使用电能代替或者辅助化学推进剂发射炮弹的装置。电炮能突破常规炮弹初速低于2000米/秒的界限,因此炮弹速度高,射程远,精度高,动能(破坏力)大。电炮可分为电磁炮和电热炮两大类。电磁炮完全依靠电磁能发射炮弹,又分为导轨炮和线圈炮两种。导轨炮(railgun)的工作原理是:炮弹位于两根平行的铜制导轨中问,当强电流从一根导轨经炮弹底部的电枢流向另一根导轨时,在两根导轨之间形成强磁场,磁场与流经电枢的电流相互作用,产生强大的电磁力(洛仑兹力),推动炮弹从导轨之间发射出去,理论上初速可达6000～8000米/秒。导轨炮的
A device that uses electricity instead of or in addition to a chemical propellant to fire shells. Electric can break the conventional artillery muzzle velocity of less than 2000 m / s, so the projectile speed, long range, high precision, kinetic energy (destructive power). Electric cannon can be divided into two major categories of electromagnetic guns and electric guns. Electromagnetic guns completely rely on the electromagnetic cannon fired shells, and is divided into two kinds of rail guns and coil guns. The railgun works on the principle that the shell is located in two parallel copper rails and when a strong current flows from one rail to the other rail through the armature at the bottom of the shell, The magnetic field, the magnetic field and the current flowing through the armature interact to produce a strong electromagnetic force (Lorentz force), propelled the projectile from the launch between the rails, in theory, the initial velocity of up to 6000 ~ 8000 m / s. Rail gun
