摘　　要：针对远程火箭弹落点散布大的问题,探讨了一种以鸭舵实现火箭弹姿态稳定,并采用阻力机构进行纵向散布修正的复合控制方法。提出并分析了简易制导系统方案,建立了鸭舵-阻力环复合控制条件下的有控弹道模型,对启控点参数进行了合理设计。仿真结果表明,该制导方法能够有效地抑制由各种扰动因素引起的技术散布,可大幅提高远程火箭弹的射击精度。Aiming at the problem of large dispersion for long-range rocket,a combined control method was discussed,which can realize the attitude stabilization with canards and correct the range dispersion with drag device.The simple guidance scheme was proposed and analyzed.The controllable trajectory model was established,considering the control force of canards and drag brake.And the starting control point parameters were also designed properly.The simulation result shows that this guidance scheme is able to reduce the technical dispersion caused by various disturbances effectively and improve the fire accuracy of longrange rockets.
