An attachable airfoil for use on an airborne vehicle or payload having a plurality of joined, nestable sections which can expand from a collapsed, streamlined position adjacent the vehicle or payload to a fully extended airfoil configuration. In addition, the airfoil incorporates therein a movable control surface which by appropriate remote actuation can be utilized to provide controlled flight of the airborne vehicle or payload.

An attachable, self contained, expandable air foil for use with an airborne body comprising: a longitudinally extending mount, said mount being capable of removable attachment to the outer surface of said airborne body; means connected at one end thereof to said mount for expanding into an airfoil configuration, said airfoil configured means including a plurality of telescopic sections, each of said telescopic sections being of decreasing size in a transverse direction away from said longitudinally extending mount and capable of being nested within one another in a retracted position adjacent said mount and expandable from said mount to a fully extended position in said direction transverse to said longitudinally extending mount; means operably connected between the other end of said airfoil configured means and said mount for providing a movable control surface for said airfoil configured means in order to control the flight of said airborne vehicle; means operably connected between said expandable airfoil configured means and said mount for extending said airfoil configured means from said retracted position adjacent said mount to said fully extended position; and means operably connected to said movable control surface means for providing controlled movement of said control surface means relative to said airfoil configured means only when said airfoil configured means is in its fully extended position.
