| 摘 要： | 为提高航空发动机风扇/压气机试验流程控制的合理性和试验结果评定的真实性,在梳理国内航空发动机压缩部件气动性能试验研究现状的基础上,总结提炼出若干重要技术问题,并通过理论分析和部分试验验证,对所涉及的技术问题进行了深入探讨.分析结果表明:风扇气动性能试验和压气机气动性能试验对试验设备排气能力的要求不同;相比升转速录取方式,降转速录取能够优化风扇/压气机的试验流程;可采取不同措施降低测量探针对风扇/压气机试验结果的固有影响;可调导叶/静叶安装角度定位与全行程调节精度是影响变几何多级压气机气动性能试验结果重复性的主要因素.

| Abstract: | 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. |
