Curtiss-Wright VZ-7 Aerial Jeep

Tilting engine exhaust flow is one way to achieve vertical flight, as just discussed; another is to tilt the entire engine, or possibly even the entire aircraft or tilt ducted fans, or even jet engines. Of particular note was the Curtiss-Wright VZ-7 which was developed in the 1950s as a prototype flying jeep, and entered flight test in 1957. The VZ-7 used four 80 inch diameter propellers driven by a 425 HP Turbomeca Artouste II. During flight test it flew as long as 25 minutes at a time, but top speed was under 50 mph. The program was terminated in 1960.
