1/2+1对转压气机气动设计研究
Study on aerodynamic design of 1/2+1 counter-rotating compressor
摘要
Abstract
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.关键词
