Abstract: Telescopic actuator comprising an actuator body; a sleeve with a longitudinal axis mounted such as to rotate and extending at least partially into the body, said sleeve being held in axial position in the body by attachment means; a threaded rod mounted such as to slide telescopically in the longitudinal axis inside the sleeve and engaging with the sleeve by means of a helical link; rotating means suitable for rotating the sleeve such as to slide the threaded rod selectively between an extended position and a retracted position; locking means suitable for making the retraction of the helical link irreversible, such that a retraction of the threaded rod caused by a compression load is prevented when such a retraction is not caused by the driving means. Aircraft engine comprising at least one such actuator.

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.

Abstract: The invention relates to an actuation device (1) for moving a movable cover of a thrust reverser. Said actuation device vice 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.

Abstract: The invention concerns an actuating device (1) for moving a mobile cover of a thrust reverser, comprising: an actuator (5) comprising a first element (10), such as a screw, and a second element (12), such as a nut, mounted mobile device relative to the first element (10) such that the rotation of the first element (10) results in a translational movement of the second element (12) relative to the first element (10), and a locking device (31) comprising a rotating part (34) linked in rotation with the first element (10), and a locking part (35) that is mobile relative to the rotating part (34) between a locked position in which the locking part (35) is engaged with the rotating part (34) to prevent the first element (10) from rotating and an unlocked position in which the locking part (35) is disengaged from the rotating part to allow the rotation of the first element (10), and an electromagnet (39) for moving the locking part (35) to the unlocked position.

Abstract: The invention relates to an actuating device (1) for moving a mobile cap of a thrust reverser, comprising: —an actuator comprising a first element (3), such as a screw, and a second element (4), such as a nut, collaborating with the first element in such a way that turning the first element causes the second element to move in a translational movement, —a locking piece (18) rotationally mobile between a locked position in which the locking piece prevents the first element (3) from turning, and an unlocked position in which the locking piece (18) allows the first element (3) to turn, and —an unlocking piece (25) rotationally mobile between an active position in which the unlocking piece (25) urges the locking piece (18) towards the unlocked position and a passive position in which the unlocking piece (25) allows the locking piece (18) to return to the locked position.
