Abstract

A procedure is described for the minimum weight design of helicopter rotor blades with constraints on multiple coupled flag-lag natural frequencies, autorotational inertia, and centrifugal stress. Optimum designs of blades with both rectangular and tapered planforms are obtained in typically 8-10 cycle. The results of the study indicate that a significant reduction in blade weight is possible, even with constraints on multiple natural frequencies, for both the rectangular and the tapered blades.
