Abstract

En sirkulerende innretning omfattende en vifte med stor diameter og forsterkede vifteblad med en avskrånet bæreflateform. Viftebladene kan være formet ved å bruke en ekstruderingsfremgangsmåte hvor hvert vifteblad kan omfatte en forsterket bakre kant med en nedoverragende flens. Fordelen med å forme hvert vifteblad med en forsterket bakre kant ifølge oppfinnelsen fører til forbedrede strukturegenskaper, slik at den bakre kant av hvert vifteblad kan fremstilles lenger for å forbedre den aerodynamiske ytelse. Også den forsterkede, bakre kant motstår rivning som kan oppstå under ekstrudering, ved å tilføye det bøyde flensede området til minst en distal ende av den bakre kant. F.eks. vil den bøyde del av den bakre kant føre til stivhet av det ekstruderte materialet i en stabilisert posisjon under formasjonen. Også den bøyde del gir ekstra styrke ved å tilveiebringe støttende krefter i to dimensjoner som er relativt parallelle og vinkelrett på dens lengde for å nøytralisere de negative virkninger av trykkrefter som virker på den bakre kant av viftebladet under ekstruderingen.
