NATO角和飞板速度对平板装药干扰射流频率的影响

Effect of NATO Angle and Plate Velocity on Disturbance Frequency of Reactive Armor against Shaped Charge Jet

为研究射流轴线与飞板的夹角大小（NATO角）和飞板速度对反应装甲干扰聚能射流的影响，在分析飞板与射流作用的基础上，建立了计算飞板断续干扰射流频率的物理模型，利用此模型分析了NATO角以及飞板速度对干扰射流的影响，并进行了试验研究。研究结果表明，干扰频率在NATO角为40°-60°时会急剧增加，随着飞板速度的增加干扰频率变大。

The frequency calculation on the intermittent disturbance is of importance for the penetration calculation of the escaping jet and the design of anti-shaped charge jet. A physical model was presented based on the analysis of interaction process. The effects of north atlantic treaty organization （NATO） angle and the plate velocity on the disturbance frequency were discussed and compared with experimental results. Results show that the disturbance frequency increases drastically when the NATO angle changes from 40°to 60° , and increases with the plate velocity.
