INVENTION: APPARATUS FOR RECOILLESS FIRING OF PROJECTILES FROM A LAUNCHING TUBE ABSTRACT OF THE DISCLOSURE An apparatus for recoilless firing of projectiles from a launching tube comprises within the launching tube a forward brake ring, a forward sabot, a propellant charge with an ignition element or screw, a rear sabot, a counter-mass, and a rear brake ring, arranged within the launching tube in the sequence listed. Upon ignition of the propellant charge, high acceleration forces are created by the ensuing high peak pressures, which consequently requires a robust construction. In order to avoid this drawback, according to the invention the aforementioned disadvantage can be eliminated by using a propellant charge comprising a first cylindrical propellant charge body and a second annular propellant charge body which surrounds this first cylindrical propellant charge body.
