Structural topology optimization of wind turbine blades fabricated by additive manufacturing

Abstract eng:
This article proposes a method to identify optimal wind turbine blade structures fabricated by additive manufacturing based on topology optimization techniques. The structural model is based on the beam cross-sections through a 2D finite element representation. The optimization problems are formulated through the blade properties and response at the cross-section level. The numerical experiments performed challenge the topology optimization method proposed against several problem formulations, geometries and candidate materials.
