    • Abstract
  • 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.
