摘要
以相似理论为基础,根据经典内弹道理论提出了完全模化的微分方程分析方法,推导出了模型实验的相似准则。针对枪炮射击中不同火药及药形的特点,讨论了相应的近似模化方法,得到了具有普遍意义的弹道相似公式。最后,通过实验验证了理论的正确性。
In the paper, based on the similarity theory and the classical interior ballistics theory, the absolutely modeling method of differential equations is derived, similarity laws of modeling experiments are deduced. According to the different kinds of guns, different shapes and characters of gunpowers, a corresponding method of approximate model is discussed, the similar formula of ballistics with popular sense are reached. The results of experiments are in good agreement with the predictions.
