The fourth generation aero-engine AL-3 1F is called "uncle" by many "nonsense" military fans. It is a turbofan engine with afterburner developed and produced in Russia. In fact, from this type of engine, it can be found that there is no problem for a mature engine to continue to use for more than 20 years. Because the AL-3 1F engine has been produced for more than 20 years.
In the 1990s, Salute Company (with a strange name) provided the first batch of AL-3 1F for the former Soviet Air Force, and installed it on Su -27 fighters with double release boards. Although Salute has carried out product quality tracking, preventive maintenance and regular maintenance, the maintenance measures cannot guarantee the permanent use of the engine.
