摘要：
The aerodynamic performance of a spinning secant-ogive-cylinder-boattail (SOCBT) projectile in the transonic regime is numerically investigated. In the present study, a porous surface is applied to improve the projectile performance. The computed results show that the porous surface on the boattail not only reduce the total drag by 17.35% but also alleviate the magnus force by 98.43%. For the case that the porous surface is on both the boattail and the base of a SOCBT projectile, the total drag and the magnus force can be further reduced by 23.49% and 99.94%, respectively.
