摘 要:炮口速度及转速对航空火箭弹的立靶密集度有非常重要的影响。为了提高航空火箭弹的立靶密集度,文中以常规火箭弹的散布理论和外弹道理论为基础,对各随机因素进行分析,建立符合其特征的数学模型,运用蒙特卡洛法进行数学仿真,研究不同炮口速度与转速对航空火箭弹立靶密集度的影响,结果表明提高炮口速度有利于提高立靶密集度,而炮口转速则需要控制在合适范围内,此结果对今后工程运用提供了理论参考。The muzzle velocity and the muzzle rotating speed had very important influence on the vertica target dispersion of airborne rocket. In order to improve the vertical target dispersion of airborne rocket, base on the dispersion theory and exterior ballistic theory of conventional rocket, the random factors were analyzed to establish the mathematical model in line with its characteristics. By using the Monte Carlo method for mathematical simulation, the influence of different muzzle velocity and muzzle rotating speed on the vertica target dispersion of airborne rocket was studied. The results showed that increasing muzzle velocity was helpful to improve the vertical target density, while muzzle speed needed to be controlled within the appropriate range. This conclusion provided theoretical references for future engineering applications.
