Protective Crown Reinforcement For Aeroplane Tire

Aircraft tire comprising:

• a tread, configured to come into contact with a ground;
• a protective reinforcement, radially on the inside of the tread;
• the protective reinforcement having a cylindrical structure having as its axis of revolution the axis of rotation of the tire, extending axially from a first axial end as far as a second axial end over an axial width L and extending radially from a radially interior first face as far as a radially exterior second face over a mean radial thickness T;
• the protective reinforcement comprising reinforcers coated in an elastomer compound, having a diameter D and having a path in the circumferential direction of the tire;
• the protective reinforcement being radially on the outside of a working reinforcement;
• the working reinforcement comprising at least two radially superposed working layers made up of reinforcers having a zigzag path in the circumferential direction of the tire;
• wherein the protective reinforcement has a mean radial thickness T at least equal to two times the diameter D of a said reinforcer, wherein the protective reinforcement comprises respectively on its radially interior face and on its radially exterior face parts made of elastomeric compound having an axial width W at least equal to the diameter D of a said reinforcer, wherein the path of any said reinforcer of the protective reinforcement, in the circumferential direction of the tire, varies radially between the radially interior first face and the radially exterior second face, in such a way that the set of paths of said reinforcers of the protective reinforcement constitutes a three-dimensional lattice and wherein the path of any said reinforcer of the protective reinforcement, in the circumferential direction of the tire, is a zigzag curve extending axially over the entire axial width L of the protective reinforcement.
