摘　　要：通过建立制导航空炸弹的全系统模型,对弹的总体性能(包括飞行轨迹、可攻击区及对随机干扰的敏感性)进行飞行数值仿真研究。该系统模型包括:考虑各种随机干扰(如风场和气动特性系数误差等)条件下的六自由度数学模型、控制系统等模型。最后得出结论:制导航空炸弹的滑翔距离和可攻击区的范围随升阻比的增大而呈非线性增大,其滑翔距离沿随机风场方向的变化而明显变大或减少,其可攻击区形状沿随机风场的方向而扩展或收缩或飘移等。This paper simulated the whole guided control system and researched the characteristics such as the trajectories, attack zones and sensitivity to random obstacles of guided aerial bomb by the controlled flight numerical simulation based on the whole system model of the guided aerial bomb. The system model includes 6-D mathematical model considering some kinds of random obstacles, control system model and so on. Finally the conclusion was gotten as following： the gliding distance and attack zone of the guided aerial bomb become larger with the increase of the lift-drag ratio. The gliding distance become larger or smaller and the attack zone is re-shaped such as expanding or shrinking or flapping with the different directions of wind field.
