To develop an intelligent aero-engine

which can adjust its components adaptively based on working conditions

more sensors

actuators

computation processors etc.are needed.Due to their big size and heavy mass

the traditional sensors and actuators will have restrictions when they are used on board considering the compact and limited space inside the aero-engine.This paper reviewed the current statues of MEMS's (micro-electro-mechanical system) application in the environment of intelligent aero-engines.These application fields of MEMS in aero-engine environment included:active flow control

active burning control

health monitoring of structure and lubricating system etc.With the development of MEMS technology

MEMS sensors and actuators will play a more important role in the intelligent engine environment.
