Arrangement of carbon brake disks for an aircraft brake unit and a method of assembling disks in such an arrangement

An arrangement of carbon brake disks for an aircraft brake unit comprising stators coupled to a torsion tube alternating with rotors coupled to the corresponding wheel, with a front lateral stator at one end adjacent to a braking ring fitted with pistons capable of traveling over a predetermined wear stroke, and with a rear lateral stator at the other end, the arrangement being organized in two configurations corresponding to operation over two successive wear strokes of the pistons, a first of the configurations comprising a central group of rotors and stators arranged between the front lateral stator and a rear group comprising at least the rear lateral stator, and the second configuration comprising the same front lateral stator, and the same rotors and stators of the central group, arranged between a supplementary carbon spacer disk that is adjacent to the pistons and coupled to the torsion tube and of a thickness that is less than the wear stroke of the pistons, and a new rear group comprising at least a new rear lateral stator and of a total thickness that is greater than that of the preceding rear group, the sets of carbon disks constituted in this way having, at the beginning of use, substantially the same total length in each of the configurations.
