  • Patent number: 8707846
    Abstract: The invention relates to a weapon (1), constructed relatively simply and compactly, for shooting ammunition (2), with a barrel (3) with recoil and a braking device (12) damping the barrel recoil. According to the invention, a plastically deformable absorption body (12) is used as the braking device (12) for reducing the recoil energy. Thus, a weapon assembly for firing ammunition is provided, wherein the weapon assembly includes: (a) a weapon including a weapon barrel provided with a recoil spring that holds the weapon barrel in an initial position; and (b) a braking device that damps barrel recoil of the weapon barrel when firing ammunition, wherein the braking device is a plastically deformable absorption body.

  • Patent number: 7886649
    Abstract: 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.

  • Patent number: 7841267
    Abstract: An arrangement for recoilless launch including a non-gaseous reaction mass having a weight in a range of about 25% to about 75% of a weight of a projectile. For the same projectile energy, less propellant is required than a rocket, which minimizes backblast and reduces before-launch weight. The recoilless launching is adapted to shoulder-launched projectiles in a confined space. The reaction mass may be particles associated with a propellant so as to be released concurrently as the propellant turns into gas and accelerated by and with the propellant gas in a nozzle.

  • Patent number: 7418896
    Abstract: A recoilless weapon system is provided rear portion, a barrel in movable connection to the rear portion, and a handle portion in removable connection with the barrel and/or rear portion. Further, a ballast payload cartridge is removably disposed within a ballast payload cartridge portion of said rear portion, and serves as a center breach to support a combat cartridge. The ballast payload cartridge may have a side primer disposed therein, which allows a single weapon firing pin to simultaneously initiate both the combat cartridge primer and the ballast payload cartridge primer.

  • Patent number: 6971299
    Abstract: 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 (12, 26, 26?, 38) acting against the low-pressure system. The high-pressure system (7, 23, 23?, 36) shall, in practice, be formed by the combustion chamber for the weapon propellant charges (8, 22, 22?, 35) while the main part of the low-pressure system (25, 25?) 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 (1, 13).

  • Patent number: 6446535
    Abstract: A recoilless projectile launcher system has a projectile residing in a launch tube with a propellant charge coupled to the aft end of the projectile. A first tube is slidingly fitted in the launch tube, is coupled to the aft end of the projectile, and encases the propellant charge. The first tube has a first portion extending from the propellant charge and a second portion extending from the first portion towards the breech end. The first portion has a constant inside diameter while the second portion has a reduced inside diameter relative to the constant inside diameter of the first portion. A piston, slidingly fitted in the first portion of the first tube, is positioned adjacent the propellant charge. A second tube is coupled to the piston and extends towards the launch tube's breech end. The second tube has a constant inside diameter and a constant outside diameter with the constant outside diameter forming a sliding fit with the second portion of the first tube.
