Claims (10)

1. Et vindenergianlæg med et første sæt med mindst en vinge monteret på en aksel, samt mindst et andet sæt med mindst en vinge monteret på samme aksel og monteret således, at vingesættene vil have samme rotationsretning og samme omdrejningstal, hvilket andet sæt vinger har en længde, som er mindre end det første sæt vingers, og hvilket andet sæt vinger har et andet optimalt tiphastighedsforhold end det første sæt vinger, således at to sæt vinger er optimerede med hensyn til effektudbytte ved samme omdrejningstal.
2. Et vindenergianlæg ifølge krav 1, kendetegnet ved, at forholdet mellem længderne af de to sæt vinger er tilnærmelsesvist bestemt ved forholdet mellem de to sæt vingers optimale tiphastighedsforhold.
3. Et vindenergianlæg ifølge krav 1, kendetegnet ved, at det andet sæt vinger er konstrueret til et optimalt tiphastighedsforhold bestemt ud fra forholdet mellem de to sæt vingers længde og det optimale tiphastighedsforhold for det ene sæt vinger.
4. Et vindenergianlæg ifølge et eller flere af kravene 1-3, kendetegnet ved, at de mindst to sæt vinger er placeret lige efter hinanden på deres fælles aksel.
5. Et vindenergianlæg ifølge et eller flere af kravene 1-4, kendetegnet ved, at de mindst to sæt vinger udgør et fælles rotorplan.
6. Et vindenergianlæg ifølge et eller flere af kravene 1-5, kendetegnet ved, at det andet sæt vinger udgør en vindrose og det første sæt vinger udgør en hurtigløber.
7. Et vindenergianlæg ifølge et eller flere af kravene 1-6, kendetegnet ved, at det andet sæt vinger er hængslet monteret således, at de kan drejes om deres længdeakse.
8. Et vindenergianlæg ifølge et eller flere af kravene 1-7, kendetegnet ved, at det andet sæt vinger er monteret således, at de kan bremses uafhængigt af det første sæt vinger.
9. Et vindenergianlæg ifølge et eller flere af kravene 1-8, kendetegnet ved, at det andet sæt vinger er monteret således, at de kan samles radialt i en eller flere grupper.
10. Anvendelse af et vindenergianlæg, som beskrevet ved et eller flere af kravene 1-9.
