The mass and stiffness distributions for helicopter rotor blades are to be tailored in such a way to give a predetermined placement of blade natural frequencies. This optimization problem is addressed in a methodical, step-by-step process in which each aspect of the optimization is studied in detail. Careful consideration is also given to the mathematical formulation of the problem and to the introduction of appropriate constraints.
