发动机是所有航空装备的“心脏”.对飞机而言,发动机决定着其飞行速度、机动性、航程、有效载重、可靠性、经济性和环境适应能力.航空发动机的设计和制造是多学科交叉、多部门参与、综合性极强的复杂系统工程,是当今尖端的、难度大的高科技综合体现,是使用要求与条件最为严格与苛刻的动力装置.
涡轮是发动机的重要组成部分,它不仅要将高温燃气中的部分热能和压力能转换成机械能,还要带动压气机和部分附件工作.涡轮叶片是航空发动机涡轮最重要的部件之一,是高温、高负荷、结构复杂的典型热端构件,它的设计制造性能和可靠性直接关系到整台发动机的性能水平耐久性和寿命.为了提高发动机的推重比,叶片设计时常采用比强度高的新材料；采用先进复杂的冷却结构及工艺；降低工作裕度等措施实现.因此,研究涡轮叶片失效问题对他提高发动机工作安全及正确评估叶片的损伤形式和损伤程度有重要意义.

The engine is the "heart" of all aviation equipment.For the aircrafts,the engine determines its flight speed,maneuverability,range,payload,reliability,economy and environmental adaptability.The design and manufacture of aircraft engine is a multi-disciplinary,multi-sectoral participation,highly complex systematic engineering,manifestation of today's cutting-edge,difficult high technologies,and power device with the most stringent and harsh requirements on its use and conditions.
The turbine is an important part of the engine,which not only converts the heat and pressure of high-temperature gas into mechanical energy,but also drives the compressor and some accessories.The blades are one of the most important parts of the turbine,a typical hot end component with high temperature,high load,the complex structure,whose design and manufacturing performance and reliability is directly related to the durability and life of the engine performance.In order to increase engine’s thrust to weight ratio,blade design is often realized by using high strength materials,sophisticated cooling structure and process and reducing the working margin and other measures.Therefore,the study of turbine blade failure is very important to improve engine safety at work and correct assessment of leaf damage in the form and degree of the injury.
