Abstract
An aircraft includes a fuselage and a primary airfoil having a first upper surface. The first upper snake has a recess disposed therein. A conduit is in fluid communication with recess. An ejector is disposed within the recess. The ejector is configured to receive compressed air via the conduit. The ejector is further configured to produce a propulsive efflux stream. A secondary airfoil is coupled to the primary airfoil and has a second upper surface. The ejector is positioned such that the efflux stream flows over the second surface. The second surface is oriented so as to entrain the efflux stream to flow in a direction substantially perpendicular to the first upper surface.
