The VZ-3 was a simple proof-of-concept experimental aircraft using blown flaps to achieve a short or near vertical take-off. It was a high-wing monoplane powered by an Avco Lycoming T53 turboshaft engine located inside the fuselage driving two large-diameter propellers mounted, one on each wing. It had a T-tail and originally a tailwheel fixed landing gear. It had wide-span double retractable trailing-edge flaps, these were extended into the propeller slipstream for takeoff. To enable control while in the hover it had a universally-jointed jet-deflection nozzle at the rear of the aircraft. It was later modified with a nose-wheel landing gear.
