| Abstract: |
| Firstly, this paper introduces the research significance of underwater gun weapon launches and the military needs are analyzed. Then, the commonly used launch methods of underwater guns are introduced, and their respective development processes are briefly described. The research progress on the interior ballistics of underwater launches is summarized. Combined with the characteristics of underwater gun firing problem, the formation mechanism of gas jet and the evolution process of related research are expounded. The research progress and corresponding typical wave system structure of the flow field at the muzzle of air gun and underwater gun are summarized comparatively. Finally, the scientific problems existing in the field of underwater gun firing and the future development trend are prospected. |
