机载无源干扰诱饵的运动特性研究

摘要

It is found that the passive jamming decoy is mainly affected by the air force and gravity force on the consideration of the decoy' s self-attribute and the atmospheric environment in which it is located. Based on the analysis, the dynamics model and kinematics model of the passive jamming decoy are built. And its movement is got from simulation. The concept of equivalent sphere is given based on the chaff could and single chaff' s force analysis and the visualized scattering process can be seen from simulation.%考虑机载无源干扰诱饵自身的属性和其所处的大气环境,对其进行受力分析,发现无源干扰诱饵受空气动力和自身重力的影响较大.据此建立了无源干扰诱饵的动力学模型和运动学模型,仿真得出无源干扰诱饵的运动情况.在对箔条云受力和单根箔条受力分析的基础上,给出等效球的概念,在仿真中直观地得到了箔条云的散开过程.
