摘　　要：风场是无动力滑翔弹飞行过程中的一项重要干扰因素。针对滑翔导弹的气动力模型和其在不同飞行时段的运动特点,建立了航弹的姿态控制模型和制导律模型。并在一定的初始投抛条件下,利用C++与Matlab飞行仿真软件混合仿真,对航弹的飞行参数进行了大量的计算和相应的6-D飞行轨迹仿真。提出了无动力飞行器的姿态控制方法和计算机软件实现仿真的技术途径。仿真结果表明风干扰是影响无动力滑翔弹控制系统稳定性和精度的重要因素。对于具有滑翔段的飞行器在实际设计中很有参考价值和工程实用价值。Wind field is one of the important disturbances to the flight process of unpowered gliding bomb.This paper,based on bomb＇s dynamic equations,sets up a model of guidance and control system with the consideration of wind disturbance.Flight parameters were calculated by considering the combination of release conditions and a certain wind field.It provides a method of guidance and control of unpowered vehicle and technology of computer simulation,and its results show that wind disturbance is an important factor affecting the stability and precision of missile system.The method is of reference value and practical engineering value in real application of unpowered vehicle.
