PS-90A-76 Aircraft Engine
The PS-90A-76 aero engine (PS - Pavel Soloviev) is a modification of the PS-90A turbofan. It extends service life of the large fleet of the IL-76 transport airplanes and raises their efficiency by installation of the PS-90A-76 engine instead of the D-30KP. It allowed to build a new modification of the IL-76 airplane - the IL-76MF military freight aircraft which meets modern requirements.
It is a high-bypass-ratio, two-shaft turbofan, with mixed flow and a thrust reverser in a fan duct and noise absorbing system.
Il-76The aero engine is intended to power IL-76 cargo aircraft and its modifications.
The engine was certified in 2003.
In 2004 Perm Engine Company launched the serial production of the engine.
PS-90A-76 engines are currently in service at three (3) Airlines.
