摘要
为提高防空制导炮弹的制导精度,针对一对舵翼鸭式布局的有控防空炮弹,分析了一对鸭翼周期平均控制力的形成机理,建立了基于周期平均理论的6自由度防空炮弹有控弹道模型,推导了操纵力对弹丸周期平均攻角的关系方程,研究了重力补偿所需大小的计算方法.计算仿真结果表明,在防空炮弹纵向平面内,控制力经重力补偿后,由重力引起的弹道偏差得到了改善.
In order to improve the guidance precision of anti-aircraft guided projectile, the principium of periodic average force was analyzed aiming at the projectile with a pair of canard. Based on periodic average force, the 6D ballistics model was built. The relation equation between control force and attack of angle was deduced, and the calculation means for gravity compensation was presented. The computational simulation shows that the error caused by gravity was reduced obviously after gravity compensation in portrait.
