远程多管火箭起始扰动研究

Rocket Initial Disturbance of LRMLRS

为了通过减小起始扰动提高远程多管火箭射击密集度,对简易控制远程多管火箭起始扰动进行了理论与数值仿真研究。应用发射动力学理论,对传统的起始扰动概念进行了扩展,推导出了简易控制远程多管火箭弹起始扰动方程。对某简易控制远程多管火箭在有控和无控发射方式下的火箭弹起始扰动以及密集度进行了仿真,仿真结果得到了试验验证。仿真结果表明起始扰动仍是影响某简易控制远程多管火箭密集度的主要因素,可为优化简易控制方式以减小起始扰动和提高射击密集度提供一定依据。

In order to improve the firing dispersion of Long Range Multiple Launch Rocket System（LRMLRS）by reducing the initial disturbance,the rocket initial disturbance of a simple control LRMLRS is theoretically and numerically researched.The traditional concept of the rocket initial disturbance is expanded by using a launch dynamics theory.The equations of the rocket initial disturbance of the simple control LRMLRS are developed.The rocket initial disturbance and the firing dispersion of the simple control LRMLRS in control and without control are simulated.The simulation results are validated by experiments.The simulation results show that the rocket initial disturbance is still the main influence factor for the firing dispersion of the simple control LRMLRS.The results can provide references for reducing rocket initial disturbance and improving the firing dispersion of a simple control LRMLRS by optimizing simple control.
