摘　　要：涡轴发动机是现代直升机的动力来源,由于功率大、转速高、工况恶劣,极易发生各种故障。本文通过深入的研究涡轴发动机典型故障模式,分析故障原因、故障部位,为涡轴发动机故障诊断、维修保养提供理论参考。The turboshaft engine is the power source of modern helicopters. Because of its high power, high speed and bad working conditions, it is easy to have various faults. In this paper, the typical fault modes of turboshaft engines are studied, and the causes and locations of the faults are analyzed to provide theoretical reference for fault diagnosis, maintenance and repair of turboshaft engines.
