DEVELOPMENTS IN LARGE BLADESFOR LOWER COST WIND TURBINES

摘要

WindPACT scaling and concept studies have looked at identifying issues and constraintsrnassociated with growing turbines from 1-10 MW. As part of the WindPACT project, thernBlade System Design Studies developed innovations in manufacturing, materials, and designrnthat would alleviate issues and provide breakthroughs in constraints identified for large bladernproduction. This paper describes the recent and predicted trends in blade-size growth andrnnew COE goals developed by DOE’s wind program. It also provides sample results fromrnWindPACT studies and associated blade research activities that facilitate larger bladerndevelopment in ways that reduce COE.
