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 Aleksandrovich 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.
