Rim for a braked aircraft wheel

A braked aircraft wheel comprising a rim which has an outer circular portion whose ends are terminated by flanges for receiving a tire, the outer circular portion being connected by a wheel disk to a hub for fitting on an undercarriage axle in order to rotate about an axis of rotation coinciding with a central axis of the rim, the rim being designed to receive the tire on the outside of the outer circular portion and a brake on the inside of said outer circular portion, the outer circular portion presenting on one side of the wheel disk that is to receive the brake, in a plane containing the central axis of the braked aircraft wheel, a profile that has two slopes forming non-zero angles with the central axis, the two slopes extending as an extension of one another from the wheel disk up to the corresponding flange and flaring towards said corresponding flange, and the inside of the outer circular portion receiving a thermal protection screen which presents a profile identical to the profile of the outer circular portion of the rim, the profile of the thermal protection screen extending parallel to the profile of the rim.

A method for accelerating cooling of a stack of disks of a braked aircraft wheel that comprises a rim having an outer circular portion whose ends are terminated by flanges for receiving a tire, the outer circular portion being connected by a wheel disk to a hub for fitting on an undercarriage axle in order to rotate about an axis of rotation coinciding with a central axis of the rim, the rim being designed to receive the tire on the outside of the outer circular portion and the stack of disks on the inside of said outer circular portion,

• the method comprising the adoption, by the outer circular portion on one side of the wheel disk that receives the stack of disks, of a profile that has, in a plane containing the central axis of the wheel, two slopes forming non-zero angles with the central axis, the two slopes extending as an extension of one another from the wheel disk up to the corresponding flange and flaring towards said corresponding flange, and the inside of the outer circular portion receiving a thermal protection screen which presents a profile identical to the profile of the outer circular portion of the rim, the profile of the thermal protection screen extending parallel to the profile of the rim.
