传感子弹开伞高度的不同对其落地状态和落点精度有着很大的影响,为了确定传感子弹开伞高度,在建立伞弹系统弹道模型的基础上,利用Matlab/Simulink仿真平台,对伞弹系统的运动过程进行了仿真计算,计算结果与试验数据吻合较好,之后综合考虑风、装药号数以及射角等各种因素的影响,利用该仿真模型对传感子弹的开伞高度进行了仿真计算,计算结果表明:一号装药开伞高度应选择在175~250m范围内,六号装药开伞高度应选择在150~225m范围内。

The parachute deployment height of sensing reconnaissance submunition has great effect on its landing state and precision. To determine the deployment height of the sensing reconnaissance submunition, Matlab/Simulink simulation platform was used for the motion of parachute-bomb system. The results are in good agreement with the experimental data. And considering the wind, charge number and firing angel etc, the height of the reconnaissance submunition was simulated, the result indicate that the deployment height of 1# charge should be 175~250m, and that of 6# charge should be 150~225m. The method has some certain reference value for deciding the deployment height of other parachute landing submunition.
