1. En vindmøllevinge til en rotor på et vindenergianlæg med en i hovedsagen vandret rotoraksel, idet rotoren omfatter et nav, ud fra hvilket vindmøllevingen strækker sig i en i hovedsagen radial retning, når den er monteret til navet, hvor vindmøllevingen strækker sig i en langsgående retning parallel med en langsgående akse og har en tipende og en rodende, idet vindmøllevingen yderligere omfatter en profileret kontur omfattende en trykside og en sugeside såvel som en forkant og en bagkant med en korde havende en kordelængde strækkende sig derimellem, hvor den profilerede kontur genererer lift, når den rammes af en indkommende luftstrøm, hvor vindmøllevingen yderligere omfatter et første array af udragende strømningsmodulerende elementer tilvejebragt ved konturens bagkant, hvor de udragende strømningsmodulerende elementer rager ud i en retning i hovedsagen væk fra konturens forkant, hvor elementerne kan fungere til at reducere støj genereret fra drift af vingen ved modulering af luftstrømmen ved konturens bagkant, kendetegnet ved, at vindmøllevingen yderligere omfatter i det mindste en fluiduminjektionsindretning, som kan injicere fluidum ind i luftstømmen over vingekonturen for at reducere turbulent kinetisk energi fra luftstrøm ved den profilerde konturs bagkant til yderligere reduktion af støj fra drift af vingen, hvor fluiduminjektionsindretningen omfatter en dyse, der kan injicere fluidum i form af spray eller dråber ind i luftstrømmen over vingekonturen.
2. Vingen ifølge krav 1, hvor fluidummet er valgt til at have en højere viskositet end den indkommende luftstrøm.
3. Vingen ifølge ethvert af kravene 1-2, hvor det i det mindste første array af udragende strømningsmodulerende elementer rager ud i en langsgående retning langs i det mindste en del af vindmøllevingens længde mellem rodenende og tipenden.
4. Vingen ifølge ethvert af kravene 1-3, hvor de udragende elmenter er valgt fra i det mindste en af de følgende: fortandinger, børster, børsteklynger.
5. Vingen ifølge ethvert af de foregående krav, hvor den i det mindste ene fluiduminjektionsindretning er tilvejebragt ved bagkanten mellem hosliggende udragende elementer.
6. Vingen ifølge ethvert af de foregående krav, hvor den i det mindste ene fluiduminjektionsindretning er tilvejbragt ved bagkanten til at injicere fluidum ind i luftstrømmen omkring den profilerede kontur ved en lokation opstrøms fra bagkanten.
7. Vingen ifølge krav 6, hvor den i det mindste ene fluiduminjektionsindretning er positioneret ved en lokation i afstand fra bagkanten, ca. 5-10% af kordelængden fra bagkanten.
8. Vingen ifølge ethvert af de foregående krav, hvor den i det mindste ene fluiduminjektionsindretning kan injicere fluidum ind i luftstrømmen ved en vinkel på ca. 145-175 grader i forhold til den profilerede kontur af vingen i forhold til vingens forkant.
9. Vingen ifølge ethvert af de foregående krav, hvor den profilerede kontur omfatter en i hovedsagen stump bagkant, hvor den i det mindste første array af udragende strømningsmodulerende elementer er tilvejebragt med den stumpe bagkants trykside, og hvor det i det mindste ene fluiduminjektionsindretning er tilvejebragt ved den stumpe bagkants sugeside.
10. Vingen ifølge ethvert af de foregående krav, hvor den i det mindste ene fluiduminjektionsindretning kan bevæges for at tilvejebringe en justerbar fluiduminjektionsretning.
11. Vingen ifølge krav 10, hvor fluiduminjektionens vinkel kan varieres fra en i hovedsagen nedstrømsretning til en i hovedsagen opstrøms retning.
12. Vingen ifølge ethvert af de foregående krav, hvor vingen omfatter et fluidumkommunikationssystem, der kan transportere et fluidum fra en fluidumbeholder til den i det mindste ene fluiduminjektionsindretning.
13. Vingen ifølge krav 12, hvor fluidumkommunikationsindretningen omfatter i det mindste en ventil, der kan regulere strømning af fluidum til den i det mindste ene fluiduminjektionsindretning.
14. Et vindenergianlæg havende i det mindste en vindmøllevinge ifølge ethvert af kravene 1-13.
