航空制导炸弹弹着角约束下对地全向攻击范围研究

Research for Omni-directional Attacking Zone of Homing Bomb with Terminal Angle Constraints

利用虚拟位移方法推导得出一种弹着角约束下制导炸弹变结构导引律。通过对典型投弹高度下制导炸弹对地全向攻击范围的研究发现,采用该制导律的制导炸弹在一定投放条件下具备全向攻击能力,尤其是采用大倾角小速度投放时,地面攻击范围较广,攻击区域内不存在盲区,将有助于提高制导炸弹对投弹位置误差和目标机动引起位置偏差的适应能力。

Using virtual displacement to deduce variable structure guidance logic with terminal angles constraints for homing bomb. The simulation results show that the bomb could impact the target accurately with specified direction with the designed guidance logic omni-directionally. It found that the homing bomb using the designed guidance logic has the omni-directional attacking ability in some releasing conditions, and the effective impact zone is large. This guidance logic could improve the adaptability of homing bomb to the deviation of releasing point and location of target.
