Status,Challenges and Perspectives of Aero-Engine Simulation Technology

仿真技术是支撑航空发动机自主研发的重要手段,体现了一个国家的高端装备研发水平,可大幅提高航空发动机的研发效率和质量,减少实物试验反复,缩短研制周期,降低研制成本。本文论述了仿真技术在航空发动机学科领域维、产品层次维和全生命周期维三个方面的发展与应用现状,分析了航空发动机仿真技术发展存在的问题,提出了提升仿真能力的战略措施。

Simulation technology is an important approach to support selfinnovation of aeroengine, which demonstrates the R＆D level of national advanced equipment. With the advanced simulation tools and meth ods, 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 de velopment 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 aeroen gine simulation were analyzed subsequently, and the strategy to improve aeroengine simulation ability was pro posed.
