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. Said control unit may further comprise a control arm for inputting the required direction of movement of said nosewheel; means for transmitting direction information to said self-propelled nosewheel; means for receiving direction information at said self-propelled nosewheel; and means for controlling the direction of said nosewheel. The control unit may also comprise means for turning on and off an APU, parking brakes, and other aircraft features.
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. Preferably, the drive member occupies at least some of this additional space, and has sufficient power to be able to propel an aircraft to which the undercarriage assembly is attached, either alone or in combination with other self-propelled undercarriage assemblies attached to the aircraft.
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:
An apparatus for facilitating voice communication between persons outside an aircraft and persons inside an aircraft, is disclosed, comprising: an external control unit comprising: voice sensing means; transmitting means for transmitting voice information to persons in said aircraft; receiving means for receiving voice information from persons in said aircraft; and amplifying means for enabling said voice information to be heard; and an in-aircraft control unit comprising: voice sensing means; transmitting means for transmitting voice information to persons external to said aircraft; receiving means for receiving voice information from persons external to said aircraft; and amplifying means for enabling said voice information to be heard.
Abstract:
It is the principal object of the invention to provide a new and improved electrical power unit for use in automobiles, on aircraft, or for local generation of electrical power. In one embodiment of the present invention, an electrical power unit comprises: a combustion chamber that burns fuel to produce heat energy; and a thermionic device that converts the heat energy into electrical energy. In another embodiment of the present invention, the electrical power unit additionally comprises an electric motor. In a further embodiment, the electrical power unit additionally comprises an electrically power air compressor, an electrically power hydraulic compressor, and an electrical power conditioning unit.
Abstract:
The present invention is a method for reducing nanoscale surface roughness. The method involves exposing the surface to an environment that preferentially promotes evaporation of material from the region of nanoscale roughness. The methods involve either heating the surface, or flushing an inert gas across the surface, or a combination of both.
Abstract:
A method is disclosed for the induction of a suitable band gap and electron emissive properties into a substance, in which the substrate is provided with a surface structure corresponding to the interference of electron waves. Lithographic or similar techniques are used, either directly onto a metal mounted on the substrate, or onto a mold which then is used to impress the metal. In a preferred embodiment, a trench or series of nano-sized trenches are formed in the metal.
