The Curtiss-Wright VZ-7 (also known as the VZ-7AP[1]) was a VTOL quadrotor helicopter aircraft designed by the Curtiss-Wright company for the US Army. Like the Chrysler VZ-6 and the VZ-8 Airgeep it was to be a "flying jeep".

Design and development

The Aerophysics Development Corporation, a subsidiary of Curtiss-Wright, designed an "Aerial Platform" for a US Army Transport and Research Command "Flying Jeep" design competition. The Aerophysics design sat two in tandem between four ducted fan rotors and could also be armed with machine-guns or recoil-less rifles.[2]

To prove the design concept the US Army ordered two prototypes of a smaller single-seat demonstrator, the VZ-7, which were delivered to the US Army in mid-1958. The VZ-7 had a fuselage with the pilot's seat, fuel tanks and flight controls. On both sides of the fuselage the four propeller/rotors were attached, unshrouded (the aircraft did originally have shrouds, but these were later removed). The VZ-7 was controlled by changing the thrust of each propeller and was maneuverable and easy to fly.^{[citation needed]}

Operational history

The aircraft performed well during tests, but was not able to meet the Army's standards, therefore it was retired and returned to the manufacturer in 1960.

One VZ-7 is part of the United States Army Aviation Museum aircraft collection at Fort Rucker. However, it is not currently on public display due to space restrictions.[3][4]

Die Curtiss-Wright VZ-7 war ein experimentelles VTOL-Flugzeug des US-amerikanischen Herstellers Curtiss-Wright Corporation aus den 1950er Jahren. Wegen der konstruktiven Auslegung als Quadrocopter kann das Luftfahrzeug auch den Hubschraubern zugeordnet werden. Wie die VZ-6 und VZ-8 wurde die VZ-7 im Rahmen des Flying-Jeep-Wettbewerbs entwickelt.
