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.
