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.
