Super-High Initial Velocity Mechanism of Bullet Propulsion with Adaptive Pressure-Maintaining Chamber

To deal with the problem that the initial velocity of the bullet is difficult to increase, the research on the super-high initial velocity propulsion in the barrel weapon with an adaptive pressure-maintaining chamber are conducted. Considering the law of gun-powder burning and the flow characteristics of gun-powder gas in multi-chamber, the scheme of super-high initial velocity propulsion with an adaptive pressure-maintaining chamber is designed, the ballistic model of the barrel weapon with super-high velocity bullet propulsion is established. The research results show that the technical scheme can greatly increase the initial velocity of the bullet with the peak pressure keeping nearly the same as the tradition barrel weapon. The research results can provide a theoretical foundation to significantly increase the initial velocity in barrel weapons using solid propellants, and have an important reference value to comprehensively increase the power of the barrel weapons.
