某底部排气弹弹丸阻力计算方法研究

Study on Drag Calculating Methods about the Base Bleed Projectile

以某底部排气弹大量实弹射击数据和解算其底排内弹道的基础上，用多项式最小二乘法的经验回归方法拟合出该弹底阻减小率经验公式，作为研究设计同口径复合增程弹的基础。

On the basis of the Interior Ballistic calculation of base bleed projectile and a great deal of firing data,this paper draws up the empiric formula of the rate of reducing base drag by the way of the multinomial regression analysis to serve as the basis of designing the same diameter complex assisted projectile.
