ABSTRACT:
A rotor blade, for example for a windmill, comprises a plurality of blade ctions between a blade root and a tip. The sections are interconnected by tensioning members such as steel cables or the like, preferably extending through the blade sections. Thus, each section may be manufactured individually and all components may be assembled at the construction site, whereby relatively large windmill rotors may be constructed.
