| Abstract | The global installed capacity of wind energy has been increasing steadily over the past decade, and the price of electricity derived from it has been continuously declining. While viable siting locations with with high quality wind resources still exist, improved turbine technology and cost reductions can expand the number of locations that are economically viable. This paper investigates the multidisciplinary nature of wind turbine design as it applies to turbine blades. The goal is to reduce the end unit cost of electricity, amortized over the turbine lifetime, for a particular location. A multidisciplinary design feasible (MDF) approach is used for solving the optimization problem. The blade aerostructural analysis couples a quasi-3D aerodynamic analysis | performed using a blade element momentum theory (BEM) method | with a six degree of freedom beam nite element model of the internal spar. Sensitivities for both the aerodynamic and structural analysis are computed using the complex step method. Finally, multipoint optimization of a small 5.0kW xed pitch \urban" wind turbine is performed based on the local wind velocity histograms. |
