ABOUT COIL GUN

  • It is a type of electromagnetically powered weapon capable of launching projectiles with very high speed and accuracy.
  • These are also known as magnetic accelerators or Gauss guns.
  • Working-
    • Coil guns feature a series of coils arranged along the barrel of the gun, each one constituting a stage.
    • Each coil is energised one after another to create a magnetic field that can levitate and propel a projectile forward.
    • The projectile typically stays suspended in the centre of the coil during launch.
  • Repeated firings do not cause wear on components.
  • Advantages – higher launch speeds, lower launch costs, and shorter preparation time, compared to traditional artillery.
  • Applications in areas such as weapon systems, near-earth satellites and high-speed missile launches.
