The Sukhoi Su 37 Terminator made its debut at the Farnborough International Airshow in 1996. It stole the show with its amazing super manoeuvrability culminating in the 360° cobra or "Kulbit".
Citat:Instead of traditional analogue instruments, the cockpit has four T-form Sextan Avionique (Thales) LCD multi-function displays (MFD). These display air data/navigation, systems status, weapons/systems selection and tactical situation information. The pilot, who is provided with a head-up display (HUD), sits on the K-36DM ejection seat inclined 30° to help counter the effects of high g-forces.The pilot steers with a side-stick and pressure-sensing throttles. The two-grip flying control configuration was designed to prevent the pilot from losing contact with the controls when the aircraft is engaged in fast vectored-thrust maneuvers. Both the fixed throttle and the side-stick controller provide secure points for the pilot to brace his hands.
Citat:The 711 Blue was demonstrated to the press at Zhukovsky in spring 1996, by which time it was re-designated Su-37. Its debut to the general public came in September that year at the Farnborough Airshow, piloted by Sukhoi test pilot Yevgeni Frolov. A big talking point of the show was its performance of the "Super Cobra", when the aircraft pitched up to 180°, literally flying tail first, albeit for only a few seconds; this maneuver evolved into the 360° "Frolov Chakra" somersault.
Cini se da jeste ,jedan izvor navodi podatak o tome
Na MAKS-97 kao i na MAKS-2001 je dakle bio a izgleda i na MAKS-1999 ( snimak ne postoji na YT- kanalu )
Citat:"Wings of Russia" Studio film "Flying Machines - MAKS '99"!
Here they are... together with some unique Russian aircrafts of that time as MiG-1.44, SU-47 (S-37), TU-144LL, Ka-52, SU-33, SU-37.
Izgleda da je 2001 godine imao sasvim nove motore ?
Citat: In 2001, 711 was outfitted with AL-37FU engines and updated fly-by-wire flight control system and avionics. In addition, the hydraulically actuated nozzles of its Lyulka/Saturn AL-37FU (Forsazh Upravlaemoye meaning 'afterburning steerable') engines are steerable -15 to +15 degrees along the vertical plane. Thrust control is fully integrated into the flight control system, requiring no input from the pilot. An emergency system can automatically return the nozzles to level flight in the event of an onboard failure.
Citat:In 1995, the eleventh T10M prototype, T10M-11, was delivered to Sukhoi's experimental workshop to be outfitted with exclusive systems. Built by KnAAPO, its structure has increased carbon-fibre and Al-Li content. Installed was the 2D thrust-vectoring Lyulka AL-31FP, an interim measure pending the availability of the AL-37FU (Forsazh Upravleniye, "afterburner-controlled").The 3D thrust-vectoring Lyulka AL-37FU was still in development. The Al-31FP, in fact, is a hybrid version combining the Al-31F and the vectoring nozzle of the Al-37FU. Being fitted with a 2D vector nozzle, the Al-31FP is only variable in pitch, plus or minus 15°. The engine not only incorporates a new-generation 2D TVC nozzle but also is resistant to engine surge even during inverted and flat spins, giving better reliability and maneuverability even when the angle of attack is 180°.

Citat:AL-31FP
Immediately after the completion of the basic version of AL-31F, the designing of an engine modification with a controlled thrust vector began. The developement of the first experimental engine with an adjustable nozzle was led by general designer V.M. Čepkin, and was already finished in 1988, and passed tests on the airplane T-10-26 in 1989. In 1995, an experimental airplane Su-35 nr. 711 obtained a similar engine. The first flight of Su-35 with the new engine had been performed on 2nd April 1996. During the work on the engine with an axially symmetric vectoring nozzle , two basic issues were dealt with - the creation of the transition between fixed and variable parts of the nozzle where the temperature reaches 2000 ° C and pressures from 5 to 7 atmospheres, and a reliable system of nozzle control. Deflection up to 15 ° in all directions was controlled by the airplane’s system. The emphasis was also place on its long life, which now reaches 500 hours of operation.
Engine was going through gradual development even during test flights of the Su-35. The experience gained then helped when constructing serial AL-31FP engine for airplanes generation 4+ Su-30MKI/MKM/MKA. Now the new engine, radar and avionics are items that increase the competitiveness of the airplane on the world market. Vectored engines allow airplanes to carry out unprecedented maneuvers. The construction documentation for the serial production of AL-31FP was handed to the Ufa-based UMPO, which fulfilled in 2000 and 2001 the obligations that arose from the contract with India in 1996 to supply 40 pieces of Su-30MKI. In 2000, a supplementary contract was signed about licensed production of 140 Su-30MKI in the factories of HAL in India. The contract was worth 3.3 billion USD. Saturn gave the Indian side the technical documentation for the engines,UMPO gave the plant in the city of Karaput all the necessary technical equipment to build engines.
In fulfillment of the contract, the Indian Air Force was supposed to get at least 64 AL-31FP engines for its 32 Su-30MKI. Including spare engines, this amount should have been about 30-50% higher. Until march 2006, there were 16 AL-31FP engines in India. Current (April 2006) Russia's commitment is to manufacture 132 Su-30MKI in India (264 engines), build of 18 Su-30MKM in Malaysia (at least 36 engines) and 28 Su-30MKA in Algeria (56 engines). Therefore, other 356 AL-31FP engines should be made.
Vectored engine nozzle extends to a total length of 4990 mm, thrust is maintained on the value of 12,500 kp.
Development of AL-31FP is closely linked to the engine, which is sometimes referred to by journalists as AL-37FU. Information on this engine are very confused, labeling AL-37FU occurs only in a few sources. I assume there are three ways with this engine. 1) AL-37FU could be an offshoot of the early stages of AL-31FP with an enlarged fan and increased thrust. Development could be in the hands of other companies and engine design after testing has not been further developed. 2) AL-37FU could be a prototype of AL-31FP, morso a technology demonstrator of thrust vector control. The experience gained in its development were then applied in the development of serial AL-31FP. I’m trying to get more information. 3) AL-37FU could be the level between the AL-41F and Item 117.
Опытный двигатель АЛ-37ФУ может развивать максимальную тягу 14500 кгс
Da se podsetimo , AL-31FP je imao maks. potisak na punom forsazu 12500kgs.
Su-37 je dakle prakticno bio leteca laboratorija za motore AL-31FP poput onih Su-30MK-1/MKI a koji su se kasnije serijski proizvodili i ugradjivali u Su-30MKI/MKA/MKM.Ovo oko motora AL-37FU je malo zagonetno a isto tako zbunjuju i podaci uglavnom iz zapadnih izvora o 2D i 3D TVC kako to zovu ( UVT iliti VP ) .U praksi se kod Ruja to zove otklon mlaza po tangazu ( vertikali ) ili tzv `sverakursno` sto ce reci i bocno ( po strani/boku ) tj mogucnost mlaznika da opisuje pun krug prilikom zakretanja/otklanjanja .E sad je tu mali problem kod Suski ako se uzme u obzir ona velika repna greda tako da su tu prisutna veca ogranicenja po otklonu potiska u stranu .
В 1995 году, используя результаты работ с ЛЛ-КС, на один из предсерийных Су-35 (Т-10М-11) установили двигатели АЛ-31ФП с ОВТ, заменили центральную ручку управления самолетом короткоходовой боковой, а традиционные РУДы - тензометрическими (тензоРУДами). Это повысило точность пилотирования и исключило возможность непроизвольного перемещения летчиком органов управления на больших перегрузках. После соответствующих доработок систем управления самолетом и двигателями название машины изменили на Су-37 (название по ОКБ - Су-27М2).
Citat:711 must surely have been the ultimate Flanker, Frolov was superb at the helm especially with the 4 way TVS activated, those displays at Farnborough were something else.
