Russian scientists fired the electromagnetic gun-railgun on an aluminum disc. Tests of electromagnetic accelerator of a railgun is held in Shatura branch, joint Institute for high temperatures RAS. During the tests, scientists fired a 15-gram plastic bullet on an aluminum disc. As a result, the target was a crater.
According to the researcher of joint Institute for high temperatures RAS Michael shurupova, the bullet hit the target at a speed of about 3 kilometers per second.
The railguns are devices capable of accelerating objects to extremely high speeds by the force of electricity and magnetic fields. As a rule, a set of several parallel conductors through which current is passed ultrahigh strength. If the rail touches the conductor, the Lorentz force will push out and up to ultrahigh velocities, unavailable for gunpowder weapons.
