爆炸螺栓作用同步性对弹丸着靶影响规律

针对火箭橇试验中弹丸终点弹道参数的准确性直接影响到弹丸终点效应评估的真实性，提出爆炸螺栓作用的时序及同步性对弹丸运动参量及着靶姿态的影响规律；利用CFD-FASTRAN气动力分析软件进行了数值模拟研究，分析了弹丸着靶运动参量及着靶攻角的变化关系，从中得出了爆炸螺栓作用的时序及同步性对弹丸运动参量及着靶姿态的影响规律；结果表明：爆炸螺栓作用时序及同步性对弹丸的运动参量及着靶姿态的影响较小。

Influence of Explosive Bolts’Synchronization on Projectile Impact Attitude

The accuracy of the rocket sled test parameters for the projectile ballistic projectile end effects directly affects the authenticity of the effectiveness assessment,and we proposed the influence law of explo-sive bolts timing and synchronization on parameters of projectile motion and the law of the attitude of the target;Numerial simulation study of the analysis software was proposed by using pneumatic dynamic code CFD-FASTRAN.The variation relations between projectile’s movement parameters and target attack angle were analyzed.The results show that the influence of explosive blots’action sequence and synchronization on projectile’s movement parameters and impact attitude is negligible.
