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.
