一种末段修正火箭弹落点精度研究

Study on the Precision of a Terminal Correction Rocket

提出了一种末段修正火箭弹的脉冲修正策略,研究了脉冲修正的落点偏差,分析了惯性测量装置的漂移引起的落点偏差,并对这两种偏差进行了计算机仿真。结果表明:新型惯性测量和脉冲发动机的应用能够在保证较小费效比的情况下,将火箭弹的误差减小到一个较小的量值。

In this paper, we put forward a correction method of pulse jet of a terminal correction rocket , study the deviction of fall point of the pulse jet correction rocket, analyze the fall point deviation caused by the drift error of IMU and analyze two deviations through simulation. The results indicate that application of new type IMU and pulse jet motor can reduce the fall point deviation of the rocket to a smaller one under the condition of ensuring smaller expense-effect ratio.
