Landing gear, a brake, a brake-and-wheel assembly for an airplane, and a method of maintaining such landing gear

Airplane landing gear comprising at least one axle for carrying at least one brake-and-wheel assembly comprising:

• a wheel having a rim mounted to rotate on the axle,
• a brake including a stack of disks arranged to apply braking torque to the wheel in response to pressure applied to the stack of disks, and a support carrying modular electromechanical actuators that can be removed individually and that extend facing the stack of disks in order to apply pressure in controlled manner to the stack of disks,
• wherein the landing gear and the brake-and-wheel assembly are shaped in such a manner that each actuator is in at least one of the following configurations:
• an empty space of dimensions sufficient for receiving the entire actuator extends on a disassembly path directly facing the actuator when it is in an operating position;
• the actuator is associated with displacement means enabling it to be moved from an operating position to a disassembly position, an empty space of dimensions sufficient to receive the entire actuator extending along a disassembly path directly facing the actuator when it is in the disassembly position, such that each actuator is removable from the support without disturbing the brake-and-wheel assembly.
