Abstract: A high lift vertical takeoff and landing aircraft has first and second fuselages connected by a central airfoil. Jet engines at the leading edge of the airfoil expel propulsive streams simultaneously over top and bottom surfaces of the foil. Extendable flaps are utilized at a trailing edge of the airfoil with a horizontal control blade being attached to the leading edge of the foil. The control blade is within the jet's propulsive stream to permit proportioning of the stream above and below the airfoil.An extendable augmenter wing is attached between the fuselages aft and above the main airfoil to permit airflow in this region to be directed downwardly, accelerating the flow and providing additional lift.The main airfoil is positioned so that the fuselage walls extend above and below the foil. Lateral flow of the main engine exhaust is restrained by these walls. Above the wing the walls and airfoil create a venturi to speed airflow and decrease pressure.

Abstract: The invention is an improvement to the female portion of a quick disconnect lectrical connector so that said portion can be easily disassembled for refurbishment. The female portion of the quick disconnect is of the type having concentric sleeves which are slidable with respect to one another. The forward ends of the sleeves are adapted to receive a male portion of the mating electrical connector, and the rearward end of one of the sleeves is connected to an elongated element, such as an electrical cable. An annular space is provided at the rearward end portions of an inner and outer adjacent pair of the sleeves, and a compression spring within the annular space is utilized for urging the adjacent sleeves longitudinally apart with respect to one another. The improvement includes a device located within a rear portion of the annular space and releasably connected to the inner adjacent sleeve for stopping rearward movement of the compression spring.
