Abstract

Et rotorblad (10) for et vindkraftanlegg, omfattende en rotorbladkopling for kopling til et nav (12) av rotoren på et vindkraftanlegg, og en bladtupp (13) anbrakt i den motsatte ende av rotorbladet (10). For å tilveiebringe et rotorblad (10) hvor bøyning kan påvises med enkle midler, er minst en elektrisk leder (20, 21, 22, 23, 24, 26) lagt over lengden av rotorbladet (10), hvor den elektriske leder (20, 21, 22, 23, 24, 26) begynner ved rotorbladkoplingen, strekker seg i lengderetningen av rotorbladet og tilbake til rotorbladkoplingen, og at det er tilveiebrakt en detektor (16) som påviser den elektriske motstand i lederen (20, 21, 22, 23, 24, 26) og er koplet til en evalueringsinnretning som evaluerer den elektriske motstand. Med hensyn til dette er oppfinnelsen basert på den erkjennelse at bøyning av rotorbladet hele tiden fører til forlengelse av bærestrukturen, og at slik forlengelse, når den overføres til en elektrisk leder, fører til en forandring i den elektriske motstand i lederen, hvorfra det er mulig å slutte bøyningen av rotorbladet når forandringen i motstand er proporsjonal med forlengelsen av lederen, og den er igjen proporsjonal med bøyningen av rotorbladet.
