A modular weapon system of a preloaded recoilless gun including a barrel provided with a shell, a propellant charge and a countermass. The weapon system is configured in two parts including a first part of the barrel and a second part of the barrel. The first part of the barrel includes the shell and the second part of the barrel includes the propellant charge and countermass. A releasable locking device interconnects the second part of the barrel with the first part of the barrel.

Weapon system

A method of configuring a preloaded anti-armour weapon of the disposable type and including a countermass container in transport mode for restraining a shell loaded in a barrel of the weapon. The countermass container is replaced with a locking ring and the loaded barrel is placed in a first compartment and the countermass container is placed in a second compartment of a transport box.

Method of configuring weapon

An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container that can be opened at both ends. The invention aims to bring about a symmetrical opening with favorable recoil in a better way than in previous constructions. This is achieved by the countermass including elements that can bind and retain the liquid symmetrically in a desired geometry over the cross section of the barrel and the cross section of any following expansion part.

Arrangement for weapon

The subject invention concerns a method and a device enabling said packed countermass material () to open up said countermass packagings () in relation to the firing of countermass weaponry. The basic concept for the subject invention is, thus, that one near the rear outlet end () of a countermass weapon () barrel fashion a number of blades () to the interior of the outlet that protrude inwardly into the barrel sufficiently so as to cut into said countermass container (), which is pressed past said blades () upon firing said weapon ().

Countermass weaponry

An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container with an openable cover provided with break indications. The arrangement brings about a symmetrical opening operation with favorable recoil in a better way than in previous constructions. This is achieved by the introduction of a guiding folding support arranged adjacent to the openable cover on the inside of the cover relative to the countermass container.

The subject invention concerns a general method of producing countermass weaponry and is based on the use of a high-pressure system and a low-pressure system with a countermass () acting against the low-pressure system. The high-pressure system () shall, in practice, be formed by the combustion chamber for the weapon propellant charges () while the main part of the low-pressure system () shall, in initial stages, be formed by the storage and acceleration chamber for the countermass. The advantage of the subject invention is that said invention offers a possibility of achieving lower pressure levels around the grunner without, for such an end, diminishing the range of the weapon ().
