	abstract = "Optimization techniques were applied to various rotor dynamics problems to project potential design benefits and evaluate alternative optimization algorithms and problem formulations. A constrained optimization program was linked to a coupled-mode eigenvalue analysis to achieve a closed-loop computer program for optimizing blade dynamic characteristics. Analytical studies were performed on a series of problems related to maximizing bearingless rotor inplane structural damping, placing blade natural frequencies, minimizing hub modal shears, and minimizing rotor modal vibration indices. These examples were representative of a hierarchy of optimization problems from relatively simple to complex, involving nonlinearities, multiple design criteria, multicomponent objective functions, and large numbers of design variables.",
