Disc brake for an aircraft wheel

A disk brake for an aircraft wheel, comprising:

• a plurality of friction discs (20,30;
• 120,130), including rotor discs and stator discs;
• a plurality of braking actuators (14,15,16;
• 114);
• a structure comprising a torsion tube (11;
• 111) on which the plurality of friction discs are fitted, a rear plate (12;
• 112) which is located at one end of the tube, and a support (13;
• 113) for the plurality of braking actuators at another end of the tube, each actuator in the plurality of actuators being activate able in order to selectively apply a pressing force to the plurality of discs;
• wherein the plurality of discs comprise two separate groups, including a first group of friction disks (20,120) which is pressed alone by said actuators for braking operations below a specific braking torque threshold, and a second group (30,130) of friction disks which is pressed alone or in conjunction with the first group of disks by said actuators for braking operations above said torque threshold.
