What is a railway weapon?

Railway gun, or simpler, Railgun , uses the magnetic field driven by electricity to speed up the projectile. Although the basic ideas that are the basis of the construction of a railway gun are simple, the burning of a typical projectile of the railway weapon results in a huge repulsive power. The result is that The railway weapon must be operated after almost every shot, so it is less practical than conventional projectiles. They also require a very large power supply that are able to provide a million current of current, making it difficult to create portable railway weapons. There is a projectile capable of performing electricity between the rails and finishing the circuit. When metal rails are electrically charged, they behave like electromagnets and create a magnetic field that circulates around each rail. One field moves clockwise around the rail, the other clockwise and creates a magnetic field between creating a pure force parallel to the rails, far away from the power supply. The projectile behaves like any charged wire in the electric field and experiences strength perpendicular to the direction of the current and the direction of the magnetic field. This is called Lorentz's power.

6 The broken circuit ends the flow of electricity. The projectile must establish physical contact with rails during acceleration. If the projectile moves fast enough, friction itself can seriously damage or even drop rails and lack sufficiently thick materials. Also, if the rails are not securely attached to a stable surface, they can be driven by strong energies inside the rail.

Many millions of dollars have been introduced into the Railway Weapons Research by the United States Army, and many successful prototypes have developed, which have very high speed speeds, 3.5 km/s (2.17 MPS), about 3 times faster than modern rifles. However, these suggestions require large power supply and maintenance remainingA problem. The US Navy expressed interest in railway weapons because of their unspeakable ammunition, but it was not common. One proposed solution to the problem of wear of a railway gun is the idea of ​​using very small projectiles accelerated at very high speeds, which is sometimes known as Needlegun .

Railway weapons were also discussed in connection with peace applications such as space travel. A very long railway gun could be used to speed up the useful load, or a mass control One of the disadvantage is the high initial investmentent must be built by such a bulk driver. Creating a bulk driver that accelerates the projectile to leak speed acceptable to human passengers (~ 2 GS) would require a length of length ~ 50 km (30 million). Further potential application of railway weapons may be in the nuclear fusion arena, where huge pressures and temperatures are required to join the atomic core.
