Abstract
The key manufacturing technology of aero-engine is an important index for the future development of aero-engine industry in China. The traditional manufacturing process and production mode can't meet the requirements of high precision, high quality, high efficiency and high reliability of aero-engine. The following three-axis, four-axis, five-axis digital processing is an important foundation for the future development of China aero-engine manufacturing industry. Aero-engine is the most important component of aircraft power supply system, and has experienced the development process of DC engine, brush synchronous engine and three-stage brushless synchronous engine. On the basis of analyzing the performance and characteristics of various engines, this paper analyzes the development direction of new civil and military aero-engines.
