Wind power plays a crucial role in supplying cities with renewable energy. Combined with short transport routes, it is essential to establish site-specific small wind turbines in the urban environment. An increasing interest in small, decentralized, vertical-axis wind turbines (VAWT) can be observed here. However, concepts with low visual and auditory effects and economic efficiencies are largely limited. The project part described in this paper enables a specially developed design software tool of rotor geometries optimized for such boundary conditions. By using fiber-reinforced structures in combination with selective laser sintering, it is theoretically possible to economically produce even the smallest quantities of these geometries for a typical service life of wind turbines. The results presented and discussed in this work can serve as a basis for a subsequent feasibility study.
