Based on the principle of the metal storm weapon system and the shooting principle of in series and beforehand loading, the structure of a super-high firing rate weapon system was designed and analysed in this paper. Three types of structure were designed, the corresponding mathematical models of interior ballistic were established. In two cases of non-coupling and intensive coupling, three structures'numerical computing and analysis in the process of interior ballistic were carried out in detail respectively. After analysis and comparison of the results, one of the designs was chosen. Then, based on heat transfer and related theory the temperature field and thermal stress in two cases of non-coupling and intensive coupling were computed and analyzed using finite element method. The influence of the material strength, projectile location and seal ability by gunpowder gases under high temperature and high pressure in the shooting process were studied emphatically. Finally, some appropriate conclusions were obtained.The research of this paper is valuable to improve the rationality of structural design for super-high firing rate weapon system. The study of super-high firing rate weapons systems temperature field and thermal stress is the key of this paper. Active research carried on in this area is important and significant for realizing the rapid development of super-high firing rate weapons and effectively solving the problem of weapons systems heat-structures.
