A design study has indicated that advanced composite helicopter airframe structures can provide significant system cost advantages. The most successful concept was found to be all-molded composite modular panels which provide integral skin/stringer and frame subassemblies. Based on present information it is estimated that a prototype composite airframe would cost approximately four percent more than a protoype metal frame. The difference is due primarily to the higher engineering design time, as the increased materials cost is largely offset by reduction of fabrication labor costs. (Author)
