航空发动机关键装配技术综述与展望

Aero-engine is a typical high-complexity, high-precision and high-integration mechanical system. However, its requirements of high performance, high safety and long life, as well as the increasing mass production raise the increasing demand of its production quality and efficiency. With the improvement of machining accuracy of parts, the assembly process has gradually become a key influential factor in product quality. Assembly accuracy, quality consistency and efficiency have become important factors restricting product quality and mass production. The aero-engine assembly technology is the core method to solve the above problems, which attracts increasing attention from domestic and foreign scientific research institutions and related enterprises. On the basis of summarizing the typical process and technical system of aero-engine assembly, this paper discusses the main research directions and deficiencies of existing technologies in detail, such as aero-engine assembly mechanism, digital assembly technology, automated assembly equipment, and advanced testing technology. The tendency of high-precision, digitization and intelligence of future aero-engine assembly is expounded.
