an edge morphing arrangement for an airfoil having upper and lower control surfaces is provided with an elongated edge portion that overlies the edge of the airfoil , the edge portion having a surface element having first and second edges that communicate with , and form extensions of , respective ones of the upper and lower control surfaces of the elongated airfoil . the surface elements are formed of deformable compliant material that extends cross - sectionally from the first surface element edge to an apex of the edge portion , and to the second surface element edge . there is additionally provided a driving link having first and second driving link ends , the first driving link end being coupled to the interior of one of the first and second rib portions . the second end is arranged to receive a morphing force , and the rib element is deformed in response to the morphing force .
