A high-sensitivity impact cap for a fuze

Abstract

The invention discloses a high-sensitivity impact cap for a fuze, which comprises a tube shell, a primer agent and a seat. The tube shell is in the shape of a barrel, the closed end of the barrel is an input end, and the open end is an output end. The flash cap agent and the base are arranged in the tube shell from top to bottom, the flash cap agent is in contact with the input end, the output end is closed to fix the seat, and is sealed by sealing paint. The seat is composed of several cylinders, and the diameter of the cylinder is from top to bottom. Incremental downwards, from the bottom of the pedestal up to the top of the second-order cylinder, there are N through-holes distributed at equal intervals in a ring about the first-order cylinder, and the above-mentioned through-holes do not interfere with the first-order cylinder, and the through-holes Filled with a flammable sealant for sealing, the outer circumferential wall of the lowermost cylinder is in contact with the inner wall of the tube shell. The present invention improves the structural strength of the flash cap by arranging the seat, and when the head of the fuze hits the target, the flash cap agent is supported by the seat to facilitate ignition, and is suitable for warhead triggering the fuze to attack very weak targets such as unmanned aerial vehicles and air balloons high trigger sensitivity requirements.

Description

Technical field [0001] The present invention belongs to the fuze explosion element technology, specifically relates to a kind of induction credit high sensitivity bumper fire cap. Background [0002] Extremely weak targets such as drones and airborne balloons require fuzes to have high trigger sensitivity. The existing high trigger sensitivity fuze mostly adopts the trigger principle of hitting the fire cap (detonator), and when hitting the target, the fuze head cover foil is used to bump the fire cap or touch the detonator. However, these bumper fire caps or bumper detonators are borrowed needle prick fire caps or needle prick detonators, and are not specialized in bumping fire caps or bumping detonators. When hitting the target, its bottom strength is weak, and the corresponding structural seat also leaves a central fire transmission hole, which cannot be supplemented by support and strengthening, so its trigger sensitivity is difficult to improve, and it cannot adapt to the hi...

AI Technical Summary

Problems solved by technology

When it hits the target, its bottom strength is weak, and the corresponding structural base has to leave a central fire transmission hole, which cannot be supplemented by support and reinforcement. Therefore, it is difficult to improve its trigger sensitivity and cannot adapt to the current attack drones. and high trigger sensitivity requirements for extremely weak targets such as air balloons
