低速大迎角进气道流场测试风洞试验研究OA

In order to meet the inlet test requirements of a certain type of low-speed and high-angle-of-attack flight test,a compound inlet flow field measurement rake was developed,which integrates steady total pressure,dynamic total pressure and steady static pressure,in order to analyze and evaluate the accuracy of parameters measurement of different measurementrake probes,a full-scale wind tunnel test of measurementrake probes was carried out,and the test data were analyzed,the angle characteristic and velocity characteristic of different rake probe were studied,which provides support for the selection of rake probe for subsequent measurement.
