Enthalpy-increasing continuous combustion propelling device

Abstract

The invention discloses an enthalpy-increasing continuous combustion propelling device which comprises a charging structure regularly arranged on the inner wall of a barrel, and the charging form can be a groove, a powder chamber and the like. After a projectile is propelled by a primer, shock waves are formed forward, and a charging structure is ignited under the compression of high-temperature and high-pressure fuel gas, solid particles and the shock waves at the bottom of the projectile; the pressure gradient formed in the rear space of the projectile due to high-speed movement of the projectile is reduced, the influence of sparse waves is weakened, and high and approximately constant pressure is formed at the bottom of the projectile; and the enthalpy value of a system behind the projectile is increased, and the total temperature is increased, so that the projectile reaches a higher speed. According to the structure charging, gaps between riflings in the gun barrel , or grooves, pits and the like can be adopted for charging, and the arrangement form, such as spiral distribution and linear distribution, is determined according to the requirements. According to the propelling device, not only is the outlet speed of the projectile increased, but also the chamber pressure of a main powder chamber is further reduced.

Description

technical field [0001] The invention belongs to the technical field of launching, and in particular relates to a self-increasing enthalpy continuous dynamic combustion propulsion device. 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 exploring and studying how to increase the launch velocity of projectiles or fragments. From the early artillery and light gas guns to the later electromagnetic guns and electrothermal chemical guns, a series of new acceleration methods have been developed. Although the above methods have their own advantages at present, due to the influence of the current basic conditions, funds and applications, it is still difficult to apply their technology to actual combat and engineering damage end-point effect impact experiments in a short period of time. [0003] Current launching devices are mainly based on artille...

Problems solved by technology

However, the acceleration projectile of the electromagnetic gun needs to be accelerated by multi-stage coils. The operation of the acceleration process is very complicated. It can only launch ultra-high-speed fragments of the gram mass level, and when the capacitor charges and discharges the coil, the current is very large, which will cause overheating and reduce the electromagnetic force. gun life
