Abstract: The invention relates to a motorizing device (1) for moving an aircraft (A) provided with a landing device (L) having wheels (W) on the ground, the motorizing device comprising at least one electric motor (2) having an output shaft provided with means for its rotational connection to at least one of the wheels (W) of the landing device for driving said wheel in rotation, and an electronic control unit (3) connected on the one hand to the motor to control it and on the other hand to a control interface (4) from which the aircraft pilot can transmit control signals which the electronic control unit (3) is arranged to transform into motor control signals, characterized in that the control unit is arranged to implement a first control law having determined dynamics to promote an aircraft movement speed and a second control law having dynamics to promote aircraft manoeuvrability.

Abstract: The invention provides an engagement method for engaging a first gear element with a second gear element, at least the second gear element being mounted to move between a meshing position and a disengaged position by means of an actuator. The engagement method including a step of driving at least one of the gear elements in rotation so as to establish a non-zero difference in speed of rotation between said gear elements, and a step of controlling the actuator to perform the following in succession: moving at least the second gear element towards the meshing position; on detecting contact between the gear elements, stopping the movement of the second gear element; and on detecting an ideal angular position for engaging said gear elements, moving the second gear element as quickly as possible into the meshing position.

Abstract: A method for engaging a first gear element with a second gear element is provided. The second gear element is mounted to be mobile between a meshing position and a position of disengagement using an actuator. The method includes driving one or more of the first and second gear elements in rotation to form a non-zero rotation speed difference between the first and second gear elements and controlling the actuator to successively displace the second gear element to the meshing position, and when an intermediate position of the second gear element is detected, stop the displacement of the second gear element, and when an angular position of engagement of the first and second gear elements is detected, displace the second gear element to the meshing position.
