    摘要： In one or more embodiments, the ground roll assist system is based on the electric in-wheel motors integrated with the main landing gear of an aircraft and linked to the aircraft control system. It is well known that modern electric motors possess superior torque density characteristics, potentially exceeding best in class internal combustion engines by more than an order of magnitude. Furthermore, electric motors performance is generally thermally limited, which makes it possible to achieve even higher performance for a short period of time.

    摘要： An aircraft landing gear is disclosed including a shock-absorbing main leg having a sprung part for attachment to an aircraft and an un-sprung part including a slider and an axle carrying at least one wheel, the wheel having a toothed ring gear; a drive transmission mounted externally on the sprung part, or on the un-sprung part, of the main leg, the drive transmission having at least one motor and a drive pinion for meshing with the toothed ring of the wheel; and an actuator for lifting the drive transmission into and out of driving engagement with the toothed ring and for maintaining the driving engagement as the landing gear deflects during a ground taxiing operation. Also, a method of operating the aircraft landing gear.

    摘要： An improved serviceability gearing element generally includes a support having a plurality of obstacles for co-operating with teeth of a neighboring gearing element. The gearing element further includes a pin, a roller mounted to move in rotation about the pin via a rotary guide, blocking bearings shaped substantially to prevent the roller from moving in translation along the pin, and one or more fasteners for fastening at least one of the blocking bearings to the support.

    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.
