Claims (14)

1. Vindturbinerotorvinge (1) med en overside (13), en underside (14), en forkant (16), en bagkant (15), et navfastgørelsesmiddel (17) og en vingespids (12), hvori vindturbinerotorvingen (1) er opdelt i et navområde (111), et mellemområde (112) og et vingespidsområde (113), og et rodområde (11) er defineret fra navfastgørelsesmidlet (17) til den maksimale bladdybde (Smax), hvori - der inde i vindturbinerotorvingen (1) er tilvejebragt en radielt udad forløbende luftledekanal (23) til at lede indsuget luft fra et sugeområde (21) til et udblæsningsområde (22) arrangeret i vingespidsområdet (113), og hvor en grænselagssugning forekommer, hvor indsugning af luft forekommer på oversiden af vindturbinerotorvingen (1), - og hvor der er tilvejebragt et grænselagshegn (28) i navområdet (111) nær ved navfastgørelsesmidlet (17) for at hindre en strømning i retning af navfastgørelsesmidlet (17), hvori - bagkanten (15) i navområdet (111) i det mindste i det første afsnit af det tilstødende mellemområde (112) er stump, bred og/eller afskåret og aftager i retning af vingespidsområdet (113), kendetegnet ved, at bagkanten er videreført forbi rodområdet (11) i retning af vingespidsen (12), sugeområdet (21) er arrangeret i det område, hvor en laminar luftstrøm løsrives fra oversiden (13) på måde, der er specifik for rotorvingegeometrien, sådan at der forekommer kontakt og videreførelse af den laminare luftstrøm mod den yderligere overflade af oversiden (13), og - sugeområdet (21), begyndende ved eller nær ved grænselagshegnet (28) i navområdet (111), strækker sig ind i mellemområdet (112), hvori sugeområdet (21) fortsætter i mellemområdet (112) forbi rodområdet (11) i retning af vingespidsen (12).
