反应装甲爆轰阶段对射流干扰机理的研究

对射流与反应装甲相互作用的机理进行了分析和研究,建立了反应装甲在爆轰阶段干扰射流的数学模型,对“卵石模型”进行了简化和进一步定量化,推导了反应装甲运动的前、后板栏截射流的周期公式,提出了射流受反应装甲干扰后的后效穿深及干扰效率的计算方法,并与实验进行了对比．

A Further Study of the Disturbance Mechanism on Jets Caused by Reactive Armors

The mechanism of interaction between a reactive armor and an incoming jet is further studied in the paper. A mathematical model for the disturbance upon the jet induced by the reactive armor during detonation is developed. The quantitative "Pebblestone model" is further simplified and quantized. Formulas for the computation of the period of forward-moving and backward-moving plates intercepting the incoming jet are derived. Methods of computation of the jpenetration depth of jet after disturbance and that of the disturbing efficiency are provided, and a comparison with the experimental results is undertaken.
