This thesis reports on research that has been conducted to obtain a better understanding of the structural coupling parameters that contribute to rotor blade forced response and stability in forward flight. A new analytical method, named eigenvalue and modal decoupling analysis, has been developed to solve the flap-lag equations of motion with periodic coefficients. An extension of the Floquet Transition Matrix Method, the eigenvalue and modal decoupling analysis is used to obtain the forced response of the flap-lag equations. Application of this analysis to study four different rotor configurations has provided new insight into the stability and response problem. The results obtained from an analysis that provides rotor loads and stability simultaneously give the rotor design engineer valuable guidelines to study the tradeoffs necessary during the design phase of new rotor systems.
