Abstract: An apparatus is described for producing fluidic jet perturbations for controlling a fluid stream and mix of fluids. The invention is especially applicable to aerodynamic bodies for delaying separation and increasing the maximum angle of attack. The teachings of the invention can easily be converted to produce mechanic or mechanical fluidic effects. The apparatus provides simultaneous perturbations applicable for successive perturbations in the longitudinal direction as well as for segmented requirements. However, the invention may be advantageously used in other applications, such as increasing the angle of divergence in diffusers, controlling and increasing the mixing rate of fluids in the mixing process without adding any mass, and vectoring fluid streams. It can also be applied, among others uses, for a windshield defogger or a vortex generator.
