某型多管火箭炮射击间隔优化研究

为提高某型多管火箭炮火力密度,对其射击间隔进行优化研究。首先,建立某型多管火箭炮刚柔耦合模型,获得定向器管口动态响应,计算火箭弹起始扰动;然后,求解火箭炮外弹道方程,采用数理统计方法得到多管火箭炮密集度估计值;其次,基于Lanczos法对多管火箭炮进行模态分析,结合火箭炮管口动态响应确定新的射击间隔;最后,将新射击间隔输入动力学模型计算,结果表明在不影响射击密集度的基础上,新的射击间隔缩短发射时间21.4%,有效地提高了多管火箭炮火力密度。

Optimization Research of Firing Interval for MLRS

To improve firing density level of MLRS,optimization research of firing interval is applied. Firstly,the rigid-flexible-coupling model of MLRS is built to obtain the dynamic response of the launch guider muzzle and the rocket initial disturbance is calculated. Secondly,the equation of exterior ballistic is solved and the estimate of dispersion is obtained with mathematical statistic method. Thirdly,modal analysis for MLRS is carried out based on Lanczos algorithm and the new firing interval is proposed combined with the dynamic response obtained above. Finally,substitute the new firing interval into the model of MLRS,the results show that the new firing interval shorten the firing time by 21.4%and improve the firing density effectively without affecting the dispersion of the MLRS.
