  • Publication number: 20170241397
    Abstract: According to some embodiments, a drum may be submerged in water and extend horizontally along a center axis between a first point on a first side of the drum and a second point on a second side of the drum opposite the first side. Three curved vanes may be attached to the drum such that the vanes, when acted upon by a water flow perpendicular to the axis, are operable to cause rotation about the axis, wherein an edge portion of each vane, located substantially opposite the drum, defines a plane substantially parallel to a plane defined by a surface of the drum located between the edge portion and the axis. An electrical generator coupled to the drum may convert rotational energy produced by the rotation about the axis into electrical energy.

  • Patent number: 5348251
    Abstract: An airship in the form of a self-powered, elongated dirigible which comprises at least three sections connected together by joints. The sections including a front section with propulsion devices and control surfaces, at least one intermediate section designed to carry a payload and a rear section with control surfaces. The joints allow limited articulation between sections under gust conditions and tend to return the sections to aligned condition in calm air. A cover may provide a streamline exterior shape for the airship; alternatively the sections may have rims which mate together when there is no articulation to provide a smooth exterior shape.

  • Patent number: 4366936
    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.

  • Patent number: 4365772
    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.
