Claims (4)
1. Vindmøllevinge med højopdriftsanordninger, kendetegnet ved, at omfatte mindst en højopdriftsanordning (2), der er integreret ved en forkant af vingeroden for at muliggøre relativ bevægelse mellem højopdriftsanordningen og vingeroden, og en højopdriftsanordning (1), der er integreret ved en bagkant af vingeroden og tilvejebringer kontinuitet med en overflade af vingen, hvor højopdriftsanordningen ved bagkanten haren stump bagkant og en kordelængde (C).
2. Vindmøllevinge med højopdriftsanordninger ifølge krav 1, kendetegnet ved, at højopdriftsanordningen (2) ved forkanten er udvalgt fra gruppen bestående af: (i) en første højopdriftsanordning ved forkanten (20), der har en kontaktflade med vingeroden (4) og en udvendig overflade med en let krumning; (ii) en anden højopdriftsanordning ved forkanten (21), der haren kontaktflade med vingeroden (4) og en udvendig overflade med et vendepunkt; (iii) en tredje højopdriftsanordning ved forkanten (22), der har en kontaktflade med vingeroden (4) og med en udtalt udvendig profil, der har en overflade uden vendepunkter; (iv) en fjerde højopdriftsanordning ved forkanten (23), der har en minimumskontaktflade med vingeroden (4) og en udvendig overflade med et udtalt vendepunkt.
3. Vindmøllevinge med højopdriftsanordning ifølge krav 1, kendetegnet ved, at højopdriftsanordningen ved bagkanten (1) har en tykkelse, der er valgt, således at højopdriftsanordningen ved bagkanten (1) har samme opdriftskoefficient som en højopdriftsanordning, der er tyndere, og den har en kordelængde, der er 5 % til 30 % større end kordelængden (C).
4. Vindmøllevinge med højopdriftsanordninger ifølge krav 1, kendetegnet ved, at højopdriftsanordningen ved bagkanten (1) er integreret med vingeroden (4) for at tilvejebringe kontinuitet mellem højopdriftsanordningen ved bagkanten (1), vingeroden (4) og overfladen på vingen (3).
