Abstract

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.

IPC Classes  ?

• F41A 1/08 - Recoilless guns, i.e. guns having propulsion means producing no recoil
• F41A 1/10 - Recoilless guns, i.e. guns having propulsion means producing no recoil a counter projectile being used to balance recoil
• F41A 1/00 - Missile propulsion characterised by the use of explosive or combustible propellant charges
• F41A 13/00 - Cooling or heating systemsBlowing-through of gun barrelsVentilating systems

Abstract

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.

Abstract

The invention provides a method and a system for defeating a target containing a flammable or explosive fill and an incendiary penetrating projectile for use in the method and the system. The incendiary penetrating projectile contains a non-detonating incendiary composition that is ignited prior to penetrating a target.

• F41H 11/14 - Explosive line charges, e.g. snakes

Abstract

The invention provides a short-range, self-propelled, non-fragmenting breaching device to breach a wide variety of doors and barricades with high efficiency, high gunner safety and low collateral damage. The invention also provides a method of preparing the breaching device and a method of breaching a target using the breaching device.
