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.
Design features
It incorporates many firsts in a one-of-a-kind Russian engine with advanced technology features such as
High-bypass turbofan design for economy
Integrated exhaust with exhaust mixer for good efficiency
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 Tu-204-100 and Tupolev Tu-214. For the first time, it allowed Russian airliners to achieve similar performance and economy to their western counterparts.[1]
PS-90A-76
This variant is a modification of the basic PS-90A engine. It is rated nominally up to 14,500 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 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.
PS-90A1
This variant is also a modification of the basic PS-90A engine. It was certified in 2007 and is offered as an option on the IL-96-400T aircraft.[3]
