6971299	Countermass weapon 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 syst...	12/06/2005
5952601	Recoilless and gas-free projectile propulsion A recoilless and gas-free projectile propulsion device is provided. A hol pressure vessel is sealed on a first end to an aft end of a projectile in a launch tube. The pressure vessel is further open on a second end. A propellant charge-filled pressure ch...	09/14/1999
5900575	Bottom plate member The invention relates to a bottom plate member (6) which is designed and made for initially tightening a chamber in which a high gas pressure is generated, for example the propellant charge chamber (4) in an ammuniton round for a recoilless weapon system ...	05/04/1999
5337648	Countermass for recoilless weapons A countermass for a recoilless weapon which is intended to be placed behind the propellant charge of the weapon projectile and intended to depart together with the propellant gases that exit from the rearward end of the weapon when the projectile is proje...	08/16/1994
5322002	Tube launched weapon system A tube launched rocket system which uses a plurality of small propellant charges located within the tube to propel the rocket. The charges form part of the outer wall of a traveling propulsion chamber. The rest of the chamber is substantially defined by a...	06/21/1994
5285713	Countermass for recoilless weapons A countermass for recoilless weapons which is intended to be placed behind the projectile propelling charge (3) of the weapon and which is also intended to depart together with the propellant gases exiting rearwardly from the weapon when the projectile is...	02/15/1994
5109750	Closed-breech missile and weapon system A lightweight reusable closed breech weapon system 116, for infantry in antiarmor or antipersonnel applications wherein offensive or defensive postures are required. The weapon system 116 comprises a two stage missile 92 adapted to be fired from a preload...	05/05/1992
4962689	Gas generator missile launch system A missile launching system with an open-ended cylindrical container (10) having a bore in which a slidable piston (20) is located between the missile (12) and a gas generator (14) adjacent the container aft end (16). The piston (20) area is substantially ...	10/16/1990
4676136	Apparatus for recoilless firing of projectiles from a lauching tube 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, ...	06/30/1987
4574680	Arrangement in recoilless weapons An arrangement for firing a projectile from a recoilless weapon with a firing barrel open at both of its ends, by means of a propellant charge tamped toward the rear with an inert, pulverulent compensating mass, reduces the noise and the shock waves of th...	03/11/1986
4132149	Liquid propellant weapon system A gun and ammunition system utilizing a round of ammunition which contains a supply of liquid propellant and after ignition pumps this propellant into the combustion chamber of the gun....	01/02/1979
4132148	Expellable reaction mass for recoilless projectile launchers A reaction mass for a launching tube having a centrally positioned propellant charge for propelling a missile at its forward end and a reaction mass located rearwardly of the propellant charge which is propelled at the rear end, comprises an inert, readil...	01/02/1979
4126077	Recoil reducing system for rifles, guns, cannons and the like A system designed to reduce the recoil of any ball and powder type weapon such as guns, rifles, cannons or the like is disclosed. In a ball and powder type weapon the bullet or shell is propelled out of the barrel by the high pressure created by the explo...	11/21/1978
4091709	Recoilless rifle nozzle A plate having a plurality of small openings therein mounted to the exit t of a recoilless weapon for reducing the depth of penetration of the disturbed gas field without significantly effecting the recoil reduction characteristics of the weapon....	05/30/1978
4073213	Assembly for launching a projectile 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 ...	02/14/1978
