Description: The AL-31 is a family of turbofan engines developed to power the Su-27/32 multi-role fighter aircraft family. They were developed by the former Soviet Union and currently are manufactured by NPO Saturn. They deliver between 27,000- and 32,000 pounds of thrust and are one of the keys for Su-27 outstanding performance. Besides growing in thrust, AL-31 have incorporated other advancements such as Thrust Vectoring Control (TVC) providing Super Maneuverability to Su-27/32 aircraft.

The NPO Saturn AL-31F model was selected to power the Su-27 and Su-27UB aircraft and is rated at 27,500 pounds of thrust. The same engine was also provided to the Su-33 and Su-30MK aircraft. Some reports suggested that Russia was offering AL-31 to Iran to re-engine its F-14 Tomcat air defense fighters in the late 1990s. It is also known that AL-31FN is an engine option for some Chinese indigenous fighter aircraft programs such as J-10/F-10 and FBC-1. In early February 2009, Rosoboronexport stated that had signed up a new contract for the supply of more than 100 engines to power the People's Liberation Army Air Force (PLAAF) J-10 jet.
