Abstract:
A wheel brake for an aircraft, the brake comprising a support (2) that receives at least one electromechanical actuator (1) fitted with a pusher (8) facing friction elements (3) and movable under drive from an electric motor (6) to apply a braking force selectively against the friction elements. The actuator is non-reversible such that a reaction force applied on the pusher cannot cause the electric motor to turn, and the actuator is associated with elements (30, 31, 32, 33, 34) for selectively switching off an electric power supply to the electric motor, which elements allow power to be delivered to the actuator in normal circumstances, and switch off the power if (a) the measured speed of rotation (wmes) of the electric motor drops below a first predetermined threshold (S1); and (b) the commanded speed of rotation ( ω) of the electric motor drops below a second predetermined threshold (S2).
