Accurate prediction of rotorcraft flow fields for brownout, computed using an incompressible flow solver SAGE with Vorticity Confinement, is demonstrated in our fluid dynamics video. The main problem addressed here is the simulation of effects of particulate pick-up during rotorcraft landing maneuvers, which can lead to very dangerous conditions, such as loss of visibility. This technical problem requires rapid, accurate prediction of rotorcraft flow fields in ground effect, including particulate pickup and transport, and its effects on pilot visibility (such as brownout from sand). Solution of this problem will give engineers a simulation tool with which they can develop landing descent trajectories and pilot training techniques that minimize these problems.
