Zusammenfassung:
The model developed to simulate the motion or helicopter see-saw rotor consists of two elastic blades attached to the deformable shaft with pitch and skew flap hinges. The deformable blades can bend in two perpendicular directions and twist around the straight elastic axis. Nonlinear steady two-dimensional airfoil data are used for aerodynamic loads calculations. The unsteady flow effects are described by dynamic inflow model. The equations or motion are generated from Hamiltons principle in semi-automatic way with most of algebraic manipulations done by computer. The blade deflections are discretized by free vibration modes calculated for rotating blades. The model can be incorporated into computer software for numerical integration and stability analysis. The sample results concern investigation of blade steady motion and dynamic inflow model ing on rotor behaviour.
