Abstract

En vingespiss omfatter et vertikalt element og et monteringselement. Monteringselementet er utformet for å forenkle monteringen av vingespissen på spissen av et vifteblad. Det vertikale elementet er utformet for å strekke seg vertikalt relativt til spissen av viftebladet. Ved å tilføye vingespisser til viftebladene kan man forbedre aerodynamikken til viftebladene og derved øke effektiviteten til en vifte.A wing tip comprises a vertical member and a mounting member. The mounting element is designed to simplify mounting of the wing tip to the tip of a fan blade. The vertical member is designed to extend vertically relative to the tip of the fan blade. Adding wing tips to the fan blades can improve the aerodynamics of the fan blades, thereby increasing the efficiency of a fan.
