Learjet Inc.'s Learjet 31 and Learjet 55C both feature NASA developed winglets, nearly vertical extensions of the wing designed to reduce fuel consumption and generally improve airplane's performance. Winglets are lifting surfaces designed to operate in the vortex or air whirlpool that occurs at an airplanes wingtip. This complex flow of air creates air drag; the winglets job is to reduce the strength of the vortex and thereby substantially reduce drag, additionally the winglet generates its own lift producing forward thrust in the manner of a sailboat's sail. Combination of reduced drag and additional thrust adds up to improvement in fuel efficiency.
