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 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.

摘要： A method is provided that enhances wheel drive assembly acceleration, heat reduction, and energy efficiency performance during ground travel in aircraft equipped with landing gear wheel-mounted drive assemblies to move aircraft on the ground without reliance on the aircraft's engines or external tow vehicles. Inflation pressure levels of tyres on the landing gear wheels are monitored with pressure and/or temperature sensors to determine and maintain an optimum defined high inflation pressure level for the specific kind of aircraft tyre or the aircraft. A clutch-activated drive assembly may be prevented from transferring torque and driving the aircraft when the optimum high inflation pressure levels are not present in the tyres during ground travel. Tyre pressures may be manually or automatically adjusted in response to processed sensor information to maintain the optimum high inflation pressure level in all tyres as the aircraft is driven with the drive assemblies or with engine thrust.

摘要： A method for improving both drive system performance and energy efficiency performance both in an aircraft equipped with one or more drive wheel drive systems to move the aircraft autonomously on the ground is provided and in an aircraft that relies on its engines for ground movement. Achieving these objectives takes advantage of a discovered relationship between aircraft tyre pressure, drive system performance, and energy efficiency. Monitoring and maintaining tyre inflation pressure of an aircraft's tyres at an inflation level near a high end or recommended maximum cold or hot operating pressure for a specific kind of aircraft tyre on a specific aircraft not only improves drive wheel drive system performance, but also substantially and significantly improves energy efficiency in all types of aircraft.
