摘要
为考察攻角约束对直气复合控制的导弹实现越肩发射的影响,首先针对一个反作用喷气系统安装在尾部的敏捷导弹建立了俯仰通道四阶动态模型,然后利用高斯伪谱法获得时间-燃料最优解,并对不同攻角约束下的最优解进行了分析和比较。仿真结果说明攻角约束越严格,敏捷转弯过程的转弯半径越大,时间越长,燃料消耗越多。
In order to investigate the influence of the angle of attack constraint on the launch of the missile realized by the direct gas combined control, a four-order dynamic model is established for a missile which reaction-jet control system （RCS） is arranged in the tail. Then by utilizing Gauss pseudospectral method （GPM）, time-fuel optimal solutions are obtained, and the optimal results with different angle of attack constraints are compared and analyzed. The simulation results show that stricter angle of attack con- straint causes larger turning radius, longer time cost and more fuel consumption.
