摘要
参考国外分析CF6和JT9D发动机老化的方法,收集了部分军用涡扇发动机于新机交付、返厂排故和修理、返厂寿命评估时在试车台架录取的试车数据,客观地分析了发动机性能衰减的原因,同时给出了控制的方法。对新发动机的研制以及国外发动机的修理具有一定的参考价值。
The aging analysis method of CF6 and JT9D engine in foreign was referred. The bench test datum of the partial military turbofan engine with new engine delivery, returning to factovy for corrective and repairing and returning to factory for life evaluation were collected.
