The invention provides airplane landing gear comprising at least one axle for carrying at least one brake-and-wheel assembly comprising a rim mounted to rotate on the axle and a stack of disks and a support carrying modular electromechanical actuators that are individually removable, the landing gear and the brake-and-wheel assembly being organized in such a manner that each actuator is in at least one of the following configurations:

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

The invention relates to an actuator for an electromechanical brake, the actuator comprising a pusher and a first drive member arranged to move the pusher in register with a stack of disks and to apply a braking pressure to the stack of disks, the actuator including a second drive member comprising a piezoelectric assembly suitable for modulating the braking pressure applied to the stack of disks. According to the invention, the piezoelectric assembly is disposed inside the actuator so as to present an end that is stationary.

Actuator for an electromechanical brake, a brake including such an actuator, a vehicle including at least one such brake, and a method of implementing said actuator

The invention relates to a method of managing a braking system architecture for an airplane fitted with brakes having electromechanical actuators, in which some of the actuators are connected to a battery assembly of the airplane and other actuators are not connected to the battery assembly of the airplane, which method comprises a step of controlling at least one of the actuators that is not connected to the battery assembly to cause it to exert a force equal to a unit holding force, which force is determined independently of any braking demand from the pilot. The invention also provides an architecture specially adapted to implement the method.
