Application Research on Similar Theory of Exterior Ballistics

To study the application of similar theory of exterior ballistics,the classifying speciality on similar conditions of exterior ballistics was analyzed.Based on the similarity conditions between small-caliber projectiles and medium-caliber projectiles,the correcting method of unsatisfied similar conditions was set up for the fourth similarity of exterior ballistics.The effect of unsatisfied similar parameters such as projectile mass and rifling angle was analyzed.The experimental data show that,after correcting,the ballistic parameters of small-caliber simulative projectiles and medium-caliber former projectiles are similar.All of these are useful for application of similar theory of exterior ballistics in practice.
