Popis: A pulsed electromagnetic accelerator with an external magnetic field can be used as a powerful plasma engine. In the installation of such type, the plasma piston, initiated in the breech section of the rail channel, accelerates under the action of the Ampere force and at the time of exit from the channel muzzle part have a speed of the order of 1-30 km/s depending on the discharge current. In the process of motion along the channel of the plasma piston, the plasma mass effectively increases in it due to material erosion from the surface of the electrodes (rails).The calculated and experimental data on the achieved values of the specific impulse and thrust of such an engine will be given in the report.
