Design, Evaluation, and Fabrication of Low-Cost Composite Blades for Intermediate-Size Wind Turbines.

Abstract

This report describes the low-cost composite blade program, carried out by Structural Composites Industries, Inc. (SCI) under a contract to NASA-Lewis Research Center, (NASA), funded by the Department Of Energy (DOE), involving design, evaluation and fabrication of a pair of low-cost composite rotor blades (LCCB) for the MOD-OA wind turbine. The objectives of the program were to identify low cost approaches to the design and fabrication of blades for a two-bladed 200 kW wind turbine and to assess the applicability of the techniques to larger and smaller blades. Rotor blades represent a substantial portion of the cost of intermediate to large-size wind turbines, hence low-cost blades are needed to improve the overall cost effectiveness of these systems.
