The accurate calculation of Magnus force and moment is essential to the design, trajectory calculations and stability analysis of rotation missiles. The unsteady Reynolds averaged Navier-Stokes (RANS) method is taken to simulate the flow over the high-speed spinning projectile SOCBT. The longitudinal aerodynamic characteristics over the entire range of angles of attack are consistent with the experimental data, while the lateral aerodynamic characteristics, including Magnus force and moment, in a small angle of attack range are in good agreement with the experimental data, but the deviation is evident in the range of high angles of attack. The adoption of the delay detached eddy simulation (DDES) method has a significant improvement in the range of high angles of attack, and comparative studies have shown that the separation point has a significant influence on Magnus effect. The results show that the DDES method has great potential for improving the simulation accuracy of Magnus effect of the spinning missiles.
