Abstract

An electromagnetic railgun having electrically conductive segments overlying but insulated from the rails. Switches are connected between each segment and its underlying rail. As a projectile and its plasma armature pass each segment, the switch associated with that segment opens, disconnecting the flow of current into the area behind the plasma armature. Without a source of current, parasitic current flow is prevented.

Solid-to-hybrid transitioning armature railgun with non-conforming-to-prejudice bore profile

Patent Solberg, Jerome Michael

An improved railgun, railgun barrel, railgun projectile, and railgun system for accelerating a solid-to-hybrid transitioning armature projectile using a barrel having a bore that does not conform to a cross-sectional profile of the projectile, to contact and guide the projectile only by the rails in a low pressure bore volume so as to minimize damage, failure, and/or underperformance caused by plasma armatures, insulator ablation, and/or restrikes.

Multiple stage railgun

Patent Hawke, Ronald S [Livermore, CA]; Scudder, Jonathan K [Pleasanton, CA]; Aaland, Kristian [Livermore, CA]

A multiple stage magnetic railgun accelerator (10) for accelerating a projectile (15) by movement of a plasma arc (13) along the rails (11,12). The railgun (10) is divided into a plurality of successive rail stages (10a-n) which are sequentially energized by separate energy sources (14a-n) as the projectile (15) moves through the bore (17) of the railgun (10). Propagation of energy from an energized rail stage back towards the breech end (29) of the railgun (10) can be prevented by connection of the energy sources (14a-n) to the rails (11,12) through isolation diodes (34a-n).

Repetitive resonant railgun power supply

Patent Honig, Emanuel M [Los Alamos, NM]; Nunnally, William C [Los Alamos, NM]

A repetitive resonant railgun power supply provides energy for repetitively propelling projectiles from a pair of parallel rails. The supply comprises an energy storage capacitor, a storage inductor to form a resonant circuit with the energy storage capacitor and a magnetic switch to transfer energy between the resonant circuit and the pair of parallel rails for the propelling of projectiles.

Multiple resonant railgun power supply

Patent Honig, Emanuel M [Los Alamos, NM]; Nunnally, William C [Los Alamos, NM]

A multiple repetitive resonant railgun power supply provides energy for repetitively propelling projectiles from a pair of parallel rails. A plurality of serially connected paired parallel rails are powered by similar power supplies. Each supply comprises an energy storage capacitor, a storage inductor to form a resonant circuit with the energy storage capacitor and a magnetic switch to transfer energy between the resonant circuit and the pair of parallel rails for the propelling of projectiles. The multiple serial operation permits relatively small energy components to deliver overall relatively large amounts of energy to the projectiles being propelled.

Omni-directional railguns

Patent Shahinpoor, Mohsen [9521 Avenida Del Oso NE., Albuquerque, NM 87111]

A device for electromagnetically accelerating projectiles. The invention features two parallel conducting circular plates, a plurality of electrode connections to both upper and lower plates, a support base, and a projectile magazine. A projectile is spring-loaded into a firing position concentrically located between the parallel plates. A voltage source is applied to the plates to cause current to flow in directions defined by selectable, discrete electrode connections on both upper and lower plates. Repulsive Lorentz forces are generated to eject the projectile in a 360 degree range of fire.
