ABSTRACT:
An aircraft capable of flying at very low velocities utilizing a wing envelope of an aerodynamic configuration having cells filled with a lighter-than-air gas. In one embodiment the buoyancy of the wing is slightly less than the total weight of the aircraft wherein forward movement is required to provide lift. In another embodiment the buoyancy is greater than the aircraft weight wherein forward motion is required to produce universal control without the release of gas or ballast. The wing envelope is formed of a plurality of trussed members radially extending from an axis producing a plurality of cells covered by a lightweight high strength skin material, the aircraft being characterized by high strength, economy and efficiency of construction and efficiency of lift at low speeds.
