Abstract
After the turboshaft engine is installed on the helicopter, it is usually necessary to carry out the flight test of installation loss. The inlet temperature and the inlet pressure of turboshaft engine shall be measured. According to the measurement results and comparison of the performance data of turboshaft engine on the helicopter and the test data received from ground bench, the engine performance changes on the helicopter can be analyzed. In this paper, based on the analysis of the reasons for the loss of engine installation performance, the appropriate test method is selected and the flight test programs are defined, in order to realize the accurate measurement of the engine installation performance loss test, which provides a reference for the test of the engine installation performance loss.
