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. | ||||||
| 63 | Method and Apparatus for Launch Recoil Abatement | US13739854 | 2013-01-11 | US20140076134A1 | 2014-03-20 | Wayne K. Schroeder |
| Recoil forces of a launched missile and the moment force imposed on the launch platform can be reduced by use of a recoil abatement element in communication with a launch tube. The recoil abatement element includes at least one nozzle configured to receive therethrough exhaust gasses from a missile when launched. The nozzle can be canted or otherwise configured to direct the exhaust gasses in a desired direction to thereby offset moment force imposed on the platform by the exhaust gasses. | ||||||

| 67 | Method and apparatus for muzzle lift compensation | US12461196 | 2009-08-04 | US20100037760A1 | 2010-02-18 | Brian Stock |
| A method and apparatus counteracts the muzzle lift of a firearm resulting from recoil, and a firearm has an integral counteracting structure. A port extends from an inner surface of the firearm barrel bore to an outer surface of the barrel, forward of the location that the propellant ignites, to an occluding structure located beneath the grip surface of the firearm. When the propellant is ignited, and the projectile passes the relief port, a portion of the propellant gas exits the bore prior to the muzzle end, travels through the propellant gas relief tube, and exerts a force on the occluding structure. The force acts downward on the firearm, counteracting the recoil-induced muzzle lift. | ||||||

| 75 | Arrangement for braking a sabot | US749003 | 1985-06-25 | US4753152A | 1988-06-28 | Theodor Baechler |
| To brake a sabot accelerated in a launcher of a recoiless rifle tube a mandrel shaped braking sleeve is disposed in the tube and an intermediate space is provided between a tapered surface of the mandrel and the tube into which the material of the front edge of the sabot expanded. In this way when the sabot is accelerated against the mandrel, its front edge slides along the tapered surface, radially outwardly into the intermediate space. This functions to deform and positively stop the movement of the sabot before it leaves the tube. | ||||||
| 76 | Recoil reducer | US385520 | 1982-06-07 | US4404887A | 1983-09-20 | Edward T. Piesik |
| A missile launcher tube from which a missile is fired from a forward end causing gases to exit out the aft, or exhaust gas, end of a launcher tube in which the aft end is provided with a conical surface (flare) forming a nozzle so that as the missile exits from the forward end, a forward pressure force created by the exhaust gas acting on the conical surface as the exhaust gas exits from the aft end opposes and reduces an aft end directed recoil force. The conical nozzle is located entirely within the outer surface of the launcher tube so that the launcher tube envelope is not disturbed. | ||||||
| 77 | Apparatus for braking a free piston, which is driven at high acceleration within a tube | US848195 | 1977-11-03 | US4148244A | 1979-04-10 | Werner Schnabele; Paul VON Malottki |
| An apparatus for braking a free piston which is driven at a high acceleran within a tube and, particularly, in a recoilless firearm, comprises a tube which has a first portion of a first diameter and a second portion of a second diameter greater than the first portion with a transition portion therebetween. A free piston is freely movable in the first portion and it has substantially the same diameter as the first portion. A braking sleeve is secured to the interior wall of the tube in the second portion thereof and it has an edge facing the piston which is beveled inwardly to a knife edge. A deformation ring is carried in the second portion between the braking sleeve and the piston and the piston carries an expanding member which moves outwardly when the piston is moved from the first portion through the transition portion to the second portion to contact the deformation ring and to force it against the edge of the braking sleeve so as to deform the braking sleeve starting from its edge which faces the piston radially inwardly to effect the braking of the piston. In one embodiment, the expanding member comprises a ring carried on the piston which rides in a groove of the piston and which is urged outwardly by gases which propel the piston and which communicate with the groove to a passage defined in the rear face of the piston. In another embodiment, the expanding member includes a ring carried on the opposite end of the piston from the end exposed to the propelling gases with a sleeve having a plurality of longitudinal slits which permit the sleeve to be deflected downwardly by the first portion of the tube in which the piston is movable, but which may move outwardly when the piston moves through the transition zone to the second portion so as to contact a deformation ring which is urged by the expanding member to deform the braking sleeve. | ||||||

| 79 | Assembly for launching a projectile | US700743 | 1976-06-29 | US4073213A | 1978-02-14 | Emile J. Stauff |
| An assembly for launching a projectile comprises a launching tube having a smooth or rifled bore, a charge of gunpowder located in the tube for firing a projectile which is loaded in the tube in front of the charge, and a body of braking propellent which is located in the tube behind the gunpowder charge and which consists almost entirely of combustible substances. The body of braking propellent may be connected to the projectile by means of a cylindrical sleeve to form a rigid unit which is loadable as a round in the launching tube, the sleeve containing the gunpowder charge. | ||||||
| 80 | Aircraft having recoilless rifle | US30245172 | 1972-10-31 | US3827332A | 1974-08-06 | LINDSAY D |
