Stringent Demands for Boosting the Efficiency of Wind Power Plants
Further development of wind power plants and their components with the aim of boosting the useful energy is a very dynamic process. One essential factor is the optimization of the rotor blades, a factor, which has substantial impact on the functionality and efficiency of the plants. A rotor blade length of 38 m has now been reached (Figure 1). In future, lengths of approx. 80 m are to be implemented on the planned offshore plants. These ever-increasing sizes and the requirement for mass production of the rotor blades, which are designed on the basis of aerodynamic principles, true-to-detail, necessitate a quality assurance system whose performance and efficiency must be adjusted constantly.
