Keywords: high-resolution scheme, helicopter rotor, multi-grid method

In this paper, some high-resolution schemes including Roe and AUSM are developed and investigated for rotor flow simulation. Moving chimera-grid methodology is implemented to account the relative motion among the blades. Full implicit dual-time stepping method and multi-grid scheme are utilized to improve the accuracy and efficiency.
