PRESSURE AND TEMPERATURE DISTORTION TESTING OF A 2-STAGE CENTRIFUGAL-COMPRESSOR

Altitude pressure and temperature inlet distortion testing of the two- stage centrifugal compressor in the T800-LHT-800 engine is described. The test setup and the testing techniques are reviewed and the results of the test are presented. The generation of classical 180 deg patter ns of both pressure and temperature distortion is discussed. Temperatu re distortion was created using a hydrogen burner system while pressur e distortion was created in the classical manner, using screens. Resul ts of both individual and combined temperature and pressure distortion s in both opposed and concurrent patterns are shown.
