Abstract: An electromechanical actuator includes: an actuator rod housed in an actuator housing; a linear variable differential transformer “LVDT” fixed to the actuator housing; and an anti-rotation component configured to contact the outer surface of said LVDT. The outer surface of the linear variable differential transformer comprises a first anti-rotation surface feature and the anti-rotation component comprises a second anti-rotation surface feature. The first and second anti-rotation features are sized and shaped relative to each other such that, when in contact with each other, they are configured to prevent rotation of the actuator rod in use.

Abstract: The invention relates to an actuation device (1) for moving the movable cowling of a thrust reverser, comprising: an actuator (7) with a first member (12) such as a screw, and a second member (14) such as a nut, wherein the first and second members are capable of engaging such that the rotation of the first member results in a translation of the second member, a locking device (33) including a locking part (34) movable between a locked position for preventing to the rotation of the first member and an unlocked position for enabling the rotation of the first member, and a lock inhibiting device (42) comprising a recess (46) and a ball (47) movable in the recess between a stowed position, in which the ball enables the movement of the locking part, and an inhibition position in which the ball prevents the locking part from returning into the locked position.
