Abstract: A recoil controller is disclosed whose body 1 incorporates a strategically designed inner surface or surfaces 2. A moving countermass 6 impacts one or more times against one or more inner surfaces 2. During this process momentum is transferred from the countermass 6, to the inner surfaces 2, and then to the body 1 of the recoil controller, and then to anything to which it is attached or against which it is braced. The distributions, over time, of the momenta resulting from this transfer of momentum will depend on various factors including the composition, geometry and placement of the inner surfaces 2. A given recoil controller is designed such that the distributions, over time, of the momenta resulting from its use, are preferable to the distributions, over time, of the original momenta. The countermass 6′ shown in FIG. 1 is the countermass 6 shown after one impact.

Abstract: The invention relates to firearms and especially shotguns as well as devices or mechanisms for reducing felt recoil. In particular, the invention relates to a gas-operated device to reduce felt recoil using a recoil suppressing mass, or recoil mass, to create a counter-acting force to the recoil force. The recoil mass moves in response to the gas pressure in the barrel after firing, and more particularly the control of the flow of gas into a chamber to force the recoil mass to move and generate a recoil suppressing force. In one aspect, incorporating the gas-operated device in a firearm can improve the operator's control of the firearm and measurably reduces felt recoil and/or muzzle climb

Abstract: An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a container, which is mountable in the barrel of the weapon behind an ammunition part. The container is provided with an openable bottom with break indications. A guiding folding support, configured as an annular element, is arranged adjacent to the openable bottom on the outside of the bottom relative to the countermass container. The annular element is provided with a support member for each openable flap forming part of the bottom. Thereby, the opening area in the bottom of the counter mass container is defined by folding edges, formed in each base region of the flaps in the open state as in contact with its corresponding support member.

Abstract: A countermass weapon including a launching tube open or openable in both ends. The launching tube houses a launchable unit, a countermass, a pressure chamber, a propellant charge that upon firing and combustion of the charge in cooperation with the pressure chamber and the countermass accelerates the launchable unit forwards in the tube at the same time as the countermass accelerates backwards in the tube, and a firing and supporting unit connected to the outside of the launching tube. The countermass is designed such that a forward directed recoil is obtained and the launching tube is designed to be disengageable from the firing and supporting unit during the forward directed recoil.

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.

Abstract: 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.

Abstract: 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.

Abstract: There is disclose a round of ammunition for a recoilless weapon of the type having a launch tube which is open at both ends, comprising a projectile, a propulsive charge positioned behind the projectile, a countermass positioned behind the propulsive charge, and a linking means connecting the countermass to the projectile. The linking means is formed of a plurality of small rigid linking rods of low mass and high ballistic coefficient fixed to the peripheral region of the countermass and on retaining elements located on the rear end of the projectile. The retaining elements are designed to shear during the launching of the projectile when the tensile load exerted on the retaining elements by the linking rods exceeds a predetermined level.
