Electromagnetic thrust transmitting device

The invention relates to an electromagnetic thrust transmitting device. The electromagnetic thrust transmitting device comprises a first track, a second track, an armature, a projectile, a high-powerpulsed power source and a switch. The first track and the second track are parallel and insulated mutually and made from metal; the armature is located between the first track and the second track, can slide along the first track and the second track, and is in sliding electric contact with the first track and the second track; the projectile is pushed by the armature; the first track, the secondtrack, the armature, the switch and the power source constitute a series loop, when the switch is closed, the power source supplies power to the loop, a magnetic field is generated in the loop throughcurrent of the first track and the second track, then the current flowing past the armature forms electromagnetic force under the effect of the magnetic field, and the electromagnetic force increasesthe speed of the armature a
