摘要:
火炮的后效期现象是一种比较复杂的非定常气体动力学现象。传统的后效期理论通常采用准定常假设 ,有些理论计算公式形式奇特 ,物理概念不清。该文对火炮后效期的理论计算公式作了系统研究 ,摒弃了准定常假设 ,求得了后效期膛内火药气体总动量变化率的解析解 ,得到了一套推理相对严谨、物理概念比较清晰的火炮后效期理论计算公式 ,包括后效期炮膛合力公式和一些后效期特征量计算公式。这些公式经实际应用检验 ,表明精度较好
Abstract:
Gas eject ion from gun muzzle is a more complex unsteady process. The quas-i steady assumption was generally used in traditional theories for the gas eject ion period. Some of the theoret ical formulas have st range forms, and the physical meanings of these formulas are v ague. T he theory of the gas eject ion period is systemat ically studied in this paper. The quas-i steady assumption is abandoned, and the analy tical solut ion of g as momentum variat ion in bore is deduced. Based on st ricter deduction, a series of theoret ical formulas for the g as ejection per-i od w ith specific physical meanings are obtained, including the theoretical formulas for the breech force and some characterist ic parameters for the g as ejection period. T hese formulas have been used in pract ice and good accuracy w as shown.
