L’Avro Canada VZ-9 Avrocar était un avion VTOL développé par Avro Canada dans le cadre d’un projet militaire secret américain mené dans les premières années de la guerre froide. L’Avrocar avait l’intention d’exploiter l’effet Coandă pour fournir une portance et une poussée à partir d’un seul « turborotor » blowing exhaust out the rim of the disk-shaped aircraft. In the air, it would have resembled a flying saucer. Originally designed as a fighter-like aircraft capable of very high speeds and altitudes, the project was repeatedly scaled back over time and the U.S. Air Force eventually abandoned it. Development was then taken up by the U.S. Army for a tactical combat aircraft requirement, a sort of high-performance helicopter. In flight testing, the Avrocar proved to have unresolved thrust and stability problems that limited it to a degraded, low-performance flight envelope; subsequently, the project was cancelled in September 1961.
