ABSTRACT:
An actuation and extension mechanism for aerodynamic high-lift devices such as a wing leading edge slat or a wing trailing edge flap; wherein an aerodynamic panel is connected to one end of an extendible track member that is supported and guided by its other end through rollers fixedly mounted to wing rib structure. The track member incorporates a cable and drum arrangement as part of the extension or retraction mechanism; and this combination of track, cable and drum provides the primary support and drive means for the high-lift device without compromising the structural strength or the stress safety of said combination.
