Aviadvigatel PS-90

The Aviadvigatel PS-90 is a Russian high-bypass commercial turbofan rated at 16000 kgf (157 kN, 35,300 lbf) thrust. It powers Russian airliners such as the Ilyushin Il-96 and the Tupolev Tu-204/Tu-214 series and transport aircraft such as the Ilyushin Il-76. It is made by the Russian aircraft engine company Aviadvigatel, which is the successor of the Soviet Soloviev Design Bureau. "PS" are the initials of Pavel Soloviev (Russian: Павел Алеќсандрович Соловьёв).

With the advent of new generation of Russian airliners, Aviadvigatel developed the PS-90 to satisfy the demands of economy, performance and exhaust emissions. It represented a huge advance over previous generations of 1960s era Soviet engines. The PS-90 is almost double the efficiency of those engines and is reasonably competitive to western engines of the 1980s such as the Pratt & Whitney PW2000.

It incorporates many firsts in a Russian engine with advanced technology features such as

It was first certified in 1992 and has been in service since.

There are several variants: the basic PS-90A, the PS-90A-76, and the improved PS-90A versions. The latter include the PS-90A1, PS-90A2, PS-90A-42 and the PS-90A3 engines.

The PS-90A engine is the initial variant and is standard equipment for Ilyushin Il-96-300, Tupolev-204-100 and the Tupolev-214. For the first time it allowed Russian airliners to achieve similar performance and economy to their western counterparts. PS-90A is rated nominally at 16000 kgf (157 kN, 35,300 lbf) thrust, 13.3% less than the original Rolls-Royce RB211-535E4 engine (which is also offered on the Tu-204), and the fuel consumption is 8.2% less than it.[1]

This variant is a modification of the basic PS-90A engine. It is rated nominally up to 145,00 kgf (142 kN, 32,000 lbf) take-off thrust.[2]

By replacing the D-30KP on the older Il-76, the service life of the aircraft can be extended. Fuel efficiency, and performance will be markedly improved and noise pollution reduced to the comply with the new strict requirements. With the large fleet of both civil and military Il-76 aircraft still in operation, a potentially large market exists for engine replacement. An example of such a modified version is the Il-76MD-90. The PS-90A-76 is the standard on the newly built, modernized versions of the Il-76, such as the Il-76MD-90A and the Il-76MF.
