滑翔增程弹箭滑控段弹体运动模式对增程效率的影响

增程技术是弹箭技术重点发展方向之一，而滑翔增程是目前采用的较为有效的ー种弹箭增程技术。阐述了滑翔增程弹箭的飞行过程，建立了滑翔增程弹箭的滑翔段弾道模型，在滑翔控制段弹体分别采用俯仰滑翔飞行和旋转滑翔飞行,分析了在滑'翔控制段弹体的两种运动模式对弹箭增程效率的影响。仿真结果表明：在滑翔控制段弹体釆用俯仰滑翔飞行，增程效率高，但在滚转控制过程中控制系统复杂，对舵机的要求高；在滑翔控制段弹体采用旋转滑翔飞行，增程效率较低，但整个控制过程中控制系统简单，对舵机的要求低。

Effect of Motorial Modes of Gliding Extended Range Projectile on Range Extended Efficiency

Increasing a range of projectile with gliding flight is a quite efficient technique. The flight process of gliding extended range projectile was explained. A ballistic model of gliding control segment was established. The pitching gliding flight and rotating gliding flight of the body were used in the gliding control segment. The influence of two kinds of motorial modes of the body on the extended range efficiency of projectiles was analyzed. The result shows that the extended range efficiency of the pitching gliding flight is higher, but the control System is complicated and the rudder requirement is higher in the course of the rolling control; the extended range efficiency of the rotating gliding flight is lower, but the control system is simple and the rudder requirement is lower in the course of the whole control.
