The present invention relates to an aeroplane tyre and, in particular, to its protective reinforcement, and has the objective of increasing its resistance to perforation and cutting by foreign objects. According to the invention, the protective reinforcement (3) has a mean radial thickness T at least equal to 2 times the diameter D of a reinforcer (4), comprises, on its radially inner face (31) and on its radially outer face (32), respectively, parts made of an elastomer compound (7) having an axial width W at least equal to the diameter D of a reinforcer (4), and the trajectory of any reinforcer (4), in the circumferential direction (XX'), varies radially between the first radially inner face (31) and the second radially outer face (32), such that the trajectories of the reinforcers (4) of the protective reinforcement (3) together form a three-dimensional lattice. Moreover, the trajectory of any reinforcer (4), in the circumferential direction (XX'), is a zigzag curve extending axially across the entire axial width L of the protective reinforcement (3). |
