Abstract

A device which actuates aircraft control surfaces is disclosed. The actuator 19 is disposed entirely within the control surface structure 15. Because the actuator 19 is disposed entirely within the control surface 15, the gap 14 between the wing structural box 13 and control surface 15 may be reduced. Reducing the size of the gap 14 is especially desirable for wings with high aspect ratio, wherein the volume of structural box 13 is at a premium.
