Aircraft landing gear assembly with electromechanical actuation and aircraft provided with such assembly

An aircraft landing gear assembly, having a device actuating the landing gear from a retracted position to an extended position and vice versa, and a device for locking and releasing in and from said positions, jointed to an aircraft at a respective hinge point, comprising:

• a rotary actuator acting on the landing gear assembly at said hinge point, having a rotary electric motor connected to an actuating arm, for rotation of the landing gear assembly around a respective actuation axis, through a reduction gear group, with an interconnection so that, in case of power supply failure, the actuator is free to rotate dragged by the landing gear assembly by free fall;
• a linear actuator, integral to the landing gear assembly and movable therewith, which constitutes said locking device and which comprises a rotary electric motor and a cam mechanism to transform a rotary motion of the electric motor into an axial motion of a locking pin according to a respective actuation axis, acting in retraction opposed to a spring which determines the extension thereof in a position for locking the landing gear assembly (1), wherein the actuation axes of the rotary actuator and of the linear actuator are parallel, and wherein the rotation axis of the rotary electric motor of the linear actuator coincides with the linear actuation axis of the locking pin.
