Abstract

The invention discloses a medium and large-caliber rotary shell warhead mechanical trigger fuse capable of preventing ballistic explosion. The fuse comprises a fuse body (1), a rainproof mechanism (2), a collision trigger mechanism (3), a setting mechanism (4), a safety and safety release mechanism (5), a recoil safety / inertia trigger / centrifugal self-destruction mechanism (6), a booster tube component (7) and a relay tube (8). Wherein the rainproof mechanism (2), the impact triggering mechanism (3), the relay tube (8), the safety and safety release mechanism (5), the recoil safety / inertia triggering / centrifugal self-destruction mechanism (6) and the booster tube component (7) are sequentially positioned in the fuse body (1) from top to bottom and are arranged along the axis of the fuse body (1). And the setting mechanism (4) is positioned between the impact triggering mechanism (3) and the relay pipe (8) and is arranged along the radial direction of the fuze. The device is good in safety, and the ballistic burst problem can be effectively prevented through the design of the safety and safety releasing mechanism (5), especially the centrifugal ball constrained inertia triggering mechanism and the centrifugal sliding block type remote safety releasing mechanism.

Description

technical field [0001] The invention belongs to the technical field of rotary artillery shell fuzes, and in particular relates to a mechanical trigger fuze for middle and large caliber rotary artillery shell warheads capable of preventing ballistic explosion. Background technique [0002] With the implementation of the standard of "Fuze Safety Design Guidelines", fuzes are generally designed with flameproof mechanism, redundant insurance mechanism and delayed release insurance mechanism, and the accidents of handling explosion and chamber explosion have been greatly reduced, but for distribution With the medium and large caliber rotary projectiles that trigger the fuze with warheads, muzzle bombing and ballistic bombing accidents still occur from time to time. Some ballistic explosions occurred at the initial stage of the ballistic trajectory, that is, the moment when the fuze was just released, some occurred at a distance of 500m to 1000m from the muzzle, and some occurred ...
