Problems solved by technology

[0004] Both solutions have disadvantages: a single aircraft tug with a large enough engine to power the largest aircraft will waste a lot of energy pulling lighter aircraft; conversely, using aircraft tugs of various sizes requires all higher initial outlay
Larger engines also require more maintenance than smaller engines, resulting in costly and time-consuming tractor repairs
[0007] Optimum practice would therefore be to provide a structure for powering the aircraft tug or mover where the initial power delivery is high, but once the initial resistance is overcome the power delivery is substantially reduced

Embodiment Construction

[0048] First refer to the diagram in the figure 1 with figure 2 , an aircraft tractor 10 is shown, which is an electric hybrid aircraft mobile vehicle having a compression-ignition internal combustion engine, in this case a diesel engine 12 , a generator 14 and at least one electric motor 16 . There is also provided a dual electrical energy storage and supply system 18 comprising a first electrical energy storage and supply means 20 and a second electrical energy storage and supply means 22 different from the first energy storage means 20 .

[0049] Aircraft tug 10 includes a chassis 24 , a cockpit 26 preferably located at a front end 28 of tug 10 (from which an operator 30 can control tug 10 ), a plurality of wheels 32 and an aircraft cockpit located at a rear 36 of tug 10 . Joint area 34 . Typically, aircraft tug 10 has four wheels 32 , although tugs or other types of aircraft movers with different numbers of wheels are contemplated.

Abstract

There is provided a method of moving an aircraft using an aircraft mover (10), preferably an aircraft tractor. The method comprises the steps of: a] accelerating the aircraft up to speed using one or more electric motors (16) drivable by at least a fast-discharge electrical-energy storage and supply device (20) during a high-power requirement of the aircraft mover (10); b] substantially maintaining a speed of the aircraft using a slow-discharge electrical-energy storage and supply device (22) during a low-power requirement of the aircraft mover (10); c] monitoring a charge status of the slow-discharge and fast-discharge energy storage and supply devices (20, 22) and when a predetermined charge status is reached, automatically charging the slow-discharge and / or fast-discharge energy storage and supply devices (20, 22) via an onboard electricity generator (14); and d] regeneratively recharging the slow-discharge and / or fast-discharge electricity-energy storage and supply devices (20, 22) during at least deceleration of the aircraft coupled to the aircraft mover (10). There is also provided a method of controlling the power distribution to the motors (16) within the aircraft mover (10), a dual electrical-energy storage and supply system (18) and controller (50) for implementing said method, a hybrid power delivery system for an aircraft mover incorporating the dual electrical-energy storage and supply system and controller, and an aircraft mover (10) using said systems.

Description

technical field [0001] The present invention relates to a method of moving an aircraft using an aircraft moving machine, in particular but not necessarily exclusively an aircraft traction vehicle, and having a dual electrical energy storage and supply system. The present invention further relates to a method of controlling the distribution of power to an aircraft mobile machine, further to a hybrid power delivery system for an aircraft mobile machine, and further to a dual electrical energy storage and supply device and a method for controlling such electrical power mixing The control member of the power distribution of the aircraft mobile machine. Background technique [0002] Aircraft tugs or movers are heavy vehicles necessary to tow and / or maneuver all types of aircraft. In contemporary aircraft tractors there is usually a diesel compression ignition internal combustion engine with direct transmission to the drive axles or wheels. Therefore, the engine directly provide...
