摘要
现代航空发动机的高速发展,要求发动机在宽广的飞行范围内获得高的性能.由于全权限数字式发动机控制系统(FADEC)与传统的机械液压控制系统相比具有功能强、性能好、控制精度高、重量轻和体积小等优点,而得到快速发展.在我国,要实现航空发动机控制系统由传统的机械液压式到数字式的转变,是一个革命性的转变,必须在现役飞机和发动机上进行验证,以便集中暴露自行设计的FADEC自身的问题。
The full authority digital electronic control ( FADEC ) is a new technology of the modern aero-engine . As it has the merits of the better function , performance , control precision and the light weight by comparision with the machine hydraulic control system it is wide used for the aero-engine . In order to find faults in the FADEC the demonstrating test of the FADEC should be made. The paper presents the four phases of the demonstrating test and the roles, modes, several carefull problems of the fling test about the FADEC.
