Abstract

Abstract: In order to apply high-efficient muzzle brake to a large caliber gatling gun system,the muzzlebrake efficiency is calculated based on the gas dynamic equation of supersonic airflow. A rigid-flexiblemulti-body model is established on the basis of rigid-flexible coupling dynamics modeling theory, and the dynamics simulation and exterior ballistic calculation are performed for the shooting of gatling guns withdifferent muzzle brakes on a light tripod. The results show that increasing channel angles can significantly improve the muzzle brake efficiency and reduce the recoil displacement and velocity,restrain the elasticdeformations of tripod and barrel, as well as improve the firing stability and density of gatling gun system.The effect of brake is weakened if the channel angles exceed 120毅.
