Influence of Accelerator Eccentricity on Ballistic Missle Firing Accuracy

该文建立了在发射点重力惯性坐标系内的视加速度误差模型。在导弹弹体干扰运动和控制装置数学模型的基础上,应用面向对象技术建立了计算机仿真模型,实现了导弹全弹道六自由度仿真,仿真结果得到了实际飞行试验验证。该文得出加速度表安装位置不在质心处影响导弹落点偏差的结论,该结论对于下一步提出误差修正方法奠定了基础,对于提高弹道导弹射击精度具有重要的意义。

Apparent acceleration error models are established in gravity interial coordinate at launching point. Based on the mathematical models of the disturbed movements and the control equipments of the missile body, simulation models are set up by applying object-oriented technology. A six-degree-of-freedom simulation in full trajeeto~ is made, and the simulation results are validated by an actual flight test. The conelusion that the accelerator eccentricity leaves influence on the firing accuracy of ballistic missiles is made, which lays a foundation for the error correction methods in further research and has significance in improving the firing accuracy of ballistic missiles.
