Definitions
- the invention relates to a low-recoil machine gun with ammunition according to the preamble of claim 1.
- the object of the invention is a low recoil machine gun with ammunition propose that the propellant powder burns completely in the gun barrel.
- the invention solves this problem according to the characterizing features of claim 1.
- Introduced ammunition components can advantageously be used with the invention will. This is particularly advantageous for small production quantities.
- a recoil-resistant machine gun 1 has a weapon housing 2, a drawn one Gun barrel 3 and a breech, not shown.
- a cartridge chamber 10 In a cartridge chamber 10 is a storey 11 and propellant charge sleeve 12th existing ammunition 13.
- the floor 11 has a floor 15.
- the projectile 11 is partly in the propellant charge sleeve 12.
- the connection between the projectile 11 and the propellant charge sleeve 12 is a strangle connection 14.
- the outflow openings 20 with the inlet cross sections 25 are in the initial region the weapon barrel 3, namely in the transition cone 6. There is a short Distance between the inlet cross section 25 and a sleeve mouth 17 of the propellant charge sleeve 12th
- a guide ring 16 of the projectile 11 abuts the sleeve mouth 17 this distance. In terms of its width, it is about half of the Transition cone 6 and the other half in the inlet cross-section 25.
- the inlet cross-section 25 is essential with its length 26 in the direction of the main axis 5 smaller than the total length 29 of a rod powder stored in the propellant charge sleeve 12 30th
- a width 27 of the inlet cross section 25 on the unwound drawn wall section the weapon barrel 3 corresponds approximately to 3 times its length 26.
- the stick powder packed in the propellant charge sleeve 12 burns 30 as a whole in the propellant charge sleeve 12. Should one or more rods 31 forward - that is, moved in the weft direction, so forms the inlet cross-section 25 an effective restraint for the rods 31.
- the rods 31 abut a wall 19 of the outflow opening 20 and burn out with yours parts protruding from the propellant charge sleeve 12 in the region of the transition cone 6. This ensures that the rod powder 30 is completely in the cartridge chamber 10 burns.

Description
Der konstruktive Aufwand an der Waffe ist klein. Auch ist die Munition kostengünstig, da eingeführte Treibladungshülsen verwendbar sind. Diese Treibladungshülsen werden in einfacher Weise mit Stangenpulver gefüllt.
Claims (4)
- Rückstoßarme Maschinenkanone (1) mit Munition (13) und einem Patronenlager (10) im Waffenrohr (3), wobeidadurch gekennzeichnet,die einteilige Munition (13) aus einer Treibladungshülse (12) mit Geschoß (11) besteht; undim Waffenrohr zwischen dem Mündungsende des Waffenrohres und dem Hülsenmund (17) der Treibladungshülse wenigstens eine Abströmöffnung (20, 25) mit anschließender Laval-Düse vorgesehen ist,daß die Treibladung als Stangenpulver (30) ausgebildet ist und die axiale Länge (26) des Einlaßquerschnitts (25) der Abströmöffnung (20) sehr klein ist gegenüber der Länge (29) des Stangenpulvers (30).
- Maschinenkanone nach Anspruch 1,
dadurch gekennzeichnet,
daß die Abströmöffnung (20) im Bereich des Übergangskonus (6) des Waffenrohres (2) liegt, bzw. die Abströmöffnung (20) bzw. der Einlaßquerschnitt (25) durch die Geschoßanfangsbewegung freigebbar ist. - Maschinenkanone nach Anspruch 1,
dadurch gekennzeichnet,
daß der Beginn des Einlaßquerschnittes (25) kurz nach dem Hülsenmund (17) in einem Abstand von ca. 1 bis 3 mm liegt. - Maschinenkanone nach Anspruch 1,
dadurch gekennzeichnet,
daß der Einlaßquerschnitt (25) bei abgewickeltem Rohrinnenumfang in radialer Richtung eine Breite (27) aufweist die etwa dem 3-fachen der Länge (26) in axialer Richtung entspricht.
