This paper discusses a design tool used to aid in the conceptual development of the Rotor/Wing high-speed rotorcraft concept. By using this tool, a minimum weight blade design can be found. Optimization of the blade is carried out varying the thickness of structural components in the blade for three different configurations. The blades must perform under two distinct loading conditions, subject to constraints on strength, buckling, displacement, and geometry. A composite box beam models the blade for analysis. Results from a sample case are included to show the capability of the design tool. It was shown that the tool works well, and it demonstrates practical applications of anisotropic beam modeling and composite strength analyses.
