Avrocar VZ-9-AW

Canada's circular winged 3-jet powered saucer prototype. Avro Canada's initial secret project was intended to use the Coanda Effect to provide lift and thrust from a single turbo rotor blowing exhaust out of the rim of the disk-shaped aircraft. Designed by the late John Frost in the early 1950s for a vertical takeoff and landing (VTOL) flying machine. Written by David Myhra, PhD and Published by Robert at RCW Technology & Ebook Publishing
