Master thesis on tip-split wind turbine blades

To achieve the goals set in the Paris agreement, it is required to replace fossil energy by renewable energy. One source of renewable energy, also used extensively at the start of the industrial revolution, is the wind. The cost of wind energy might be reduced by building split wind turbine blades. In this thesis, three main subjects related to the alignment of the wind turbine blade sections were reviewed: The first is the alignment process itself, to determine with what accuracy the parts of a tip-split wind turbine can be aligned. The second is the impact of angular alignment deviations on the aerodynamics. And the third subject is the variation in profile thickness due to different blade production processes. Knowing this variation is required for calculating the joint strength. For each of these subjects the result are promising with respect to the practical feasibility of tip-split wind turbine blades.
