摘要

Russian aero engines maker Salut has completed the climatic bench tests of new Al-31FM2 turbojet engine, which is a further development of the Al-31FM that powers the Sukhoi Su-27 fighter family. These tests have confirmed the static thrust increase of 4,080 Ib. to 32,000 Ib., compared with the basic engine. It also produces 2,200 Ib. more thrust than the AI-31FM1, an earlier upgrade. An improved low-pressure turbine and full-authority digital engine control system are behind the FM2 improvement. Also, the engine has an assigned life of more than 3,000 hr. "The modernization of the AI-31F engine is being conducted without changing its size.
