摘要： The present invention provides a method for maneuvering and aligning aircraft equipped and driven during ramp ground travel with landing gear wheel-mounted electric taxi drive systems that have deviated from taxi line travel paths and for maneuvering the electric taxi drive system-driven aircraft to park accurately to align with locations of parking stops when the aircraft nose landing gear wheels stop beyond or short of a parking stop. The aircraft pilot can, without waiting for a tug or starting aircraft engines, precisely maneuver the aircraft with the electric taxi drive systems while viewing the taxi line and parking stop location in real time with an optional camera and sensor system while maneuvering the aircraft in forward or reverse and lateral directions to align the aircraft nose wheels with the taxi line path and to accurately position the nose landing gear wheels at the parking stop.

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： 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： 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 cockpit control system and method for efficiently controlling ground travel in an aircraft equipped with an engine-free electric taxi system are provided. The cockpit control system is configured with a display that provides a maximum amount of information during aircraft ground movement with a minimal amount of input from and distraction to pilots or cockpit crew to facilitate essentially hands free operation and control of aircraft ground travel. System test and drive procedures ensure safe aircraft ground travel with the engine-free electric taxi system. Constant pilot hand or other input is not required to achieve safe and maximally efficient aircraft ground travel powered by the aircraft's engine-free electric taxi system or, under selected defined conditions, by the aircraft's engines to achieve this maximum efficiency. The system may further be designed to be uninterruptible by unauthorized persons.

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.
