Claims (12)
16 DK 177305 B1
1. Partialpitchvinge til en vindturbine, hvor vingen omfatter: - en første vingesektion, 5. en anden vingesektion, - et pitchsystem, der sammenkobler den første vingesektion med den anden vingesektion, hvilket pitchsystem kan virke til at dreje den første vingesektion i forhold til den anden vingesektion, hvori der er defineret et mellemrum mellem den første vingesektion og den anden vingesektion ved samlingen mellem første og anden vingesektion, 10 hvori vingen yderligere omfatter mindst et forbindelseselement tilvejebragt ved samlingen, idet det mindst ene forbindelseselement i det væsentlige dækker mellemrummet, kendetegnet ved, at det mindst ene forbindelseselement er udformet sådan, at forbindelseselementets udvendige overflade i det væsentlige flugter med mindst en del af den udvendige overflade af mindst en af vingesektioneme ved samlingen. 15
2. Partialpitchvinge ifølge krav 1, hvori det mindst ene forbindelseselement er udformet til at tilvejebringe en aerodynamisk profil ved samlingen.
3. Partialpitchvinge ifølge ethvert af de foregående krav, hvori pitchsystemet er tilveje-20 bragt ved forkanten af partialpitchvingen, hvori det mindst ene forbindelseselement er tilvejebragt ved bagkanten af partialpitchvingen.
4. Partialpitchvinge ifølge ethvert af de foregående krav, hvori det mindst ene forbindelseselement er udformet sådan, at forbindelseselementet er på linie med den første 25 vingesektions samlingsende og den anden vingesektions samlingsende, når den første vingesektion ikke er drejet i forhold til den anden vingesektion.
5. Partialpitchvinge ifølge ethvert af de foregående krav, hvori partialpitchvingen omfatter et første forbindelseselement tilvejebragt ved den første vingesektions samlings- 30 ende og et andet forbindelseselement tilvejebragt ved den anden vingesektions samlingsende, hvor det første forbindelseselement støder op til det anden forbindelseselement. 17 DK 177305 B1
6. Partialpitchvinge ifølge ethvert af de foregående krav, hvori mindst et af den første og den anden vingesektion omfatter et aerodynamisk formet legeme med en forkant og en bagkant, hvori legemet spidser til mod et forholdsvis smalt forbindelsesafsnit tilstø- 5 dende samlingen for kobling til pitchsystemet, hvilket forbindelsesafsnit er tilvejebragt ved legemets forkant, hvori det mindst ene forbindelseselement er udformet til at tilvejebringe en bagkant ved forbindelsesafsnittet.
7. Partialpitchvinge ifølge ethvert af de foregående krav, hvori det mindst ene forbin- 10 delseselement omfatter en skal anbragt over pitchsystemet.
8. Partialpitchvinge ifølge ethvert af de foregående krav, hvori det mindst ene forbindelseselement er dannet af et i det væsentlige fleksibelt materiale.
9. Partialpitchvinge ifølge ethvert af de foregående krav, hvori forbindelseselementet omfatter et elastisk materiale, idet forbindelseselementet er arrangeret til at deformeres, når det første vingeafsnit er drejet i forhold til det andet vingeafsnit.
10. Partialpitchvindturbine omfattende mindst to partialpitchvinger ifølge ethvert af 20 krav 1-10. DK 177305 B1 1/3 1°-"X 12a \4 16a \ \ 1)V t rirv 1 ' / 12 16 FIG. 1 (Prior Art) 26a 20—·^ 22a 24 ) ^ * / "5 7 22 26 FIG. 2 30 ^ DK 177305 B1 2/3 32a 36 34a I-_i 33 35 ——- ---~y 34
