Abstract: An aircraft comprising a hydrogen-containing envelope, a water-collection system for collecting water from the envelope, an electrolyzer to convert the water collected using the water-collection system into hydrogen, and a hydrogen-replenishment system for replenishing the envelope with hydrogen generated using the electrolyzer. In one embodiment, generated hydrogen is also supplied to a hydrogen-fuelled propulsion system for propulsion of the aircraft.

Abstract: The invention relates to a mechanism to control the pitch and/or roll and/or center of gravity of a vehicle. The first embodiment is a track-based mass transfer system in which pathways are positioned along or radially terminate at a central horizontal plane of the vehicle to move one or more mass transfer devices to a desired location to control the pitch and/or roll and/or center of gravity of the vehicle. A second embodiment is a fluid mass distribution system in which one or more conduits selectively distribute a fluid to one or more tanks positioned near a central horizontal plane of the vehicle to control the pitch and/or roll and/or center of gravity of the vehicle.

Abstract: An airship ballast system includes an engine driven propeller and a cooling tube that is positioned coplanar with the propeller and outside its tip path. One end of the cooling tube is connected to receive exhaust gases from the engine while the other end is connected to a ballast tank. In operation, exhaust gases from the engine are cooled as they transit the cooling tube, and water condensed from the cooled exhaust gases is pumped to the ballast tank to maintain a ballast for the airship.

Abstract: A lighter than air aircraft has a non-jettisonable ballast comprised of a liquefied lighter than air gas contained within an insulated container. The liquefied gas is vaporized and released into the lift compartment of the aircraft which is at least partially filled with a lifting gas. A heat exchanger, separate from the means delivering the vaporized gas to the lift compartment, increases the temperature of the vaporized gas prior to entry of the vaporized gas into the lift compartment, wherein the vaporized gas becomes mixed together with lifting gas and whereby damage to the compartment by excessive cooling is minimized.

Abstract: A flying machine (L.T.A.-H.T.A. Hybrid) connected through the fuselage . . . using a two-point-lift system wherein the lifts are static and dynamic . . . separately and simultaneously. The static lift is supplied by an aerostat (#36) while the dynamic lift is supplied by an atmospheric deflector (#48) . . . This system, by the clever use of 180 degrees pivotable pusher (blower) engine (#1), being and becoming capable of:1. S. T. O. L. and/or V.T.O.L.2. Rearward FlightA two-point-lift system, as stated in the preferred embodiment (technical description), employing L. T. A. and H. T. A. method (separately and simultaneously) to be allowed development on a non-exclusive basis (excluding Balopod). The process levels the device by coordinating static lift, thrust, and dynamic lift.

Abstract: A system for automatically controlling the buoyancy of a lighter-than-air craft by condensing water ballast from engine exhaust gases.
