Zusammenfassung:A foldable rotor blade includes a hinge element defining two hinge axes arranged in parallel, and two blade segments each coupled to the hinge element for hinging with respect to a respective one of the hinge axes. The rotor blade has an extended condition in which the blade segments are substantially aligned with each other, and a folded condition in which each blade segment is hinged with respect to the hinge element so that the blade segments are substantially parallel to each other. The blade has a cord and the hinge axes are substantially parallel to the chord. The blade segments have upper surfaces which in the folded condition are facing each other, and which in the extended condition are flush with each other and the intermediate hinge element.
