Abstract: An arrangement for the accelerating of a projectile through the intermediary of a plasma, wherein the plasma is generated by means of an electrical discharging circuit within a metallic tube which has the bottom thereof closed. The one pole of the discharging circuit contacts a first electrode which is formed on the tube rearwardly of the projectile, and in the other pole of the discharging circuit is connected with the casing or jacket of the tube. The projectile, which constitutes the second electrode, forms a current collector which contacts in the casing or jacket of the tube and slides therein during the acceleration of the projectile. The current collector hereby acts in the manner of a sliding contact which, during the acceleration of the projectile, remains in electrical contact with the tube.

Abstract: A barreled weapon with chemical-electrical hybrid propulsion through the intermediary of regenerative injection of fluid propellants through at least one axially movable piston. The propellant components and/or the gases which are developed due to the reaction of the propellant components, are forcibly conducted past an electrode arrangement of a plasma burner in such a manner whereby the electrical energy of a light corona or arc discharge is coupled into the matter streaming therepast.
