Study On Interior Ballistic Characteristics Of The Multi-Gas Sources Ejection Power System

In this paper, the internal ballistics model of the multi-gas sources ejection power system is established, the internal ballistics characteristics are studied, and the launch process of a certain missile is calculated by using the internal ballistics equation, and the important parameters such as velocity and acceleration of the missile, pressure and temperature in the launch cylinder are obtained. Compared with the pure gas single power launch scheme, the multi-gas sources ejection power system can effectively reduce the missile overload, reduce the pressure in the launching cylinder and improve the energy utilization efficiency. The maximum acceleration of the missile is reduced by more than 50%, which makes the movement process of the missile more stable and the interior ballistic trajectory more accurate; the maximum pressure in the launch cylinder is reduced by more than 45%, which greatly improves the launch safety, and also provides conditions for the lightweight of the launch device.
