Expansion wave firearm

Abstract

The invention relates to a dilatational wave firearm. The technical scheme mainly includes that: a reaction gas discharge structure is composed of a flame vent hole which is on the firearm tube wall and connected with a bore, and a thrust jet connected with the flame vent hole, in the process from the begin of the internal trajectory to the end, the reaction gas, which goes from the bore and flame vent hole to the thrust jet connected with the flame vent hole, jets to form the counterforce which counteracts the recoil. The invention has the advantages that: 1. The invention not only can use whole combustible cartridge cases ammunition, but also can use the most common metallic cartridge case gun propellant fixed-loading charge at present. 2. The invention can use the single ignition, semi-automatic, automatic and other automatic modes, the problems of unlock, case-drawing and ejecting, prime, block and due out and so on can be solved the same as those in the common firearm, the invention can work in cartridge clip, ammunition drum, ammunition belt and other common prime again running fire types. 3. The invention can be applied for traditional self-propelled gun and tank whose gun breech is in the enclosed turret.

Description

1. Technical field: [0001] The invention relates to an expansion wave gun, in particular to an expansion wave gun with low recoil force, light weight and high efficiency without reducing the initial velocity of projectiles. 2. Background technology: [0002] When a traditional gun is fired, the ignited propellant produces a large amount of high-temperature, high-pressure propellant gas, but only 20% to 30% of the chemical energy is converted into the kinetic energy of the projectile, making it fly out of the gun muzzle at high speed, while More than 70% to 80% of the energy is released in the form of the muzzle flame of the gun, which produces a huge recoil. In order to combat the huge recoil force, traditional guns use a large number of brakes, buffers, and reset devices, resulting in a significant increase in the weight of the weapon system, which seriously affects the use, carrying and transportation of the weapon. Ordinary recoilless guns and rocket launchers spray gun ...

AI Technical Summary

Problems solved by technology

[0007] However, the current US expansion wave artillery project has a structural defect, because it directly opens the breech breech breech of the gun breech to discharge the high-temperature and high-pressure propelling gas through the recoil movement of the breech at the right time in the inner trajectory. This structure determines that it has three One defect: firstly, the expansion wave artillery in the United States can only use fully combustible cartridges, and cannot use the existing conventional metal cartridge fixed ammunition. Because of this structure, if ordinary metal cartridge ammunition is used, the recoil movement of the gun tail will directly open the gun. When the high-temperature and high-pressure propelling gas is discharged from the breech breech at the tail, the metal shell casing will be partially crushed by the high-temperature and high-pressure propelling gas and ejected backward at high speed together with the gun tail flame, which has a certain lethality to the rear. Part of the cartridge is deformed so that the weapon jams and cannot be fired continuously

Secondly, the recoil movement of the gun breech during the inner ballistic period and the opening of the structure to discharge high-temperature and high-pressure propelling gas backwards make it difficult to solve the problem of continuous reloading of the weapon, and cannot be reloaded using conventional magazines, ammunition chains, etc. Continuous firing, the current expansion wave artillery in the United States can only use the design of the rotary gun to initially solve the related problems of reloading, but the structural weight is greatly increased

Finally, the recoil motion of the gun breech directly opens the breech block of the breech to discharge the high-temperature and high-pressure propelling gas structure, which determines that it cannot be applied to traditional self-propelled artillery and tanks whose gun tail is located in a closed turret, because the closed turret cannot adapt to the exhaust of the gun tail flame. , so the current expansion wave artillery in the United States can only be imagined to be used in top-mounted self-propelled artillery and external weapon systems
