一、概况今日的火炮发射药可谓种类繁多,令军方的采购员们无从选择。目前西方的一些研究机构研究的发射系统有好多种,比如:模式装药系统、单元装药系统、改进粒状药发射系统、液体发射药系统、各式电磁和电热发射系统。但是,由于经费的变化和敌方威胁的不断增长,使各种方案在必要性、可行性,承受能力和寿命等问题上的矛盾越来越大。在北约内部,人们强烈要求开发一种或更多种这类新技术,以抗 I. Overview Today’s artillery projectiles can be described as a wide variety, so that military buyers have no choice. At present, there are many launch systems studied by some research institutes in the west, such as pattern charge systems, unit charge systems, modified granular drug launch systems, liquid propellant systems, and various electromagnetic and electrothermal emission systems. However, due to the changes in funding and the ever-increasing threat from the enemy, the contradictions among the various programs on such issues as necessity, feasibility, affordability and life expectancy have been growing. Within NATO, there is a strong demand for the development of one or more of these new technologies
