Recoil free firing weapon

The innovation relates to a recoilless firearm, especially a large-caliber weapon with a narrowed one rear gas outlet with nand firearm.

Weapons that are open on both sides to avoid recoil Have pipe are known. In the case of a tube with a uniform cross-section throughout, there is a relatively large amount of powder required to get the desired initial speed of the storey. TJm to get the same initial velocity of the projectile with smaller amounts of powder and while also making the weapon recoil-free, it is known to narrow the rear muzzle of the weapon barrel and for example to be provided with a nozzle.

In the case of weapons of the aforementioned type, it is necessary to keep the powder together for as long as possible when the propellant powder is burned to maintain good ignition and an even pressure increase. For this purpose it is already known that the To dam the propellant charge to the rear or to arrange a rupture disc, which only releases the outlet for the gases at a certain minimum pressure. It is also known to use a perforated cartridge to use which allows the gases to escape, but opposes them with a certain flow resistance.

The task of the innovation is to create a large-caliber weapon, which works without recoil, so that it τοη one or two man operating personnel from the hand or from the shoulder shot can be. The projectile should have a relatively high initial speed for ammunition to be fired without recoil and good accuracy even at greater distances to have.

For this purpose, it is proposed according to the innovation, between the weapon barrel and the rear outlet opening a space with an enlarged cross section compared to the weapon barrel or the outlet opening and to provide a grate in this, the passage cross section of which is equal to or greater ^. than the cross section of the gun barrel. This Eost can be designed as a plan grate and arranged in a rear part of the weapon that can be removed or folded down being. The outlet opening for the powder gases, which is also provided in the rear part of the weapon, can be known per se Way be designed as a nozzle whose narrowest cross-section is equal to or smaller than that of the weapon barrel.

Details of the innovation emerge from the description of an embodiment shown in the drawing.

The Pig. shows a partial longitudinal section of the simplified illustration Weapon with a device after the firing and with a wing-stabilized projectile inserted in it and its propellant charge.

An internally smooth, cylindrical tube 1 expands into one Chamber 2, which has a locking flange ring 3 on the outside. A rear part that can be coupled to the chamber 2 via a flange ring 4 5 of the weapon has a nozzle-shaped constriction 6 and a adjoining, funnel-shaped relaxation space 7 on. In the rear part 5 a plan grate 8 is arranged, the

Passage openings 9 adhere together a cross section of at least is as large as the cross section of the weapon barrel 1 and preferably larger than the cross section of the nozzle 6 at its narrowest point.

In the tube is a wing-stabilized projectile 10, the is incorporated into a propellant charge 11, 12. Like the Pig. shows, the one part 11 of the propellant charge around the stern and a tail unit 13 of the G-eschichtes 10 around, the other part 12 the propellant charge is provided in the chamber 2 between the weapon barrel 1 and the grate 8. The propellant charge parts 11, 12 are packaged in a plastic sleeve 14.

When the propellant charge 11, 12 is ignited, mechanically or can take place via electrical ignition means, a relatively large amount of propellant charge is close together in the chamber 2, which is held back by the grate 8. This results in good ignition conditions and the gas pressure can increase build up evenly. Flow through the through holes 9 Powder gases into the space behind the grate 8 and through the nozzles 6, 7. The nozzle effect creates in the space between the Grate 8 and the nozzle 6 a pressure which is approximately equal to the pressure in front of the grate 8, i. H. is in chamber 2. The floor 1o is after ejected in front without exerting a recoil on weapons 1 to 8.
