Numerical simulation of a new-style 2D thrust vectoring nozzle

  • To exclude the inefficiency of existing fluidic thrust vectoring techniques, a new-style nozzle using ejecting mixing effects was proposed, which produced thrust vectoring by making use of the tendency of a fluid jet to be attracted to a nearby surface. The vectoring angles were manually controlled by producing different pressure gradients within the collar, where pumping effects were adjusted by flux limitation. A two dimensional nozzle was designed referring to the current idea. Thrust vectoring control was testified by numerical simulation. The maximum vector angle by flux limitation was 13.3 degree, which can be increased to 20 degree by additional steady jet. The fluidic mechanism of jet vectoring was investigated by numerical simulation, thrust loss and efficiency of the nozzle were discussed, which serves to further experimental study.
