Abstract: Foldable raked wing tips having aerodynamic devices are disclosed. A disclosed example wing for use with an aircraft includes a fixed portion, and a folding portion proximate a distal end of the wing. The folding portion includes a raked surface. The wing also includes at least one of a feather or a winglet, and a hinge operatively coupled between the fixed and folding portions to enable the folding portion to fold relative to the fixed portion.

Abstract: Wingtip feathers, including paired, fixed features, and associated systems and methods are disclosed. A method for designing an aircraft wing in accordance with a particular embodiment includes providing a geometry for a wing having an upper surface, a lower surface, and an aft-swept wing leading edge. The method can further include selecting a geometry and location for a first feather and a second feather, based at least in part on a predicted effect of the feathers on a location of a shock at the upper surface of the wing at transonic flight conditions, with the first feather being positioned at an outboard tip of the wing and the second feather being positioned at the outboard tip of the wing aft of the first feather.
