Abstract
This paper compares the ONERA deforming grid and the DLR chimera Euler method for isolated rotors in high speed forward flight. The following investigations were carried out: Using the DLR chimera method the effect of the far field distance, of introducing an artificial hub boundary and of changing the position of the blade root were investigated. The sensitivity of the method to the dihedral of the blade was shown by running one computation without dihedral. The ONERA and DLR methods are compared in terms of pressure coefficients, z-force coefficients and vorticity plots. The overall agreement of the methods with each other and with the experimental data for the ONERA PF1 rotor in high speed forward flight is very good.
