The most mysterious and auto coded misile Russian fighter aircraft

Su-47 “Berkut” (S-37) (NATO: Firkin) – Russia’s long-term project based fighter developed in the OKB. Sukhoi. Fighter Wing has swept in airframe widely used composite materials.

Chief designer – Mikhail Pogosyan

History of creation

The project was developed first as a promising model fighter with CBS for the Soviet Air Force (modernization of the Su-27, the theme of the C-37) in the framework of the sectoral research program since 1983, but this topic has been closed in 1988. After that, the customer of the project of the Soviet Navy, which predetermined the further development of the project as a promising aircraft for aircraft carriers. The project was renamed and called the Su-27km (ship modified). Further, after the collapse of the Soviet Union and the crisis in the country in the 1990s, with the government funding of the project it was filmed and it lasted only through its own funding OKB “Sukhoi”. In the end, after all the twists and turns, the aircraft was unveiled at the MAKS-1999 under the name of S-37 “Berkut”, but to the MAKS-2001 renamed Su-47 “Berkut”. In 1997 he built the first flying of the Su-47, now it is experimental.

Proceedings

The airframe is made with extensive use of composite materials (CM). For example, the wing of the aircraft is made of carbon fiber-based KM enterprise “CVTs” Technology “.”Application of advanced composites provides increased load ratio of 20-25% of the resource in the 1.5-3.0 times, utilization of materials up to 0.85, reducing the labor costs for the production of parts by 40 = 60%, as well as obtaining the required thermal and radio characteristics. At the same time experiments conducted in the United States under the F-22A, indicate lower survivability of structures made of CFRP in comparison with the structure made of aluminum and titanium alloys that withstand high pressure and stall.

Design

“Berkut” is made on the aerodynamic configuration “longitudinal triplane integral” with forward-swept wing (CBS). Wing is blended with the fuselage, forming a single carrier system. The special features include advanced layout wing nodules, which are placed under the unregulated air intakes of engines having a sectional shape similar to a circle sector.Wing fighter has developed root portion (about 75 °) and the angle of sweep replaceable (about 10 °) on the front edge and seamlessly interfaced with her arm portion forwardswept (on the leading edge – about 20 °). The wing is equipped with flaperons occupying more than half the span and ailerons. All-moving canards (PGO) span about 3.5 m has a trapezoidal shape. Its sweep angle on the leading edge – about 50 °. Rear horizontal tail a relatively small area also holds tselnopovorotnym, with a sweep angle on the leading edge of the order of 75 °.

Avionics

The project assumed that the car will apply the most advanced avionics – digital multichannel desu (on the first plane – analog), an automated integrated control system, navigation system, which includes INS laser gyro, combined with satellite navigation and a “digital map “already found application in such machines as the Su-30MKI, Su-34 and Su-27M. It was planned to equip an integrated life support system and the bailout of the crew of the new generation.To control the aircraft as the Su-37, probably used malohodovaya lateral control stick and throttle strain (on the first plane central Uzbekistan).

Placement and size of antennas avionics testify to the desire of designers to provide all-round visibility. Apart from the main radar placed in the nose fairing under orebryannym fighter has two antennas rearview established between the wing and the engine nozzle.

Weaponry

A copy of the Su-47 is experimental. It was created to work out schemes airframe layout solutions and materials, so the weapons could not be taken without further modernization of the aircraft. During the development of Sukhoi PAK FA, airframe of the Su-47 was upgraded and got a bomb bay, the experience of the creation of which was subsequently applied to the PAK FA.
During development it was planned that the “main caliber” fighter, obviously, will be controlled by medium-range missiles such as RVV-AE with an active radar system end-homing and optimized for placement in the cargo compartments of aircraft (they have a wing of small extension and folding grid fin). SPA “Vympel” has announced a successful test flight of the Su-27, an improved version of this missile, equipped with a sustainer ramjet engine. The new modification has increased range and speed.
The importance of arming aircraft and missiles should have a class “air-to-air” short range. At the MAKS-97 demonstrated a new missile of this class, K-74, created on the basis of SD P-73 and differs from the advanced thermal homing system having an angle capturing the target, increased from 80-90 ° to 120 °. Applying new thermal homing (CBC) also made it possible to increase the maximum range of lesions by 30% (to 40 km).
Perhaps, as part of on-board armament promising fighters will be saved and a 30-millimeter cannon GSH 301.
It was planned that as well as other domestic multipurpose aircraft – Su-30MKI fighters, Su-35 and Su-37, the new machines will be held and strike weapons – precision SD and CC class “air-land” to destroy ground and surface targets as well as radar enemy.
