<p>The invention relates to a rotor blade for a wind power plant provided with several holes which are embodied in the base thereof and designed in the form of passage holes extending essentially vertically with respect to the longitudinal axis of said rotor blade which also comprises transversal bolts inserted into said holes and strength members connectable to the transversal bolts. Usually, the strength members extend in the base of a rotor blade thereby weakening material in said area. The aim of said invention is to solve the problem by simplifying the structure. For this purpose, the inventive rotor blade is characterised in that the strength members extends outwards the rotor blade base in such a way that said area is aerodynamically modified in a disadvantageous manner at a hub area without detrimentally affecting the acoustic behaviour and other properties of the device since the blade base is covered by a blade spinner or arranged at least in the low-rotating rotor area.</p> |
