Abstract: An aircraft wing having a relatively thin airfoil cross section including a main body portion and a plurality of auxiliary airfoil sections disposed at the trailing edge of the wing and movable relative to the main body portion and to one another. In a normal cruise position the auxiliary sections and the main body portion form a complete airfoil having a substantially contiguous and unbroken exterior airfoil surface which preserves the high speed characteristics of the wing. At least two of the auxiliary sections comprising a leading auxiliary section and a trailing auxiliary section are movable about a common hinge member carried by the main body portion, while another auxiliary section also hingedly connected to the main body portion is positioned relative thereto in response to the position of the other auxiliary sections.
