STUDY OF BALLISTICS CONSISTENCE BASED ON NUMERICAL SIMULATION OF FLOWFIELD

弹道一致性是制式弹丸在改进过程中经常遇到的工程问题 ,为实现不同头部外形弹丸的弹道一致性 ,采用高精度高分辨率的有限体积TVD格式 ,应用流场数值模拟的方法 ,寻求阻力特性相接近的弹丸外形 ,流场数值模拟和弹道计算结果表明 ,该方法具有一定的可行性 ,对弹道一致性研究具有重要的参考价值 .

Ballistics consistence is an general engi ne er problem when standard projectiles are improved. In order to realize ballistic s consistence of projectiles with different head shape, the high precision and h igh resolution finite volume TVD scheme are applied to numerically simulate air flowfield. The simulation result of flowfield and ballistics shows this method i s feasible and it is useful for study of ballistics consistence.
