Traveling charge

 ( Explosives ) 

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. Albert W. Horst, A Brief Journey Through the History of Gun Propulsion, Army Research Laboratory report ARL-TR-3671 (unclassified), November 2005 May, I.; et al.
