Claims (10)

1. Rotorvinge (140) til brug i et vindenergisystem (100), hvor rotorvingen omfatter et rotorvingelegeme (240) omfattende en spids (210) af rotorvingelegemet en kavitet (310) af rotorvingelegemet, og en lynbeskyttelsesenhed, hvor lynbeskyttelsesenheden omfatter en ledende del (400), som er forbundet til en nedledningsindretning (300) og anbragt inde i kaviteten af rotorvingelegemet tæt ved eller ved rotorvingele-gemets spids (210), hvor den ledende del har en forlængelse (450), der rager ud af rotorvingelegemet og er anbragt til optagelse af en receptor.
2. Rotorvinge ifølge krav 1, der yderligere omfatter en receptor (500), som er aftageligt fastgjort til forlængelsen (450) af den ledende del (400).
3. Rotorvinge ifølge krav 2, hvor rotorvingen omfatter en drænkanal (600, 710) inde i receptoren, som er anbragt ved siden af forlængelsen af den ledende del.
4. Rotorvinge ifølge krav 2 eller 3, hvor receptoren omfatter en kavitet (510) til at optage forlængelsen af den ledende del.
5. Rotorvinge ifølge et hvilket som helst af kravene 2-4, hvor receptoren omfatter en boring (710), som er indrettet til at danne en drænkanal (600).
6. Rotorvinge ifølge krav 1, hvor den ledende del omfatter en eller flere boringer {410; 420:430).
7. Vindenergisystem (100) med mindst en, fortrinsvis tre rotorvinger ifølge et hvilket som helst af de foregående krav.
8. Fremgangsmåde til opbygning af en rotorvinge til brug i et vindenergisystem omfattende følgende trin: - at fremstille en tryksideskal og en sugesideskal af rotorvingen, - at påføre en ledende del på en indvendig side af tryksideskallen eller sugeskiveskallen, hvor den ledende del omfatter et legeme og en forlængelse og - at tildanne rotorvingen ved at samle tryksiden og sugesiden med hinanden på en sådan måde, at legemet af den ledende del ligger inden for rotorvingen, og forlængelsen af den ledende del rager ud af rotorvingen.
9. Fremgangsmåde til at opbygge en rotorvinge ifølge krav 8, hvor påføring af den ledende del udføres ved at lime den fast på den indvendige side af tryksideskallen eller sugesideskallen.
10. Fremgangsmåde til at opbygge en rotorvinge ifølge krav 8 eller 9 med det yderligere trin at fiksere en receptor på forlængelsen af den ledende del.
