THE PS-90A3 ENGINE IS READY FOR TAKE-OFF!

In January 2011, the PS-90A3 aviation engine was certified.

The PS-90A3 is a modification of the PS-90A2 engine, certified in 2009. The new development from the Perm design department retains all the advantages of the PS-90A2 as a basic engine ľ a high reserve of jet pipe temperature, higher resources on the basic details, and better automatic control systems.

The PS-90A3 is certified in accordance with Chapter 6 of the Airworthiness Codes (Revision 3) since it provides localization of the ventilatorĺs rotor blade stripping. In Perm, they are currently working on how to reduce the bulk of the PS-90A2 fan casing.
