| 摘 要： | 在小口径发射装置上进行了以液体发射药为化学工质的电热化学发射实验研究，采用不同的装药结构及装药量改进内弹道性能， 可使弹丸获得超高速。对电能释放与化学能释放过程的合理匹配表明， 等离子体能够增强液体药的燃烧并影响压力变化曲线。通过等离子体射流与液体药装填方式的控制， 如采用环状装药结构， 可以增进等离子体与发射药的相互作用， 提高内弹道性能

| Abstract: | Experimental study of electrothermal chemical launching taking liquid propellant as chemical working media in small caliber launching apparatus was performed.In order to adjusting the interior ballistics performance different charge of propellant and mass were utilized.The projectile was accelerated to a hypervelocity of 2 677 m/s.The match between releasing of chemical energy and discharging power of electric energy was analyzed.It is indicated that the plasma could augmented the combustion effect of liquid propellant and affected the pressure curve.By the controlling of plasma jet and loading method of liquid propellant,such as ring shaped loading of propellant,could enhanced the match of the interaction between plasma and propellant,increased the interior ballistics performance. |
