摘　　要：航空发动机的技术含量密集而难度高,其制造水平是一个国家工业技术水平的重要标志。航空动力主要使用燃气涡轮发动机,本文简要描述了航空涡轮发动机的结构类型和特性,运用热力学和流体力学的基础理论解释了几种航空涡轮发动机的结构演化,并介绍了航空涡轮发动机的关键技术单晶镍基合金叶片,最后给出了我国航空发动机事业的发展概况。The manufacturing level of aero turbine engine, as a high difficult and intensive industry technology, is the symbol of the country＇s level of industrial technology. Considering that aircraft is used to be driven by gas turbine engine, this paper introduces briefly the structure types and characteristics of gas turbine engines. The design idea of the structure evolution of several types of gas turbine engines is described by using thermodynamics and fluid mechanics law. Besides of discussing Nickel-based single crystal turbine blade the core technology of the aviation gas turbine engine, the paper introduces the development of China＇s aero engine industry.
