The integral aerodynamic forces, flow characteristic, grid effect of aircraft configuration are calculated in low mach number region at high angle of attack. The comparison and analysis of RANS and DES calculation results of different grid scales can provide an effective and experimental reference to simulate aircraft massive separated flow and stability characteristic.
