In order to keep submarine safety and stealthy in offensive mining used by the self-propelled mine, and to make full use of the high mining efficiency of the pneumatic unbalanced launcher, it is absolutely necessary to build the interior ballistics model of the pneumatic unbalanced launcher. So aiming at characteristics of the self-propelled mine, the launch process can be analyzed through simulation and the launch feasibility can be expounded and proved. The paper analyzed the fundamental principle and working process of pneumatic unbalanced launcher in different stages. By analyzing the structural characteristics of the pneumatic unbalanced launcher, this article built a mathematical model for launching course of the pneumatic unbalanced launcher by using control volume theory and following air work process. According to the typical parameters of the self-propelled mine and the launching depth, the important parameters of launching process, just like launching pressure, launching velocity and so on, were calculated so as to analyze the feasibility and safety of launching new self-propelled mine in large depth by the pneumatic unbalanced launcher. Results show the launching velocity and chamber pressure can satisfy the safety requirement. Launching new self-propelled mine by pneumatic unbalanced launcher is totally practicable.
