摘要
Abstract
Reducing the landing gear resistance is one of the key technologies to improve the aerodynamic performance of aircraft.Taking the multi-point landing gear of a UAV as the research object,the zero-lift resistance coefficient of the front and rear landing gear is compared and analyzed based on the wind tunnel test technology,and the method to improve the resistance characteristics of the landing gear is put forward.The test results show that the zero-lift resistance coefficient of the front landing gear configuration is the largest.Compared with the clean configuration,the zero-lift resistance coefficient increases by 81%,and the maximum lift-drag ratio decreases by 31%.The zero-lift resistance coefficient of the front and rear wheels is obtained by canceling the front/rear wheel as the control group.It is found that the zero-lift resistance coefficient of the front wheel is 0.014 and that of the rear wheel is 0.001.The fairing can be installed to the front landing gear to reduce the resistance.关键词
