Hydrogen powered air vehicles that in some embodiments can fly with very long endurance (10 or more days) at altitudes over 60,000 ft carrying payloads of up to 2,000 pounds. Embodiments may include features such as large wingspan relative to fuselage and an all composite or partial composite structure for light weight and strength. The aircraft of the invention use one or more internal combustion engines adapted for hydrogen combustion, each engine driving propellers. The hydrogen fuel is stored on board in containers, located within the fuselage, as a cryogenic liquid, and is vaporized in a heat exchanger before delivery to the internal combustion engine.

Ground carts to support skid equipped aircraft and to maneuver these craft safely on the ground during taxiing for take off, recovery, servicing, and transport to maintenance or storage. The ground carts provide the capability to minimize risks of damage to aircraft during towing by lifting the aircraft off the ground. Further, an embodiment of the ground cart of the invention includes the ability to rotate the aircraft on a cart platform up to 90&#xb0; from the direction of forward motion of the cart to facilitate movement in and around the airport apron/hanger and to counter cross winds during take off. In addition, carts may be controlled from the aircraft, for example to provide for steering control until the aircraft is launched, cart braking, platform rotation, and other maneuvers.

A set of logic cells is hierarchically grouped to form groups to be placed on an integrated circuit for gate array layout. A user interface allows a user to interact with a placement system. The system is supplied with input design files defining the integrated circuit, the cells to be grouped, the groups to be placed, and input/output buffers to be placed on the perimeter of the integrated circuit for connecting the groups with external circuitry. The system reads the input design files to create a database used for placing desired input/output buffers and for hierarchically grouping the cells and placing the groups. The groups are defined by their size, determined using utilization and aspect ratio values of the areas where the cells are to be placed. The user is allowed to move the buffers and groups to any valid locations within the integrated circuit.
