Landing Flaps Drive System

actuator with worm gear and ball screw spindle

The picture shows the actuator. At the actuator housing is the fitting for the flexible shaft which then drives the worm gear inside the actuator housing. The worm gear drives the ball screw spindle which then drives the screw nut. At the end of the spindle is a spring loaded snubber stop.

All four actuators are identical. The three different variants (inboard, outboard lefthand, outboard righthand) are created by adapter parts.
