航空发动机风扇/压气机技术发展的若干问题与思考

未来10~20年我国航空发动机科技将迎来千载难逢的发展机遇,必须做好充分准备。以航空发动机核心部件--风扇/压气机气动领域为重点,首先,从设计方法、理论、设计性能指标发展以及气动力学仍存在的疑问角度出发,梳理了其国际发展态势;随后,针对基础研究、创新能力等方面,阐述国内发展现状与存在的问题;最后,分析给出关于风扇/压气机后续发展的方向、思路和重点,力求为我国军民航空发动机风扇/压气机的技术研制思路提供参考。

Some problems and thoughts in the development of aero-engine fan/compressor

In the next 10 to 20 years, China's aero-engine technology will usher in a golden opportunity for development, which we must be fully prepared for. This paper focuses on the aerodynamic field of the aero-engine core components-fan/compressor. Firstly, from the point of design methods, theories and the still existing questions of aerodynamics, we sort out the international development trend. Then against the fundamental research and innovation, etc., we describe the civil development status and problems; finally we analyze the future development, thoughts and emphasis of fan/compressor, which is expected to offer some reference for the research of China's military and civil aero-engine fan/compressor.
