![]() ![]() Most conventional firearms operate by the action of expanding gasses forcing a projectile out of a barrel at high speed. Powerful switches alternate the electromagnetic poles in the drive coils as the projectile passes through the coils. We can have a higher max projectile velocity. Coil gun requires high voltage, high amperage, and high speed electrical switches. Hence it can be called as fireless gun or a silent machine gun. Coil gun use electromagnetism to propel the projectile rather than using an explosive charge. Similar principle is used in various areas such as linear motors, Maglev Trains, Roller coasters, etc. It appeared in many contemporary science publications, but never piqued the interest of any armed forces. It was powered by a large electrical motor and generator. This current is repelled by the magnetic field, making the ring jump from the core at a distance of a few meters. The field magnetizes the iron, which induces a circumferential alternating current in the ring. When it is fired, an alternating current flows through the coil creating an alternating magnetic field. The coils are switched on and off in a precisely timed sequence, causing the projectile to be accelerated quickly along the barrel via magnetic forces. It consists of coils arranged along a barrel, so the path of the accelerating projectile lies along the central axis of the coils. This is suitable for military purpose and has a future in next generation advance weaponry.Ĭoil guns are electromagnetic guns that use the Lorentz force () to accelerate a projectile with a conducting projectile. Research has been undergone to increase the speed and its constructional features. The development of coil gun having projectiles ranging from 10 g to 5 kg and speeds up to 1 km/s. ![]() The name GAUSS is in reference to Carl Friedrich Gauss, who formulated mathematical description of the magnetic effect used by magnetic accelerators. It is not a rifle as the barrel is not rifled. In almost all coil gun configurations, the coils and the gun barrel are arranged on a common axis. With this in mind, this paper humbly presents the crown jewel of the electronic weaponry, which brings a great revolution in the field of advanced weaponry systems in our country and makes us proud.Ī coil gun or Gauss rifle is a type of projectile accelerator consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity. Theres been speculation that, this paper has involved in this research. A hybrid power electronic system has been used for firing of a projectile without any chemical substances, without any loud noise and without fire. Each coil is sequentially fired as the projectile moves down the bore. This study is based on electromagnetic gun technology which is constrained to a coaxial geometry to take advantage of the efficiency of closely coupled coils. This paper presents results of a study to estimate the required parameters.
