Abstract
The invention relates to an actuation device (1) for moving a movable cover of a thrust reverser. Said actuation device includes: —an actuator including a first element (4), such as a screw, and a second element (5), such as a nut, that engages with the first element such that rotation of the first element causes translation of the second element; —a locking portion (31) rotatable between a locked position, wherein the locking portion prevents the first element (4) from rotating, and an unlocked position, wherein the locking portion (31) allows the first element (4) to rotate; and —an inhibiting part (45) that is translatable between a first position, wherein the inhibiting part (45) allows the locking portion (31) to rotate, and a second position, wherein the inhibiting part (45) prevents the locking portion (31) from rotating into the locked position.
