    Large, low cost composite wind turbine blades (1979)
    In:  CASI
    Details
    Publication Date: 2016-06-07
    Description: A woven roving E-glass tape, having all of its structural fibers oriented across the tape width was used in the manufacture of the spar for a wind turbine blade. Tests of a 150 ft composite blade show that the transverse filament tape is capable of meeting structural design requirements for wind turbine blades. Composite blades can be designed for interchangeability with steel blades in the MOD-1 wind generator system. The design, analysis, fabrication, and testing of the 150 ft blade are discussed.

    Design, fabrication, test, and evaluation of a prototype 150-foot long composite wind turbine blade (1979)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: The design, fabrication, testing, and evaluation of a prototype 150 foot long composite wind turbine blade is described. The design approach and material selection, compatible with low cost fabrication methods and objectives, are highlighted. The operating characteristics of the blade during rotating and nonrotating conditions are presented. The tensile, compression, and shear properties of the blade are reported. The blade fabrication, tooling, and quality assurance are discussed.

    Wind turbine generator rotor blade concepts with low cost potential (1977)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: Four processed for producing blades are examined. Two use filament winding techniques and two involve filling a mold or form to produce all or part of a blade. The processes are described and a comparison is made of cost, material properties, design and free vibration characteristics. Conclusions are made regarding the feasibility of each process to produce low cost, structurally adequate blades.
