摘　　要：对转压气机的研制具有重要的军事及国防战略意义,气动设计是研制对转压气机的前提。详细分析对转压气机内部流动特点,探讨对转压气机气动设计思路及方法,根据气动设计指标,在权衡气动和几何设计参数、前后转子设计参数之间的协调匹配性的基础上,设计一种1/2+1对转压气机,并进行三维数值校核。结果表明:前后转子叶片排间设计参数的协调匹配性、后排转子负荷系数和扩散因子等设计参数取值、各叶片排基元叶型参数等对对转压气机性能具有重要影响;所设计的对转压气机满足总体气动性能指标,并且气动性能较高。It is of vital importance to develop counter-rotating compressor for military and national defense,and the aerodynamic design of counter-rotating compressors is a prerequisite for the purpose.A detailed analysis of the in-ternal flow characteristics of the counter-rotating compressor is conducted,and the aerodynamic design ideas and methods of the counter-rotating compressor are explored.On the basis of balancing the aerodynamic and geometric design parameters,as well as the coordination and matching between the front and rear rotor design parameters,a 1/2+1 counter-rotating compressor aerodynamic scheme design is completed and perform three-dimensional nu-merical verification.The results indicate that the coordination and matching of design parameters between the front and rear rotor blade rows,the values of design parameters of the rear rotor load coefficient and diffusion factor,as well as the elementary blade profile parameters of each blade row,have a significant impact on the performance of the compressor.The full three-dimensional numerical simulation results show that the designed counter-rotating compressor meets the overall performance indexes with high aerodynamic performance.
