Abstract
A fluid flow control device controllably maintains attached flow in the region of a body having a contour of rapid curvature utilizing tangential fluid discharge slots, positioned just upstream from the separation line, which issue a thin jet sheet to energize the boundary layer and entrain the surrounding flow. When applied to the aft fuselage of an aircraft, the device reduces separation and vortex drag at cruise and provides control forces and moments during low speed operation of the aircraft.
