Abstract

Fremgangsmåte ved fremstilling av en bladrot på et vindturbinblad og et vindturbinblad (1) som har et aerodynamisk utformet bladparti (2) og en bladrot (3) tilpasset for frigjørbart feste til et nav på en vindturbin, der bladroten er av laminert konstruksjon og omfatter et antall fullstendig heftede bøssinger (4) som forløper stort sett i lengderetningen av bladet (1), hvilke bøssinger (4) er forsynt med en innvendig gjenge (5) for monteringsbolter for frigjørbart feste til navet, der bøssingene (4) omfatter en første del (6) og en forlengelsesdel (7) som har gradvis øket fleksibilitet i retningen bort fra den første delen (6) for å tilveiebringe et lett blad av høy styrke.
