Traveling charge

Schematic of traveling charge propulsion concept

Traveling charge is an additional explosive charge attached to the bottom of the projectile so that it travels with the projectile inside the gun barrel while burning. The concept was proposed by H. Langweiler in 1939. ^{[1] [2] [3]}
