Claims (12)

1. Vinge (24) til en vindmølle (10), hvilken vinge omfatter et legeme (28), som er tilpasset til bevægelse som reaktion på en vindstrømning forbi vingelegemet (28), hvilket legeme (28) omfatter - en indvendig flade (42), som definerer et indre kammer (44); og - en modstående udvendig flade, kendetegnet ved, at legemet (28) yderligere omfatter - en indvendig skin (38), som definerer den indvendige flade (42); - en udvendig skin (34) og en - luftspalte (48), som er defineret mellem den indvendige skin (38) og den udvendige skin (34); og - mindst et dæmpningselement (50), som er koblet til og strækker sig fra den indvendige flade (42) af legemet (28), hvor det i det mindste ene dæmpningselement (50) er udformet til at fremme reduktionen af en mængde af støj, der fremkaldes af vingen og breder sig igennem den.
2. Vinge (24) ifølge krav 1, hvor legemet (28) omfatter en indenbordssektion, en udenbordssektion og en midtersektion, der strækker sig mellem indenbords- og udenbordssektionen, og hvor det i det mindste ene dæmpningselement (50) er anbragt i mindst en af indenbordssektionen eller udenbordssektionen.
3. Vinge (24) ifølge krav 2, hvor det i det mindste ene dæmpningselement (50) er koblet inden i indenbordssektionen af legemet (28).
4. Vinge (24) ifølge krav 2, hvor det i det mindste ene dæmpningselement (50) er koblet inden i udenbordssektionen af legemet (28).
5. Vinge (24) ifølge et af de foregående krav, hvor det i det mindste ene dæmpningselement (50) omfatter mindst en bulkhead (54).
6. Vinge (24) ifølge krav 5, hvor den i det mindste ene bulkhead (54) og mindst en del af den indvendige flade (42) af legemet (28) er dækket med et akustisk dæmpningsmateriale.
7. Vinge (24) ifølge krav 6, hvor det akustiske dæmpningsmateriale er udvalgt fra en gruppe af materialer bestående af gummi, skum, mineraluld, ekspansionsskum, fiberglas, filt og kaolinuld.
8. Vinge (24) ifølge krav 6 eller 7, hvor det akustiske dæmpningsmateriale har en konisk form.
9. Vinge (24) ifølge et af kravene 5-8, hvor den i det mindste ene bulkhead (54) omfatter en støddæmper (80’, 80”).
10. Vinge (24) ifølge et af de foregående krav, hvor vingen (24) yderligere omfatter en forkant (70) og en bagkant (72), hvor det i det mindste ene dæmpningselement (50) strækker sig i det væsentlige i længderetningen inden i legemet (28) tilstødende til bagkanten (72).
11. Vinge (24) ifølge krav 10, hvor dæmpningselementet (50) er anbragt i det ydre 20-50% fra bagkanten (72).
12. Vinge (24) ifølge et af de foregående krav, hvor luftspalten (48) er defineret inden i en del af et kernemateriale (36), hvilket kernemateriale (36) befinder sig mellem den udvendige skin (34) og den indvendige skin (38).
