复合增程弹火箭助推段弹道数据处理方法

THE PROCESSING METHOD OF ROCKET-ASSISTED TEST DATA FOR ROCKET-ASSISTED AND BASE-BLEED PROJECTILE

以6自由度弹道方程为换算模型,采用最小二乘法拟合复合增程弹火箭助推段弹道的数据,换算出了火箭发动机在飞行中的推力～时间曲线.拟合结果可直接用于复合增程弹弹道分析计算.

In this paper, the method of fitting the rocket-assisted trajectory data by Doppler Radar is presented from a free-flight test of rocket-assisted and base bleed projectiles. With the method, the thrust-time curve of rocket is computed from free-flight test data. With the curve, the rocket-assisted trajectory of the projectiles can be calculated and analyzed.
