Mechanical problems in supersonic vehicle environmental engineering

This paper describes some differences between supersonic aircraft powered by liquid ramjet engine and other kinds of aircraft. It introduces the relevant engineering standards at home and abroad, analyzes reasons why standards can’t satisfy engineering requirement, and gives our research results base on the measured data. Some research results about standard satisfy the engineering requirement of quick design. Working process of the supersonic vehicle dynamic excitation source and research progress at home and absroad is reviewed. The current research content, research direction and aircraft environmental adaptability requirement are different. The current research results and research methods can’t satisfy environment adaptability of supersonic aircraft analysis. This paper details the research status of the dynamic analysis method in the model work, and explains the characteristics and difficulties of the model work from the typical examples of ground test, measurement and fault analysis. On the other hand, it explains that the environmental engineering of supersonic aircraft exist lots of problems. Finally, we hope that more researchers will get into in-depth research and together solve the difficulty problems of science and technology.
