Performance of Control Jets on Curved Bodies in Supersonic Cross Flows

What is it about?

A control jet injected into a supersonic cross flow causes a significant disruption of the external flow in the vicinity of injection altering the pressure distribution on the parent body and the effectiveness of the injected jet in producing control forces and moments. In this study, it is shown that while interaction on a flat parent body caused a significant amplification of the jet thrust as well as a significant pitch-up moment about the injection, on curved parent bodies the overall effectiveness is reduced and a pitch-down moment about the injection is generated.
