Filed:

Dec 24, 2002

Appl. No.:

10/328665

Inventors:

Holger H. Streckert - Rancho Santa Fe CA, US
Linden P. Blue - La Jolla CA, US

Assignee:

General Atomics - San Diego CA

International Classification:

C25B001/08

US Classification:

204258

Abstract:

An electrolyzer for generating hydrogen by the electrolytic dissociation of water employs anode and cathode half-cells, separated by a planar polymer-based solid electrolyte, and includes a water reservoir for independently maintaining a desired level of water in the anode and cathode half-cells. A hydrogen exit chimney extends vertically upward from each cathode half-cell and enters a separation chamber; a gas exit passageway therefrom is closed by a separation membrane that allows the passage of Hbut rejects liquid HO, while a return water passageway enters near the bottom of the cathode half-cell. The half-cells are preferably formed by molded plastic frames that are arranged as a cell stack containing a plurality of electrolytic cells, with flat metal anodes and cathodes being respectively sandwiched about the solid electrolyte membrane in each cell. A pair of flat crushable metal plates are located at each end of the cell stack adjacent a pair of pressure plates that exert axial squeezing pressure to seal the cells. Specially designed, dual metal-hydride cartridges are used to provide larger quantities of Hfrom a single cartridge; a high temperature metal hydride is provided in a rear region of the cartridge that is heated by an electrical resistance heater to a temperature of about 200 C.

Abstract:

A windshield for a pressurized aircraft includes a single transparent unit that functions structurally to allow pressurization of the aircraft and to support the aircraft's fuselage in response to external loads. The windshield also functions operationally to provide the pilot with an unobstructed field of vision through an extended arc of more than two hundred degrees. For its manufacture, layers of the transparent unit are respectively bent along a straight center line to establish two curved portions that are symmetrical relative to a common plane. The layers are then laminated.

Abstract:

A portable electronic device incorporates PEM fuel cells and is designed to operate by the reaction of hydrogen from a hydride-containing fuel container and oxygen from the air, while efficiently removing the product water by a novel water transportation system. Temperature is effectively controlled by placing a plurality of fuel cell subunits as a generally planar array in the lid of the PC adjacent a heat transfer plate. A particularly efficient resupply system is provided where an electrolyzer that supplies H at a pressure sufficient to continue to power the PC and simultaneously recharge an operatively-connected container and a second spare container in the electrolyzer.

Abstract:

A main landing gear assembly for an aircraft has an upper beam and a lower beam. The proximal ends of the upper and lower beams are each connected to a trunnion assembly that is mounted on the fuselage or wing of the aircraft. The distal ends of the upper and lower beams are each affixed to an axel support structure on which a main wheel of the landing gear assembly is mounted. In the gear assembly, the upper beam and the lower beam are coplanar and act together, in combination, to accommodate a planar flexure of the gear assembly during aircraft takeoffs and landings.

Abstract:

A ground vehicle with flight capability is described including a deployable airfoil configured to deploy from a stowed configuration to a deployed configuration, preferably during ground locomotion of the vehicle. The vehicle also includes a deployment mechanism for automatically deploying the airfoil from the stowed configuration to the deployed configuration. An automated retrieval mechanism may also be included for returning the airfoil to the stowed configuration. Also described are methods of transitioning a vehicle from ground locomotion to flight, including deploying a ram-air airfoil from a stowed configuration to a deployed configuration during ground locomotion of the vehicle.
