摘要
通过箔条的地面发射试验,测量了两种不同长度的箔条在不同初速条件下的最远抛撒距离和最大宽度,得到了箔条阻力系数与雷诺数之间的线性关系。试验结果表明:长箔条的阻力系数大于短箔条的阻力系数;当箔条的发射初速增加到一定值后,箔条的抛撒距离增加的很小。
Based on chaff ground projectile test,the longest release distance and the biggest width under different initial velocity of two kinds length of chaff were measured. The linear relation between chaff drag coefficient and Reynolds number are derived. Test result indicates, the drag coefficient of long chaff is larger than that of the short one, and the chaff release distance increases a little when the initial velocity reached a certain value.
