing configuration with a trapezoidal ground plan to do so.

In the version with a piston engine, some modifications were made to the wing plan and its control surfaces. The ABC Scorpion power plant was located at the end of the fuselage fairing as an extension of the cabin and powered a two-bladed wooden propeller.

Cheranovski SG-1 / SCR-21

During the design of the new SG-1 racing aircraft (SCR-21), designer Boris Ivanovich Cheranovsky applied a trapezoidal wing shape but with a broken leading edge. The center-wing was straight and the outer had a swept 25º. By the front view, the wing was a “reverse gull”, and tailless.

The very short fuselage had a length with a rudder of no more than 4,74 m. The drop-shape of the pilot’s cabin, along with the fuselage with a hexagonal cross section in the cockpit area, was continued back to the wedge-shaped vertical tail.

The take-off weight of the SG-1 was 643 kg with empty 526 weight. The take-off and landing characteristics turned out to be outstanding. The “screen” effect reduced the landing speed to 80 km / h, and the take-off and landing respectively 110 and 100 m. It was calculated with the forced motor MB-6А (240 hp) to reach 424 km / h.

Such unusually large numbers caused a critical attitude to the project of some aerodynamics and designers. The plane was predicted of a fiasco, but some experts gave positive feedback, among them – Brig. VS. Pyshnov Mr. I rank engineer A.S. Yakovlev.

Due to the complexity of the engine supercharging system, its power, like that of the serial MB-6, was only 220l.s., and on flight tests it was possible to achieve 417 km / h. But this is only 7 less than the estimated speed. SG-1 tests were completed by the summer of 1941.

Cheranovski BICh-7

BICh-7

The BICh-7 (Russian: Черановский БИЧ-7) appeared as an enlarged BICh-3 development with a more powerful 100 hp Bristol Lucifer engine and the fuselage featured two open cockpits in tandem.

At the wingtips, on the upper surface, rudders were located with a curved leading edge.

The landing gear featured a single center wheel with skids on the tail section and near the wingtips. This landing gear proved ineffective, as did the dolphin-fin rudder.

Designed by Boris Ivanovich Cheranovski the BICh-7 was built at the Air Fleet Academy in 1929.

As a result, the plane did not take off. After several unsuccessful attempts, the model would be modified to give rise to the BICh-7A.

Based on the unsuccessful BICh-7, Cheranovski modified the cell to become a two-seater with a closed cabin. The rear cockpit fairing made a smooth transition to a rudder, which was very effective in this version. The BICh-7A (Russian: Черановский БИЧ-7A) signified the continuation of the development of the original Cheranovski parabolic scheme.

Cheranovski BICh-7A

Like most of Cheranovski’s designs, the BICh-7A was built entirely of wood with a fabric covering.

The cabin on this model appears closed and ends at the rudder. The wing, with a thick profile, presented an area increased to 30 m².

Another notable feature was the modification of the landing gear to a conventional two-wheel configuration with independent landing gear and tail skid.

The wing profile was also slightly modified and the system of ailerons and elevons installed on a bar located near the trailing edge of the wing intrados was introduced. This configuration had been successfully tested on the BICh-5 during the experiments carried out in the TsAGI wind tunnel and resulted in an increase in the effectiveness of these surfaces and in the maneuverability of the aircraft.

Cheranovski BICh-7A.

The BICh-7A was completed by 1932. The tests carried out in 1932 confirmed the expectations of its builder.
The flights carried out by the pilot NP Blagin showed that the new airplane responded positively to the controls and presented good stability both longitudinally and during turns. These flights reached a maximum speed of 165 km / h with a ceiling of 5000 meters. Landing speed remained in the range of 70 – 75 km / h.

The main problem with the BICh-7A was its engine. Attempts to install a more powerful 140 hp three-cylinder Bristol Lucifer unit brought no improvement. During the flights the pilot was forced to adjust the power to 100 hp due to the appearance of strong vibrations. Low engine power and the use of an imported engine limited the model’s production possibilities. The M-11 domestic engine was never tested in the BICh-7A.

The excellent results of the BICh-7 would lead Chizhevski to develop in the Bureau of Special Constructions (BOK) a model of a flying wing that was known as BOK-5.

Chengdu FC-1 / JF-17 Thunder

The origins of the ‘Super-7’ can be traced back to 1986 when Pakistan and China wanted to modernise the J-7 with western avionics and engine. The project was named ‘Saber II’ by the PAF and would replace its F-6s. In January 1987, Grumman Aerospace was seleted as primary contractor and several other western firms competed to provide the engine and avionics. By 1989 the projected costs had significantly increased (some sources say 40%) and was deemed a highly financial risk by the Pakistan Air Force. On top of that, Chinese relations with the west broke down. Subsequently the contract was cancelled.
Chengdu continued the development under the new designation FC-1 (Fighter China-1) aimed at creating an affordable fighter for the export market. In 1995 Pakistan regained interest in a joint development with China. The 1993 US sanctions prevented the PAF from acquiring Western technology or weapons. In June 1999, China and Pakistan signed the joint development and production agreement to co-develop the FC-1. Chengdu was selected as primary contractor and the Russian Mikoyan Aero-Science Production Group (MASPG) was contracted to provide the Klimov RD-93 turbofan engine and design assistance too.
The FC-1 design has little in common with the J-7 and is believed to be based on Mikoyan’s concept for a single-engine fighter based on the MiG-29. The FC-1 also shows features from the F-16 design, although the layout is somewhat more conventional.

The FC-1/JF-17 multirole combat fighter platform was developed jointly by the Chengdu Aircraft Industry Corporation and the Pakistan Aeronautical Complex to produce a cost-effective, multi-faceted airframe to use modern avionics and weapons packages for the Pakistani Air Force – essentially a modernized “budget fighter”.
As such, the FC-1 Xiaolong (“Fierce Dragon”)/JF-17 Urdu (“Thunder”) was begun – the former being the Chinese designation while the latter being the Pakistani designation. The joint program began loosely in 1998 and became a formalized agreement in 1999. The initial prototype was available and made airborne by 2003. Follow-up testing and revisions ensued and a newer prototype form flew in 2006. All testing was handled in China until 2007 saw deliveries of examples for evaluation by the Pakistani Air Force. Evaluation proved favorable and the Pakistani Air Force officially accepted the aircraft into service under the designation of JF-17 “Urdu”. The first operational squadron was formed in February of 2010.

At least 150 examples were on order and the total PAF inventory may grow to 250 total aircraft in service.

JF-17

The FC-1/JF-17 was initially conceived in three single-seat prototypes known simply as the PT-01, PT-02 and the PT-03. The first FC-1 was rolled out on 31 May 2003. It made its first flight on 24 August 2003, although some say 2 or 3 September 2003. It was quickly followed by a second airframe (PT-2) for static tests and two more flying prototypes. The third prototype PT-3 has joined PT-1 in the flight testing program on 9 April 2004. These were followed into development by the revised single-seat prototypes encompassing the PT-04, PT-05 and the PT-06. From the PT-04 prototype, the single-seat production form was born and is now known under two distinct designations as the “JF-17 Urdu” (in Pakistan service) and the “FC-1 Xiaolong” (in Chinese service). To follow will be a two-seat mount that will double as both a pilot trainer (fitting the student in the forward cockpit with the instructor in the aft cockpit) that will make use of less internal fuel stores and a dedicated strike fighter.
The Chengdu FC-1/JF-17 makes use of a cylindrical fuselage with the cockpit set well-ahead on the airframe. The front of the fuselage was capped by a nose cone assembly housing the radar. The cockpit is covered over in a single piece canopy with a forward piece. Intakes feed a single powerplant buried within the fuselage. An intake is mounted to either side of the airframe just below and aft of the cockpit with small bulges ahead of each opening to help induce airflow. Wings are mid-set along the sides of the aircraft and feature highly-swept leading edge surfaces. The wings have underwing pylon hardpoints and wingtip missile launchers. The fuselage spine conforms to become the base of the single vertical tail fin atop the empennage. All-moving horizontal tailplanes are set to either side of the empennage. The engine exhausts at the extreme rear. Some of the integrated avionics are set in a rear package, appearing as a rounded protrusion just above the jet exhaust ring and at the base of the vertical tail fin. A pair of ventral strakes can clearly be seen at the base of the empennage. The FC-1/JF-17 makes use of a fully-retractable tricycle landing gear featuring two single-wheeled main landing gear legs as well as a single-wheeled nose landing gear leg. Construction of the airframe is of semi-monocoque format and made up of aluminum alloys as well as utilizing titanium allows and steel in certain high-stress areas. Control surfaces are under the control of a digital flight control system while the pilot has HOTAS configuration (Hands On Throttle and Stick).

JF-17

The Chengdu FC-1/JF-17 makes use of a single Klimov RD-93 turbofan engine delivering 11,106lbf of standard thrust and up to 18,973lbf of thrust when utilizing afterburner. Maximum speed is listed at approximately March 1.8 or about 2,205 kilometers per hour. The FC-1/JF-17 has a ferry range of up to 2,175 miles with a combat radius of 840 miles. Service ceiling is listed at 54,790 feet.
Standard armament is a fixed, forward-firing 23mm GSh-23-2 twin-barrel cannon of Russian origin. This can be replaced with the larger-caliber 30mm GSh-30-2 series cannon at the expense of ammunition. The FC-1/JF-17 has seven hardpoints. Hardpoints include the wingtip launchers (reserved for short-ranged air-to-air missiles), four underwing stations (the two innermost plumbed for fuel stores) and a single fuselage centerline location, this also plumbed for external fuel stores. The FC-1/JF-17 can sport an underfuselage tank of 800 liters while the two underwing stations can carry either 800 liter or 1,000 liter fuel.
The FC-1/JF-17 makes use of a NRIET KLJ-7 series multi-mode fire-control radar that handles tracking and engagement of targets, even at beyond visual ranges. Range is approximately up to 75 kilometers on its X-band frequency.

In February of 2010, the Pakistan Air Force had at least fourteen JF-17 “Thunder” operational examples, these with the 36th Tactical Attack Wing out of PAF Base in Peshawar. These Thunders are under ownership of the No. 26 Squadron known as the “Black Spiders”.

In late 2009, the FC-1 was known to have passed a procurement hurdle in China that seems to indicate that the Xiaolong will, at some point, arm the People’s Liberation Army Air Force in the near future.

JF-17

The JF-17 began small-batch deliveries to China in 2006. Pakistan received their first aircraft six months later, reaching operational status in 2010. Pakistan has already put the type to use, flying it against targets in South Waziristan. The Chinese seem to be operating fewer JF-17s than the Pakistanis, but development is already underway for an improved Block 2 variant, intending to incorporate more composites into the structure, as well as newer avionics and an IRST. Many countries, particularly in Africa and the Middle East, have expressed interest in the JF-17. While there have been tentative talks with Zimbabwe, Argentina, and Egypt to procure the aircraft, however, no purchases have materialized. More recently, Nigeria has looked into buying several JF-17s from Pakistan, but an actual order has yet to occur. According to the chief designer of the JF-17, this is due to a combination of political factors and the fact that the JF-17 just can’t compete with contemporary Gen 4 fighters. It is a great budget replacement for the MiG-21 (unit price of ~$20 million), it lacks the capabilities that countries are looking for in a fighter.

PAC Kamra has delivered nearly 120 JF-17 Block I and II fighter jets to the PAF since 2009. Since its induction in the PAF in 2007, the JF-17 has been upgraded several times. The JF-17, with a service ceiling of 50,000 feet and a peak speed of around 1,200 mph, can carry out a variety of tasks, including aerial intercept and ground assault. It can hold around 7,000 pounds of ordnance on seven hardpoints and is equipped with a single twin-barrel 23 mm autocannon.

Pakistan JF-17

The JF-17 is only in service with three countries — Pakistan, Myanmar, and Nigeria. In December 2023, PAF inducted the latest Block III variant into its fleet.

Chengdu J-10 (Vigorous Dragon) / F-10 Vanguard

With funding in place several years before actual development of the aircraft began, the official call came in the form of Project 8610 – the requirement for an indigenous Chinese air superiority fighter to combat similar fourth generation systems in Russia and the West.
The J-10 program increased in 1986 under the guise of the Chengdu Aircraft Design Institute. Designed by 611 Aircraft Design Institute, Chengdu, the J-10 (Jian-10 meaning Fighter-10) built by Chengdu Aircraft Industry Corporation (CAC) is a multi-role fighter for the China’s Peoples Liberation Army Air Force (PLAAF). The J-10 is to replace the older J-7 and Q-5 attack aircraft.
The Project 8610 aircraft development was launched by No.611 Research Institute in October 1988, following approval the previous month. The Chengdu J-10 started as a development of the IAI Lavi, although little of the original Lavi design remains, and features a compound delta-wing design with canards placed higher in front of the main wing and behind the canopy. The light weight airframe is powered by the Russian built AL-31FN engine, which is a modification of the Su-27 and Su-30 AL-31F power plant. The J-10’s AL-31FN engine is not equipped with thrust vectoring. According to Russian reports, China ordered 100 AL-31FN engines to support J-10 production in July 2005, having received 54 engines between 2002 and 2004 for the initial production batch. The main engine intake is located on the belly and has a rectangular shape.

Chengdu J-10 Article

The J-10 was originally designed around an indigenous Chinese powerplant designated as the WP-15, a turbojet type engine. Support for the engine project was eventually dropped so the Chinese found a solution in the Russian-made Salyut AL-31F turbofan as a comparable replacement. The Russian engine featured a thrust output of up to 27,557 with full afterburning and was essentially a specially-modified version of the AL-31F series that has powered the Sukhoi Flanker family.
While the Russian engine selection has proven successful for early J-10s, the Chinese have once-again taken to develop their own in-house engine with the WS-10A. Though a little larger and lower-rated than the Russian AL-31 series, the 24,729lb thrust (with full afterburn) is a capable propulsion system that makes marketing the J-10 to foreign air forces that much easier for the Chinese (as opposed to receiving clearance from the Russians in re-selling the J-10 with Russian technology).

The J-10 makes use of a “tail-less” delta wing configuration (with forward situated canards). The delta wings are low-mounted monoplanes with gradual sweep back that run along more than half the length of the fuselage sides. Ventral strake-type fins are added at the main wing bases to the extreme end of the fuselage. The fuselage itself is quite tubular in appearance when view in forward profile and comes with a conical nose (housing the radar array) assembly fitted just forward and below the high-mounted cockpit.
The cockpit features a two-piece curved canopy hinged at the rear. Entry to the cockpit is standardized from the portside via a ground-based step ladder. In the two-seat J-10, an instructor occupies a raised rear cockpit position seeing over and past the student’s forward cockpit position. The entire cockpit area is therefore lengthened and both crew sit under a longer, two-piece canopy hinged at rear with a heightened dorsal spine for the additional avionics needed in the second cockpit. The pilot controls the J-10 through a conventional HOTAS (Hands-On Throttle and Stick) arrangement and sits in a “zero-zero” ejection seat – allowing for powered ejections at “zero” speeds and at “zero” altitudes for ultimate safety. The cockpit is dominated by three large liquid crystal multi-function displays (MFD) that help de-cluster the instrument panel while aiding in the pilot’s workload.
Canards are fitted to either side, aft and below the cockpit- and add forward stability. The forward fuselage elegantly contours into the base of the single large-area vertical tail fin adorning the empennage. The lack of horizontal planes on the tail mean that the main wing assemblies straddle either side of the engine exhaust at rear. A static fuel probe is situated to the forward starboard side of the fuselage. Construction of the fuselage includes use of composite materials throughout.
One of the more distinct design elements of the J-10 is the rectangular under-fuselage intake opening feeding the single engine. The undercarriage is of a conventional tricycle arrangement made up of two single-wheeled main legs and a two-wheeled nose leg. The nose landing gear is fitted under and aft of the intake opening and retracts backwards in a housing. The main landing gear legs retract in a forward fashion along the sides of the fuselage at about amidships.

The aerodynamically unstable design is controlled by a digital fly-by-wire system. The cockpit is fitted with three multifunctional displays (MFD) and a wide-angle HUD. Also there is evidence that a Helmet Mounted Sight (HMS) will be incorporated.
Standard armament for the J-10 is a twin-barrel Type 23-3 23mm cannon (offset to port under the intake near the nose landing gear) and eleven hardpoints made up of six underwing (three to a wing) and five under-fuselage positions. The five underfuselage positions include a centerline hardpoint, a pair of forward-mounted hardpoints (near the intake opening) and a pair of aft-mounted hardpoints (about mid-fuselage) all centered around the external structure that makes up the intake assembly. Total munitions load has a reported limitation of up to 9,900lbs.
The J-10 can sport up to 3 x external jettisonable fuel tanks for increased operational ranges. One such implement is carried along the centerline fuselage (about 450 gallons) whilst the other two can be fitted on cleared underwing hardpoints (212 gallons each).
The J-10 can be armed with the Russian R-73 and R-77 or Chinese PL-8, PL-10, and PL-11 air-to-air missiles as well as a wide variety of air-to-ground weapons. Also it was reported in June 2005, that the J-10 has completed integration testing of China’s new PL-12 (SD-10) active guided air-to-air missile. Although the J-10 development program started with the aim for creating a fighter, after selection of the J-11 the main focus has been on increasing its air-to-ground capability. The J-10 will also be able to carry Chinese developed anti-ship and anti-radiation missiles.
The first prototype ‘1001’ made its first flight on 22/23 March 1998 by test pilot Lei Quiang. The flight lasted all but 20 minutes. Following the first prototype another 8 prototypes have appeared. The second prototype ‘1002’ was lost in a fatal accident in late 1997, and also the third prototype ‘1003’ had crashed in a fly-by-wire incident.
Six production examples soon followed the prototypes, in 2002 the first pre-production aircraft making its maiden flight. From there, after some 18 years of total development time, the J-10 culminated in an official clearance for operational service and was delivered to the PLAAF on 23 February 2003 when the first 10 J-10s joined the 13th Operational Trials Regiment of the Flight Test and Training Centre at Cangzhou-Cangxian.
The type was declared operational in December 2003. The PLAAF’s 3rd Test Flight Regiment started operating the J-10A from the Chengdu factory airfield at Wenjiang in 2004. The 44th Air Division’s 131st Fighter Regiment at Mengzi, Yunnan, became the first operational J-10A unit on July 13, 2004, and had received 32 J-10As by 2005. Also the division’s 130th Fighter Regiment is reportedly being equipped with the J-10. A third fighter regiment was equipped with the J-10 in early 2006.

The J-10 would be declassified at the Zhukai Air Show in November 2006, but the aircraft’s appearance was cancelled reportedly due to safety concerns. On December 29, 2006, however, China’s state-run Xinhua News Agency officially confirmed that the Chengdu J-10 is in operational service with the PLAAF. The same day, China Central Television (CCTY) broadcasted footage of the aircraft firing air-to-air missiles, air-to-ground weapons and undertaking aerial refuelling with a Xian H-6 tanker.
The aircraft was officially introduced in 2005, unveiling nearly two decades of secrecy and denials by the Chinese government, and solidified the Chinese nation as a premier developer of air arms for the foreseeable future. Some 100 production examples were delivered to the People’s Liberation Army Air Force from 2004 into 2006 and current totals of this aircraft in the Chinese inventory range from 120 to 160 examples with some 300 believed to be required. Production has been handled by the Chengdu Aircraft Industry Corporation (CAIC), overseers of the firm that designed the J-10.
The J-10 is rated as a Mach 2.2-capable fighter platform and the airframe can sustain up to 9 positive and -3 Gs. Maximum range is limited to 2,113 miles without droptanks or in-flight refueling (accomplished via a probe) while a service ceiling of 65,600 feet is reported.
The J-10 has been developed into a handful of variants. The J-10A remains the principle single-seat multirole aircraft platform and is marketed under the designation of F-10A for export.

Further developments include a two-seat trainer, twin engine variant, and a dedicated air-to-ground version with a redesigned nose section. In November 2004 Air Forces Monthly published a recent photograph of the what is believed to be the first two-seat J-10 (believed to be designated J-10B, but J-10S has also been reported) that had begun test-flying. It is believed development of the two-seat trainer was started in 2000 and that the first flight of the two-seat J-10B took place on December 26, 2003. The forward fuselage of the aircraft was stretched to accommodate the additional cockpit. Reportedly the J-10B is combat capable and can be used as airborne command & control aircraft with the formation commander occupying the rear seat.
The J-10S is the two-seat version suitable for training J-10 pilots-to-be yet they retain the full ground strike capabilities of the base J-10A multirole fighter. The J-10B is thought to be an upgraded version of the base J-10 and feature a distinctly redesigned intake opening, revised ventral fins and a redesigned vertical tail as well as an integrated infra-red search and track sensor. A new nose assembly is also reportedly housing an all-new radar suite.

It is also reported a more advanced version is under development. The new J-10 version is reportedly called the Super-10, and has a more powerful engine, thrust-vector control, stronger airframe and passive phased-array radar.
China is believed to have a requirement of 300 aircraft of the type. On April 12, 2006 the Pakistani cabinet approved the purchase of at least 36 J-10s under the designation “FC-10” (FighterChina-10).

The Pakistani Air Force remain the only other (presumed) operators of the J-10 and designate their systems as the F-10A/B Vanguards. At least 32 to 40 J-10s are known to have been purchased with deliveries beginning in 2009. Pakistan has already made clear their intent to purchase more FC-20s in the future.

The J-10C was inducted in Pakistan’s Air Force in March 2022 to counterbalance India’s procurement of French-built Rafale fighter jets. Pakistan has been calling the Chinese jet the “Dragon from the East.” The omni-role aircraft is armed with an advanced electronics warfare suite. The J-10C’ Vigorous Dragon’ all-weather fighter aircraft and can be equipped with a variety of 4th-generation air-to-air missiles, including the Chinese PL-10 short-range missile and the PL-15 beyond visual range missile.

 Pakistan’s J-10C

The J-10C in Chinese service has notable features like an infrared search and track and laser rangefinder dome in front of the cockpit, as well as a glass cockpit with a wide-angle holographic head-up display. It is also equipped with an Active Electronically-Scanned Array (AESA) radar.

Chengdu J-9       

The J-9 used a completely new single-engined design. It was to have a top speed of Mach 2.4, necessitating the use of variable geometry inlets and a high-power turbofan engine. Four configurations were considered, all incorporating delta wings. However, each proposed configuration was found to lack agility and experience stability issues at certain speeds. A new configuration was devised, resembling the canard layout of the Saab Viggen. However, just as this major change was made, the Cultural Revolution hit the project, bringing work to a standstill. Meanwhile, Chinese involvement in Vietnam led to rapidly changing requirements, calling for unrealistic range and top speeds higher than originally specified. Work resumed in the 70’s, with a prototype reportedly making a flight. However, the WS-6 turbofan that was to power the aircraft proved a failure, and the competing Shenyang J-8 was not only entering service but was more promising. In 1978 the J-9 was finally cancelled.

Chechet ChUR-1

The 1911 ChUR-1t was built by Russian aviator Nikolaj Vasilievich Rebikov and inventor Grigory Gerasimovich Chechet with financial support of M.K.Ushkov of Moscow.

It was demonstrated on the Second Moscow Aviation Exposition (Mar 25 – April 8, 1912), later – flown on Comendant Airfield near St.Petersburg.

It was a ‘inverted’ biplane (upper wing was much smaller than the lower one) with biplane tail planes. Ailerons were only on the upper wing, during tests – added to the lower one too. Wings were equipped with anti-slide surfaces.

The first aircraft in Russia to have steel wielded frame in front fuselage. Additional control surface was added to the tail in order to compensate load on the control stick.

On July 5 1912 the aircraft (flown by N.V.Rebikov) was crashed and not restored.
