Test method of the real inlet conditions simulation for compression component
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 low-temperature 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.
