Flying Saucer - Earth-based Examples

Earth-based Examples

The first documented patent for a lenticular flying machine was submitted by Romanian inventor Henri Coanda. He made a functional small scale model which was flown in 1932 and a patent was granted in 1935 At a Symposionum organized by the Romanian Academy in 1967 Coanda said:

"These airplanes we have today are no more than a perfection of a toy made of paper children use to play with. My opinion is we should search for a completely different flying machine, based on other flying principles. I consider the aircraft of the future, that which will take off vertically, fly as usual and land vertically. This flying machine should have no parts in movement. The idea came from the huge power of the cyclons"

Other attempts have been made, with limited success, to produce manned vehicles based on the flying saucer design. While some, such as the Avrocar and M200G Volantor have been produced in limited numbers, most fail to leave the drawing board. The Avrocar, with vertical takeoff and landing, was originally intended to replace both the Jeep and the helicopter in combat situations, but proved to be inadequate for both. In spite of a powerful turbojet, it could not rise more than four or five feet off the ground, i.e., out of ground effect. Thus, the Avrocar could be seen as a prototype for the early generations of hovercraft, lacking only a 'skirt' to make it a truly effective example of the type. Unmanned saucers have had more success; the Sikorsky Cypher is a saucer-like UAV which uses the disc-shaped shroud to protect rotor blades.

Some more advanced flying saucers capable of spaceflight have been proposed, often as black projects by aeronautics companies. The Lenticular Reentry Vehicle was a secret project run by Convair for a saucer device which could carry both astronauts and nuclear weapons into orbit; the nuclear powered system was planned in depth, but is not believed to have ever flown. More exotically, British Rail worked on plans for the British Rail "Space Vehicle" a proposed, saucer-shaped craft based on so far undiscovered technologies such as nuclear fusion and superconductivity, which was supposed to have been able to transport multiple passenger between planets, but never went beyond the patent stage.

There is at least one design that received a US patent in 2005: U.S. Patent 6,960,975 It claims to be "propelled by the pressure of inflationary vacuum state".

Additionally, a professor at the University of Florida has begun work on a Wingless Electromagnetic Air Vehicle (WEAV) for NASA which has received public interest because of its coincidental resemblance to a flying saucer.
