Wings

Wing Wing Appendage used for flight This article is about the term in aerodynamics. For other uses, see Wing (disambiguation) and Wings (disambiguation). A wing is a type of fin that produces both lift and drag while moving through air. Wings are defined by two shape characteristics, an airfoil section and a planform. Wing efficiency is expressed as lift-to-drag ratio, which compares the benefit of lift with the air resistance of a given wing shape, as it flies. Aerodynamics is the study of wing performance in air. Two different planforms are shown with a swept wing KC-10 Extender (top) refueling a diamond-like delta wing F-22 Raptor Equivalent foils that move through water are found on hydrofoil power vessels and foiling…
