PS-90A-42 turbojet aero-engine

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.
