Abstract

The invention discloses an insensitive bullet mechanical trigger fuse for a shell. The insensitive bullet mechanical trigger fuse for the shell comprises a hood, a rainproof mechanism, a fuse body, a collision trigger mechanism, a setting mechanism, an inertia delay trigger mechanism, a safety and safety release mechanism, a detonating tube component and a booster tube component, wherein the hood, the rainproof mechanism, the collision trigger mechanism, the setting mechanism, the inertia delay trigger mechanism, the safety and safety release mechanism, the detonating tube component and the booster tube component are sequentially arranged along the axis of the fuse body from top to bottom; a through hole is formed in the middle of the fuse body in the radial direction and communicates with a ring groove in the fuse body; a fusible metal sheet is arranged at a sealing step hole at the outer end of the radial through hole; and the ring groove communicates with the detonating tube component and the booster tube component through the inertia delay trigger mechanism and the safety and safety release mechanism. The insensitive bullet mechanical trigger fuse for the shell is good in safety, not only meets service processing safety, launching safety and muzzle safety, but also can meet related cook-off test, gun test, fragment test and sympathetic detonation test requirements for insensitive fuses.

Description

technical field [0001] The invention belongs to the technical field of shell fuzes, in particular to an insensitive warhead mechanical trigger detonation fuze. Background technique [0002] Existing cannonball fuzes, such as the M739A1 fuze in the United States, cause a slow increase in the ambient temperature when a fire occurs in the adjacent warehouse or a rapid increase in the ambient temperature when encountering a fire. Explosion occurs due to thermal decomposition in the room. When subjected to bullet shooting, fragmentation strikes and shaped energy jet attacks, the detonating charge and booster charge may also be strongly impacted and explode. In addition, the accidental explosion of the ammunition when stored in the warehouse will also cause damage to adjacent ammunition. The sacrificial explosion, the security is poor. Therefore, the fuze is required to meet the relevant requirements for insensitive fuzes in addition to meeting the traditional safety requirements...
