摘要
该文从分析影响超高速火炮初速的理想工质入手,根据国外超高速发射技术的最新实验研究成果,介绍一种吸收电热化学炮、轻气炮优点的新型火炮装置———电热化学轻气炮。由于该炮在电热化学炮的基础上加入轻质气体这一理想工质,因而能大大改善弹丸后部的压力分布,提高火炮弹丸的初速。该文以内弹道学原理为理论基础,介绍了这种新型火炮装置的工作原理,并建立了其内弹道物理数学模型,为这种超高速射弹装置的设计和实际应用提供了理论依据。
According to the achievements in resent research abroad, this paper begins with the ideal gas in hypervelocity projectile and introduces a new type Electrothermal Chemical Light Gas Gun, which has the merits of both conventional Light Gas Gun and Electrothermal Chemical Gun. Because joined light molecular weight gas in Elctrothermal Chemical Gun, the pressure distribution in projectile base is improved and the projectile velocity enhanced. Based on interior ballistic physico mathematical theory, the gun's principles are described and its interior ballistic models are also established,laying theoretical basis of design practical use of the hypervelocity projectile.
