Claims (10)

1. Bladsæt til en rotor, kendetegnet ved at omfatte mindst et indre stykke (202), et ydre stykke (204) og en samling (206), som er konfigureret til at samle det indre stykke og det ydre stykke, hvor bladsættet er konfigureret til at tilvejebringe passiv last-reduktion, når det samles (108).
2. Bladsæt ifølge krav 1, hvor det ydre stykke er pileformet bagud.
3. Bladsæt ifølge krav 1 eller 2, hvor bladsættet, når det er samlet, omfatter en spids (208), og hvor en indre del af det samlede blad tilvejebringer et vridningsmoment, som virker i en modsat retning i forhold til et vridningsmoment ved bladspidsen, når det samlede blad er monteret på en rotor (106).
4. Bladsæt ifølge et af de foregående krav, hvor det indre stykke, når bladsættet er samlet til et blad, omfatter nævnte indadgående del, og hvor det ydre stykke omfatter bladspidsen (208).
5. Bladsæt ifølge et af de foregående krav yderligere omfattende et kardanrør (300) med en vridningsstivhed valgt til at opnå eller approximere en målstigningsværdi.
6. Vindturbine (100), kendetegnet ved at omfatte: et tårn (104); en generator (102) på tårnet, hvor generatoren omfatter en rotor (106) med mindst ét samlet blad (108) omfattende mindst et indre stykke (202), et ydre stykke (204) og en samling (206), som er konfigureret til at samle og adskille det indre stykke og det ydre stykke, hvor det ydre stykke er konfigureret til at tilvejebringe passiv last-reduktion.
7. Vindturbine ifølge krav 6, hvor det ydre stykke er pileformet bagud.
8. Vindturbine ifølge krav 6 eller 7, hvor bladet omfatter en spids (208), og hvor en indre del af bladet tilvejebringer et vridningsmoment, som virker i modsat retning i forhold til et vridningsmoment ved bladspidsen.
9. Vindturbine ifølge krav 6, 7 eller 8, hvor det ydre stykke er pileformet bagud, og hvor det indre stykke er pileformet fremad for at tilvejebringe et vridningsmoment, der virker i en modsat retning i forhold til dét af det ydre stykke, for at afbalancere en vridningslast af bladet.
10. Fremgangsmåde til at samle et rotorblad (108) på en rotor (106) af en vindturbine (100), hvor fremgangsmåden erkendetegnet ved at omfatte: at transportere mindst to usamlede stykker (202, 204) af et blad, hvor stykkerne indbefatter en ydre bladdel (204) med en bagud-gående pileform og en indre bladdel (202); og at samle mindst den ydre bladdel og den indre bladdel til et blad og på rotoren af vindturbinen.
