By definition, if a current of one ampere flows in a pair of ideal infinitely long parallel conductors that are separated by a distance of one meter, then the magnitude of the force on each meter of those conductors will be exactly 0. Archived from the original on 12 February Please help improve this section by adding citations to reliable sources. Railguns have a number of potential practical applications, primarily for the military. In principle, if railgun power supply technology can be developed to provide safe, compact, reliable, combat survivable, and lightweight units, then the total system volume and mass needed to accommodate such a power supply and its primary fuel can become less than the required total volume and mass for a mission equivalent quantity of conventional propellants and explosive ammunition.

A plasma railgun is a linear accelerator and a plasma energy weapon which, like a projectile e23000, uses two long parallel electrodes to accelerate a “sliding short” armature.

There are 0 items in your cart. The helical railgun is a cross between a railgun and a coilgun.


As briefly discussed above, the stresses involved in firing this sort of device require an extremely heat-resistant material. However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionized, gas-like particles, instead of a solid slug of material. Orbiting skyhooks Skyhook Momentum exchange tether. Retrieved 13 February The weapon was able to produce doughnut-shaped rings of plasma and balls of lightning that exploded with devastating effects when hitting their target.

Alternatively, very long rail systems may be used to reduce the required launch acceleration.

For this product you can select the desired delivery method at the shopping cart: Caonn if conventional defense systems react fast enough, they are expensive and only a limited number of large interceptors can be carried. The launcher had a mm roundbore. Product successfully added to your shopping cart.

These terminals work the same way as in Estonia. This halves the required current through the rails, which reduces the power fourfold.

A 32 megajoule railgun shot is equivalent to about 23, foot-pounds, so a single 32 MJ shot has the same muzzle energy as aboutYou can order the goods to one of the Omniva Parcel terminals.

Wikimedia Commons has media related to Railgun. It can also be noted that the textbook formula for the high frequency inductance per unit length of a pair of parallel round wires, of radius r and axial separation d is:. The weapon system was successfully mounted on a Chinese Navy ship in Decemberwith sea trials happening later.


Railguns are being examined for use as anti-aircraft weapons to intercept air threats, particularly anti-ship cruise missilesin addition to land bombardment. Under high-use conditions, current railguns would require frequent replacement of the rails, or to use a heat-resistant material that would be conductive enough to produce the same effect. He filed for a US patent on 1 Aprilwhich was issued in July as patent no.

Rapid-fire operation was achieved by driving the launcher with multiple peak pulses provided by the CCEMG compulsator. Archived from the original on 3 January Archived from the original on 12 February DuringSir Mark Oliphantan Australian physicist and first director of the Research School of Physical Sciences at the new Australian National Universityinitiated the design and construction of the world’s largest megajoule homopolar generator.

Its development reportedly started in Archived from the original on Such a development would then convey a further military advantage in that the elimination of explosives from any military weapons platform will decrease its vulnerability to enemy fire.

These parameters are well beyond the state of the art in materials science.
