Design Study of Expendable Main Rotor Blades

Abstract

A design study is performed to determine the feasibility and cost advantages of expendable main rotor blades designed for the UH-1H helicopter. Technical feasibility, manufacturing cost, reliability, maintainability, and life-cycle costs were determined. Three concepts were projected to have life- cycle costs lower than those of the current blade. A blade of simplified all- aluminum construction is shown to have the lowest initial procurement cost, while one of stainless steel sheet and fiberglass has the lowest life-cycle cost.
