摘　　要：通过对某涡轴发动机高原启动过程中出现的转速热悬挂现象进行分析,给出了启动过程热悬挂的原因:采用蓄电池供电,在高高原条件下,发动机启动系统的能力与启动电机并网发电所产生的功率负载不匹配,导致发动机启动失败。通过对比相关试验数据,验证了分析的正确性,可为该型涡轴发动机的改进设计提供参考。Based on the analysis of hot suspension phenomenon in the process of starting of a turbo-shaft engine on plateau,the reason of the hot suspension is ascertained,that is using battery to start the engine under high plateau conditions,the capacity of the engine starting system does not match the power load generated by the starting motor’s connection to the grid,which makes the engine fail to start.The comparison of relevant test data verifies the correctness of the analysis.The study of the paper provides reference for the improved design of the turbo-shaft engine.
