In order to extend the fire range of the domestic Tear Bomb Emitter, its influence factors of fire range and muzzle velocity of projectile were analyzed theoretically, and the relationship between charge quantity, barrel length and muzzle velocity of projectile were analyzed quantitatively. A technical way of increasing charge quantity and barrel length was given to raise the muzzle velocity of projectile. Interior ballistic simulation was carried out by numerical simulation and the numerical recipes software MATLAB, and the rationality of charge quantity increase was validated. The balance design of the emitter was carried out by the parameterized entity model - building software Pro/Engineer after increasing the barrel length. The feasibility of both charge quantity increase and barrel length in- crease was validated by making use of the ball firing experiment. The research illustrates that both charge quantity in- crease and barrel length increase can improve muzzle velocity of projectile of the domestic Tear Bomb Emitter, and it also provides an accurate and practical method to extend the fire range of the emitter.
