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.

The present invention relates to an electromechanical motor (M) provided with an actuator (A) having an outer casing (--) surrounding a stator (-) possessing a coil (). The rotor () is also disposed inside the stator (-). The invention is remarkable in that the actuator has two distinct and independent outlets (S, S) capable respectively of actuating, one after the other, first and second transmissions (C, C).

A torque limiter is provided with a first plate that rotates a second plate via a plurality of balls. The second plate shares the same axis as the first plate. Each ball is suitable for escaping from a respective housing in order to cease driving the second plate when the torque exceeds a predetermined threshold. Each housing includes a first orifice and a second orifice facing each other and formed respectively in the first plate and in the second plate. The torque limiter is remarkable in that it includes first and second distinct inlets for causing the first plate to turn about its axis.

A device for locking a holding structure for securing a foldable blade of a rotorcraft rotor to the hub of the rotor. The holding structure is hinged in pitch and in drag relative to the hub and the rotor includes, for the purpose of folding the blade, elements for locking the blade-holding structure in pitch and in drag, which device is remarkable in that the associated drive elements includes brake elements preventing it from turning in flight, in particular under the effect of vibration from the rotor.

An antivibration device for reducing the vibration of a structure, includes a stationary casing, mounted on the structure, and first and second sets each including two contra-rotary rotors having eccentric flyweights, the flyweights and the rotors being disposed respectively in first and second mutually parallel planes, the centers of rotation of the contra-rotary rotors representing the corners of a rectangular parallelogram in the second plane, and the axes of rotation of the contra-rotary rotors being mutually parallel and orthogonal to the first plane. In addition, it includes a stationary main motor secured to the casing with a through shaft having a first end driving the contra-rotary rotors of the first set and a second end driving the contra-rotary rotors of the second set.
