Introduction
The blades are constructed from carbon-fibre reinforced epoxy. Due to this material composition the blades are light, strong and flexible. They have a taperwise form and a slightly twisted chord. The length is 7.8 metre. The blades are mounted by means of mounting plates and bolted to the pitch-shafts. This design has been tested thoroughly both under static and dynamic loads. Inside the blades is a copper wire netting provided which will protect the blades in case of a lightning attack.
