An airfoil for an airborne wind turbine including a main wing adapted for attachment to an electrically conductive tether, a pivotable trailing element positioned behind the main wing, wherein a chord line of the airfoil has a length that is measured from the leading edge of the main wing to a trailing edge of the trailing element, wherein when the main wing and trailing element are positioned in a first flying position, a slot gap exists between a trailing edge of the main wing and the leading edge of the trailing element, wherein the main wing has a thickness that is 15-28% of the length of the chord line; and wherein a spar bulge exists in the main wing such that 15-25% of the overall length of the chord line has a thickness that is 95% or more of a maximum thickness of the main wing.
