An aircraft landing gear arrangement comprising a wheel with a brake 6, one or more fan blades 7a, 7b to cool the brake, and a brushless DC motor 8 for rotating the fan blade(s). An aircraft comprising such a landing gear arrangement and a method of cooling an aircraft landing gear brake are also provided. The motor may be powered by energy harvested from kinetic energy of the rotating wheels, or from the heat energy emitted from the brakes captured by a photovoltaic material. The motor may be located adjacent or within a wheel hub 3 with an outer portion on which a tyre is mounted, and within a volume 17 defined by a cover 14 mounted on the wheel. A lid 16 may prevent debris entering the volume 17. The motor may operate dependent on the phase of flight of the aircraft, or a sensed parameter such as temperature.
