Claims (8)

1. Rotorblad til et vindenergianlæg og bestående af et oprindeligt rotorblad (2) og en dermed forbundet bladspids-forlængelse (6), hvorved bladspids-forlængelsen (6) udgøres af to glasfiberforstærkede halvskaller (3a, 3b), som er klæbet sammen med hinanden og klæbet til et endeområde på det oprindelige rotorblad (2), hvorved der i området af en bladspids (4) på det oprindelige rotorblad - i hovedsagen vinkelret på bladets længdeakse - er indrettet en ribbe (10) mellem halvskallerne (3a, 3b), hvorved ribben (10) er forsynet med et centralt udsnit (28) til optagelse af bladspidsen (4) på det oprindelige rotorblad (2), hvilket udsnit er tilpasset bladspidsens (4) form.
2. Rotorblad ifølge krav 1, kendetegnet ved, at der fra ribben (10) og i retning mod en spids (8) på bladspids-forlængelsen (6) findes mindst et forstærkningssteg (26).
3. Rotorblad ifølge krav 2, kendetegnet ved, at der er indrettet to forstærkningssteg (26) parallelt med hinanden.
4. Rotorblad ifølge krav 1, kendetegnet ved, at hvert forstærkningssteg (26) har en skumkerne og fire klæbende vinkeldele (30).
5. Rotorblad ifølge et af kravene 2 til 4, kendetegnet ved, at forstærkningsstegene (26) er forbundet med halvskallerne (3a, 3b) ved hjælp af en blindfor-klæbning (34).
6. Rotorblad ifølge et af de foregående krav, kendetegnet ved, at hver halvskal (3a, 3b) er forsynet med nogle parallelt med bladets længdeakse (z) forløbende og udvendigt anbragte forstærkningsbånd (20).
7. Rotorblad ifølge et af de foregående krav, kendetegnet ved, at bladspidsforlængelsen (6) er forsynet med et dræneringshul (40).
8. Rotorblad ifølge et af de foregående krav, kendetegnet ved, at bladspidsforlængelsen (6) er forsynet med en lyn-”modtagelsesdel” (38), som er forbundet med en lynafleder på det oprindelige rotorblad (2).
