Abstract
A loose-coupling technique between a structural dynamics code and a computational fluid dynamics-based ice accretion code is proposed to estimate helicopters’ rotor performance degradation due to icing. The approach consists of a fully-3D flow-droplet impingement-ice accretion analyses, followed by a structural analysis that determines the degraded flight conditions of the helicopter in hover. The proposed technique was applied to a model size rotor for which torque and thrust were measured experimentally. Results were compared to the experiment, as well as to a lower fidelity computational model.
