Validating algorithms for calculation of the shape of a flexible blade

Methods and tools are developed to measure, analyze and compare physical and virtual blade shapes. An application is presented using measured data and the results of two blade shape calculation algorithms. A measuring method has been developed and a set-up for measuring physical blades was built. Tools were implemented to compare and evaluate the calculated and measured shapes. From the analysis of the measured data and the calculated results of the involved algorithms it could be concluded that none of the algorithms used initially could be applied directly for our shape calculations. The developed tools and methods have been found useful for the adaptation and fine-tuning of the algorithms, which is demonstrated in two examples.
