Summary: Numerous research studies are conducted about control of flows around bodies in the domain of the fluid mechanics. Fallouts in the industry, to short and means terms, are anticipated because these techniques permit to clear margins that can be used to optimize the operating of a material economically. In the aeronautic domain, the main application concerns aerodynamics and more especially the control of boundary layer and detachment on the body with as small as possible energy magnitude to be injected. In boundary layer phenomena, it is interesting to either delay or even to suppress the laminary-turbulent transition, to consolidate the position of a shock wave and to delay the detachment. In regimes of separated flow, the control is used to reduce the buffeting and to provoke a faster reattachment. Piloting the detachment can be a way to modify the aerodynamic forces operating on the body.
