摘要
为研究亚音速条件下燃料的动态抛撒特性,通过10 kg级样弹火箭撬动态抛撒试验,获取了270 m/s速度时燃料爆炸抛撒云团的形成过程,分析了亚音速条件下燃料动态抛撒云团形态及尺寸分布的变化规律,并与静态抛撒云团参数进行了对比。结果表明:亚音速条件下,燃料的动态抛撒云团呈现伞形分布,其半径较静态时减小了约15%,厚度较静态时增加了73%。
In order to study the dynamic dispersion characteristics of fuel at subsonic speed,the dynamic dispersion test of rocket sled with 10 kg dispersal device was carried out.The formation process of fuel explosive dispersion cloud at 270 m/s speed was obtained.The shape and size distribution of cloud under subsonic condition was analyzed,and the comparison with static dispersion cloud parameters was made.The results show that under subsonic conditions,the dynamic fuel dispersal cloud is umbrella shaped,its radius is reduced by about 15%and its thickness is increased by 73%compared with static state.
