Caseless cartridge

Abstract

The invention relates to a caseless cartridge. The caseless cartridge is composed of a propellant powder column, a primer, a warhead, starting powder, a dampproof wrapping body and an isolating heat dissipation wrapping body, wherein the warhead is composed of a head cone, a cartridge belt, a tail protrusion or a missile wing and a tail post and is fixed into a center hole of the molded solid propellant powder column. The tail post of the warhead abuts against the primer. The warhead has the functions of a traditional bullet primer platform and an anvil. The starting powder with the burning rate higher than that of the propellant powder column is arranged in front of the primer and behind the tail protrusion or the missile wing to make percussion of the cartridge be stable and reliable. The dampproof wrapping body is made of a water-repellent organic thin film material and wraps a cartridge body completely to achieve the effective dampproof effect, and accordingly the misfire rate is reduced. The isolating heat dissipation wrapping body is made of metal foil with good heat conductivity so that temperature rising of the cartridge body can be effectively delayed, the high-temperature resistant performance of the cartridge body is improved, and adhesion between the dampproof wrapping body and a cartridge chamber is effectively isolated. The caseless cartridge is compact in structure and low in weight; the firing distance and penetrating power are increased, and the damage effect is improved; and the underwater using effect of the cartridge with a spiral wing is remarkable.

Description

technical field [0001] The present invention relates to a caseless ammunition, in particular to a caseless ammunition for muzzle-loading guns. Background technique [0002] Caseless bullets are bullets without shells. Strictly speaking, they are bullets with a small amount of residue after firing. At present, the more reliable method of realization is to first bond the propellant powder with a combustible binder, and then mold it into a solid propellant column. Then the warhead and the primer are respectively embedded in the two ends of the powder column, and the powder column replaces the cartridge case as the carrier of the bullet. Because this kind of bullet omits the shell of traditional bullets, the weight of a single shot is greatly reduced. The weight of 100 rounds of caseless bullets is only equivalent to the weight of 20 conventional bullets, so soldiers can carry more bullets with them during wartime , effectively improving the continuous combat capability of indi...

Problems solved by technology

However, the current caseless bullets have two fatal flaws. The first is the problem of spontaneous combustion. When the gun is fired continuously, the temperature of the chamber will rise sharply and cannot dissipate heat in time. , as a result, when the chamber temperature is higher than the self-ignition temperature of the propellant, the bullet will spontaneously ignite and be dangerous. The main reason for this is the gun, but the improvement of the bullet is also very important

The second is the problem of moisture resistance. Since the bullet has no case, the powder column will be exposed to the natural environment. Long-term storage will inevitably be affected by moisture, which will greatly increase the misfire rate of the bullet.

Since the above-mentioned problems have not been well resolved, no country has installed and used caseless ammunition in the world, and the research on the system has gradually become cold
