Built for the United States Army with the designation VZ-5 was one of a series of experimental aircraft designed to investigate various aspects and solutions for VTOL aircraft. The VZ-5 was an all-metal high-wing monoplane with a fixed tricycle undercarriage. The fuselage had an open cockpit for one pilot and a rear-mounted high-tailplane. The unusual aspect of the aircraft was that it had one General Electric turboshaft in the rear fuselage driving four propellers, two each mounted in nacelles on the leading edge of each wing. It also had two small four-bladed tail-rotors mounted above the tailplane for control. The wing had conventional trailing edge flaps and ailerons but it also had a section of the wing that could be deflected to act as a full-span flap. For a vertical takeoff two-thirds of the wing chord acted as a flap in the slipstream of the four propellers.
The VZ-5 was first flown tethered on 18 November 1959 but only had limited testing before the project was abandoned. Also see Deflected slipstream for information on the VTOL technology employed with the VZ-5.
