Active flow control in supersonic nozzles [PDF]
AIP Conference Proceedings, 2018 Active flow control in supersonic nozzle mainly concerns Fluidic Thrust Vectoring (FTV) strategies. Thrust Vectoring in fixed symmetric nozzles can be obtained by generating a local perturbation at wall causing flow separations, asymmetric pressure distributions and therefore, the vectoring of the primary jet thrust. The control action can be steady, e.
