Abstract: A turbofan engine thrust reverser comprising a plurality of pivotally mounted duct members forming an integral part of the engine cowl. These members redirect the exhaust air of the fan forward and outward at such velocity and angle that the suction of the engine inlet is insufficient to cause reingestion.

Abstract: A short takeoff and landing (STOL) aircraft employing turbofan engines and a wing and flap arrangement to provide propulsive lift, a high lift capability, and a steeper landing approach flight path. Improvements in these characteristics are achieved by a particular positioning of the engine fan and primary exhaust efflux flow relative to the wing and by locating the flaps for operation in consort with the engine-derived gaseous flow and the wing.
