Study on Crosswind Test Method of High Bypass Ratio Turbofan

The crosswind conditions have an important influence on the performance stability of the high bypass ratio turbofan.In order to carry out the crosswind test of high bypass ratio turbofan,the requirements of crosswind test standard were analyzed.The working principle and debugging calibration method of the crosswind generator were studied.The study of the crosswind test of high bypass ratio turbofan was carried out and the data analysis method of crosswind test was developed.A test device for simulating crosswind environment was developed,and a method for calibrating the wind speed and a program for carrying out the crosswind test were put forward.The results show that the test device can effectively realize the aeroengine crosswind test environment,and the calibration method can obtain the mapping relation between the working state of the crosswind test device and the test wind speed required,and has the important engineering guiding significance.
