中文摘要：

为了优化燃料空气炸药（FAE）装置参数,采用高速运动分析系统,观测燃料云雾的分散过程,研究中心装药对燃料云雾体积的影响规律。试验结果表明,燃料空气炸药装置的中心装药起爆后,燃料开始分散,云雾体积逐渐增大。燃料云雾抛散过程和最终体积与中心装药有关,当中心装药能量较小时,燃料云雾最大体积随中心装药能量增大而增大,当中心装药能量达到临界值以后,燃料云雾的最大体积不再随能量增大而增大。

英文摘要：

In the dispersal of fuel mixture, a key technique in fuel air explosive weapons, concentration distribution and volume of fuel cloud are the main factors of explosion effect of a fuel air explosive device. The fuel/air cloud volume and consistency can be controlled by center high explosive charge in a fuel air explosive device. Fuel/air cloud dispersal processes of four kinds of center high explosive charges were introduced in this paper. The experimental results show that the cloud dispersal velocity varies from high to low and tends to zero. When the cloud dispersal velocity drops to zero, the volume of cloud reaches max. The max cloud volume relates to center high explosive charge and increases with the total energy when the total energy of center high explosive is lower. When the total energy of center high explosive reaches a critical value the max volume of cloud does not increases with the total energy. The conclusion has offered a basis for improving the cloud dispersal characteristic feature and detonation effects of FAE.
