Naval vessel cabin spraying and explosion suppression system

Abstract

The invention relates to a naval vessel cabin spraying and explosion suppression system. The naval vessel cabin spraying and explosion suppression system comprises a pre-warning sub system, a controlsub system and a spraying sub system; the pre-warning sub system is used for detecting the movement locus of an enemy attack weapon and sending a pre-warning signal; the control sub system is used forreceiving the pre-warning signal of the pre-warning sub system, judging the hitting part of the enemy attack weapon and sending a spraying starting instruction to the spraying sub system according toa judging result; and the spraying sub system is used for receiving the spraying starting instruction of the control sub system and starting the spraying at a corresponding part before an anti-ship weapon warhead explodes. Due to being used together the existing protection structure, the naval vessel cabin spraying and explosion suppression system can rapidly absorb explosion energy by using theliquid drop compressing, crushing, dispersing and atomizing process and the water mist heat-absorbing and gasifying process when explosion in a vessel generation cabin generates shock wave and quasi-static gas pressure load; and therefore, the strengths of the explosion shock wave and the quasi-static gas pressure are weakened and the damage degree of the cabin structure is also reduced; and correspondingly, the design weight of the structure can be reduced under the same protection grade requirement.

Description

technical field [0001] The invention relates to the technical field of explosion suppression for ship cabins, in particular to a spray explosion suppression system for ship cabins. Background technique [0002] With the rapid development of modern anti-ship weapons, various high-performance semi-armor-piercing anti-ship weapons have become the main threat to the side of surface ships above the waterline. According to Delmar’s empirical formula, taking the famous American Harpoon (AGM-84A) missile as an example, when the warhead of the missile hits the side at a speed of 340m / s, a steel armor with a thickness of 79.3mm is required to resist its kinetic energy penetration. Modern surface ships generally adopt thin-walled structures, so anti-ship weapons penetrate the side shell and explode in the ship cabin, which is the most important form of shock load for ship structures. [0003] Under the explosion in the cabin, the shock wave will reflect in multiple directions, and the...

Problems solved by technology

But once the missile warhead penetrates the protective structure, there is no other device that can weaken the shock wave and quasi-static air pressure of the anti-ship weapon intruding into the ship cabin. If a device can be installed inside the protective structure that can weaken the shock wave and quasi-static air pressure The device, under the same protection level requirements, can reduce the structural weight of the protective armor to a certain extent
