Active Flow Control for Helicopters
Several active flow control helicopter applications aimed at improving aerodynamic performance have been studied at Onera and are presented in this paper. The distinction between applications for non-rotating or non-lifting parts and for rotating parts is presented.

Active flow control in supersonic nozzles [PDF]
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.
