Variants

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.

. 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.


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. By replacing the D-30KP on the older

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.

-180 min rated. It is offered in newly built aircraft and is completely interchangeable with the PS-90A, allowing simple upgrades on present airliners. It has the same thrust rating as the PS-90A, 16000 kgf (157 kN, 35,300 lbf) thrust. It is also capable of 18000 kgf (176 kN, 39,600 lbf) thrust. Future American involvement in engine development has been put in doubt after attempts to block sale of PS-90A2 engines to an Iranian customer.


PS-90A-42

This is a version of the PS-90A2 intended for the Beriev A-42 search and rescue aircraft.
