Claims (9)
1. Rotornav (1) til en vindmølle, udformet til at støtte eller støtte mindst en rotorvinge, hvor rotornavet (1) omfatter et basiselement (2) med en første sektion (4), der tilvejebringer et forbindelsessted, der kan forbindes med en vindmøllestruktur, og en overfor liggende sektion (5), der tilvejebringer en frit eksponeret frontdel (6), kendetegnet ved, at frontdelen (6) i det mindste delvist er opbygget af en sandwich-konstruktion.
2. Rotornav ifølge krav 1, hvor sandwich-konstruktionen omfatter mindst to over for hinanden liggende afstivningslag (7a, 7b) og mindst et mellemliggende lag (8), der er anbragt imellem afstivningslagene (7a, 7b).
3. Rotornav ifølge krav 2, hvor afstivningslagene (7a, 7b) er fremstillet af metal, især jernbaseret metal, og/eller kompositmateriale, især fiberforstærket plastmateriale.
4. Rotornav ifølge krav 2 eller 3, hvor det mellemliggende lag (8) er fremstillet af plast- eller kompositmateriale, især fiberforstærket plastmateriale.
5. Rotornav ifølge et af kravene 2 - 4, hvor det mellemliggende lag (8) omfatter et mellemliggende lagelement, som har en kamlignende og/eller celleformet struktur.
6. Rotornav ifølge et af kravene 2 - 5, hvor det mellemliggende lag (8) er fastgjort til afstivningslagene (7a, 7b).
7. Rotornav ifølge krav 6, hvor fastgørelsen af det mellemliggende lag (8) er tilvejebragt ved hjælp af mindst et bindemiddel, fortrinsvis et klæbemiddel, og/eller ved svejsning og/eller lodning.
8. Rotornav ifølge et af de foregående krav, hvor frontdelen (6) er fastgjort til mindst en flangelignende del (9a, 9b) forsynet med basiselementet (2).
9. Vindmølle, især vindmølle med direkte drev, omfattende mindst et rotornav (1) ifølge et af de foregående krav.
