为增加巡航导弹低空突防的概率,在离线规划好航迹后,要保证导弹以最小偏差沿航迹飞行.通过仿真发现,传统的角指令法存在航路点切换时导弹过载超过指标要求,导弹越过障碍物时有较大的过顶时间的问题.为解决这一问题,提出了一种导弹纵向和横侧向的航路导引方法和指令生成方法,并以某型导弹低空突防为例,设计了飞行控制律.通过地形跟随六自由度仿真,比较了两种航路导引方法对地形跟随性能的影响.仿真结果都表明:采用这种纵向和横侧向航路导引方法和指令生成方法以后,该型导弹的地形跟随飞行性能得到了明显提高.
In order to increase the probability of low-altitude penetration of cruise missiles, after the trajectories are planned offline, it is necessary to ensure that the missiles fly along the trajectory with the minimum deviation.Through the simulation, it is found that the conventional angle command method has the missile overload exceeding the target requirements during the waypoint switching, Over the obstacles when there is a large over-peak time.To solve this problem, a missile longitudinal and transverse side of the route guidance method and instructions generation method, and a missile miss-level as an example , And the flight control law is designed.Through the terrain following six degrees of freedom simulation, the influence of two route guidance methods on terrain follow-up performance is compared.The simulation results show that by using this method of longitudinal and lateral lateral guidance and instruction generation After the method, the missile’s terrain has been significantly improved flight performance.
