Abstract:

Large amplitude nonlinear oscillations of rotor blades due to self-excitation flutter or external excitation mechanical or aerodynamic frequently occur and are often design critical for rotorcraft. The present work is a combined theoretical-experimental study to develop improved understanding and mathematical models for enhanced design and performance. AN
