Effect of Dynamic Stall and Elastic Parameters on the Fundamental Mechanisms of Helicopter Vibrations
Abstract
This research dealt with the modeling and solution of rotary-wing dynamics. In the modeling area, it deals with elastic-blade models, ways to introduce rotor-body coupling, aerodynamic behavior near blade-tips, and the modeling of dynamic stall. In solution strategies, we have concentrated on new and improved Floquet methods, on innovative trim methodologies (such as auto- pilot and periodic shooting), on efficient formulation of equations, and on lifting-line and lifting-surface meshes.
