<p>The invention relates to the improvement of the removal of heat generated in the working reinforcement of an aircraft tyre, from the hottest points, which are generally located at the ends of the working reinforcing layers, to the least hot points, which are generally located in the central region of the working reinforcement, so as to obtain a more even distribution of temperatures in the crown of the tyre. An aircraft tyre comprises a crown reinforced by a working reinforcement (3), comprising at least one working reinforcing layer (30) made up of strips (31) that run circumferentially overall, are axially juxtaposed, and made up of mutually parallel textile reinforcing elements (32) coated in a polymeric coating material (33). According to the invention, each strip of at least one working reinforcing layer is in contact, over at least its radially inner axial face, with a heat transfer element (34) comprising filamentary elements (35) running circumferentially overall, mutually parallel and made up of a heat conducting material, the thermal conductivity of the heat conducting material of an overall circumferentially-running filamentary element is at least equal to fifty times the thermal conductivity of the polymeric coating material with which the textile reinforcing elements of the strip in contact with the heat transfer element are coated and a heat transfer element (34) comprises overall circumferentially-running filamentary elements (35) exhibiting periodic geometric oscillations parallel to the strip in contact.</p> |
