论证了点火时间散布对增大射程减小散布的重要性.提出了底部排气弹的底排装置点火性能的物理意义。指出了利用底排时阻力曲线确定点火时间是比较科学的方法,它反映了底排装置工作的实质性问题。分析了影响点火性能的因素. 利用外弹道学理论导出了平均点火时间与点火时间散布对底部排气弹射程与射程散布影响的计算公式.利用这些公式可以确定底排装置合理的点火时间与点火时间散布.本文具体计算了155mm、130mm、122mm底部排气弹的合理点火时间与点火时间散布。根椐上述理论对底排装置的设计提出了具体要求。
It is demonstrated that the distribution of ignition time is important for increasing the range and reducing the dispersion, and the physical meaning of the ignition performance of the bottom row of bottom exhausting units is proposed. It is pointed out that it is a more scientific method to determine the ignition time by using the resistance curve of the bottom row, which reflects the substantive problems of the bottom row device. The factors that affect the ignition performance are analyzed.The calculation formulas of the influence of the average ignition time and ignition time dispersion on the bottom exhaust projectile range and range dispersion are derived by using the external ballistics theory.These formulas can be used to determine the reasonable ignition time and ignition Time distribution.This article specifically calculated 155mm, 130mm, 122mm bottom exhaust bombs reasonable ignition timing and ignition time spread. Based on the above theory, the design of the bottom row device is put forward specific requirements.
