摘要: 为提高旋转稳定子母弹子弹药的散布精度,提出了一种自适应开舱方法。该方法通过对旋转稳定子母弹飞行过程的动力学分析,建立子弹药全弹道模型,并采用该模型对子弹药落点散布情况进行仿真分析。针对母弹飞行过程中开舱点前某位置处弹道诸元实际值与理论值的误差,通过仿真计算以分析各误差值对子弹药落点散布的影响。结合分析结果提出一种修正开舱点的母弹自适应开舱方案以提高子弹药落点散布精度,并推导出适合旋转稳定子母弹的开舱点修正公式。分析结果表明,使用该方法能将子弹药落点散布的横向密集度提高26.3%,纵向密集度提高53.8%.

Abstract: In order to increase the impact dispersion accuracy of submunitions, a method of self-adaptive cabin opening is put forward. A trajectory model of submunition is built based on the research on the flight dynamics of spin-stabilized shrapnel. The impact dispersion of subminution is simulated by using this model. According to the errors got from the theoretical and practical trajectory results of a certain ejection point of the shrapnel, the effects of the errors on the impact dispersion of submunition are analyzed through simulation comprehensively. With the help of the simulation results, a shrapnel self-adaptive cabin opening method with modified ejection point is proposed to improve the impact dispersion accuracy of submunition. A modified formula for the best cabin opening point of spin-stabilized shrapnel is deduced. The results show that the method used in this paper can be used to increase the impact dispersion of submunitions by 26.3% in horizontal and 53.8% in vertical.

Key words: ordnance science and technology, shrapnel, self-adaptive cabin pening, accuracy of impact dispersion of submuntion
