弹药殉爆试验与反应等级评估探讨

Sympathetic Detonation Test and Reaction Degree Evaluation of Munitions

目的获取弹药在殉爆情况下发生反应的特征行为,为不敏感弹药的评定以及弹药安全性的评估提供技术支撑。方法参照北约STANAG 4396标准,开展某型弹药殉爆试验。采用超压测量、见证板变形破坏情况观测、破片速度测量等传统测试方法,结合先进的激光干涉测速技术(Photonic Doppler Velocimetry—PDV)测量被发弹药及主发弹药反应后壳体膨胀速度。结果被发弹药侧见证板比主发弹药侧见证板产生了更严重的变形。11 m和14 m处超压测量结果分别达到306 kPa和177 kPa,与两枚弹药爆轰后产生的超压相当。被发弹药和主发弹药的壳体膨胀速度相当,达到约3500 m/s。结论在试验条件下,被发弹药发生了爆轰反应,该弹药不属于不敏感弹药。在殉爆试验中,主发弹药和被发弹药的壳体膨胀速度可作为判断被发弹药反应等级的关键参量。

Objective To obtain the reaction degree of munitions under sympathetic detonation,to provide technical support to the evaluation of munitions safety and sensitivity.Methods The sympathetic detonation test of a certain type of munition was carried out based on the STANAG 4396 of NATO.The overpressure,the distortion and damage of witness,the velocity of fractions were measured;additionally the expanding velocities of munitions case were obtained based on the Photonic Doppler Velocimetry-PDV).Results The flank witness face to the acceptor distorted more seriously than to the donor.The overpressure at 11 m and 14 m was 306 kPa and 177 kPa,which was almost the same as the effect of two munitions detonated.The case expanding velocities of donor and acceptor were also equivalent,which was about 3500 m/s.Conclusion In the given experiment conditions,the acceptor detonated.So the munition does not belong to insensitive munitions.In sympathetic detonation test,the expanding velocities of munitions case(both donor and acceptor)may be the key parameters to judge the reaction degree of munitions.
