Abstract

The invention discloses a spiral gunpowder accelerator. The spiral gunpowder accelerator has the advantages that spiral gunpowder charging is carried out in a barrel inner shell, and the gunpowder combustion surface follow-up principle is used for supplementing the bullet bottom pressure drop in time, balancing the bullet bottom pressure and improving the bullet outlet speed. The spiral gunpowder accelerator comprises a launching mechanism, a shearing sheet, a projectile, a sectional type combined barrel, an outlet cap, a barrel mounting base, a sealing film and a vacuum pump. The launching mechanism is used for charging exciting powder and propellant powder and is of a step structure on the whole. The sectional type combined barrel comprises a barrel outer shell and the barrel inner shell, and the barrel outer shell is embedded into the launching mechanism and the outlet cap in a threaded connection mode. A spiral groove is formed in the barrel inner shell and is used for charging gunpowder. The outlet cap is provided with a threaded through hole connected with the vacuum pump. The barrel mounting base comprises a barrel mounting platform, a support, a fixing baffle, a fixing flange and a bolt. The spiral gunpowder accelerator has the advantages that the outlet speeds of different projectiles can be adjusted, all the assemblies are assembled through bolts and nuts, and the device is convenient to transport, mount and dismount.

Description

technical field [0001] The invention belongs to the technical field of launching devices, and in particular relates to a spiral propellant accelerator. Background technique [0002] Due to the indisputable superiority of high muzzle velocity projectile launching devices in modern technology, researchers from all over the world have been constantly exploring and studying how to increase the launch velocity of projectiles. At present, there are three ways of launching projectiles or fragments: light gas cannon, electromagnetic gun and gunpowder. Chinese patent CN108362169A introduces a device that uses a light gas cannon to launch. This device uses the pressure difference between the inside of the cylinder and the atmosphere to push the ram to hit the piston rod, so that the high-pressure gas enters the gun barrel at the maximum flow rate instantly to push the projectile or bird bomb. Although the projectile can be accelerated to the preset speed, it can only accelerate the ...
