大气环境下箔条运动轨迹及箔条幕扩散模型

考虑空间大气密度、运动速度、阻尼系数参量对悬空箔条受力的影响,结合箔条自身属性及运动特性,建立了大气环境下箔条运动模型。在此基础上,依据布撒空中干扰走廊的应用实况,给出了箔条幕墙的生成想定与扩散模型,并对幕墙的长度、宽度、厚度、漂移速度、体密度及幕内箔条取向予以定量描述。仿真实例表明该模型能够更真实地反映箔条运动规律,为箔条干扰与抗干扰对抗研究提供实用基础。

Model of chaff motion trajectory and curtain wall diffusion in air enviromnent

The model of chaff motion is established on the basis of considering the influence of the space atmospheric density,velocity and damping coefficient on chaff and combining chaff self attribute and motion trait.Based on the applied situation of deploying the air jamming corridor,the formation scenario and diffusion model of the chaff curtain wall is established,and the related parameters,length,width,thickness,drift velocity,bulk density,and tropism of the chaff,are described quantificationally.Simulation instance shows this model can reflect the law of chaff motion,which can offer the applied basis for the research of chaff jamming and anti-jamming.
