ABSTRACT:
An airship 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 spherical balloon is rotatably 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. The yoke arms carry engines which propel the airship in a forward direction transverse to the axle, and means are provided for rotating the balloon about the axle so that the balloon front surface moves upward relative to the centre of the balloon and provides lift due to the Magnus effect.
