Abstract

<p>The characteristics of subsonic nozzles with Fluidic Thrust Vectoring (FTV) were investigated experimentally. FTV nozzles having different cross section area of throat part [Nozzle A,B,C] were designed and built in order to investigate the effect of nozzle contraction ratio and swirl flow on thrust vectoring effectiveness. Deflection angle, pitching moment and thrust of aircraft with the FTV nozzles were obtained though the results of the experiments.</p>
