This paper demonstrates the capabilities of the DLR's CFD code (FLOWer) to predict air flow past helicopters via the solution of the compressible Navier-Stokes equations in three dimensions. Both the stationary actuator disc and a time accurate moving Chimera method were applied to simulate low Mach numbers, forward flight flow cases. The flight conditions correspond to wind tunnel measurements of a scale model of an Eurocopter BO-105 helicopter for a range of Reynolds and Mach numbers of 11 to 12 Million and 0.125 to 0.135 respectively. The numerical approach is based on finite volume discretization and a two-equation eddy viscosity k-omega model. Comparison of the results with experimental measurements revealed that both the model support and spoiler play a dominant role in determining the overall flow pattern around the aircraft.
