Crown reinforcement for an aircraft tire

An aircraft tire comprising:

• a working reinforcement radially on an inside of a tread and radially on an outside of a carcass reinforcement;
• the working reinforcement comprising at least two working bi-plies which are radially superposed and respectively have an axial width, from a first axial end to a second axial end;
• each said working bi-ply having a main section comprising at least in part two working layers that are radially superposed, a first, radially outer, one of the at least two working bi-plies comprising, at an axial end thereof, a first axial-end additional thickness, extending axially to an outside of the main section of the first bi-ply, the first axial-end additional thickness comprising a first set of two additional working layers sandwiched between the two working layers of the first bi-ply such that the first axial-end additional thickness is four superposed working layers, each working layer being respectively made up of an axial juxtaposition of portions of a strip, and a second, radially inner, one of the two working bi-plies comprising, at an axial end thereof, a second axial-end additional thickness, extending axially to an outside of the main section of the second bi-ply, the second axial-end additional thickness comprising a second set of two additional working layers sandwiched between the two working layers of the second bi-ply,
• wherein the working reinforcement comprises six working layers only in a region of axial overlap between the first axial-end additional thickness and the main section of the second, radially inner, bi-ply;
• the strip, of axial width W, extending circumferentially in a periodic curve that forms, in the equatorial plane of the tire and with the circumferential direction of the tire, a non-zero angle A and has a radius of curvature R at its extrema;
• the strip being made up of reinforcers coated in an elastomeric compound;
• wherein a difference DL between the respective axial widths of the at least two radially superposed working bi-plies is at least equal to 2×(W+(R−W/2)×(1−cos A)),
• wherein the first, radially outer, one of the at least two working bi-plies contacts the second, radially inner, one of the at least two working bi-plies, over their respective axial widths axially inwardly of the first axial-end additional thickness, and the first and second axial-end additional thicknesses are axially offset by a distance of DL/2.
