远程变后掠翼巡航导弹多任务弹道设计及仿真

为研究适配变后掠翼巡航导弹多任务飞行的弹道设计问题,将导弹飞行过程分为爬升、巡航、下滑、盘旋和攻击5个飞行阶段。为了使导弹实现快速平稳的爬升和下滑,并顺利地转入巡航和盘旋阶段,弹道高度采用指数形式的程序飞行高度指令函数,并根据导弹运动方程,解析出高度指令函数关键参数的选择公式; 盘旋段采用覆盖作战区域的圆形弹道,偏航过载指令由与作战区域面积相关弹道曲率得出; 巡航段采用等高飞行直线弹道,攻击段采用自动寻的导引。弹道仿真结果表明,所设计的多任务弹道及指令合理,满足多任务飞行和高精度制导要求。

Multi-task Trajectory Design and Simulation for Long-rangeSwing-wing Cruise Missile

To study the trajectory design for the multi-task flight of long-range swing-wing cruise missile(SWCM),the flight process of cruise missile was divided into five phases such as climbing phase,cruise phase,glide phase,hovering phase and attack phase. In order to make the missile climb and glide rapidly and placidly,and to cruise and hover successfully,the exponential altitude functions were applied. According to the motion equation of missile,the calculation formulas for the key parameters were obtained. The hovering phase was regarded as circular trajectory covering battlefield,and the yaw overload instruction was obtained according to trajectory curvature correlating with the area of battlefield. The cruise phase was considered as linear trajectory with equal height; the homing guidance was applied for attack phase. The simulation results show that the designed trajectory is reasonable,and it satisfies the requirements of the multi-task flight and precise guidance.
