The invention is a hovercraft with multiple lift chambers which are operable independently of each other. Independently-operable pivot arm assemblies connect each lift chamber to the hovercraft main body, and his gives the hovercraft the ability to travel over uneven surfaces, traverse obstacles that would block conventional hovercrafts, and climb or descend even severe inclines. The hovercraft also includes side thrusters which allow it to maintain its vertical position on an incline while traveling laterally across the incline.

A combination floating pontoon boat and air-cushion supported hovercraft having a frame and a plurality of pontoons pivotally and retractably mounted to the frame for pontoon boat mode, and a second position extending laterally outward from the frame in hovercraft mode. A skirt is attached to and extends from the frame, the skirt on a first position being retracted against the bottom of the frame. In a second position, the skirt extends downward from the frame and forms an air-receiving pocket beneath the frame for hovercraft operation. A first power system moves the frame through water when the pontoons are in their first position. A second power system drives air into the air-receiving pocket when the skirt is in the second or hovercraft position, and a third power system propels the frame in a longitudinal direction when air is driven into the air-receiving pocket.

A flexible skirt-cell system is provided for a hovercraft having a propulsion system mounted to interface with water and a flexible skirt having an upper flexible panel section and a lower flexible finger section. The panel section extends around the bow, stern and two sides of the hovercraft hull and the finger section extends around the hull below the panel section and is connected to the panel section from a forward-abeam location and forward along the two sides and across the bow. Fans create pressurized air that is fed through air ducts to form a pressurized air cushion that supports the hovercraft. Interconnected flexible cells are connected between the panel and finger sections from the forward-abeam locations rearward to the stern. Additional air ducts pass pressurized air from the fan units to inflate the cells, thereby elevating the stern and raising the propulsion system above the water.

A fluid-cushion supporting arrangement for horizontal conveyance comprises a supporting platform having a center and a distal portion; a flexible angular sealing element arranged under the platform in the region of the distal portion and forming a sealing piston. The sealing piston has a substantially horizontal leg which extends toward the center and forms together with the supporting platform a fluid chamber, and a substantially vertical leg which forms together with the supporting platform a control pressure chamber. The vertical leg is vertically and adjustably inserted in the control pressure chamber. Inlet means are provided for supplying fluid into the fluid chamber. A pressure-regulating arrangement in fluid communication with the fluid chamber and the control pressure chamber regulates the fluid pressure. The vertical leg comprises a plurality of reinforcement elements including at least one metallic strip.

The present invention provides a moving carrier that sticks to the surface of an object capable, with ease, of broadwise or transverse movements in the direction transecting its traveling direction. The moving carrier of the present invention has at least two sets of driving wheels or one set of caterpillar on each of its right and the left sides relative to its traveling direction; one randomly selected contact area from among a number of contact areas between the driving and moving means and the traveling surface on one of the right or the left side of the carrier relative to its traveling direction also randomly selected is located in the vicinity of the center of a sticking force acting on the carrier, and the other contact areas are located away from the center of the sticking force; the other contact areas slide sideways when the moving carrier gyrates with the randomly selected contact area as the pivot.

A surface effects skimmer vehicle generates a downward air flow into a tunnel under a main hull to lift the main hull off an adjacent surface, and rearward air flows for thrust. The air flows are generated by ducted fans or jet engines, and directed to the rear and/or down by controlling the degree of opening of a Deflector Air Gate (DAG) on the bottom of the main hull. The tunnel includes tunnel edges to contain the downward air flow under the main hull for surface lubrication. The vehicle further includes a rear portion with horizontal and vertical stabilizers to provide air-craft like behavior.
摘要:
A device for moving a tire assembly about a floor surface and mounting the tire assembly to a vehicle, the device includes a platform configured for moving about the floor surface, a pneumatic source for providing a layer of air between the platform and the floor surface beneath said platform, and a support mounted on the platform. The support defining a horizontally extending central axis and is configured to receive and support the tire assembly. An elevator is connected to the platform and the support, and is configured to raise and lower the support relative to said platform. The device is supported on the layer of air so that the platform is movable above the floor surface.
