摘要: An unsteady Reynolds averaged Navier-Stokes analysis loosely coupled with a comprehensive rotorcraft code for blade trim and aeroelastic effects is presented second-generation Active Twist Rotor. High fidelity results are compared to lifting-line theory based calculations wind tunnel data. Results indicate that the Computational Fluid Dynamics/Computational Structural Dynamics (CFD/CSD) solutions mesh converged in very good agreement flapwise bending moments both low high advance ratio cases presented. The accuracy of predicted rotor torque also across full sweep available comparison
