Abrégé

The invention relates to a countermass propulsion system for shoulder-launched munitions, recoilless rifles, rockets and similar class weapon systems, fired from an enclosure and utilizing a Davis Gun propulsion system by accelerating a projectile in one direction and a countermass in the opposing direction to minimize recoil, light signature and acoustic signature of the weapon system.

Classes IPC  ?

• F41A 1/10 - Canons sans recul, c. à d. armes à feu munies d'un système de propulsion qui ne produit pas de recul utilisant un projectile antagoniste pour équilibrer le recul

Abrégé

A countermass liquid for a shoulder launched propulsion system that has low corrosivity, high density, low viscosity, and a constant viscosity as a function of temperature. Upon function of the shoulder launched propulsion system, the countermass liquid may be expelled through the breach end of the shoulder launched propulsion system by expanding propellant gas. The countermass liquid may be an organic salt selected from the group consisting of at least one or more of cesium formate and potassium formate.

Classes IPC  ?

• C07C 51/02 - Préparation d'acides carboxyliques, de leurs sels, halogénures ou anhydrides à partir de sels d'acides carboxyliques
• F41A 1/10 - Canons sans recul, c. à d. armes à feu munies d'un système de propulsion qui ne produit pas de recul utilisant un projectile antagoniste pour équilibrer le recul

Abrégé

The invention relates to a countennass propulsion system for shoulder-launched munitions, recoilless rifles, rockets and similar class weapon systems, fired from an enclosure and utilizing a Davis Gun propulsion system by accelerating a projectile in one direction and a countermass in the opposing direction to minimize recoil, light signature and acoustic signature of the weapon system. The provided countermass propulsion system comprises: a pressure vessel having a muzzle end and a breach end, wherein the vessel contains a projectile disposed at the muzzle end and a countennass disposed at the breach end; a propellant charge, disposed between the projectile and the countermass; a rupture disk disposed behind an igniter assembly and at a forward end of the countermass; and a projectile retention means that is connected to the projectile and the rupture disk, wherein said projectile retention means comprises a breakbolt.
