远程火箭弹简易控制方法

通过数值仿真分析了弹道风、质量偏心、推力偏心、初始扰动等各种扰动因素引起远程火箭弹落点技术散布的机理,指出火箭弹落点散布主要来源于主动段,且主动段终点速度矢量的方向散布是造成落点散布的关键.在此基础上,提出了一种简易控制方法.该方法通过稳定火箭弹主动段姿态,减小了火箭弹主动段终点速度矢量的方向散布,抑制了各种扰动因素引起的技术散布,提高了远程火箭弹的射击密集度. 该方法具有控制效果好、系统简单、易于实现等一系列优点.

Unsophisticated Control Method for Long-Range Rockets

With numerical simulation, reasons of technical dispersion for long-range rockets resulting from various factors of disturbance are analyzed. The disturbances are mainly due to trajectory wind, mass misalignment, thrust misalignment, disturbance at launch, etc. It is pointed out that dispersion results mainly from the power-flight phase, especially from the direction dispersion of the velocity vector at the end of the power-flight phase. Based on this, an unsophisticated control method is proposed to reduce the technical dispersion and to improve the density of delivery. It is realized through the stabilization of attitude of the rocket at the power-flight phase directly, and reducing the direction dispersion of velocity vector indirectly. The method is simple in its system configuration, convenient for use and easy to realize.
