Aiming at the problem that the aiming accuracy is affected by recoil force during the launching of gas gun,the main size parameters and their variation range of muzzle brake are determined based on the recommended values of weapon standard,and a first-class muzzle reaction muzzle brake suitable for Φ50mm caliber is designed.The braking efficiency of the brake is analyzed theoretically,and the effects of test parameters such as high-pressure air chamber pressure,projectile mass,side hole inclination angle,and side hole diameter on the braking efficiency are obtained,and the braking efficiency is verified by finite element flow field simulation.
