摘　　要：调距桨液压系统给螺旋桨螺距的调节提供动力油压,并向桨毂内部输送润滑油。在具体分析调距桨液压系统工作原理的基础上,进行了故障模式影响分析(FMEA),找出导致调距油路失效的所有故障模式、故障原因及故障模式影响,并给出具体的使用补偿措施,以提高系统的可靠性。The hydraulic system of the controllable pitch propeller （CPP） provides hydraulic power to adjust the pitch and sends oil to the inner of the hub. Failure modes and effects analysis of the CPP hydraulic system are conducted based on its working principle analysis to find all the failure modes, failure reasons and failure effects. The compensation measures are given to improve the reliability of the CPP.
