Rotating bomb fuse explosion propagation isolation mechanism capable of realizing explosive treatment and insensitive characteristics

Abstract

The invention discloses a rotating bomb fuse explosion propagation isolation mechanism capable of realizing explosive treatment and insensitive characteristics. The rotating bomb fuse explosion propagation isolation mechanism comprises an isolation medium, a cover cap and an isolation seat. The cover cap and the isolation seat form a closed cavity for accommodating the isolation medium, and the isolation medium is not filled but a part of the cavity is reserved. The rotating bomb fuse explosion propagation isolation mechanism is located between a detonating tube and a booster tube. If the fuse detonating tube does not work normally, after a projectile falls to the ground and stops moving, due to the fact that no centrifugal force exists, the isolation medium closes an explosion energy-gathered jet explosion channel formed between the detonating tube and the booster tube due to rotation under the action of gravity; therefore, even if the detonating tube explodes due to accidental ignition of detonating sequence sensitive explosion elements such as a detonator, the booster tube cannot be detonated; and if the detonating tube is accidentally ignited due to baking of the fuse and impact of bullets, jet flow or fragments during service treatment, the isolation medium can prevent the detonating tube from detonating and does not detonate the detonating tube; The rotating bomb fuse explosion propagation isolation mechanism capable of realizing the explosive treatment and insensitive characteristics can be matched with various rotating bomb instant firing, near-explosion or air-explosion fuses, and the original structure is not changed and is only increased by about 5-10mm.

Description

technical field [0001] The invention belongs to fuze safety technology, and in particular relates to a rotary bomb fuze explosion transmission and isolation mechanism that realizes explosive disposal and insensitivity. Background technique [0002] With the development of modern warfare, higher requirements are put forward for fuze performance. According to the GJB373B-2019 "Fuze Safety Design Guidelines" standard, the fuze should have explosive disposal characteristics to ensure the safety requirements of ammunition explosive disposal. Not only that, but in order to ensure adequate safety against accidental stimuli such as shock, impact and fire, modern fuzes should also have insensitivity properties. The improvement of the insensitivity of traditional fuzes is generally achieved by selecting extremely insensitive explosives such as triaminotrinitrobenzene. Compared with the booster, when the detonating charge is an extremely insensitive explosive with lower sensitivity, ...

AI Technical Summary

Problems solved by technology

Compared with the booster, when the detonating charge is an extremely insensitive explosive with lower sensitivity, the power of the detonator of the detonating tube is limited by the flameproof safety of the fuze mainly due to the structure of the fuze, so it is difficult to increase the power of the detonator and cannot be reliable. Nonel for detonating extremely insensitive high explosive

Limited by the overall size of the fuze, the fuze should not use a more complex structure to achieve the above functions
