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： An electromagnetic cylindrical projectile mass launcher and a method of operation is provided which includes a cylindrical projectile having a conducting armature, a cylindrical barrel in which the armature is received, a plurality of electromagnetic drive coil stages, a plurality of pulse energy sources, and a pulsed power arrangement for generating magnetic pulses forming a pulsed magnetic wave along the length of the launcher barrel. The pulsed magnetic wave provides a propelling force on the projectile along the drive coil. The pulsed magnetic wave of the drive coil stages is advanced along the armature faster than the projectile to thereby generate an induced current wave in the armature. The pulsed generation of the magnetic wave minimizes electromagnetic heating of the projectile and provides for smooth acceleration of the projectile through the barrel of the launcher.
