摘要

Vibratory hub loads predicted by a comprehensive aeroelastic analysis are compared with wind tunnel test data. The analysis is based on a finite element method in space and time. Rotor loads are calculated using a force summation method. The test data include several model rotor configurations with different mass and stiffness distributions along the blade. The influences of unsteady aerodynamics and nonuniform inflow o variation of rotor loads prediction are in vestigated.
