1979 Winglets

Wingtip devices or winglets are usually intended to improve the efficiency of fixed-wing aircraft.The concept of winglets originated in the late 19th century, but the idea remained on the drawing board.Throughout the 1970s when the price of aviation fuel started spiraling upward, NASA aeronautical engineer Richard Whitcomb began investigating and studying the feasibility of winglets in order to improve overall aerodynamics and reduce drag on aircraft.
