    Abstract: An efficient system and method are provided wherein aircraft may be retrofitted with non-engine drive means controllable to power landing gear wheels to move the aircraft autonomously during ground movement without engines or tow vehicles so that existing landing gear structures are employed to achieve force distribution and load transfer. Non-engine drive means capable of powering a landing gear wheel to move the aircraft during taxi are integrated into existing landing gear designs so that excess drive forces are transferred and distributed through previously evaluated and certificated landing gear structures, including tow fittings, determined to be capable of handling such forces, which eliminates changes to the landing gear and facilitates retrofit and certification. Engines-off taxi technology can be rapidly designed and developed to be retrofitted on existing aircraft nose and/or main landing gear and then efficiently certificated.

A level of thrust is dynamically identified using a drag on the aircraft needed to substantially maintain a speed of the aircraft in a turn to form an identified level of thrust during turning of the aircraft. The turn of the aircraft is performed using the identified level of thrust.

  • Patent number: 9033273
    Abstract: An aircraft ground control system that moves an aircraft on the ground between landing and take off without external mechanical assistance from airport tugs or tow vehicles or reliance on thrust produced by the aircraft's engines is provided. The aircraft ground control system interfaces only with an aircraft auxiliary power unit or other aircraft power supply, but otherwise operates independently of aircraft systems. A system integrator and controller links cockpit controls designed to actuate the transmission of power to system components and to activate system components only under predetermined conditions with selectively activatable drivers in driving connection with one or more aircraft wheels to move the aircraft on the ground at selected torques and speeds.

  • Publication number: 20150129713
    Abstract: Control of aircraft steering during ground travel is provided in an aircraft equipped with an engines-off wheel drive system controllable to move the aircraft autonomously on the ground without reliance on the aircraft's main engines or external tow vehicles. The wheel drive system is designed to interact with the aircraft's nose wheel hydraulic steering system to augment or replace the hydraulic steering system with the operation of the wheel drive system at taxi speeds, particularly at very low taxi speeds and even when the aircraft is stopped, to steer the aircraft as it maneuvers through turns during ground travel between landing and takeoff and at other times.

  • Publication number: 20150129712
    Abstract: A method for improving airport and ramp throughput is provided. The method minimizes the time interval between an aircraft's landing and takeoff by independently moving the aircraft with an onboard electric driver that drives at least one of the aircraft's wheels on the ground without the aircraft's engines. Turnaround time and aircraft idle time are reduced by eliminating engine operation while the aircraft is moving in the ramp area. The time between when an aircraft is not moving between pushback and taxi forward is substantially eliminated, leading to more efficient ramp operations as ramp space is freed for through traffic.

  • Patent number: 9022316
    Abstract: A failsafe system and method for ensuring the safe operation of an aircraft with a ground movement system to drive the aircraft independently on the ground is provided. The system includes at least one aircraft nose or main drive wheel powered by an onboard wheel driver responsive to sensed aircraft and ground movement system operating parameters to continue operation in response to parameters within normal limits or to prevent continued operation if sensed parameters are outside normal limits and indicate continued operation to be unsafe. The onboard wheel driver includes a locking assembly responsive automatically or manually to signals indicating sensed parameters to lock the onboard wheel driver in an activated or an inactivated condition, depending on whether operation of the ground movement system can be continued safely.

  • Publication number: 20150097077
    Abstract: A ground propulsion assembly for an aircraft includes an axle, a wheel rotatably connected to the axle, and a transmission. The transmission includes a housing mounted proximate the axle and a drive element disposed at least partially outside of the housing and operatively connected to a power input. A disengagement spring is disposed between the transmission and the axle and the disengagement spring is configured to urge the drive element out of engagement with the wheel. An actuator is operatively connected between the transmission and the axle, the actuator being configured to selectively generate a force in opposition to the disengagement spring such that the drive element moves relative the wheel and operatively engages the wheel to transfer torque to the wheel.

  • Patent number: 8998129
    Abstract: Aircraft landing gear including an axle pivotally connected to a bogie beam and a locking device. The locking couples the axle to the bogie beam, and has a movable member and a follower. The movable member is movable between first and second configurations. Movement of the movable member towards the second configuration causes corresponding movement of the follower so as to transfer a steering force to the axle through the follower which causes the axle to rotate in a first direction. With the movable member in the first configuration, the follower is in a first configuration that inhibits the movable member being moved by an external force applied to the axle. With the movable member in the second configuration, the follower in a second configuration that permits the movable member to be moved by an external force applied to the axle.
