Abstract:

This report describes the results of a research and development program to design, analyze, and fabricate a 16-foot-long section, including the root end attachment, of an HLH size rotor blade. The design of the blade section was based upon the tubular-rein-forced-composite wet-filament-wound concept. The blade design and the fabrication techniques developed are new and can be appli- cable to low-cost automated composite helicopter rotor blade fabrication. Fibrous materials used in the blade include S-Glass, Kevlar 49, and Thornel 300 graphite, all of which were held by an epoxy resin matrix. All materials were utilized effectively in order to obtain maximum utilization of properties at minimum cost. Design and fabrication techniques discussed are novel and resulted in improved methodology.
