摘　　要：通过静态推力实验,研究了襟翼形状对机翼上表面喷流偏转的影响。在此基础上,通过涡流发生器对喷流偏转进行被动控制,研究了涡流发生器安装位置、安装角和涡流发生器高度对喷流偏转性能的影响。结果表明:喷流偏角在襟翼偏角为30°时达到最大值,并随襟翼半径增大而增大;使用涡流发生器有助于促进喷流附着、增大喷流偏角;安装角和涡流发生器高度是影响喷流偏转性能的关键参数。The effect of flap shape on jet deflection on the upper surface of the wing is studied by the static thrust experiment.On this basis,the jet deflection is passively controlled by the vortex generator,and the effects of the installation position,installation angle and height of the vortex generator on the jet deflection performance are studied.The results show that the jet deflection angle reaches the maximum when the flap deflection angle is 30°and increases with the increase of the flap radius.The use of vortex generators helps to promote the jet adhesion and to increase the jet deflection angle.Its height and installation angle are the key parameters that affect the deflection performance of the jet.
