FIELD: engines and pumps.
SUBSTANCE: drive of movable element of aircraft engine nacelle includes engine installed on fixed element of nacelle, worm gear type screw provided with possibility of being brought into rotation with that engine, a slide and a shell. Slide is attached to movable element and includes a nut being engaged with work gear type screw and the first hinge allowing angular displacement between axis of worm gear type screw and slide. Shell is made so that it can place work gear type screw and is located inside slide with a gap. Nut is installed on the shell end that is closer to the engine, and the first hinge is inserted between the other shell end and slide. The other invention of the group relates to aircraft engine nacelle containing fixed element, movable element, as well as the above actuator located between fixed and movable elements.
EFFECT: inventions allow reducing mechanical losses acting on worm gear type screw at displacement of slide relative to the engine, simplifying the installation and detachment of movable nacelle element on fixed element.
