Abstract: An undercarriage wheel is disclosed comprising an axle member that supports a drive member, for example but not limited to a compact high torque electric motor, a wheel member driven by said drive member, and a tire attached to the wheel member, wherein the tire bulges in the width dimension of the wheel, wherein the drive member protrudes from the wheel member and thus occupies at least some of the additional width made available by the bulge of the tire. A further aspect of the invention is an undercarriage wheel that comprises an axle member that supports a drive member, for example but not limited to a compact high torque electric motor, a wheel member driven by said drive member, and a low-profile tire attached to the wheel member. Since the profile of the tire is low, additional space is available inside the wheel for the drive member.

Abstract: A system for minimizing damage on collision to a vehicle having at least one self-propelled wheel is disclosed. The system comprises a motor in a wheel of said vehicle which drives the vehicle, means for measuring the speed of said wheel, means for measuring the torque of said motor, means for monitoring the ratio of the torque of the motor to the speed of the wheel, and means for stopping said motor when torque:speed ratio exceeds an acceptable value.

Abstract: An apparatus for driving a taxiing aircraft is disclosed, comprising, in an aircraft, two self-propelled nosewheels, each having an electric motor; equipment for flight; dual-function controlling means for controlling said equipment for flight and said nosewheels, said dual-function controlling means being disposed in the cockpit of said aircraft; sensing means; and switching means, —wherein said switching means are operable to switch the function of said dual-function controlling means between controlling said equipment for flight and controlling said nosewheels. Said dual function controlling means may control speed and/or steering of the aircraft. Second controlling means may be provided, and may be disposed externally to the aircraft.

Abstract: A method for reducing the turnaround time of an aircraft having at least one self-propelled undercarriage wheel comprising the step of: moving the aircraft to a required location using at least one self-propelled undercarriage wheel; wherein thrust equipment, (e.g. turbines) are turned on only when needed for takeoff or prior to landing, and are turned off until takeoff or after landing; whereby departing equipment, arriving equipment, and turnaround equipment are not at risk from operating thrust equipment, (e.g. turbines). An apparatus for reducing the turnaround time of an aircraft is disclosed comprising a control unit for facilitating voice communication between a pilot and ground staff.
