| 摘 要： | 通过力学分析与计算,探索了燃料空气炸药(FAE)壳体与燃料在发射过程中的相对运动特性,指出了在发射过程中,在距离战斗部顶端一定范围内,壳体与燃料不但会存在相对运动,而且不同层位处的燃料也存在相对运动,这是FAE战斗部在发射过程中的特有现象.研究结果表明,燃料在战斗部中的位置对壳体与燃料之间的相对运动影响较大,而燃料与壳体间的摩擦系数对其影响较小.

| Abstract: | The relative characteristics of motion of the fuel and shell upon launching is analyzed. By means of mechanical analysis and calculation, it is proposed that relative motion exists not only in the ranges between the fuel and shell of the warhead, but also in the fuel in different positions. The result of study indicates that the position of the fuel in the warhead has a marked influence on the relative motion, while the frictional coefficient between the fuel and shell has less influence upon it. |
