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

no. 1 approach

[0025] like figure 1 As shown, the caseless bullet of this embodiment is composed of a propellant column 101 , a warhead 102 , a primer 103 , a fast-burning charge 104 , a moisture-proof plastic film 105 , and an isolation and heat dissipation aluminum foil 106 . The propellant powder column 101 is bonded with the propellant powder by a combustible adhesive, and then molded into a solid propellant powder column. Its shape is a right cylinder or other shapes according to the needs of the adapted gun. The rear section through the hole and near the primer has a step to allow the entire bullet to be buried in the hole. like figure 2 As shown, the warhead 102 is composed of a nose cone 1021, an elastic band 1022, a tail protrusion 1023, a rear elastic band 1024, a tail post 1025 and other parts. The function of the nose cone 1021 is well known and will not be discussed here. The bullet band 1022 is the main contact surface between the bullet and the gun barrel. Its first functio...

[0027] like image 3 As shown, the bullet of the caseless bullet of the present embodiment is assembled, and is made up of bullet jacket 201, lead filling 202, and bullet core 203. Tail protrusion, rear bullet belt and tail post are on bullet core 203. When the warhead has a spiral wing, the spiral wing and the tail post are on the bullet core 203.

no. 3 approach

[0029] This embodiment is an embodiment of a warhead with a helical wing, see Figure 4 , consists of a propellant charge column 301, a warhead 302, a primer 303, a fast-burning charge 304, a moisture-proof plastic film 305, an isolated heat-dissipating copper foil 306, and an interwing charge 307. The propellant column 301 also uses a combustible adhesive to first bond the propellant powder, and then molds it into a solid propellant column. There is a through hole in the center of the column to accommodate the entire warhead. There is a boss on the rear side of the position, which acts on the rear side of the belt to prevent the warhead from moving in the direction of the primer. like Figure 5As shown, the warhead 302 is composed of a nose cone 3021, an elastic belt 3022, a spiral wing 3023, and a tail post 3024. The functions of the nose cone 3021 and the elastic belt 3022 are the same as those in the first embodiment. The helical wing 3023 is a sheet-shaped body that ext...

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...
