摘要
为研究外弹道相似理论的应用,分析了外弹道相似性条件的分类特点.针对小弹模拟大弹的具体条件,建立了第4类相似性在非完全相似条件下的外弹道修正方法,分析了弹丸质量和膛线缠度作为非完全相似参数对相似性的影响.试验数据表明,小口径模拟弹修正后与中、大口径基本弹的外弹道相似性良好,研究结果对外弹道相似理论在实际中的应用有借鉴作用.
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.
