Abstract:	A mathematical and physical model of the muzzle flow field of the impact reaction muzzle brake is established, and the numerical simulation is carried out. The structure and flow parameters of the muzzle flow field are calculated by using a variety of governing equations and K Epsilon model, and by using dynamic grid technology. The development law of the muzzle flow field of the single impact muzzle brake and the impact reaction muzzle brake is revealed by comparing the wall and bore forces of the single impact muzzle brake, and its advantages compared with the impact muzzle brake are shown. When the impact reaction muzzle brake is fired, the cross section pressure of the back side channel outlet is obviously higher than that of the front side channel outlet. Compared with the impact muzzle brake, the resultant force of the gun bore is less than 1/3, and the resultant force of the wall is less than 1/4. The numerical simulation results can provide a necessary reference for the structural design and optimization of this type of brake.
