Claims (15)

1. Rotorvinge til en vindmølle, hvilken rotorvinge omfatter: et legeme (28), der strækker sig mellem en vingerod (24) og en vingespids (26),hvilket legeme (28) omfatter en trykside (32) og en sugeside (34), der strækker sigmellem en forkant (36) og en bagkant (38); og en dyse (100, 302), der er monteret på eller i legemet (28), hvilken dyse (100,302) omfatter en indgang (106, 206, 306), en udgang (108, 208, 308) og etkonvergerende afsnit (110, 210, 310) mellem indgangen og udgangen, hvilketkonvergerende afsnit er udformet til at accelerere en luftstrøm gennem dysen, således atder genereres en ultralydsemission.
2. Rotorvinge ifølge krav 1, hvor dysen (100, 302) er monteret på en udvendigoverflade (102) af legemet (28).
3. Rotorvinge ifølge krav 2, hvor dysen (100, 302) er monteret på legemet (28)ved eller ved siden af vingespidsen (26).
4. Rotorvinge ifølge krav 2 eller 3, hvor dysen (100, 302) er monteret på legemet(28), således at indgangen (106,206, 306) er anbragt ved eller ved siden af forkanten(36).
5. Rotorvinge ifølge et af kravene 1 til 4, hvor et forhold mellem indgangens(106, 206, 306) tværsnitsområde og udgangens (108, 208, 308) tværsnitsområde har endiameter i området fra ca. 3:1 til ca. 100:1.
6. Rotorvinge ifølge et af kravene 1 til 5, hvor udgangen (108, 208, 308) har endiameter i området fra ca. 1 mm til ca. 15 mm.
7. Rotorvinge ifølge et af kravene 1 til 6, hvor dysen (100, 302) endvidereomfatter et divergerende afsnit (216) nedstrøms for det konvergerende afsnit (210, 310), hvor en dyse indsnævring (218) er defineret mellem det konvergerende og divergerendeafsnit.
8. Rotorvinge ifølge et af kravene 3 til 7, hvor dysen (100, 302) er monteret ilegemet (28), således at udgangen (108, 208, 308) strækker sig gennem legemet (28),hvor indgangen (106, 206, 306) er strømningsforbundet med en tryksat fluidkilde (140).
9. Rotorvinge ifølge krav 8, hvor udgangen (108, 208, 308) strækker sig gennemlegemet (28) ved bagkanten (38).

11. Rotorvinge ifølge krav 10, hvor røret (304) med lukket ende er forbundetmed en udvendig overflade (102) af legemet (28).
12. Rotorvinge ifølge krav 10 eller 11, hvor røret (304) med lukket ende eranbragt nedstrøms for bagkanten (38).
13. Rotorvinge ifølge et af kravene 1 til 12, hvor udgangen (108, 208, 308) erdysens (100, 302) eneste udgang.
14. Vindmølle, der omfatter: et tårn (12); en nacelle (16), der er monteret oven på tårnet (12); en rotor (18), der er forbundet med nacellen (16), hvor rotoren (18) omfatter etnav (20) og mindst en rotorvinge, der strækker sig udad fra navet; og en rotorvinge (22) ifølge et af kravene 1 til 13.
15. Fremgangsmåde til generering af en ultralydsemission fra en rotorvinge (22)af en vindmølle (10), hvilken fremgangsmåde omfatter: at rotere rotorvingen (22), således at en luftstrøm rettes gennem en dyse (100,302), der er monteret på en udvendig overflade (102) af rotorvingen (22), hvor dysen(100, 302) omfatter en indgang (106, 206, 306), en udgang (108, 208, 308) og etkonvergerende afsnit (110, 210, 310) mellem indgangen og udgangen; og at accelerere luftstrømmen gennem det konvergerende afsnit (110,210, 310),således at der genereres en ultralydsemission.
