ABSTRACT:
An aircraft is provided utilizing a spherical balloon filled with buoyant gas such as helium at a pressure substantially greater than atmospheric so that its dimensions are substantially unaffected by changes in atmospheric pressure or temperature. The aircraft may take the form of a self-propelled and self-contained airship, or may be merely a passive device for providing lift and intended to be towed by and controlled from a helicopter. The spherical balloon is mounted on a normally horizontal axle having end portions projecting from opposite sides of the balloon, and includes a rigid load supporting yoke including two arms extending upwardly from a central load supporting structure and each with an upper end suspended from the axle.
