The invention provides a method of reducing the cooling time for disks of a brake () of an aircraft wheel () fitted with a heat screen () extending between the wheel and the disks of the brake, and mounted to rotate on aircraft landing gear about an axis of rotation, the method comprising making perforations () through the heat screen to allow air heated by the disks to pass through the heat screen towards the wheel, the perforations being provided with obstacles to block any radiation from passing directly from the disks towards the wheel.

Perforated heat screen for a braked aircraft wheel

A method of reducing the cooling time of disks of a brake () of an aircraft wheel () fitted with a heat screen () extending between the wheel and the disks of the brake and mounted to rotate on an aircraft undercarriage about an axis of rotation, the method including making obstacles () on the heat screen, which obstacles project from a face of the heat screen that faces towards the brake disks.

The invention provides a method of mounting an aircraft wheel drive member () on an undercarriage having an axle () that carries the wheel and that is provided with a torque plate () having an outside face against which a brake can be fitted, the method comprising the steps of fitting a support () that bears against an inside face of the torque plate opposite from its outside face against which a brake () is fitted, and of fitting the drive member on the support.

Method of fastening an aircraft wheel drive member on an undercarriage carrying a wheel

An aircraft wheel having a rim having brake discs driving keys (). The wheel has a rotational driver mechanism () which includes a drive gear () associated with coupling members () of the drive gear to the rim of the wheel. The coupling members are fixed to the rim by fixing members () introduced into orifices of the rim extending at an end of the keys which are also used to hold heat shields protecting the rim.

Aircraft wheel equipped with means for the rotational driving thereof by a drive actuator

An aircraft wheel comprising a rim adapted to receive a tire, and a hub connected to the rim () in order to receive bearings for guiding the wheel in rotation about an axis of rotation (X) on an axle of the aircraft. The wheel includes at least one dog () that projects laterally from the rim in order to present two parallel faces (). The dog is pierced by an orifice () extending from one face to the other along a generally orthoradial direction (Y).
