How fast can a coil gun shoot?
The coil gun was predicted to shoot at 22.7m/s. The actual velocity of this particular shot was 21.25m/s. Launch position and slight variations in capacitor bank voltage can have a larger effect than this on velocities.
How does a coil gun work?
Coil guns use a strong magnetic field to accelerate ferromagnetic projectiles. The projectile is situated at one end of the coil and is pulled to its center by magnetic induction. When the current is switched off, the projectile travels forward down the barrel, exits the gun and moves towards the intended target.
What is the most powerful coil gun?
ANVIL rifle
The ANVIL rifle is the most powerful handheld Gauss rifle ever offered to the public. However, since we are in the infancy of the technology, that means a 20-pound rifle (20 pounds without battery, that is) fires its 12mm steel projectile at a muzzle velocity of about 275 fps, producing 65 foot-pounds of energy.
How much power does a coil gun need?
You need 25v at 10A, but only for about 100 msec (se al value) while coils are energized. So, that’s 250W times 0.1 seconds, or 25 W-seconds total. If you want to be able to fire once every 5 seconds, you need a supply capable of generating a continuous power of 5W at 25v.
How much power does a coil gun use?
A 1992 NASA study calculated that a 330-ton lunar superconducting quenchgun could launch 4400 projectiles annually, each 1.5 tons and mostly liquid oxygen payload, using a relatively small amount of power, 350 kW average.
How powerful is a coilgun?
Your projectile will leave the barrel with a hefty 4.5∗1011 joules of kinetic energy. If your coilgun only wastes 1% of that energy in heating the projectile, 4.5 gigajoules of energy will be absorbed by it (a little over the energy released by the detonation of a tonne of TNT, as it happens).
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.
How are coil guns used in the military?
Recently, a coil gun was brought to the attention of engineering community as electromagnetic alternative to the chemical launchers. Various studies were performed on coil gun systems focused on achieving the high muzzle velocity in military applications and for satellite launching.
How are coil guns designed to improve muzzle velocity?
The coil gun is optimally designed using an evolutionary algorithm (EA) as optimization technique. In order to verify the improvement of muzzle velocity by optimal design, the prototypes of coil gun system are manufactured and the experiments to launch the projectile are performed.
How does a multi stage coil gun system work?
A multi-stage system is a way to raise the effectiveness of the coil gun. It accelerates the projectile by controlling the relations between each stage of the solenoid and projectile.
How does a coil gun propel a projectile?
An electromagnetic launcher (EML) is a device used to propel and accelerate a projectile by converting electrical energy into kinetic energy. A coil gun, which is a type of EML, can propel a projectile without any mechanical friction so that there is no theoretical limit to the velocity.
