摘要:
An apparatus for remotely controlling an aircraft having a self-propelled nosewheel, on the ground, comprises parking brakes; an APU on said aircraft; control means for applying and releasing said parking brakes; control means for turning on and off said APU; transmitting means for transmitting information to said parking brakes and said APU; receiving means for receiving information at said parking brakes; and receiving means for receiving information at said APU.
摘要:
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.

A method of measuring the weight of an aircraft is disclosed. The method comprises, in a self-propelled aircraft undercarriage having a electrical rotating machine, the steps of: measuring the current and voltage going into the rotating machine using current and voltage measuring means, calculating the power into the rotating machine, measuring the speed (or torque or acceleration) of said machine using speed sensing means, and comparing the power and speed (or torque or acceleration) results with a database of power and speed relationships of comparable aircraft of varying weights.

An apparatus for controlling the movement of an aircraft having a self-propelled nosewheel, on the ground, is disclosed. The apparatus comprises a control arm; a control unit; means for transmitting information to said self-propelled nosewheel; means for receiving information at said self-propelled nosewheel; and means for controlling at least one of the speed and direction of said nosewheel; whereby airport ground staff can intuitively control the movements of said aircraft by holding said arm and moving it in the direction of required movement of said aircraft.
摘要:
Methods for fabricating nano-structured surfaces having geometries in which the passage of elementary particles through a potential barrier is enhanced are described. The methods use combinations of electron beam lithography, lift-off, and rolling, imprinting or stamping processes.

In the method of the present invention, electrostatic fields are used to induce heat pumping action of a working fluid. A plurality of heat pumps with no moving parts are used. The operation of the one pump enhances the operation of the next. The method of the present invention is conducive to devices of a wide range of scales. Furthermore, operation at partial power levels is practicable, and precise control of temperature possible. Control is further enhanced by the addition or removal of further units to the system. Reliability should be enhanced, and peak power demands reduced. Wide selection of possible working fluids allows for the elimination of environmentally harmful halocarbons. In one embodiment of the present invention, chemical working fluids are eliminated entirely. In another embodiment, supercooled fluids such as liquid helium may be used while eliminating the wastage commonly encountered using such fluids.

A wheel design is provided for an aircraft landing gear wheel that is configured to maximize the space available within a landing gear wheel well to support a motor driver assembly that drives the aircraft wheel when the aircraft is on the ground. The wheel includes inboard and outboard support walls that are spaced apart a selected distance along the wheel axle so that the motor driver assembly components are substantially completely contained within the wheel space defined by the support walls. The preferred motor driver assembly includes an electric motor and a gear and clutch assembly operatively connected to the wheel to drive the wheel and move the aircraft on the ground. The wheel and motor driver assembly described herein may be retrofitted in an existing aircraft wheel without changing existing landing gear components, including tires, piston, and axle.
