Patent number: 4919489Abstract: A vehicle for overcoming obstacles includes a wheel having an elastomeric flexible annulus upon which the wheel normally rides. Parallel spaced sprockets receive the annulus and include individual cogs which extend less radially outwardly than the annulus. When an obstacle is encountered, the flexible annulus yields, thereby enabling a protruding cog to engage the obstacle and pivot around it thereby lifting the vehicle over the obstacle.Type: GrantFiled: April 20, 1988Date of Patent: April 24, 1990Assignee: Grumman Aerospace CorporationInventor: M. Alan Kopsco

Patent number: 4685641Abstract: A transient air and surface contact vehicle for transporting a person has a fuselage structure for carrying a person. A vehicle support extends from the structure and abuts a surface and thereby supports the vehicle at a predetermined distance above the surface. A buoyancy control device mounted on the structure and on the vehicle support provides for the buoyancy required to keep the vehicle afloat while stationary and at low speeds. At high speed the dynamic pressures generated at the bottom of the struts provide the supporting forces. A power source is mounted on the structure for moving the vehicle along the surface at the predetermined distance above the surface. A position control mounted on the structure produces a positive pitching moment to cause the vehicle to become airborne, a negative pitching moment to maintain the vehicle in surface-following contact with the surface and both moments to control the altitude of the vehicle when it is airborne.Type: GrantFiled: August 26, 1985Date of Patent: August 11, 1987Assignee: Grumman Aerospace CorporationInventors: Jerome Kirsch, M.

Patent number: 4582108Abstract: An automatic tire inflation-pressure regulating system for wheeled vehicles with pneumatic tires. The system has a system control assembly in the vehicle operator's compartment, control signal transmitter assemblies on the vehicle body in close proximity with each vehicle road wheel, and a tire pressure-regulating wheel assembly on each wheel. The transmitter assemblies convert electrical command signals initiated by the control assembly to RF signals that are received by an electronic module in each wheel assembly. Means in each wheel assembly selectively deflate or inflate their respective tires in response to the RF control signals. Gas under pressure for inflating the tires is provided either by a plurality of gas generators or by a pressurized gas-generating liquid.Type: GrantFiled: July 26, 1984Date of Patent: April 15, 1986Assignee: Grumman Aerospace CorporationInventors: Edward G. Markow, Jerome Kirsch, M. Alan Kopsco

Patent number: 4505442Abstract: A transient surface contact vehicle for transporting a load from a surface starting point to a surface end point has a structure for carrying the load from the starting point to the end point. A vehicle support extends from the structure. A buoyancy control device mounted in the structure is coupled to the vehicle support for selectively making the support buoyant and non-buoyant whereby when the support is buoyant it abuts the surface of a body of water thereby supporting the vehicle at a predetermined distance above the surface of the body of water. An acquisition sensor mounted on the structure initiates water surface operations. A sensor is mounted on the structure and cooperates with the acquisition sensor to energize upon tracking of the target and to move the vehicle along the water surface to impact with the target at the end point. A position control mounted on the vehicle produces a negative pitching moment to maintain the structure in surface-following contact with the body of water.Type: GrantFiled: June 20, 1983Date of Patent: March 19, 1985Assignee: Grumman Aerospace CorporationInventors: Jerome Kirsch, M.

Patent number: 4459167Abstract: A run-flat pneumatic tire having an annular structural compression element in the inside surface of the crown thereof, which compression element is stabilized by a multiplicity of closely spaced spoke-like radial elements in the tire sidewalls such that de-pressurized operation of the tire without damage is possible. The compression element is a helix with closely spaced coils wound from a rod of a cross-sectional shape selected from various solid and tubular configurations. Round, square, and rectangular coil cross-sectional configurations are shown as are interlocking convex/concave, tongue/groove arrangements. Methods of installing the helical compression element in the tire as by winding up the helix to reduce its diameter such that it can pass through the beads, or by introducing one end of an end coil of the helix over one of the beads into the interior of the tire and providing a relative rotation to feed the helix into the tire are taught.Type: GrantFiled: December 12, 1983Date of Patent: July 10, 1984Assignee: Grumman Aerospace CorporationInventors: Edward G.
