Abstract

In order to explore the influence of liquid-column equilibrium on the firing stability of single-barrel weapons, the dynamic characteristics of the liquid-column equilibrium weapon are studied. By analyzing the launching process of a single-barrel weapon using the liquid equilibrium launch technology, the force model of the launching process of a single-barrel weapon is established. The simulation model of gas-liquid two-phase flow in the nozzle is established by using fluent fluid simulation software, and the influence characteristics of liquid working medium on the thrust of the nozzle are mainly analyzed; and the variation law of rifling lateral force of individual barrel weapon under the influence of liquid column balance body is analyzed.The results show that the liquid-column balance has great influence on the firing stability of the single-barrel weapon, and further optimization design is needed.

Key words： individual tube-shape weapon; liquid column balance; dynamics; steering force; thrust nozzle
