In order to improve the rationality of experimental process control and the authenticity of experimental results assessment of aero-engine fan/compressor

several important technology problems were summarized by analyzing the aerodynamic performance experimental research situation of the domestic aero-engine compression components. Through theoretical analysis and partial experimental validation

these technology problems were discussed in depth. The analysis results show that the requirements of experimental facility exhaust system ability are different for fan aerodynamic performance experiment and compressor aerodynamic performance experiment; compared with the method of rising rotating speed collection

decreasing rotating speed collection can optimize the fan/compressor experimental process; the inherent effects of measuring probes on fan/compressor experimental results can be reduced through different methods; the stagger angle positioning and full stroke adjustment accuracy of the adjustable guide vane/stator vane are the main influential factors to the repeatability of aerodynamic performance experimental results of variable geometry multistage compressors.
