Curtiss-Wright VZ-7

The Aerophysics design sat two in tandem between four ducted fan rotors and could also be armed with machine-guns or recoil-less rifles.

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).

[citation needed] The aircraft performed well during tests but, not being able to meet the Army's standards, 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 Novosel.
