Abstract
A weak coupling procedure for coupling the rotor simulation code S4 and the Euler/Navier-Stokes solver FLOWer is presented. The method allows the produce trimmed CFD solutions for rotors in high speed forward flight accounting for elastic blade deformations and viscous effects. The weak coupling procedure is applied to a high-speed forward flight test case of the 7A rotor. Only isolated blade computations are carried out. The predicted pitching moment computed with the assumption of inviscid flow shows large differences compared to the experimental data while the Navier-Stokes computation agrees much better with the measured data. The weak coupling considerably improved the solution.
