The invention discloses a method for eliminating jitter faults of an adjustable nozzle on an aircraft in situ. When the jitter faults of the adjustable nozzle in a stress application state occur in the working process of an aero-engine, the faults are eliminated by adjusting the lengths of a pull rod and a stop rod in situ and changing the outlet diameters of the nozzle and a throat. The problems of low troubleshooting efficiency and low success rate due to the fact that an existing adjustable nozzle shakes are solved.
本发明公开了一种飞机上原位排除可调喷口抖动故障的方法,当航空发动机工作过程中发生加力状态可调喷口抖动故障时通过原位调整拉杆、止动杆长度,改变喷口、喉道出口直径来进行故障排除。解决现有可调喷口抖动出现故障排障效率低成功率低的问题。
