[0002] The high-altitude simulation test of aero-engine is an important means of aero-engine design verification and an insurmountable important link in the development process. The traditional high-altitude simulation test mode requires a lot of equipment, high test risks, and the test subjects are complicated and costly. In the future, The difficulty of engine development has increased significantly, and the test technology is bound to face new developments

At present, physical tests are still used in China to evaluate the performance of aero-engines. Simulation technology has only been widely used in the process of engine design, and it is still in its infancy in the field of high-altitude simulation tests, which cannot meet the development needs of new test technologies.

[0003] At present, the aero-engine test technology system is not perfect, and there is a considerable gap compared with foreign countries. In particular, the real-time approaches, methods, and technical solutions adopted for virtual test technology are still unclear. , prototype construction, application verification and other aspects of research is very lacking
