ABSTRACT:
Flap carriers fold spanwise (about chordwise axes) into the wing but are moved down together through pivotal linkage; the flaps are protracted and retracted through pivoting of the carriers relative to each other on spanwise axes. On retraction, the entire assembly fits into the wing so that the flow determining contour thereof remains undisturbed.
