Dual point active flow control system for controlling air vehicle attitude during transonic flight

摘要

An air vehicle having a fuselage and two wings extending laterally therefrom and having a first surface between leading and trailing edges and an opposite second surface. The vehicle includes adjacent upstream and downstream orifices positioned on at least one first surface. Each upstream orifice is closer to the leading edge than the downstream orifice. Each second surface is substantially free of orifices. The vehicle includes an actuator within each wing having orifices. Each actuator is connected to corresponding upstream and downstream orifices for creating a negative pressure differential at the upstream orifice and a positive pressure differential at the downstream orifice so air is drawn into the upstream orifice and air is pushed away form the downstream orifice. The orifice is configured so air is drawn into and directed out of the upstream and downstream orifices, respectively, at an angle of about 90% with respect to the first surface.
