摘　　要：通过对不同厚度壳体的速度和动能进行理论分析,给出了壳体对燃料抛撒的影响规律;同时开展了不同厚度壳体的云爆装置试验,得到了装置威力与壳体厚度的关系。研究结果表明:采用薄壳体,并加强壳体与端盖的连接强度,可以提高中心抛撒药能量的利用率,进而提高一次起爆型燃料空气弹(SEFAE)的威力,试验结果与理论分析结果一致。Based on the theoretical analysis of the SEFAE outer shell velocity and kinetic energy with different depths,the influence of the shell on the dispersed fuel was obtained.The relationships between the damage power and the thickness of the shells were obtained by different SEFAE explosion experiments.The theoretical and experimental results show that the TNT equivalent of the SEFAE and the utilization rate of the center charge can be improved by using the thinner shell and increasing the connection strength between the shell and the end cover,in which the experimental results were in agreement with the theoretical results.
