| 1 | Flow computations past a triangular boattailed projectile显示文摘This paper presents a computational study of the air flow past a triangular boattailed projectile.The study shows that there is a single normal shock wave impinges the projectile at transonic speeds.At supersonic speeds,the formed shock waves are smeared compared to a conical boattailed projectile.Also,there is a reduction of the wake region behind the triangular base and the rear stagnation point is nearer to the projectile base resulting in base drag reduction.Moreover,there is an improvement of the stability of the triangular boattailed projectile since a lower overturning moment is incurred. | E.Elawwad A.Ibrahim A.Elshabkaa A.Riad | 2020 | Defence Technology(防务技术)2020，16，3： | 1 |
