The pneumatic weapon has broad application prospects with advantages of simple structure of ammunition and controllable launch energy.The working principle of a kind of compressed air-driving weapon was proposed here. Based on the theories of gas dynamics and Hertz contact,the model of its variable mass thermodynamic process and the friction force model were established,and the dynamic model of its launching process was built.With MATLAB /Simulink,the numerical simulation solutions to the state parameters of inner gun-barrel gas and the motion parameters of the projectile were obtained under the condition of a constant pressure of air supply.Furthermore,the effects of compressed air pressure changes and structure parameters on the launching process were analyzed.The results have great theoretical significances to guide the research and design of compressed air-driving weapons.
