Adaptive Engine Technology in Military Aviation

Abstract

From the sixties of the last century, both in civil and military aviation, the pure turbojet engines were replaced by the two-stream engines. The low bypass ratio engines appeared first, and then the bypass ratio steadily increased in commercial aircraft engines. Nowadays, low bypass ratio engines are typically the power sources of multi-role combat aircrafts. The design of the engine itself has actually not changed for decades. In comparison, adaptive engine technology can represent a new level and a real leap in quality. In this paper, I present this development process and the expected benefits.
