Blade‐Vortex Interaction Airloads Prediction Using Coupled Computational Fluid and Structural Dynamics
Abstract:Correlations using a computational fluid dynamics code and rotorcraft computational structural dynamics code were made in order to calculate the helicopter rotor blade‐vortex interaction airloads for descending forward flight. An iterative loosely coupled trim methodology was used to couple the computational fluid dynamics (OVERFLOW‐2) and computational structural dynamics (CAMRAD
