Research on Average Windward Area Measuring System of Cannonball Fragment

采用二十面体方法的迎风面积测量技术作为不规则形状的炮弹破片平均迎风面积的测量方法,并以此设计出了破片迎风面积测量系统,为下一步的典型破片初速测量提供重要参数。详细论述了系统的检测原理、总体结构及数据处理系统。通过实验对系统的测量精度进行了验证,系统的测量精度完全满足破片面积测量精度要求:±5%。

The regular icosahedron measuring technique is used in measurement of anomalistic cannon-shot aver- age fragment windward area, and by this means, a kind of measuring system is designed. The average windward area is a very important parameter of typical fragment muzzle velocity measurement. The working principle, overall structure and the data processing system are described. The measuring precision of the system is verified by experiment, and it is less than the required： ±5%.
