RAIL GUNS

Electromagnetic gun

An electromagnetic gun comprises a barrel for containing and directing an electrically conductive projectile and a plurality of inductors which are arranged in series relationship along the barrel so as to create magnetic fields which accelerate the projectile along the barrel. Each inductor is associated with a pair of rail electrodes within the barrel bore which, when bridged by the projectile, short circuit their associated inductor to provide additional acceleration of the projectile.

Electromagnetic launcher with improved rail energy recovery or dissipation

An electromagnetic projectile launcher is provided with muzzle circuitry which increases the rate of dissipation of inductively stored rail energy following the launch of a projectile and can be used to recover a portion of that stored energy for use in successive launches. The muzzle circuitry includes a pair of conductors which lie adjacent to the projectile launching rails and conduct current in a direction which is opposite to the current flow in the projectile rails. These conductors may be connected to a pulse transformer to increase the post-launch current of an inductive energy storage device. In an alternative embodiment, a capacitive muzzle circuit is used to store the inductive rail energy and inject current into the projectile launching rails during the launch of a successive projectile.

The thermal management system utilizing the reserve fuel from the aircraft to create thermal capacitance such that the instantaneous capacity of the cooling system to remove heat from the aircraft may be sized less than the rate of heat generated by the pulsed load (e.g. laser, radar, rail gun etc.) The reserve fuel is maintained at a temperature in a reservoir and cooled via a cooling system.

ELECTROMAGNETIC FIRING METHOD AND DEVICE

PURPOSE: To suppress generation of parasitic arc by providing first and second conductive current feed rails arranged contiguously to respective launcher guide rails while being connected electrically therewith at the muzzle such that the flux is coupled substantially the guide rail. CONSTITUTION: When a switch 48 is closed, a current flow from a current feed rail 36 through a launcher guide rail 30 to a fuse 53 which is thereby blown out to generate an arc or plasma thus driving the bottom plate of a projectile and a launcher 52 along the rails 30, 31. Since no current flow through the back side of the rails 30, 31, i.e., between B and C, voltage drop across a resistor can be eliminated. Since contribution of ohmic voltage drop to the voltage between the rails 30, 31 is zero, possibility of arc regeneration arc due to parasitic capacity can be suppressed significantly between B and C after passing the launcher 52.

Electromagnetic projectile launcher

An alternator for repetitive pulsing of an electromagnetic projectile launcher is provided with a stator structure having at least one pair of single layer concentric coil portions which are electrically connected in parallel. A rotating magnetic field induces a voltage in these coil portions without producing circulating currents. The alternator is connected through a switch to a pair of genrally parallel conductive projectile launching rails and a sliding conductive armature between the rails. By causing the switch to conduct at a predetermined phase angle, the voltage across the launching rails can be reduced to zero as the projectile leaves the rails. Where a succession of projectiles is to be fired, the phase angle at which the switch begins to conduct is controlled in order to achieve a substantially constant muzzle velocity for each projectile while minimizing the rail voltage as each projectile exits the rails.

Alternator driven electromagnetic launching system

A superconducting single phase alternator is connected by a circuit breaker across the breech ends of a pair of conductive launching rails. At a predetermined point on the alternator voltage wave a projectile establishes a current path between the rails to initiate a transient, sinusoidal current pulse effective in accelerating the projectile along the rails. A switch is actuated in response to the projectile exiting the muzzle ends of the rails to impose a short circuit across the rails. The circuit breaker disconnects the alternator from the rails as the current pulse goes to zero. The system provides higher launcher efficiency and reduced muzzle flash with minimum barrel length penalty.

MULTIPLE STAGE MAGNETIC RAILGUN ACCELERATOR

Multiple Stage Magnetic Railgun Accelerator Abstract A multiple stage magnetic railgun accelerator (10) for use as a projectile launch device by 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 (14) 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). Propagation of energy from an energized rail stage back towards the breech end of the railgun can also be prevented by dividing the rails (11,12) into electrically isolated rail sections (11a-n, 12a-n). In such case apparatus (55a-n) is used to extinguish the arc at the end of each energized stage and a fuse (31) or laser device (61) is used to initiate a new plasma arc in the next energized rail stage.

A device and method to accelerate solid metal slugs to high speeds. In one embodiment, a large electric current is passed through an outer cylindrical metal tube enclosing in part a metal slug, a central electrode, and a conducting tail coupled at opposite ends to the. metal slug and the central electrode.

The electromagnetic railgun using dielectric break down

The present invention relates to an electromagnetic railgun using insulation breakdown. More specifically, the present invention relates to a railgun which is able to discharge an armature by providing electromagnetic force for breaking down the insulation after placing a rail apart from the armature for a certain distance for reducing frictional force between the rail and the armature. According to the present invention, the railgun comprises: a pair of conductive rails apart from each other for a certain distance; an armature; an insulation breakdown unit; and an acceleration means. The armature is placed between the pair of conductive rails by being apart from the conductive rails for a certain distance to be insulated from the conductive rails.

The acceleration means is charged with high energy in order to provide the high energy to the conductive rails for accelerating the armature in a direction of an axis of the conductive rails by generating Lorentz force when electricity flows between armature and the conductive rails. According to the present invention, even if the armature and the conductive rails are apart from each other for a distance, the insulation breakdown unit breaks down the insulation between the armature and the conductive rails and electricity flows between the two. Accordingly, the armature can be accelerated by the acceleration means.

Electromagnetic projectile launcher

An electromagnetic projectile launcher (commonly referred to as a ''railgun'') consists of an electrical direct current power supply, two parallel rails (52), and a switching armature (54) releasably linked to a projectile armature (56), each armature being slideably located in mutually parallel channels between and along the length of the rails. The rails are each provided with two overlapping conductive zones along their length, the first zone (60) being electrically connected to the power source and in electrical contact with the switching armature in its start position. In operation, electromagnetic forces induced by the power supply propel the switching armature (54), and hence the projectile armature (56) linked to it, along the rails from the start position until the projectile armature comes into electrical contact with the second conductive zone (62). Thereafter the switching armature travels to a position where it is eliminated from the power supply circuit to prevent it remaining a resistive element in the circuit, the link between the two armatures is broken, and the projectile armature (56) is accelerated through the second zone (62) to its launch velocity to launch the projectile (72). The overlap of the conductive zones (60, 62) reduces the tendency for arcing to occur at the trailing edge of the switching armature (54) as it is eliminated from the circuit.

Arc length and/or plasma volume is reduced by conductive assemblies adjacent to the arc driving faces.
