Abstract

A flying object wing has a leading edge and a trailing edge and an upper and a lower surface between the edges. A portion between the leading edge and trailing edge provides an upper surface which has a curved shape. From the leading part of the upper surface towards the mid part of the surface there is a concave shape. The lower surface has a curved shape such that from the leading part of the upper surface towards the mid part of the surface there is a convex shape. A transverse aperture in the surfaces of the wing accommodates a propeller for creating thrust for forward flight. The blades of the propeller turn in a plane transverse to a line between the leading edge and the trailing edge of the surface.
