The combination of a Coanda inlet and jet flap diffusion, for the achievement of high performance, low volume, thrust augmentation, has been investigated in a two-dimesnional experiment. The use of jet flap diffusion provides a mechanism for the achievement of large control forces, through the use of variable jet flap angles, or through the application of incremental power to the jet flap. Vectoring of the total thrust force is achievable through the use of the fluidic effect, which can be utilized to detach the flow from one side of the jet flap, by decreasing the plenum pressure of that side relative to the plenum pressure of the other side.
