Inlet Distortion Test with Gas Turbine Engine in the Altitude Engine Test Facility

Abstract

In this study, three types of inlet distortion simulating device - screen, blockage and delta wing type - were developed and preliminary testing was carried out with dummy engine in the Altitude Engine Test Facility(AETF) of Korea Aerospace Research Institute(KARI) in order to evaluate operational capability of simulating device. According to preliminary test result, the inlet distortion device could be used in simulating various inlet distortion cases. Based on preliminary distortion test results, inlet distortion test with real gar-turbine engine was performed using blockage and delta wing type inlet distortion devices. During the test, the deterioration of overall performance and stability was observed.
