The present invention concerns an aircraft tyre and, in particular, the protective reinforcement of same, and has the aim of increasing the resistance of same to puncturing and cutting by foreign objects. According to the invention, the protective reinforcement (3) has an average radial thickness T at least equal to twice the diameter D of a reinforcement (4), comprises respectively on the radially inner face (31) of same and on the radially outer face (32) of same parts made from an elastomer mixture (7) having an axial width W at least equal to the diameter D of a reinforcement (4) and the path of any reinforcement (4), in the circumferential direction (XX'), varies radially between the first radially inner face (31) and the second radially outer face (32), in such a way that the set of paths of the reinforcements (4) of the protective reinforcement (3) constitutes a three dimensional lattice. Moreover, the protective reinforcement (3) comprises a first family of reinforcements (41) each having a path, in the circumferential direction (XX'), contained in a circumferential plane (XZ) and a second family of reinforcements (42) each having a path, in the circumferential direction (XX'), in a zigzag curve. |
