摘　　要：为探讨中心抛撒结构和复合抛撒结构对燃料抛撒的影响,通过80kg级FAE燃料抛撒试验,获取了两种抛撒结构下的燃料扩散特性及云雾参数。结果表明:与中心抛撒结构相比,采用复合抛撒结构时云雾形态更优,云雾直径较前者增益10.6%~14.6%,云雾厚度较前者减小18.8%~27.0%,云雾平均浓度与前者相当;复合抛撒结构端部抛撒药与中心抛撒药的质量比对抛撒产生一定影响,针对本文中的试验装置,其最佳质量比在18%左右。In order to investigate the influence of central and composite dispersal structures on fuel dispersal,using the dispersal test of 80 kilogram FAE fuel,the fuel diffusion law and cloud parameters of the two dispersal structures were obtained.The results show that:compared with the central dispersal structure,the cloud shape is better when the composite dispersal structure is used,the diameter of cloud is increased by 10.6%to 14.6%,the thickness of cloud is reduced by 18.8%to 27.0%,the average concentration of cloud is similar to the former;the mass ratio of the end explosive to the center explosive has a certain influence on the dispersant,for the test device in this paper,the optimum mas ratio is about 18%.
