Gun barrel for acceleration of projectiles - has pairs of electrodes spaced along length connected to electrical source for preventing gas pressure redn.

摘要

The pairs of electrodes (5a,5b to 8a;102-104) are connected to the energy source (18,113) directly or across a switching system. The voltage of the energy is selected so that it respectively forms an electric arc to heat the gases in the barrel (1,100), when the rear part of the projectile (19,111) passes the respective electrodes. The location (X1) of the first pair of electrodes (8a,8b) is selected so that the heating by the arc (23) begins just when the burning of the charge has ended. The pairs of electrodes are arranged co-axially one behind the other at the inner wall of the barrel. ADVANTAGE - Developed so that decline of gas pressure in barrel is prevented in simple manner.
