Abstract
An aircraft wheel is driven by a wind turbine 7 or motor 8 (also figure 4) releasably secured to the undercarriage 9 of the aircraft, and which will rotate the aircraft wheel with a rotational speed comparable to the relative ground speed of the aircraft on approach to landing. An electric or fluid driven motor (eg. hydraulic) may be provided, driving the aircraft wheel through a gearbox to increase or decrease the speed of the wheel. Alternatively, the wheel may comprise a tyre wherein the wall or tread thereof act as wind-driven turbine.
Description
AIRCRAFT UNDERCARRIAGE WHEEL DRIVER
This invention relates to an aircraft undercarriage wheel driver.
Aircraft undercarriage wheels are well known devices which are used on aircraft to facilitate take off and landing and are mounted on the underside of the aircraft via a shaft or axle.
Aircraft undercarriage wheels are, however, used on landing and do not rotate until in contact with the surface on which the aircraft lands. Moreover when they are in use as as a means for landing the aircraft the wheel must of necessity not rotate with a rotational speed close to or the same as the relative ground speed of the surface on which the aicraft lands.
According to the presentsinvention there is provided an aircraft undercarriage wheel driver comprising of a drive or rotor shaft in place of or coupled to the axle, a wind turbine or motor to drive the rotor shaft, means for releasably securing the wind turbine or motor to the aircraft under- carriage thereof which will rotate the aircraft wheels with a rotational speed comparible to the relative ground speed of the surface on which the aircraft wheel contacts on landing.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which
Figure 1 shows in perspective, an aircraft wheel assembly with wind turbine blades mounted onto a rotor in place of the wheel hubshaft or axle thereof;
Figure 2 illustrates a single aircraft wheel with a wind turbine in position on each side of the wheel; and
Figure 3 illustrates an aircraft wheel driven by a motor rotor shaft in position through the aircraft wheel hub; and
Figure 4 illustrates a motor in position to drive the aircraft wheel by a different means.
Refering to the drawing the aircraft wheel driver comprises of a rotor (5] in place of the wheel axle (6] and a wind turbine [7] or motor [8] such as to rotate the wheel releasably secured to the aircraft undercarriage (9] thereof by, for example, a number of bolts, clamps, screws or application of weld or similar means ( not shown ). The aircraft undercarriage wheel driver can be permanently secured into the hub of the aircraft wheel as indicated in Figure 1 and 2 or attached to the aircraft wheel shaft by use of a coupling or similar means ( not shown ).
In order to rotate the aircraft wheel a source of power is supplied by, for example, an electrically driven motor (8] or by air contacting the wind turbine [7]. The aircraft wheel will be caused to rotate with a rotational speed similar to the relative ground speed of the aircraft on approach to landing ( not shown ). Prior to surface contact the aircraft wheel speed can be adjusted by, for example, a gearbox so that the difference in aircraft wheel and ground speed on contact is low or approaching zero ( not shown ).
In order to provide a means for securing the wind turbine to the wheel, the wind turbine may be provided with, for example, bolts to secure it directly onto the aircraft wheel ( not shown ).
Claims (11)
1 An aircraft undercarriage wheel driver comprising of a rotor or drive shaft linked by a coupling or similar means to the aircraft wheel axle, a wind turbine or motor to drive the rotor or drive shaft, means for releasably securing the wind turbine or motor to the aircraft undercarriage thereof which will rotate the aircraft wheels with a rotational speed comparible to the relative ground speed of the surface on which the aircraft wheel contacts on landing.

7 An aircraft undercarriage wheel driver as claimed in
Claim 1, Claim 2, Claim 3, Claim 4, Claim 5 or Claim 6, wherein the wheel driver means is provided to increase or decrease the speed of the aircraft wheel using a gearbox or other means.
8 An aircraft undercarriage wheel driver as claimed in any preceding claim, wherein the aircraft wheel tyre means is provided for the tyre wall or tread to act as a wind turbine.
