摘要： A high pressure pulsed gas source for accelerating a projectile along a gun barrel comprises a structure including a high voltage electrode for establishing axial electrical discharges in corresponding axial gaps behind an outlet where the projectile is located. Plasma flows at right angles to the discharges into a propellant mass that is converted into a high pressure component of the gas pulse. The gaps are arranged so that after the projectile moves away from its initial position and is in the barrel, power applied to the plasma via gaps close to the outlet is greater than power applied to the plasma via gaps farther from the outlet. To avoid damage to the gun, the gaps are arranged so power applied to the plasma is substantially the same in the discharges when plasma is initially produced. The gaps include walls that are eroded differently by the discharges so gap walls close to the outlet erode faster than gap walls farther from the outlet. The propellant mass includes a solid fuel and an oxidizer that do not react at ambient conditions. A portion of the fuel abuts the structure and the fuel and oxidizer are vaporized and elevated to a sufficiently high temperature by the plasma as to produce an exothermic chemical reaction resulting in derivation of the high pressure gas pulse that is supplied to the projectile. The axial gaps are arranged so that the power applied to the plasma via gaps close to the projectile causes initial vaporization of the fuel closest to the projectile prior to vaporization of the fuel farther from the projectile and progressive vaporization of the fuel farther from the projectile.

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： An electrical power feed assembly (12) for supplying high current to an electrothermal gun has first and second electrical connectors (38) and (42) with associated contact portions (40) and (44) for engaging and plastically deforming first and second side contacts (20,22) on a cartridge (14) to provide firing while maintaining the electrical contact without any arcing. The first connector (38) has a curved contact portion (40) that provides an interference fit to plastically deform the first contact (20) and establish the electrical contact as the cartridge (14) is inserted into the gun. The second connector (42) has a pair of curved knife edges (48) that engage and plastically deform the second contact (22) of the cartridge to establish and maintain the electrical contact under spring action of the second connector and by operation of a cam mechanism (50) of a breech block (26) of the gun. The cartridge (14) has its first and second contacts (20,22) made of a relatively soft material, copper and solder preferably, and has the contacts provided with annular shapes that are engaged by the contact portions (40,44) of the first and second connectors (38,42).

摘要： A pulse forming network, responsive to a DC power supply, supplies predetermined current waveforms to a load in response to commands from a programmed source. Plural inductors are connected to switches responsive to commands from the programmed source. The switches are controlled to couple the inductors to the DC source to charge the inductors to a predetermined current level that is maintained substantially constant. The predetermined current level in each inductor is supplied to the load by switches controlled by the programmed source so that during successive intervals the predetermined constant current levels from differing numbers of the inductors flow from the inductors to the load. The inductance of each inductor, the load impedance and the duration current is supplied to the load by the inductors are such that the predetermined current level supplied by each inductor to the load is maintained relatively constant.
