Description

PATENTKRAV 1. Vinge (108) med en torsionsmæssigt stiv rod (114), en fremadrettet krumning i forhold til en elastisk akse i en indenbords sektion (112) af vingen og en krumning agterefter i en udenbords . sektion (116) af vingen. 2. Rotor (106) til en vindturbine, hvilken rotor har et nav (110) og mindst én vinge (108) med en torsionsmæssigt stiv rod (114), en indenbords sektion (112), og en udenbords sektion (116), hvor den indenbords sektion har en fremadrettet krumning i forhold til en elastisk akse af vingen og den udenbords sektion har en krumning agterefter. 3. Rotor ifølge krav 2, hvor den fremadrettede krumning er effektiv til at modvirke en del af torsionen, der resulterer fra krumningen agterefter. 4. Rotor ifølge krav 3, hvor krumningen fremefter er ved en rod (114) af vingen, og en del af den fremadrettede krumning er effektiv til at neutralisere et pitchmoment opbygget af vingekrumningen længere udenbords. Ξ. Vindturbine (100) omfattende en rotor (106) med et nav (110) og mindst én vinge (108) med en torsionsmæssigt stiv rod (114), en indenbords sektion (112), og en uden bords sektion (116) , hvilken indenbords sektion har en fremadrettet krumning i forhold til en elastisk akse af vingen og den udenbords sektion har en krumning agterefter. 6. Rotor ifølge krav 5, hvor den fremadrettede krumning er effektiv til at modvirke en del af torsionen, der resulterer fra krumningen agterefter. 7. Rotor ifølge krav 6, hvor krumningen fremefter er ved en rod (114) af vingen og en del af krum ningen fremefter er effektiv til at neutralisere et pitchmoment opbygget af vingekrumningen længere udenbords . 8. Fremgangsmåde til fremstilling af en vinge (108) til en vindturbine (100), hvor fremgangsmåden omfatter at: bestemme en vingefacon ved at udvælge krumningsvinkler for elementer af vingen til derved at (a) forøge eller maksimere en induceret vridningsmængde og distributionen af vridningen til derved at skabe en reduktionsbelastning, (b) reducere eller minimere en forøgelse i vingemateriale nødvendigt til at opretholde tip (120) udbøjning, (c) reducere eller minimere negative virkninger på aerodynamikken, og (d) opretholde konstruktionsmæssig integritet, og fabrikere en vinge (108) i overensstemmelse med den fastlagte vingefacon. 9. Fremgangsmåde ifølge krav 8 yderligere omfattende at vælge en karakter og vægtningsfaktorer (a)-(d) i overensstemmelse med den valgte karakter. 10. Fremgangsmåde ifølge krav 9, hvor vingen har en tip (12 0) , og yderligere hvor bestemmelse af vingefaconen yderligere omfatter at pålægge en begrænsning på en position af tippen og på en maksimal krumningsvinkel.
