摘要： A STOL aircraft employs upper surface blowing by mounting jet engines forwardly and above the wings so that the exhaust nozzles of the engines normally open onto the upper airfoil surfaces of the wings. An engine exhaust nozzle is formed by a portion of the upper airfoil surface adjacent to the leading edge of the wing, spaced connecting members extending upwardly from the airfoil, and a channel-shaped panel movably mounted on the connecting members. The panel is movable from a cruise position in which the nozzle directs the engine exhaust stream rearwardly with respect to the longitudinal axis of the engine and a reversing position in which the nozzle directs the exhaust stream upwardly and forwardly with respect to the longitudinal axis of the engine. The movable panel includes a lip door which is nested within the forward portion of the panel during cruise, but which moves forwardly when the panel is in a reversing position to assist in turning the exhaust stream forwardly and to direct the stream outboard with respect to the aircraft. A single powered actuator moves the panel and the lip door from the cruise position to the reversing position.
