The Aviadvigatel PS-90 is a Russian high-bypass commercial turbofan rated at 16000 kgf (157 kN, 35,300 lbf) thrust.

It is made by the Russian aircraft engine company Aviadvigatel, which is the successor of the Soviet Soloviev Design Bureau.

With the advent of new generation of Soviet airliners, Aviadvigatel developed the PS-90 to satisfy the demands of economy, performance and exhaust emissions.

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 Rolls-Royce RB211-535E4 engine (which is also offered on the Tu-204), and the fuel consumption is 8.2% less than it.

Fuel efficiency, and performance will be markedly improved and noise pollution reduced to comply with the new strict requirements.

It is offered in newly built aircraft and is completely interchangeable with the PS-90A, allowing simple upgrades on present airliners.
