本文对有源无源混合干扰弹的基本情况进行了简要说明,对自行设计的混合干扰装置进行了介绍,建立了无源干扰物质(箔条)在爆炸气流中的运动模型,对运动微分方程进行离散得到了计算方程。通过时间推进求解了模型,得到了每根箔条质心运动的速度-时间关系以及位置-时间关系,并且对最终形成的箔条云形状做了预判,与实际大致相符。
In this paper, the basic situation of active and passive hybrid jamming bomb is briefly described. The hybrid jamming device designed by ourselves is introduced. The moving model of passive interfering substance (chaff) in explosive gas flow is established. Discrete computing equations have been obtained. The model was solved by time advance, and the velocity-time relationship and position-time relationship of each foil centroid motion were obtained. The shape of the final chaff cloud was pre-determined, which was roughly in accordance with the actual situation.
