Военно-воздушные cилы России
The experimental T10-24 was built in 1985. Flight tests took place in 1988. The first prototype was publicly displayed in 1992 at the Farnborough Air Show. Eleven prototypes were built through 1994, with service slated for 1995. Subsequently, the first test flights of an improved Su-35, the Su-37 "Flanker-F", in 1996 and the transfer of existing Su-35 prototypes to this program appeared to suggest the end of the Su-35 development. Instead, the Su-37 aircraft were eventually reconverted to Su-35s. The Su-35 is now in production for the Russian Air Force and was recently presented at the MAKS-2007 International Aviation and Space Salon in August 2007.
The Su-35 shares larger wings and more powerful engines with the naval variant of the Su-27 and later the Su-30, the Su-33 "Flanker-D". Other changes from the Su-27 and Su-30 were canards, a larger nose, the greater use of carbon fibre and aluminium-lithium alloy in the airframe, along with larger, "square-off" tail fins. The new nose holds an improved passive electronically scanned array radar and the aircraft featured many other upgrades to its avionics and electronic systems, including digital fly-by-wire and a rear-looking radar for firing Semi-Active Radar missiles.
A two-dimensional asymmetric thrust vectoring system was tested on the Su-35 and seems to be the basis for the development of the Su-37 "Flanker-F". A new type of 2D thrust vectoring engine, the 117S, has been developed and replaces the current AL-35 or AL-31F. The average output of the Su-35 Radar is 5 kW and a peak output of 20 kW
The Su-37 is a single-seat, all-weather, fighter and ground attack prototype aircraft, derived from the Su-27 'Flanker'. The Su-27 is a Russian fourth generation jet aircraft that has been exported to over 20 nations. The Su-37 test aircraft made its maiden flight in April 1996 from the Zhukovsky flight testing center near Moscow.
The Su-37 includes several updates over the Su-27, including all-weather multi-mode passive electronically scanned array radar with synthetic aperture, terrain avoidance, terrain mapping and a rear facing radar. The airframe includes a percentage of parts made from composites, unlike the all-metal Su-27. Additionally, the Su-37 incorporates the AL-37FU engines equipped with thrust vectoring. The Su-37's nozzles are variable in pitch only and travel plus or minus 15 degrees, but they can be operated differentially to provide a rolling.
The Su-47 is of similar dimensions to previous large Sukhoi fighters, such as the Su-35. To reduce development costs, the Su-47 borrowed the forward fuselage, vertical tails, and landing gear of the Su-27 family. Nonetheless, the aircraft includes reduced radar signature features (including radar absorbent materials), an internal weapons bay, and space set aside for an advanced radar. Though similar in overall concept to the American X-29 research aircraft of the 1980s, the Su-47 is about twice the size and far closer to an actual combat aircraft than the US design.
To solve the problem of wing-twisting, the Su-47 makes use of composite materials carefully tailored to resist twisting while still allowing the wing to bend for improved aerodynamic behavior. Due to its comparatively large wingspan, the Su-47 is to be equipped with folding wings, in order to fit inside Russian hangars. Like its immediate predecessor, the Su-37, the Su-47 is of tandem-triplane layout, with canards ahead of wings and tailplanes. Interestingly, the Su-47 has two tailbooms of unequal length outboard of the exhaust nozzles. The shorter boom, on the left-hand side, houses rear-facing radar, while the longer boom houses a brake parachute.
