激光制导炸弹偏转投弹方式与投放域的研究

On Deflected Bomb-Dropping and Releasing Areas of Laser-Guided Bombs

激光制导炸弹是一种无动力可控武器,根据这种特性,提出了偏转投弹的作战方式,即投弹时炸弹的速度在水平面的投影与弹目线在水平面内的投影存在一个夹角(即偏转角)。这样有利于载机投弹后迅速逃离敌方防空区域,从而提高载机生存率。首先,建立了激光制导炸弹的六自由度模型;然后,对激光制导炸弹的六自由度模型和控制系统在VC环境中进行了仿真试验;重点研究了偏转投弹的弹道以及在不同条件下偏转投弹与投放域(即攻击区)的关系;最后,对仿真结果做了对比,并从炸弹飞行时间、偏差、能量各方面分析了原因,结果表明此攻击方式的可行性。

The laser-guided bomb is a kind of unpowered controllable weapon. An attacking mode of deflected bomb dropping was proposed based on its properties, i. e. , there is an angle （called deflection angle） between the projection of the velocity and the projection of line-of-sight in the horizontal plane. By use of this bomb-dropping mode, the carrier can get away from the area of air defense very easily and increase its survival probability. We estabilished the 6-DOF mathematical models of laser-guided bomb, and made simulations for the models and control system of laser-guided bombs in VC environment. We also studied the trajectory of deflected bomb dropping and the relationship between deflected bomb dropping and the releasing areas under different conditions. Finally, simulation and experimental results were analyzed from the aspects of flight time, deviation and power of the bombs. The results show the feasibility of the proposed mode.
