Besonderer Kastensandwich f r die gewichtsoptimierte, innovative Aussteifung großer WKA-Rotorblätter

At given tip speeds higher performance wind turbines require larger, longer rotor blades. Lengthening of rotor blades will increase their volume content more than their shell surface area. In spite of higher blade loads the potential from the greater volume should provide for specific weight reductions. Practically, however, larger wind turbines are known to be associated rather with specific overweights which in turn could be the cause of operative and life problems. Uncertainties in the kind of present rotor blade stiffening may also be responsible for such overweights.
