| 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. | ||||||

| 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 | ||||||

| 50 | Recoilless launching | US12587326 | 2009-09-22 | US07841267B1 | 2010-11-30 | Matthew J. Sanford |
| 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. | ||||||

| The present invention relates to a method and a device by means of which it has been made possible, without gas discharge to the surrounding environment, to accelerate the speed of a powder-gas-driven projectile from zero to a speed which gives the projectile free-flying characteristics. According to the invention, this has been made possible by utilizing at least some of the expansion force from the propellant powder charge, which discharges gas when it is initiated, for, by a displaceable piston, driving a countermass out of the rear part of the projectile in the direction opposite to the desired flying direction of the projectile. | ||||||

| A countermass for use in a weapon to balance the forces arising when a launchable unit is launched from a launcher tube of the weapon. The countermass includes a first container enclosing a liquid. A countermass weapon includes a launcher tube open or openable in both ends. The launcher tube houses a launchable unit, a countermass including a first container enclosing a liquid, a pressure chamber, and 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. The first container is made of a non-rigid material. A second container is provided to cover or almost cover the first container. The second container is designed with damping characteristics. | ||||||

| 57 | Triple-tube, dispersible countermass recoilless projectile launcher system | US09784105 | 2001-02-16 | US06446535B1 | 2002-09-10 | Matthew J. Sanford; Gregory D. DuChane |
| 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. A dispersible countermass resides in the second tube and is dimensionally stable independent of the second tube. | ||||||
| 58 | Liquid disrupter with reduced recoil | US09700412 | 2000-11-15 | US06408731B1 | 2002-06-25 | Josef Elsener |
| The disrupter (16) includes an elongated hollow barrel (18) having a cylindrical inner chamber (20), a closed rear (26) end and an opened front end (22), the latter closed with a front frangible seal (38). A channel member (46) partly surrounds an intermediate portion of the barrel, and is securely attached thereto. A pair of recoil channels (76, 78) extend from the barrel inner chamber, radially outwardly and rearwardly through the barrel and the channel member, and are linked to rearwardly oriented recoil tubes (52, 54) which have opened rear end portions (60, 62) closed with rear frangible seals (64, 66). In use, a cartridge (90) including an explosive charge (88) is to be inserted in the barrel inner chamber at its rear end, and the barrel, recoil channels and recoil tubes (52, 54) are to be filled with water. The frangible seals (38, 64, 66) prevent the water from leaking out of the disrupter while it is positioned near a bomb to be deactivated. A trigger (36) is linked to the disrupter, and more particularly to the cartridge, to remotely detonate the explosive charge. Upon the explosive charge being detonated, a portion of the water is propelled and ejected at high velocity out through the barrel front end, rupturing the front frangible seal, to puncture the bomb outer shell and deactivate the bomb inner detonating components. Another portion of the water is redirected through the side recoil channels and recoil tubes, rupturing the rear frangible seals, to be ejected rearwardly out of the disrupter. The recoil created by the detonation of the explosive charge which ejects the water through the barrel front end, is at least partially counteracted by the water being laterally and rearwardly redirected to be ejected rearwardly out through the recoil tubes. The recoil tubes have at their rear ends (60, 62) transverse blades (73, 74) for wide angle dispersal of the fluid jet being ejected rearwardly. | ||||||

| A projectile (3) to be launched by a marksman toward a target using a launch device, the projectile comprising a shaped-charge warhead (14) whose axis (38) coincides with that of the projectile, initiation of which is caused by an igniter (17). The projectile is characterized by a shaped charge which generates a core, and igniter (17) initiates the shaped charge along the trajectory and at a given distance from the launch device so that the marksman is protected from projectile explosions. | ||||||
| 60 | Double piston propulsion unit | US39143 | 1993-04-23 | US5313870A | 1994-05-24 | Robert O. Clark |
| A double piston propulsion unit for a recoilless mass/countermass projectile launcher comprises two hollow cylindrical pistons (22, 23) arranged in a back-to-back relationship with closed outer ends and open inner ends, the open inner ends being joined together by a circumferential rupturable connecting means so that the pistons form a vessel in which a propellant charge (34) is enclosed. In operation, the unit is slideably located inside the open-ende launch tube (1) of the projectile launcher at its mid-point. The propellant when initiated causes a build up of propellant gases inside the vessel and when the gas pressure reaches a pre-determined value the connecting means fails in tension and the piston (22, 23) are propelled in opposite directions. The tensile and compressive force experienced by the pistons (22, 23) during the firing of the unit are substantially decreased compared to known units, so that relatively lightweight pistons (22, 23) can be employed. | ||||||
