The paper presents the results of supercomputer simulations of turbulent flow around a rotor of a small-scale unmanned aerial vehicle. Rotor aerodynamics and near-field acoustics are modeled using both RANS and scale-resolving hybrid RANS-LES approaches. The underlying numerical method uses an edge-based reconstruction scheme for higher-accuracy discretization on unstructured mixed-element meshes. The far-field acoustics are evaluated using the integral Ffowcs-Williams and Hawkings method. The numerical results are compared with the available experimental data. The simulations were carried out on a hybrid supercomputer using several dozen GPUs. The parallel efficiency of the simulation code and comparison of performance on different types of computing devices are also presented.
