摘 要:The present paper described an experimental investigation of separation control of an Unmanned Aerial Vehicle(UAV)at high wind *** plasma actuator was based on Dielectric Barrier Discharge(DBD)and operated in a steady *** flow over a wing of UAV was performed with smoke flow visualization in theΦ0.75 m low speed wind tunnel to reveal the flow structure over the wing so that the locations of plasma actuators could be optimized.A full model of the UAV was experimentally investigated in theΦ3.2 m low speed wind tunnel using a six-component internal strain gauge *** effects of the key parameters,including the locations of the plasma actuators,the applied voltage amplitude and the operating frequency,were *** whole test model was made of aluminium and acted as a cathode of the *** results showed that the plasma acting on the surface of UAV could obviously suppress the boundary layer separation and reduce the model vibration at the high wind *** was found that the maximum lift coefficient of the UAV was increased by 2.5%and the lift/drag ratio was increased by about 80%at the wind speed of 100 m/*** control mechanism of the plasma actuator at the test configuration was also analyzed.
