Abstract:
An aircraft comprising a hydrogen-containing envelope, a water-collection system for collecting water from the envelope, an electrolyser 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 electrolyser. In one embodiment, generated hydrogen is also supplied to a hydrogen-fuelled propulsion system for propulsion of the aircraft.
Abstract:
An airship is provided. The airship includes a hull configured to contain a gas, at least one propulsion assembly coupled to the hull and including a propulsion device, and at least one aerodynamic component including a plurality of fairing structures including one or more slats, wherein the at least one aerodynamic component is associated with the hull and is configured to direct airflow around the airship.
Abstract:
An improved airship having a plurality of resilient gasbags & gas containers, a straight fuselage tubular hull with an inner air passageway & propulsion means located therein, connecting air inlet & outlet funnels fore & aft, with air deflector cones axially positioned therein, and a plurality of bifurcated winged air control surfaces axially affixed vertically & horizontally across the air inlet & outlet funnels fore & aft; further, a plurality of vectored air passageways & mechanisms, and propulsion, reverse, & directional rocket thrusters, positioned fore & aft, top, bottom, port & starboard; thereby providing improved speed, maneuverability, efficiency, adverse weather capability, reduced forward air resistance, & rearward drag; furthermore space, outer & inner atmosphere ingress & egress.
Abstract:
A system comprising an unmanned aerial vehicle (UAV) having wing elements and tail elements configured to roll to angularly orient the UAV by rolling so as to align a longitudinal plane of the UAV, in its late terminal phase, with a target. A method of UAV body re-orientation comprising: (a) determining by a processor a boresight angle error correction value bases on distance between a target point and a boresight point of a body-fixed frame; and (b) effecting a UAV maneuver comprising an angular role rate component translating the target point to a re-oriented target point in the body-fixed frame, to maintain the offset angle via the offset angle correction value.
Abstract:
An air vehicle includes a bag skirt extendable along a portion of a hull of the air vehicle. The bag skirt is inflatable to provide an air cushion during touchdown and deflatable during flight of the air vehicle. The air vehicle also includes a cover roller adjacent the bag skirt, and a cover portion coupled to the cover roller. The cover roller is operable between exposed position and unexposed positions to expose and hide the bag skirt with the cover portion. The cover roller includes an extensible shaft and a pad securely wrapped around the extensible shaft. The extensible shaft is capable of being rotated along a shaft axis. One end of the extensible shaft is pivotally coupled to the hull by an anchor. A circumference of the cover roller is configured as a function of a distance between the exposed and the unexposed positions.
Abstract:
An airship comprising a hull configured to be inflated with a first gas; a ballonet in the hull, the ballonet configured to be inflated with a second gas that is heavier than the first gas; a fan configured to draw the second gas into the ballonet; an inflatable landing system; a duct configured in the ballonet to allow access to components in the airship; and a valve coupled to the ballonet. The valve provides a pathway for air to flow between the ballonet and a plenum chamber, the plenum chamber is formed by the airship, a landing surface, and the inflatable landing system when the inflatable landing system is in contact with the landing surface.

Abstract:
An airship for facilitating transportation to and from one or more locations which are difficult to access or operate such as high above the ground level is disclosed. The airship can also be used in surface missions, The airship includes a cabin and a platform. The cabin is configured on a top portion of the airship. The platform is operatively connected to the cabin. The platform facilitates easy access to the cabin.
Abstract:
A hybrid air vehicle is disclosed in which a cover is provided for a plurality of air cushioned landing pads to reduce drag when airborne. The pad is inflatable to provide an air cushioned during touchdown and deflatable during flight of the air vehicle. The cover can include a first cover portion and a second cover portion. A first cover roller of the first cover portion and a matching second cover roller of the second cover portion abut to cover the corresponding pad. The first cover roller and the second cover roller, which are separate and free from a physical linkage there between, are separable in an eyelid fashion to expose the corresponding pad. A separation gap between the first cover roller and the second cover roller is increased or decreased by roller straps to cover or expose the corresponding pad.
Abstract:
Integration of structure and aerodynamic shape results in a Damage Resistant Unmanned Aircraft, Capable of surviving ground handling and impacts with plants, wires, solid objects and water. The structure dismantles for transport and storage into a small space, that is resistant to damage. The aerodynamic arrangement has a improved ability to fly controllably in the gusty environment that causes difficulty for small light weight aircraft. A method of mounting pneumatic and fabric shapes onto a Damage Resistant Aircraft with parts facilitating a round structure. Use of the pneumatic shapes to adjust the length and stiffness of the post. The post produces tension on the structure that It presses against. Inflatable post ends and an attachment system. Multi piece removable wing tips which allow deflation, access and small folding volume of the inflatable structure. All tension rudders are formed inside the net structure where it is protected from damage.
