| 摘 要： | 为掌握聚能射流冲击引信的物理过程及引信的射流冲击感度,获取影响冲击起爆的因素,实现低射流起爆感度引信的目的,开展不同口径聚能装药,不同装药引信,不同装配状态下的引信射流冲击试验。采用高速照相机、超压传感器及见证板分别记录冲击起爆过程和引信响应程度。试验结果表明:2倍炸高条件下Ф50 mm和Ф60 mm聚能装药射流冲击会使引信发生爆轰响应;钝感装药和传统装药引信在射流冲击作用下均会发生爆轰响应;裸装引信和带弹体引信在聚能金属射流冲击作用下分别发生爆轰响应和部分爆轰响应。

| Abstract: | In order to master physical process of fuze being impacted by shaped charge jet and its jet impact sensitivity,and to obtain factors affecting shock initiation and ultimately achieve low jet initiation sensitivity fuze,impact experiments were carried out for shaped charges of different diameter,different fuzes and different configurations.Then,process of shock initiation and jet response degree were recorded by a high-speed camera,an overpressure sensor and a witness board.The results show that detonation occurs within a fuze when shaped charges at diameter ofФ56 mm andФ60 mm is used in condition of two times burst height.There is detonation risk in both insensitive and conventional fuzes under impact of shaped charge jet.The response extent of bare fuze and fuze with projectile to jet are detonation and partial detonation respectively. |
