Avro Project 1794. The Avrocar: When the Pentagon Built a Flying Saucer. The Avrocar started life as Project Y, an Avro internal study from 1952 for a supersonic radial-flow VTOL fighter. The early sketches looked exactly like the standard 1950s science fiction flying saucer because that's what the engineering naturally wanted to be. A central turbine driving a peripheral exhaust ring should, in theory, produce both vertical lift (Coandă effect) and forward thrust (vectored exhaust) from the same rotating mass.
Avro Canada built the craft during the 1950s.The U.S. military funded and later took over the project in 1960 as a secret Cold War initiative.Goal: Designers wanted a runway independent vehicle capable of vertical takeoff and landing (VTOL) to fly low over terrain and fight Soviet forces.
