A circular wing is a disc-shaped wing having the outer planform of a circle. [1] If the aircraft has no fuselage or tail the disc-shaped craft is sometimes described as a flying saucer. If the entire disc rotates it is called a disc wing. Disc-shaped aircraft development dates back to before World War II. A number of disc-shaped aircraft have ...

Military disc-shaped aircraft development dates back to before World War II. A number of disc-shaped aircraft have been proposed over the years, and a few have been built. In 1934, at Miami University (of Ohio), an aircraft called the Nemeth Umbrella Plane (aka Roundwing) was tested.

Mar 1, 2021 · These clever designs have two things in common: they all used a disc-like shape, and they all ultimately failed. A disc-shaped aircraft typically includes a circular wing and a regular...

Apr 3, 2014 · With a fleet of VTOL aircraft, the United States could build underground airports, protected from Soviet bombers. The Avrocar would ascend through a shaft and then zip away at supersonic speeds. The Avrocar’s disc shape and ability to hover bring to mind the flying saucers that we associate with extraterrestrial sources, but the project never ...

Jul 2, 2022 · Unlike Project Y, the Avrocar was a disk-shaped aircraft. Built around a large equilateral triangle as a main structural truss, the disk was 18 feet (5.5 meters) in diameter and 3.5 feet...

Two prototypes were built and resembled flying saucer UFOs. The Avrocar could reach 35 mph in test flights, but the aircraft became increasingly unstable at heights greater than three feet. The...

Oct 8, 2012 · Maneuvering would be accomplished by using small shutters on the edge of the disc (similar to ailerons on a winged aircraft). Power would be provided by jet turbines. According to the cutaway...

Feb 11, 2013 · Avro sold the U.S. on the idea of a supersonic aircraft that could take off vertically and intercept bombers. A disc would provide predictable aerodynamics at high and low speeds.

To sum up, there is no evidence that any 'military disc-shaped aircraft' have ever existed - unless 'disc-shaped' is taken to mean 'having a roundish lifting surface but not actually being circular'. Incidentally, the discussion of the Vought Flapjack's aerodynamics is nonsensical.
