ABSTRACT:
Various modifications are disclosed of the composite aircraft, which is the subject of U.S. Pat. No. 3,856,236 by this same inventor. The control console is supported from the center of the upper rotating balloon sphere instead of its south pole to reduce the periodic motion of the console about its point of attachment to the sphere. The console is supported from the center of an inner framework through a tapered indentation in the bottom of the sphere. A lift command control system determines the angle of attack of each wing about the periphery of the sphere to provide the force required to generate movement of the sphere in a preselected direction. If the wing experiences a gust, the force reaction compels the wing to seek a different angle of attack to keep the new force in balance with the command force exerted by the control on the wing to automatically provide gust control. A pneumatic lift command control system is illustrated. The altitude of the aircraft is controlled by maintaining the gas pressure at constant temperature by heat, such as obtained from the engine. Other variations for reducing drag include: boundary layer control of air pressure about the sphere to overcome the Magnus effect enclosing the sphere in an envelope, which does not rotate relative to the air, flattening the sphere and driving it by auxiliary engines instead of tilting it or by applying cone-shaped sections to one hemisphere and translating a substantially horizontal position.
