Definitions
- the invention relates to the problem of a separation point between the drum and the weapon housing of a recoilless / low recoil machine gun.
- a recoilless machine gun is known from http://www.waffenhq.de/flugmaschinee/rmk30.html and consists among other things of a weapon housing with a gas funnel, a kind Laval nozzle at the end and a weapon barrel / barrel.
- the ammunition supply takes place as shown from the front into a turret chamber of a drum. Between drum or turret chamber and weapon housing occurs in this separation point in practice due to structural conditions to a leak in the ignition, which can not be prevented by a seal between the drum and cartridge chamber.
- the DE 92 08 018 U1 discloses a firearm with a barrel and at least two cartridge chambers. These can be designed as a drum, but not directly connected, and rotated as a rotary drum or shifted as a sliding drum right / left / up / down.
- the invention addresses the problem of avoiding leakage occurring in the region of the separation point between the drum and the weapon housing.
- the invention is based on the idea to shift the separation point between the drum and the weapon housing in the drum itself and in each turret chamber or each cartridge chamber to integrate a nozzle or a nozzle attachment. This nozzle then interacts with the nozzle extension located in the weapon housing functionally as conventional.
- This solution has in addition to the advantage that there is no gap between the drum and the weapon housing in the ignition of the cartridge and thus the leak is removed, another positive effect, which is that a reduction of the load on a chamber and firing ring takes place in total.
- the respective cartridge chamber or the respective turret chamber with the cartridge therein is in alignment with the weapon barrel and the rear part of the weapon housing, which has the nozzle-like extension to the cartridge chamber.
- FIG. 1 shows parts of a recoilless weapon 100 known from the prior art, with a weapon housing 101, a drum 102 with drum housing 103, a nozzle 104 incorporated in the weapon housing 101, a plurality of cartridge bearings or chambers 105 n in one of the chambers 105 Cartridge 106. Between drum 102 and the respective cartridge chamber 105 is incorporated in each case a seal 107. The separation point T is formed between chamber 105 and the nozzle 104.
- the drum 102 To transport the cartridge 106 into a firing position, the drum 102 is rotated about an axis 108.
- a bobbin 110 for receiving a primary coil 111, which cooperates with a secondary coil 112 in the cartridge case bottom 109 functionally.
- the power transmission to the primary coil 111 is carried by the weapon housing 102 by means of cable 113.
- the cartridge 106 itself has the sleeve side 109 a cartridge ignition insert 114, which is ignited via the secondary coil 112.
- Fig. 2 shows the invention essential parts of the weapon 10 according to the invention with a weapon housing 1, a drum 2 with drum housing 3, a plurality of cartridge bearings or chambers 4 n .
- This weapon 10 is characterized in that in the respective cartridge chamber 4 n in the drum 2, a nozzle 5 n (or a nozzle approach) is involved.
- the nozzle 5 is further provided n each represents a bobbin 6 n for this carrier 6 n primary coil 8 contained integrated n.
- This ignition ring or the primary coil 8 n is electrically connected in a known manner with the secondary coil in the cartridge, which has the task to ignite the sleeve-side ignition insert (see Fig. 1).
- the current transmission to the primary coil is effected by a non-contact, preferably inductive transmission path 7 integrated between drum 2 and drum housing 3.
- a part 7.1 of the contactless transmission path 7 is moved with the drum 2, while the other part 7.2 remains stationary.
- the new separation point T is now formed between the respective nozzle 5 n and the drum housing 3.
- the operation of the new weapon 10 itself is conventional.
- the cartridge is fed from the front of the weapon 10 and brought by means of the drum 2 in the Verschussposition.
- the ignition of the cartridge via the transmission path 7 and the primary coil 8 n , which is electrically connected to the drum-side part 7.1 of the transmission path 7 (not shown in detail).
- the ignition signal is then forwarded to the secondary coil of the cartridge chamber 4 n and initiates the ignition.
- the drum 2 is further rotated after Verschuss and transported a new cartridge in firing position.
