Description

PATENTKRAV: 1. Vindmøllevinge med en dæmperindretning til modvirkning af opbygning af kantvise egensvingninger af vingen, hvilken dæmperindretning omfatter indbyggede beholdermidler med delvis væskefyldning, og hvilken vinge er beregnet til drift i en vingerotor med kendt, i hovedsagen konstant omdrejningstal, kendetegnet ved, at beholdermidlerne udgør afstemte væskedæmpere (TLD) med frit skvulpelig væske med en bølgefrekvens, som under hensyn til den forventede G-påvirkning af væsken under drift af vingen er afstemt til vingens konstaterede egenfrekvens. 2. Vinge ifølge krav 1, kendetegnet ved at beholdermidlerne forekommer som en aksial række af tværstillede beholdere i en ydre endedel af vingen. 3. Vinge ifølge krav 2, kendetegnet ved at beholderne er udført med ovalt tværsnit for tilstræbt udfyldning af hulrummet i vingen. 4. Vinge ifølge krav 3, kendetegnet ved at beholderne aftager i tværgående længde ud imod vingetippen, og at indfyld-ningshøjden af væsken målt som et væskelag ud mod en på vingen udadvendende sideflade af hver beholder er mindre i de yderste end i de inderste beholdere.
