Abstract
Wind turbine power is on the rise due to increased energy extraction made possible by longer blades, higher tower heights, and improved electronics. As wind turbine blades get larger, structural compliance is necessary to ensure reliable operation and maintenance. In this paper, structural design and analysis of a redesigned 5MW wind turbine blade was conducted. To ensure that the blade was structurally compliant, the blade tip deflection and engineering strains were not allowed to exceed permissible limits of 5.56 m and .562% respectively. Moreover, the goal was to avoid blade resonance conditions. Structural analysis was conducted and after several iterations, it was observed that mass of the redesigned blade was 7.2% less when compared to the traditional 5MW blade. The maximum flap wise deflection of the blade was 3.31 m, the maximum material strain was .394%, and resonance was avoided ensuring blade structural compliance.
