Abstract:	Aiming at the problems of high recoil and high power consumption of external energy drive when the new high fire rate gatling gun is fired, a multifunctional muzzle device is designed, which utilizes the gunpowder gas energy to provide the high fire rate gatling gun with the function of recoil and rotation. Fluent software was used to simulate the muzzle device in three dimensional simulation. Based on the simulated muzzle flow field, the distribution of gunpowder gas in the muzzle and the formation process of shock wave are analyzed. During the simulation process, the force and side hole jet parameters of the muzzle device are monitored, and its recoil control efficiency is calculated to be 53.03%, and the average moment of rotate assist can be provided to be 1 442.17 N·m. A simplified model of recoil motion of the gatling gun is established to calculate the recoil motion characteristics of the gatling gun under the continuous firing state, and the results show that the maximum recoil resistance is reduced from 191 kN to 127 kN, and the maximum recoil displacement is reduced from 10 mm to 4.3 mm after the addition of the muzzle device.
