Embodiment Construction

[0134] like figure 1 The aircraft tire 1 shown in the mid-axis half-section view includes a crown 2 , two sidewalls 3 , and two beads 4 . The carcass reinforcement 5 extends from one bead 4 to the other and consists of two circumferential arrangements 6 and 7 of reinforcing elements. The circumferential arrays 6 and 7 of reinforcing elements are positioned radially in the side wall 3 and consist of aramid or aramid reinforcing elements. The reinforcing elements are arranged parallel to each other and separated by a layer of compound 8 whose properties and modulus depend on its position in the tyre.

[0135] The fixation of the two circumferential arrays 6 and 7 in the bead 3 is effected by circumferentially arrayed reinforcement strands or “strands” 9 arranged axially on both sides of each circumferential array 6 and 7 . Each circumferentially arranged reinforcing strand or strands 9 can be obtained by helically winding one strand. The radial reinforcing elements and the ci...

Abstract

The invention relates to mounted assemblies for aircraft and to the wheels and tires which constitute them. The mounted assemblies for aircraft to which the invention relates are characterized in particular by the combination of an inflation pressure greater than 9 bar and a relative deflection of the tire greater than 30%, the wheel comprising a rim for receiving the tire and more specifically seats receiving the beads of said tire. According to the invention, the rim comprises a drop-centre functionality and is advantageously of monobloc type.

Description

technical field [0001] The present invention relates to aircraft mounted assemblies and the wheels and tires comprising these assemblies. The aircraft mounting assembly to which the invention relates is notably characterized by a combined inflation pressure of greater than 9 bar and a relative tire deformation of greater than 30%. Background technique [0002] Tire deflection is defined by the radial deformation, or change in radial height, of the tire as it changes from an unloaded to a static loaded condition under rated load and pressure conditions. [0003] Tire deflection, expressed as relative deflection, is defined by the ratio of the change in radial height of the tire to half the difference between the outer diameter of the tire and the largest diameter of the rim measured at the retaining ring. Among them, the outer diameter of the tire is measured statically under the rated pressure and non-loaded state. [0004] Reinforcements or reinforcements for tires, espec...
