摘要： Reduced and low work function materials capable of optimizing electron emission performance in a range of vacuum and nanoscale electronic devices and processes and a method for reducing work function and producing reduced and low work function materials are described. The reduced and low work function materials advantageously may be made from single crystal materials, preferably metals, and from amorphous materials with optimal thicknesses for the materials. A surface geometry is created that may significantly reduce work function and produce a reduced or low work function for the material. It is anticipated that low and ultra-low work function materials may be produced by the present invention and that these materials will have particular utility in the optimization of electron emissions in a wide range of vacuum microelectronics and other nanoscale electronics and processes.

摘要： A method for increasing airport airside parking locations without adding infrastructure to the airport is provided. Aircraft equipped with pilot-controllable landing gear wheel-mounted electric taxi drive systems for ground travel are maneuvered forward into remote tarmac stands or non-standard parking locations with the electric taxi drive systems, turned 180 degrees through tight turns, and parked in a nose-out orientation that enables the aircraft to efficiently unload and load passengers. The electric taxi drive systems drive the departing aircraft forward out of the parking locations. Remote tarmac parking locations may be located in areas that do not interfere with arrival and departure of aircraft parking at existing terminal stands. The present method may increase aircraft parking capacity at an airport, provide better utilization of existing tarmac space at the airport, reduce requirements for ground personnel on a per-flight basis, and improve airport ground operations efficiency.

摘要： A method is provided that reduces time to dock an electric taxi drive system-driven aircraft parking in a parallel orientation at an airport terminal. Passenger loading bridges are pre-positioned to substantially align with forward and rear doors of the aircraft. Pre-positioned passenger loading bridges extend from the terminal to locations that align with terminal-facing forward and rear doors when electric taxi systems maneuver the aircraft into the parallel parking orientation. The passenger loading bridge connected to a rear door may be pre-positioned at a height above the ramp surface above or below the height of the aircraft's horizontal stabilizer or below the height of the wing to enhance safety and further reduce connection and passenger transfer time. Connection of the pre-positioned passenger loading bridges with the aircraft doors should require only minimal adjustment before passenger transfer between the aircraft and terminal may begin.

摘要： A system is provided that guides aircraft driven with landing gear wheel-mounted electric taxi drive systems without reliance on airport ground personnel to park the aircraft parallel to an airport terminal with connections to multiple passenger loading bridges, automatically docks the aircraft, and connects the multiple loading bridges to multiple forward and rear doors. Cooperative on-aircraft monitoring systems, airport docking systems, loading bridge and terminal monitoring systems, and processors are integrated to use real time information and guide the aircraft to safely maneuver into and automatically dock in a parallel orientation at a parking location with multiple aircraft forward and rear doors connected to multiple loading bridges. The system may automatically undock the aircraft and retract the loading bridges and guide the electric taxi drive system-driven aircraft out of the parking location without reliance on airport ground personnel.

摘要： An improved ground collision avoidance system and method is provided for aircraft driven during ground operations by electric taxi drive systems. One or more monitoring devices employing scanning LiDAR technology may be mounted in exterior locations on or near aircraft landing gears or aerodynamically in locations on the aircraft fuselage selected to generate panoramic three-dimensional images from any point of view within or without the aircraft as the aircraft is driven independently within an airport ramp area. The point of view images are transmitted in real time to displays in the aircraft cockpit and may be transmitted to displays outside and remote from the aircraft, allowing the pilot and airport personnel to monitor the aircraft moving within the ramp environment and to respond quickly to control the aircraft's electric taxi drive system-powered ground travel to avoid and prevent a potential collision.

摘要： A method for designing and operating an aircraft nose landing gear wheel-mounted electric taxi system moves aircraft with optimal torque during a broad range of ground travel conditions. Electric taxi system components may be sized to produce optimal ground travel torque to move aircraft during the majority of aircraft ground travel conditions and operated to produce a maximum or breakaway torque to move the aircraft with the electric taxi system when a higher level of torque is required. Turning the nose landing gear wheels to a selected angle or through a range of angles simultaneously as the electric taxi system is operated produces the breakaway torque required to get the aircraft moving. When lower torque is needed, the aircraft may be driven with the nose landing gear wheels parallel to the longitudinal axis to produce optimal torque for electric taxi system-powered aircraft ground travel.

摘要： A force limiting system and method are provided for limiting loads in aircraft nose or main landing gear having wheels powered by taxi drive systems mounted within the landing gear wheels to drive aircraft on the ground. The force limiting system may include mechanical components selected to limit or minimize spin-up mass and to releasably connect the taxi drive system to a landing gear wheel section so that operation of the taxi drive system to drive a landing gear wheel is prevented in the presence of a predetermined maximum load. The load limiting system employs mechanical components engineered to securely connect the taxi drive system to the landing gear wheel during operation and to release the taxi drive system from connection to the wheel when loads applied to system components exceed an established or recommended maximum load.

摘要： A method for increasing and optimizing the value of airport terminal exterior advertising is provided that significantly increases exposure of exterior advertising displays on the airside or non-public side of an airport terminal to passengers on arriving, parked, and departing aircraft. The movement of aircraft equipped with non-engine drive means on landing gear wheels for autonomous ground movement is controlled within an airport ramp area so that the aircraft moves in only a forward direction toward and away from a terminal parking place and parks in an orientation parallel to the terminal. The direction and orientation of aircraft ground travel and parking parallel to a terminal enhances and improves the visibility of exterior advertising displays to a maximum percentage of the passengers in the aircraft as the aircraft travels within the ramp area and parks between arrival and departure.

摘要： A method for maximizing traction in an aircraft drive wheel powered by non-engine drive means controllable to move the aircraft on the ground without reliance on the aircraft's brakes and dependence on friction defined by a mu-slip curve. The non-engine drive means is operated to control wheel speed and maintain the powered drive wheel in a maximized optimal traction condition when driving torques are applied to the drive wheel. Traction can be automatically maximized and maintained within an optimal range defined by a relationship between slippage and braking for maximum efficiency of aircraft ground travel under a wide variety of surface, weather, temperature, tire, and other conditions.

摘要： A method is provided for improving both landing gear wheel drive assembly performance and energy efficiency performance in an aircraft equipped with one or more landing gear wheel drive assemblies to move the aircraft autonomously on the ground without reliance on the aircraft's engines. Aircraft moved on the ground by thrust from aircraft engines may also show improved energy efficiency. The present method employs a discovered relationship between aircraft tyre pressure and landing gear wheel drive assembly performance and maintains aircraft tyre inflation pressure at an optimum high pressure that enhances both landing gear wheel drive assembly performance and aircraft energy efficiency while the aircraft are driven on the ground by the landing gear wheel drive assemblies. Operation of the landing gear wheel drive assembly may be automatically prevented by a failsafe mechanism when optimum high tyre inflation pressure levels are not maintained during aircraft ground travel.
