【摘要】 电热化学发射中,烧蚀毛细管等离子体发生器的放电是电能转化为热能的重要阶段。目前,国内外的研究主要集中在对喷管式的毛细管进行实验和理论分析。但喷管式的毛细管却有其不可克服的缺点。因此,笔者提出了采用中心电弧式的毛细管,并从理论上对其进行了描述,同时针对一种通用的材料———聚乙烯在多种贮能条件下进行了放电实验研究,得出了一些规律性的认识。实验表明:中心电弧等离子体发生器在电弧稳定性以及能量转换等方面都有独特的优点。更多还原

【Abstract】 The discharge of ablation capillary plasma generator is an important energy conversion phase in electrothermal-chemical launch and at present the studies almost focus on injector capillaries. However the injector capillaries have some disadvantages. This paper brings forward a piccolo capillary and establishs a physical model. With numerical simulation and experiments, it is shown that the piccolo plasma generator has particular advantages in stability and energy conversion.更多还原
