Numerical simulation on aerodynamic characteristics of rolling rocket with wraparound fins

The rolling characteristics of the rocket with wraparound fins were numerically simulated by means of the slide mesh technology of CFD. The Magnus force simulation results were analyzed and compared with wind tunnel test data. The error analysis results verify the accuracy of the slide mesh technology for simulating the rolling characteristics of rocket with wraparound fins. The comparison between simulation results and wind tunnel test data shows that rolling characteristics has less effect on lift coefficient and drag coefficient of the slender rocket with wraparound fins, so lift coefficient and drag coefficient of the non-rolling rocket can be used as simulated value under the certain rolling velocity condition. Finally aerodynamic parameters of the rocket under rolling movement can be obtained.
