Book excerpt: This report describes the development of a low cost wind turbine blade design based on a stainless steel/fiberglass foam design concept and to evaluate its principle characteristics, its low cost features, and its advantages and disadvantages. A blade structure was designed and construction methods and materials were selected. Complete blade tooling concepts, various technical and economic analysis, and evaluations of the blade design were performed. A study was made to determine the applicability of the blade design concept to various blade lengths in the range of 15 ft. to 200 ft. A test specimen of the spar assembly, including the root end attachment, was fabricated. This 20 ft. long full-scale section will be fatigue tested by NASA. It was concluded that the stainless steel/fiberglass-foam blade concept is a viable design for application to large wind turbine systems. A blade design was completed which meets the requirements for operation on the MOD-OA wind turbine. The design concept is applicable to various length blades. Blades less than 60 feet would use a stainless steel spar and blades of larger size would have a fusion welded carbon steel spar. The design permits a choice of a wide selectivity of air-foil shapes and, because of its modular construction, the design provides producibility and quality in high volume production.

Book excerpt: As part of the U.S. Department of Energy's Wind Partnerships for Advanced Component Technologies (WindPACT) program, Global Energy Concepts LLC (GEC) is performing a study concerning innovations in materials, processes and structural configurations for application to wind turbine blades in the multi-megawatt range. The project team for this work includes experts in all areas of wind turbine blade design, analysis, manufacture, and testing. Constraints to cost-effective scaling-up of the current commercial blade designs and manufacturing methods are identified, including self-gravity loads, transportation, and environmental considerations. A trade-off study is performed to evaluate the incremental changes in blade cost, weight, and stiffness for a wide range of composite materials, fabric types, and manufacturing processes. Fiberglass/carbon fiber hybrid blades are identified as having a promising combination of cost, weight, stiffness and fatigue resistance. Vacuum-assisted resin transfer molding, resin film infision, and pre-impregnated materials are identified as having benefits in reduced volatile emissions, higher fiber content, and improved laminate quality relative to the baseline wet lay-up process. Alternative structural designs are identified, including jointed configurations to facilitate transportation. Based on the results to date, recommendations are made for further evaluation and testing under this study to verify the predicted material and structural performance.
