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。 Aeroengine technology-intensive and difficult, and its manufacturing level is an important symbol of the level of industrial technology. This paper briefly describes the structure and characteristics of the aero-turbine engine. Based on the basic theories of thermodynamics and fluid dynamics, this paper explains the structural evolution of several aero-turbine engines and introduces the key technologies of the aero-turbine engine. Crystal nickel-based alloy blades, and finally gives an overview of the development of China’s aviation engine business.
