Abstract: A method of moving an aircraft using an aircraft mover that includes: a] accelerating the aircraft up to speed using one or more electric motors drivable by at least a fast-discharge electrical-energy storage and supply device during a high-power requirement of the aircraft mover; b] substantially maintaining a speed of the aircraft using a slow-discharge electrical-energy storage and supply device during a low-power requirement of the aircraft mover; c] monitoring a charge status of the slow-discharge and fast-discharge energy storage and supply devices and when a predetermined charge status is reached, automatically charging the slow-discharge and/or fast-discharge energy storage and supply devices via an onboard electricity generator; and d] regeneratively recharging the slow-discharge and/or fast-discharge electricity-energy storage and supply devices during at least deceleration of the aircraft coupled to the aircraft mover.

Abstract: There is provided a method of moving an aircraft using an aircraft mover, in various instances, an aircraft tractor. The method comprises: a] accelerating the aircraft up to speed using one or more electric motors drivable by at least a fast-discharge electrical-energy storage and supply device during a high-power requirement of the aircraft mover; b] substantially maintaining a speed of the aircraft using a slow-discharge electrical-energy storage and supply device during a low-power requirement of the aircraft mover; c] monitoring a charge status of the slow-discharge and fast-discharge energy storage and supply devices and when a predetermined charge status is reached, automatically charging the slow-discharge and/or fast-discharge energy storage and supply devices via an onboard electricity generator; and d] regeneratively recharging the slow-discharge and/or fast-discharge electricity-energy storage and supply devices during at least deceleration of the aircraft coupled to the aircraft mover.

Abstract: The present disclosure provides drilling and tripping equipment packages and control schemes and methods using two or more lifting systems that operate simultaneously and continuously in a synchronized manner such that the feeding of tubular into or out of a well bore is achieved with continuous or near continuous movement, without the need for periodic interruptions. The drilling and tripping equipment packages and control schemes are also able to rotate the tubular in the well bore with continuous speed and torque sufficient for both drilling and back-reaming operations. The drilling and tripping equipment package and control scheme is additionally able to circulate drilling fluid into the internal bore of the tubular with sufficient pressure and flow to facilitate both drilling and back-reaming operations, with minimal interruption to circulation.
