Abstract
A method of transporting and storing a wind turbine blade includes providing a wind turbine blade including a blade root having a longitudinal central axis and a blade tip. The wind turbine blade curves in an unloaded state in such a manner that the blade presents a substantially concave face and a substantially convex face, and such that the blade tip is spaced apart from the longitudinal central axis of the blade root. The wind turbine blade is prestressed at a distance from the blade root in such a manner that the blade tip is brought closer to the longitudinal central axis of the blade root.
