摘　　要：为获取压缩部件比在常规大气进气条件下开展部件试验更加真实的试验结果,介绍了2种模拟真实进口条件的压缩部件试验设备及方法,并对不同试验方法获取的试验结果进行了对比。结果表明:采用进口加温加压供气的方式可在部件试验器上模拟整机环境下高压压气机进口条件;采用低温供气节流的方式可在部件试验器上模拟风扇/增压级部件高空低温低压条件;模拟真实进口条件试验可开展部件级的真实工况考核试验以及雷诺数对压缩部件影响等研究试验;压缩部件模拟真实进口条件下的试验结果与整机或高空台试验结果存在一定差异,这与测试布局,试验件加工、装配以及各部件匹配影响等因素有关。To obtain more realistic test results for compression components compared to conventional atmospheric inlet conditions,two kinds of compression component test equipment and methods simulating real inlet conditions were introduced,and the test results obtained by different test methods were compared.The results show that the use of inlet heating and gas supply pressurization can simulate the inlet conditions of high-pressure compressors in the engine environment on the component tester,and the use of lowtemperature gas supply throttling can simulate the high-altitude,low-temperature,and low-pressure conditions of fan/booster stage components on the component tester.The simulation of real inlet condition test can carry out the real working condition assessment tests on the component level and research experiments on the influence of Reynolds number on compression components.There is a certain difference between the test results of the compressed component simulation under real inlet conditions and that of the whole engine or high-altitude simulation test,which is related to factors such as test layout,test piece processing,assembly,and the influence of component matching.
