介绍了来流引射、不同点火位置及弹丸旋转对底排药柱二次点火影响的风洞模拟实验研究。获得了不同条件下的～t曲线及实际燃面状况.表明来流引射和点火位置是影响二次点火一致性的重要参数.
The wind tunnel simulation experiments on the effects of incoming jet, different ignition positions and projectile rotation on the secondary firing of the bottom row of discharge columns are introduced. Under different conditions, the ~ t curve and the actual combustion surface condition were obtained, indicating that the injection and ignition position of the incoming stream are important parameters that affect the consistency of the secondary ignition.
