PS-90A-76 engine (PS - Pavel Soloviev) is a modification of PS-90A turbofan bypass engine. 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 cargo aircraft which meets modern requirements.
Turbofan, bypass, two-shaft, mixed flow, with a thrust reverser in a fan duct and noise absorbing system.
The engine was certified in 2003.
