Definitions
- the invention relates to a cartridge with a launch tube open on both sides, in which a projectile and a propellant charge cartridge are arranged.
- Cartridges with a launch tube open on both sides are used in recoil-free barrel weapons, for example in so-called nozzle cannons and rocket-propelled grenades.
- the shell impulse is compensated for by the rocket-propelled grenade by means of a countermass emerging from the launch tube in the opposite direction of the projectile.
- the propellant charge cartridge is located in the launch tube between the floor and the counter mass.
- the launch tube has radial ignition bores in the area of the propellant charge cartridge, in which igniters sit, which ignite the propellant charge in the propellant charge cartridge directly from the radially outside.
- the launch tube is mechanically weakened by the ignition holes, so that the use of lighter and weaker materials for the launch tube, for example plastic tubes reinforced with aramid fibers, is not possible.
- the object of the invention is to improve the igniter of a recoil-free cartridge.
- the cartridge according to the invention has a non-electrical ignition line which is connected to the propellant charge cartridge and through which the propellant charge can be ignited.
- the ignition line is attached axially to the propellant charge cartridge and is led out of the launch tube at an axial end of the launch tube. After the cartridge has been inserted into a firing device, the free end of the ignition line is connected to a firing device of the firing device. An ignition pulse is therefore no longer supplied to the propellant charge cartridge by the shortest possible route from the radially outside directly into the propellant charge cartridge, but via a detour through one of the two longitudinal openings of the launch tube.
- the launch tube can therefore be free of radial openings and is no longer weakened, particularly in the area of high explosion forces, namely in the area of the propellant charge cartridge.
- the non-electrical design of the firing lead excludes undesired, electrically induced firing impulses, which cannot be ruled out when using electrical leads, and therefore guarantees a high level of interference.
- the ignition cable can be led out of the rear opening of the launch tube facing away from the projectile.
- the ignition line is a pyrotechnic ignition line.
- the ignition line can be designed as an internally hollow ignition transmission tube which has a non-explosive explosive coating on the inside. After lighting a primer u. At the free end of the ignition transmission hose, the explosive is ignited on the inside of the ignition transmission hose, whereupon a shock wave propagates at high speed through the ignition transmission hose. The running time of the shock wave through the ignition transmission hose is so short even with longer hoses that the delay between the ignition of the ignition transmission hose and the ignition of the propellant charge is sufficiently short.
- the design of the ignition line as an explosive-coated ignition transmission hose offers short ignition times and a high degree of interference immunity, reliability and durability.
- a booster for igniting the propellant charge is arranged in the axial center of the propellant charge cartridge, the ignition line opening axially into the booster.
- the booster contains a booster charge that the weak ignition pulse from the ignition line as far reinforces that the propellant charge can be ignited directly or with the interposition of an additional charge. It is only when a booster is used that an explosive-coated ignition transmission hose can be used as the ignition line.
- the booster preferably has an explosive booster charge in an insulating cylindrical booster housing, the booster housing having radial openings in the region of the booster charge.
- the booster charge is thus insulated by the booster housing in such a way that the combustion gases and particles emerge from the cylindrical booster housing only in the radial direction. This avoids an axial impulse on the booster, so that the booster is in any case not driven axially out back of the launch tube, where it would represent a dangerous projectile. This ensures a back-tube safety of forty meters with rocket-propelled grenades.
- the hot gases and particles emerging radially outward from the booster housing reach the bypass or the propellant charge of the propellant charge cartridge in the shortest radial way, so that the propellant charge is ignited with little delay.
- the booster is preferably firmly connected to the projectile end of the propellant charge cartridge.
- the end of the propellant cartridge on the projectile side is ejected axially forward from the firing tube after the propellant charge has been ignited, hurrying behind the projectile.
- the booster is also carried axially forward and ejected from the front of the launch tube. This ensures that the booster is never ejected from the rear of the launch tube, so that the safety of the rear tube cannot be impaired.
- the launch tube is preferably free of radial openings.
- the radially opening-free design of the launch tube enables the use of light, non-metallic materials for the launch tube, for example plastic tubes reinforced with fiber fibers, among others.
- Fig. 2 shows a propellant charge cartridge with a booster of the cartridge of Fig. 1 and
- Fig. 3 shows the booster of Fig. 2 in longitudinal section.
- a so-called apelooka 10 is shown, as it is used to combat armored vehicles.
- the Panzerfaust 10 consists of a launcher 12 to which an exchangeable cartridge 14 is attached.
- the cartridge 14 essentially consists of a launch tube 16 open on both longitudinal sides, in which a projectile 18, a propellant charge cartridge 20 and a countermass 22 are arranged approximately in the center and one behind the other.
- the projectile 18 is a conventional projectile for defense against armored vehicles.
- the counter mass 22 consists of pressed iron powder.
- the launcher 12 has holding elements for holding and fixing the replaceable cartridge 14.
- the launcher 12 also has a handle 24, a rear handle 26 and a front handle 28.
- a trigger 30 with a trigger lever 32 is arranged in the area of the front handle 28.
- a trigger linkage, not shown, is actuated by the trigger lever 32 and triggers a striking movement of a striking pin in a trigger mechanism 34.
- the propellant cartridge 20 shown in detail in FIG. 1
- Cartridge housing 38 with an annular disk-shaped front wall 40 on the projectile side, a corresponding rear wall 42 and a cylindrical outer peripheral wall 44 on. All walls 40-44 are made of paper or cardboard.
- a front propellant charge 46, a rear propellant charge 48 and, separate the two propellant charges 46, 48 from one another, an additional charge 50 made of an ignition mixture are arranged in a ring shape within the cartridge housing 38.
- an approximately cylindrical cavity 52 is continuously provided in the longitudinal direction, into which a booster 54 is inserted.
- the booster 54 contains an explosive booster charge 58 which is arranged axially approximately at the level of the additional charge 50.
- the booster 54 has a cylindrical booster housing 60, the front of which is closed.
- the booster housing 60 is made of aluminum.
- the front third of the booster housing 60 is filled with an inert filler plug 62.
- the filler plug 62 is made of polyethylene, but can also consist of aluminum.
- the front filler plug is not required for versions of the lighter in a shorter design.
- the middle third of the booster 54 is filled with the booster charge 58, while the rear third of the booster housing forms a receptacle for an ignition line 56 and contains a transfer charge 64 between the end of the ignition line and the booster charge 58.
- the ignition line 56 is anchored to the booster housing 60 by a constriction 66 produced by crimping.
- the booster-side end piece of the ignition line 56 is surrounded by a cylindrical sealing element 68 made of plastic.
- the booster housing 60 has a plurality of radial openings 70 in the region of the additional charge 50, through which the reaction products of the ignited booster charge 58 can escape radially outward in order to ignite the additional charge 50.
- the front end of the booster housing 60 is glued into a fastening bush 61, which in turn is glued to the front wall 40 of the cartridge housing 38.
- the booster 54 is connected to the trigger mechanism 34 outside the cartridge 14 by a non-electrical ignition line 56 designed as an ignition transmission hose 57.
- the ignition line 56 is a hollow ignition transmission hose 57 which is internally coated with a non-explosive Explosives is vaporized.
- the ignition line 56 is approximately 1 cm long and is led out of the launch tube 16 through the rear opening 17, and from there is placed forward to the trigger mechanism 34.
- a primer cap 72 is arranged, which is ignited mechanically by striking the fired striker and thereby triggers the shock wave in the firing transmission tube 57.
- the projectile 18 is fired by a chain of firing processes. "First of all, by pulling the trigger lever 32 of the trigger 30, a firing pin is unlocked in the trigger mechanism 34 so that the firing pin hits the firing cap 72 at high speed and thereby ignites the firing cap 72.
- the detonator coating ignites the explosive coating in the ignition transmission hose 57, as a result of which a shock wave propagates at high speed through the ignition line 56 from the mechanism 34 to be triggered in the direction of the booster 54.
- the shock wave alone is not sufficient for the booster charge, the additional charge 50 or the To ignite propellant charge 46, 48 directly with great reliability, so that the shock wave entering the booster 54 first ignites the transfer charge 64, which in turn ignites the actual booster charge 58. Since the booster housing 60 has good insulation properties After the booster charge 58 has been ignited, the reaction products, that is to say hot particles and hot gases, are expelled essentially radially outward through the radial openings 70.
- the charge 50 When the reaction products emerge in the exclusively radial direction, the charge 50 is ignited and in any case no radial impulse is brought about on the booster housing 60, so that the booster housing 60 remains in the propellant charge cartridge 20 via the fastening bushing 61.
- the front and rear propellant charges 46, 48 are ignited by the escaping reaction products of the auxiliary charge 50 that is now to be ignited, which cause a strong explosion.
- the countermass 22 is driven backwards and the projectile 18 out of the launch tube 16.
- the cardboard cartridge housing 38 is destroyed, the cartridge front wall 40 in is driven out of the launch tube 16 in each case following the projectile 18.
- the front wall 40 drags the booster 54 glued to it via the fastening bushing 61 and thereby pulls the booster 54 forward out of the launch tube 16. This ensures that the booster 54 cannot emerge from the rear of the launch tube 16, where it would constitute a dangerous projectile. This measure ensures a back tube safety of 40 meters.
- the ignition delay times of the ignition described via the non-electrical ignition line 56 are uniform and sufficiently short.
- the following interior ballistic parameters are also satisfactory, as tests have shown.
