Aerodynamic Design of Wind Turbine Blades Considering Manufacturing Constraints

The present paper investigates the aerodynamic design of wind turbine blades while considering manufacturing constraints. Blade topologies achieved by unconstrained optimisation methods are likely to lose optimality after manufacturing simplifications are applied. The present paper proposes and evaluates the performance of an optimisation method for wind turbine blades while considering manufacturing constraints. The optimal solution achieved this way is manufacturing-ready. In addition, integrating manufacturing design knowledge into the optimisation is shown to significantly reduce the design space, and therefore the time taken by the optimisation algorithm. While the proposed method herein is described for a standalone aerodynamic optimisation, it can also be used for aerostructural optimisations.
