摘　　要：航空涡轮发动机的一级涡轮盘是航空发动机中的关键部件。由于发动机涡轮盘转子转速高、温度高,工作环境恶劣,作用在发动机涡轮盘上的涡轮叶片产生的离心力反作用于连接的榫槽,在各种多变载荷、循环载荷作用下,使得涡轮盘容易产生疲劳断裂。通过对某型航空涡轮发动机一级涡轮盘槽底裂纹产生的原理进行分析,结合真实数据和故障造成的影响,提出相应的预防措施来提高航空涡轮发动机的使用性能、可靠性、安全性与经济性。The first stage turbine disc is the key component of aeroengine.Due to the high rotor speed,high temperature and harsh working environment of the turbine disc,the centrifugal force generated by the turbine blades on the engine turbine disc reacts on the connected mortising groove,and the turbine disc is prone to fatigue fracture under various variable loads and cyclic loads.Based on the analysis of the principle of the first stage turbine groove bottom crack of a certain type of aviation turbine engine,combined with the real data and the impact of the fault,the corresponding preventive measures are put forward to improve the performance,reliability,safety and economy of aviation turbine engine.
