Definitions
- an ignition tube running in the middle of the propellant charge was provided in the past, which is directly connected to the propellant charge lighter and is designed as a structural unit with it.
- Such ignition tubes extend, for example, up to a third of the total length of the propellant charge and are known, for example, from DE 199 44 377 B4 or from EP 0 822 385 A1.
- the invention is based on the object of providing an ignition system for large-caliber ammunition which, with reduced gas pressure waves, allows the installation space for a penetrator to be increased.
- an ignition system for ammunition comprising at least one propellant charge igniter, and at least one ignition element designed to transmit ignition energy, which extends away from the propellant charge igniter.
- the ignition element is arranged at a distance from the propellant charge lighter.
- an ignition system for ammunition comprises at least one propellant charge lighter, at least one propellant charge and at least one ignition element designed to transfer ignition energy to the propellant charge, which extends away from the propellant charge lighter in the propellant charge.
- the at least one ignition element is arranged at a distance from the propellant charge.
- ammunition which comprises a projectile and an ignition system of this type or an ignition system which is further developed as described below.
- the ignition system can comprise at least one propellant charge and the ignition element can be designed to transfer ignition energy to the propellant charge.
- the ignition element preferably extends in the propellant charge away from the propellant charge lighter.
- the principle of the invention is based on a short propellant charge igniter which takes over the primary ignition or initiation of the propellant charge.
- at least one ignition element is provided according to the invention which, due to its design (geometric fixtures) and / or its nature (pyrotechnical measures), ignites the propellant charge as evenly as possible over the length of the propellant charge in order to create a gas pressure wave avoid.
- the primary aim is to provide free spaces and channels that allow the flame and the particles of the propellant charge lighter to get from the propellant charge lighter (rear) to the front part of the propellant charge, in order to do that there too Ignite propellant powder.
- round, oval and / or rectangular channels are introduced into the propellant charge in order to ensure that flames, particles and / or gas are transported with as little turbulence as possible.
- a pressure wave-free flow through the propellant powder would not be possible in the necessary firing times, since the propellant powder grains cause a strongly turbulent flow and thus prevent the ignition in the front part of the propellant charge in time.
- the at least one ignition element is preferably made of combustible materials such as cardboard or cardboard with nitrocellulose and binding agent.
- the at least one ignition element can contain pyrotechnic sentences in bound form (e.g. paint or glue), pressed into shaped pieces, loose bulk of pyrotechnic sentences or in textile form (small bags) packaged pyrotechnic mixtures or propellant powder.
- the at least one ignition element can be designed without ignition-enhancing substances. To ignite the cartridge, it is sufficient in this case to transport the flame, the at least partially burning particles and / or the hot gases through the at least one ignition element into the areas of the propellant charge remote from the propellant charge lighter.
- the at least one ignition element can be arranged at a radial distance from a center line of the propellant charge.
- the center line is a common center line of the propellant charge, the propellant charge igniter, the rotationally symmetrical case or cartridge base, the rotationally symmetrical case or cartridge rim and the projectile and the penetrator of the projectile.
- the at least one ignition element can be axially spaced from the propellant charge lighter with respect to a center line of the propellant charge.
- the at least one ignition element can be designed as a channel, tube and / or as a cylindrical element.
- the ignition of the propellant charge can be sufficient due to the flame, gas and / or particle transmission through the at least one ignition element to ignite the cartridge safely and with low pressure waves within the required period of time.
- the at least one ignition element extends in the direction of a propellant charge front, preferably at least as far as the center of the longitudinal direction of the propellant charge, in particular as far as the propellant charge front.
- the propellant charge front in the sense of the invention is an area of the foremost 10% of the propellant charge.
- At least one ignition booster charge can be formed separately from the propellant charge igniter and the at least one ignition element.
- the ignition booster charge ensures that the ignition energy reaches the at least one ignition element when the propellant charge igniter has too little ignition agent mass.
- One or more additional ignition boost charges can be used or combined.
- the position of the ignition boosting charges (in each case ignition means or propellant charge powder) can be in the area of the propellant charge igniter, in ignition transmission channels and / or in the propellant charge.
- ignition charges that can be initiated quickly can also be introduced onto or into the ignition boosting charges.
- the ignition element is arranged at a radial distance from the propellant charge igniter. Furthermore, it can be provided that the at least one ignition element is designed to pass on the hot gases and / or particles generated by the propellant charge igniter and / or the flame, hot gases and / or particles generated by the at least one ignition amplifier charge. This happens without the formation of an unwanted gas pressure wave.
- the at least one ignition element is designed to generate a flame, hot gases and / or particles.
- the at least one ignition element has an ignition rate or burn rate that is higher than that of the propellant charge.
- the ignition elements with active transmission of the ignition energy by pyrotechnic measures should have a higher or at least the same burn-through / ignition speed compared to the ignition of the propellant powder bed without auxiliary means (geometric fixtures). Ignition mixtures that react with the formation of hot particles should preferably be used.
- the ignition element is designed in such a way that the propellant charge can be ignited uniformly over the length of the propellant charge, preferably the entire length of the propellant charge.
- the at least one ignition amplifier charge and / or the at least one ignition element is designed in the form of an additional black powder, boron-potassium and / or ignition agent charge, in particular in the form of a bag or encapsulated.
- the ammunition is preferably a large-caliber ammunition, in particular in large-caliber such as 105, 120, 130, 140 or 150 mm. But it can also be ammunition of other caliber.
- the ammunition can preferably be cartridge-type ammunition.
