Abstract
1.8 m×1.4 m low speed wind tunnel is a new continuous single return-flow wind tunnel in CARDC. In view of the small size of the wind tunnel test section and it is mainly used for research on fundamental problems, in order to enhance the adaptability of the model support and the model attitude change, reduce the interference for the test section and the influence on the flow field. The mechanism of angle of attack of the wind tunnel model supporting system have used double circular guiding rail and arc gears driving, which can be continuously changed from -30° to 30°; The turntable ground form has been used by sideslip angle of mechanism which can be continuously changed from -360° to 360°; The control system software and hardware have given concrete implementation method. Analysis and the standard model test results show: the system is simple and compact, high rigidity, flexible operation, which model attitude angle can change accurately. It can better meet the needs of routine tests in model attitude angle of tail and abdominal supporting.关键词
