Abstract

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 of Ф56 mm and Ф60 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.

Key words: shaped charge jet, fuze, shock initiation, sensitivity, reaction characteristic
