Abstract: Simulation technology is an important approach to support self-innovation of aero-engine, which demonstrates the R&D level of national advanced equipment. With the advanced simulation tools and methods, the R&D efficiency and quality can be increased by a large margin, while the iterative physical test can be reduced. Hence the time and cost of new engine development can be significantly reduced. In this paper, the development and application status of simulation technology in the dimensions of discipline field, product level, and whole life cycle of aero-engine were discussed. The current problems restricting the development of aero-engine simulation were analyzed subsequently, and the strategy to improve aero-engine simulation ability was proposed.
