• For a M_∞=0.96 transonic flow past a secant-ogive-cylinder-boattail(SOCBT)projectile with and without porous surface at angles of attack, the thin-layer Navier-Stokes approximation with a modified Baldwin-Lomax turbulence model is employed to evaluate the drag and the lift. Computed results show that the porous surface on the boattail of a SOCBT projectile causes effectively the normal shock at the boattail of a solid-surface SOCBT projectile to become a weaker lambda shock, resulting in reduced drag. As the angle of attack is increased, the lift is enhanced for a SOCBT projectile both with and without porous surface.
