摘要： A projectile is accelerated through a gun barrel in response to high pressure gas applied to the rear of the projectile in response to a high pressure plasma discharge. Plasma from the discharge flows transversely of the discharge into a chamber through multiple openings in a passage wall that confines the discharge. The high pressure, high temperature plasma flowing into the chamber causes an exothermic reaction of water and metal particles in a slurry in the chamber to produce high pressure hydrogen gas that flows longitudinally of the discharge against the rear of the projectile. To maintain the pressure of hydrogen gas acting against the projectile relatively constant as the projectile is accelerated down the barrel, electric power applied to the discharge increases substantially linearly as a function of time.

摘要： A plasma generator (44) for an electrothermal gun cartridge has elongated metallic rod and tube members (58,60) extending along a central axis thereof with the tube member (58) having at least one axial gap (62) and with an elongated annular insulator located between and in engagement with both metallic members to provide support therebetween as an electrical voltage generates an electrical arc at the axial gap to provide a plasma that ignites a propellant (46). Different embodiments of the plasma generator have a plurality of the axial gaps (62) located along the tube member (60) and are constructed for both simultaneous and sequential firing with fuses (74) controlling the timing. Helically extending member portions (78) provide rotation of the electrical arc and hence the plasma generated to distribute it for ignition of the propellent (46).
摘要翻译：一种用于电热枪筒的等离子体发生器（44）具有沿着其中心轴线延伸的细长金属杆和管件（58,60），管件（58）具有至少一个轴向间隙（62），并具有细长环形绝缘子位于两个金属构件之间并且与两个金属构件接合以在它们之间提供支撑，因为电压在轴向间隙处产生电弧以提供点燃推进剂（46）的等离子体。等离子体发生器的不同实施例具有沿着管构件（60）定位的多个轴向间隙（62），并且被构造成用于控制时序的熔丝（74）的同步和顺序点火。螺旋延伸构件部分（78）提供电弧的旋转，并因此提供产生的等离子体，以分配它以点燃推进器（46）。
