Abstract:

This report presents the work done in evaluating the design concepts applicable to helicopter main rotor blades assessing cost, repair-ability, maintainability, and survivability and determining overall blade-related costs for the helicopter life cycle. The concept showing the most potential for improved operating costs, without technical compromise, is chosen for further development and has extruded aluminum spar and trailing-edge spline, grass-fiber-reinforced-plastic skins, nylon paper honeycomb core, and built-up laminated metal root.
