Mortar projectile warhead mechanically triggered fuze with penetration time adaptation

Abstract

The invention discloses a mortar warhead mechanical trigger fuze with a penetration time self-adaptive function, which includes a body, a pneumatic safety mechanism / trigger firing mechanism, an inertia firing mechanism, an explosion-proof mechanism, a recoil safety mechanism and its anti-recovery mechanism, Delay release of insurance mechanism, setting mechanism, detonator, detonator and bottom screw. The two insurances of the fuze depend on the internal ballistic environment and the external ballistic environment respectively to release the insurance, and the two insurances of the flameproof part are in the insurance state during the loading stage and before the muzzle exit, and the safety is good; and it has the feature of fail-safe , in case the recoil insurance mechanism accidentally releases the insurance, the fuze will automatically transfer to the failsafe state to ensure safety in a credible service processing environment; the booster tube adopts a shaped charge structure with strong detonation ability; Redundant flame-resistant features, high reliability, can ensure the safety of unexploded ammunition and explosives disposal. The fuze has simple structure, easy processing and low cost.

Description

technical field [0001] The invention belongs to mortar shell fuze technology, in particular to a mortar shell warhead mechanical trigger fuze with penetration time self-adaptive function. Background technique [0002] Traditional mortar shells are basically stabilized by tail fins. They do not rotate or spin slightly during the launching phase and the ballistic flight phase. The equipped fuze is used to release the safety when launching. There is only a ballistic environment in the recoil. In order to meet the requirements of fuze redundancy insurance, in addition to the recoil insurance, it is often necessary to add an insurance that can be released manually (such as pulling out the pin or removing the cap). However, the manual release of the insurance must be manually released before the projectile is loaded, that is, the fuze is already in a single insurance state during the loading stage and the in-bore launch stage, which has potential safety hazards. Existing mortar s...

Problems solved by technology

However, the manual release of the insurance must be manually released before the projectile is loaded, that is, the fuze is already in a single insurance state during the loading stage and the in-bore launch stage, which has potential safety hazards

Existing mortar shell fuzes mainly use delayed pyrotechnic devices such as delayed detonators or delay tubes to achieve delayed firing after triggering, and the delayed time is basically fixed and cannot be adjusted; and the fuze has a complex structure, poor manufacturability, and high cost
