Are railguns efficient?

About 70% to 75% efficient. Tank mounted railguns would be more efficient then ship mounted. Also hyper fast railguns would be less efficient then typical artillery speeds. The faster it goes the more friction from rails and air resistance.

How much energy does the railgun use?

A railgun system needs 25 megawatts of energy flowing through it, and according to Captain Michael Ziv, the Navy's program manager for rail guns and energy weapons. Most currently serving destroyers don't have more than nine megawatts of electricity that they can shift around.Apr 8, 2014

Are railguns more powerful than guns?

A railgun has a higher velocity, and could potentially have a higher rate of fire than coilguns,is less tecnologically complex, and can even be used as a mele weapon if you run out of ammo(shove the muzzle in their face and pull the trigger and you not only smack them with a sliding armature traveling at mach speed but ...

Is a rail gun more powerful?

This means that while a normal gun might manage a projectile speed of around 2km/s, a railgun could blast out projectiles 50 per cent faster, at at least 3km/s. ...Jan 4, 2019

How much armor can a railgun penetrate?

Using electromagnetic energy, the gun can fire a shell weighing 10kg at up to 5,400mph over 100 miles – with such force and accuracy it penetrates three concrete walls or six half-inch thick steel plates.Feb 5, 2015

How much damage can a railgun do?

The Rail Gun deals 500-550 damage to structures and can also pierce through a single structure without losing damage.


What can a railgun destroy?

Unlike present-day artillery shells, railgun projectiles are just that – projectiles. They contain no explosives. Just the kinetic energy imparted by the projectile, travelling seven or so times the speed of sound, can rip through steel or concrete, destroying anything in its path.Jan 23, 2020


How far can Railguns shoot?

Railguns use magnetic fields created by high electrical currents to accelerate a projectile to Mach 6, or 5,400 miles an hour. The velocity is sufficient to give the EMRG an effective range of 110 nautical miles, or 126 miles on land.May 12, 2020


Why do Railguns destroy themselves?

This is because the electric current actually flows through the projectile from one rail to the other rail[1]. This produces huge amounts of wear on the barrel, making it extremely difficult to maintain the barrel.


Why are coilguns so inefficient?

Why do I think coilguns are so inefficient? Because they inherently have a long "air gap" down the middle of the firing tube. It builds in a relatively huge amount of magnetic reluctance in the magnetic circuit.Jun 3, 2008


Are coilguns more efficient than Railguns?

The advantages of rail guns is that they are much simpler to build and operate than a coil gun. They are also more powerful as they have a direct contact between the projectile and the rails while the coil gun has a gap between them.


Is a coilgun better than a railgun?

A coilgun on the otherhand is the best option because it can be soaked in polymer and fired underwater whereas a railgun can't cause it needs direct current going through the rails, it has less recoil, lower rate of fire, higher efficiency, but lower velocity…


How fast is the projectile from a rail gun?

Railguns are being researched as weapons with projectiles that do not contain explosives or propellants, but are given extremely high velocities: 2,500 m/s (8,200 ft/s) (approximately Mach 7 at sea level) or more.


Do coilguns recoil?

Therefore, for a coilgun of equivalent power to a railgun, the coilgun's recoil will hurt more since it is at some points low and at others high… And uneven recoil hurts a lot more than steady smooth force.


How powerful is the Navy railgun?

A high-velocity projectile leaves the gun at speeds up to seven times the speed of sound. The kinetic energy is theoretically enough to inflict serious damage on a surface ship without the explosives.Jul 1, 2021


How efficient is a railgun motor?

  • They are on par with a typical brushed DC motor. About 70% to 75% efficient. Tank mounted railguns would be more efficient then ship mounted. Also hyper fast railguns would be less efficient then typical artillery speeds. The faster it goes the more friction from rails and air resistance.


What are the advantages of railguns over cannons?

  • Current railgun technologies necessitate a long and heavy barrel, but a railgun's ballistics far outperform conventional cannons of equal barrel lengths. Railguns can also deliver area of effect damage by detonating a bursting charge in the projectile which unleashes a swarm of smaller projectiles over a large area.


How is the driving force of a railgun determined?

  • For a more workable simple model, a useful alternative is to use a lumped circuit model, to describe the relationship between the driving current and the railgun force. In these models the railgun is modeled on an electrical circuit and the driving force can be determined from the energy flow in the circuit.


Why do some hypervelocity research projects use railguns?

  • In some hypervelocity research projects, projectiles are 'pre-injected' into railguns, to avoid the need for a standing start, and both two-stage light-gas guns and conventional powder guns have been used for this role.
