Claims (7)

1. Vindmøllerotorvinge (12) omfattende en roddel (14) og en spidsdel, som strækker sig derfra, hvilken roddel omfatter en flerhed af indsatser (16, 18) indlejret deri, kendetegnet ved, at indsatserne (16,18) strækker sig aksialt ind i rotorvingen (12), hvor hver indsats (16, 18) er konfigureret til at modtage respektive forbindelsesorganer til at forbinde vindmøllerotorvingen (12) med vindmøllenavet, hvor en første indsats (16) har en første længde og en anden indsats (18) har en anden længde, forskellig fra den første længde, hvor hver indsats omfatter et respektivt gevindboring (8), og hvert forbindelsesorgan omfatter en bolt.
2. Rotorvinge ifølge krav 1, hvor roddelen (14) omfatter en tredje indsats med en tredje længde, forskellig fra hver af den første og anden længde.
3. Rotorvinge ifølge krav 2, hvor længderne af indsatserne er i området på 5 til 30 gange en diameter af den respektive boring (8).
4. Rotorvinge ifølge et hvilket som helst af de foregående krav, hvor forskellen mellem længderne af to tilstødende indsatser er i området på 2 % og 50 % af længden af den længere af de to indsatser.
5. Rotorvinge ifølge krav 4, hvor forskellen mellem længderne af to tilstødende indsatser er i området på 5 % til 20 % af længden af den længere af de to indsatser.
6. Rotorvinge ifølge krav 5, hvor hver forbindelsesorgan omfatter en enkelt bolt.
7. Vindmølleinstallation omfattende: et tårn; et nav monteret på tårnet; og en rotorvinge ifølge et hvilket som helst af de foregående krav, forbundet til navet af en flerhed af bolte, hvor hver bolt er placeret i et respektivt hul dannet i navet og modtages en respektiv indsats i rotorvingen.
