PS-90A-42 turbojet aero-engine

PS-90A2 is one of the PS-90A modifications.

It is a twin-spool, bypass turbofan with fan and core airflows mixing and high level of commonality.

It has been designed for A-42 search-and-rescue amphibian aircraft.











The specific design features are as follows:

  •  the engine is not equipped with a thrust reverse;
  •  the pylon is in lower position and, therefore, the routing of pipes and wiring as well as interfaces of some systems with an aircraft have been modified;
  •  engine control programs have been updated for higher primary parameters;
  •  corrosion resistance is higher.
