ABSTRACT:
A lighter-than-air saucer or disc-shaped non-rigid airship is disclosed. A saucer-shaped flexible envelope is provided within which an annular pressurized tube is positioned so as to maintain the flexible envelope in a saucer shape when inflated. Walls within the envelope from a central chamber and a plurality of outer chambers symmetrically disposed around the central chamber. Typically a load such as a gondola is suspended beneath the central chamber. To maintain level horizontal flight stability, differential forces are developed by preferably providing the central chamber with heated air and the outer chambers with a lighter-than-air gas such as helium providing greater lift than the central chamber. Propulsion units are preferably arranged at opposite peripheral side edges of the envelope and maneuvering of the saucer-shaped airship is accomplished by rotating the airship.
