Definitions
- the invention relates to a propellant charge arrangement for tubular weapons or ballistic drives consisting of a compact load and an electromagnetic radiation emitting Ignition system, the Kompaktla Plantg a radiation-absorbing Medium is assigned.
- the propellant burns up and the projectile accelerates is a dynamic process that is extremely within a short time, within which the gas evolution due to the propellant charge not only on the mass of the projectile coordinated, but also takes into account the fact must be that with the acceleration of the projectile increases the volume to be filled by the propellant.
- These overlapping processes must in turn be like this be coordinated so that the projectile is the desired one Muzzle velocity reached.
- the gas pressure-time curve which is generally one Gaussian curve is similar, i.e. the pressure increases exponentially to a maximum pressure and falls a little less steeply increasing acceleration of the projectile towards the muzzle exponentially.
- the conversion rate shows a more symmetrical course of the Gauss curve the propellant charge.
- Propellant charges with a high Laduncis density i.e. a large one Ratio of the mass of the Ladladigig powder to its volume used. This is for a high muzzle velocity of the projectile required high charge density through large-volume propellant charges with regular Arrangement of the charge particles achieved.
- the ignition takes place by chemical igniters, e.g. Nitrates, which mechanical Ignition devices, such as firing bolts, or electromechanical Ignition devices require.
- Tubular powder or cylindrical multi-hole powder used which of channels for the passage of the swath of the Zündmit means are penetrated so that the combustion of the propellant charge a large surface area is initiated. This will, however the propellant density is reduced and the muzzle velocity of the projectile thereby reduced. Furthermore the gas pressure drops immediately after reaching his Maximum exponentially again. While small caliber Tube weapons, such as anti-aircraft guns or tank cannons, in this way, burn-off times of 1 to 10 ms can be achieved, are the burn-up times for large-caliber barrel weapons, like artillery pieces, much longer.
- DE 195 46 341 A1 describes a propellant charge with a secondary arranged in a cylindrical sleeve Explosives and an initial explosive arranged next to them, which by coupling laser radiation is ignited.
- a high sales speed of the Propellant charge when burning can be done with such an arrangement cannot be reached because the initial explosive is only on one a side of the secondary explosive facing a light guide is arranged and the latter consequently when igniting the load is not broken up and dismantled spontaneously.
- This also applies to another known version (GB 2 267 330 A), in which at the rear end of the Propellant charge applied an infrared absorbing layer is affected by the laser beam.
- The. DE 35 42 447 A1 shows an ignition mixture which can be activated by means of laser radiation and which contains 10 to 30% by mass of a hot-burning fine particulate metal powder, in particular zirconium, titanium or boron, 60 to 80% by mass of an oxidizing agent, in particular lead oxide, and 1 to Contains 5% by mass of carbon black.
- a hot-burning fine particulate metal powder in particular zirconium, titanium or boron
- an oxidizing agent in particular lead oxide
- 1 to Contains 5% by mass of carbon black To ignite a propellant charge, the ignition mixture is arranged in a narrow geometric area of the charge powder of a few mm 2 , on which the laser beam strikes. In this case, too, spontaneous conversion of the charge powder is not possible.
- US Pat. No. 3,601,054 A in which only one squib enriched with electrical conductors is ignited electromagnetically and is therefore implemented more spontaneously.
- the invention has for its object a propellant charge arrangement propose avoiding the aforementioned Disadvantages when burning the ideal, trapezoidal The course of the pressure-time curve approximated as far as possible is.
- this object is achieved with a propellant charge arrangement according to the preamble of claim 1 (GB 2 267 330 A) solved in that the electromagnetic radiation a wavelength of about 1mm to about 1m (microwaves) and that in the compact charge at least one microwave absorbent medium stored and distributed can be activated by means of the ignition system to the compact charge break down into fragments when the ignition system is triggered and the fragments in the generated when the compact charge burned Accelerate gas volume.
- the electromagnetic radiation a wavelength of about 1mm to about 1m (microwaves) and that in the compact charge at least one microwave absorbent medium stored and distributed can be activated by means of the ignition system to the compact charge break down into fragments when the ignition system is triggered and the fragments in the generated when the compact charge burned Accelerate gas volume.
- the compact load Due to the internal ignition of the propellant charge arrangement according to the invention in the microwave absorbing areas the compact load is broken up in a defined sequence disassembled.
- the structure of the compact load and its arrangement as well as that of the ignition system can be chosen so that Fragments with a relatively regular geometry arise, which consequently also offer relatively regular surfaces, which in turn ensure regular burning and burning. It is also due to the increased introduction of microwaves absorbent medium in defined areas of the Propellant charge possible to ignite these areas earlier and to control the burn-up depending on the time.
- the fragments resulting from the fragmentation have a high burn-up area and will result in the burn-off the gas volume developing the propellant accelerates and fully implemented there.
- the propellant charge arrangement according to the invention makes use of it dispensable from chemical detonators, which makes them is easier and safer to handle. Still requires they do not require the initiation of such chemical igniters mechanical or electromechanical ignition devices, so that they are inexpensive due to their simple structure is.
- the density of the propellant charge arrangement according to the invention can be compared to conventional propellant charges increase by the inclusions of the microwaves absorbent medium are designed very thin, so that this in comparison to the known propellant charges for channels provided through a swath penetration clearly require less space.
- the formation of fragments with a relatively regular geometry and consequently high erosion surface can be particularly thereby achieve that the compact charge one in has a substantially regularly structured structure or the microwave absorbing medium in the compact charge is stored in a regular arrangement.
- the Ignition system then becomes the compact charge along the areas from the microwave radiation absorbing medium broken up and in corresponding regular fragments accelerated inwards, the surfaces forming ensure proper burning and burning.
- the compact charge can, for example, of essentially geometrically regularly arranged layers of the microwave radiation absorbent medium, the layers preferably being essentially grid-like are arranged.
- the medium absorbing microwave radiation Layer thickness is expediently between 1 and 1000 microns.
- the compact load can also be of essentially geometric regularly arranged channels from which the microwave radiation absorbent medium, the The diameter of the channels suitably between 1 and 1000 microns is.
- the one stored in the explosive can be distributed and possibly microwaves enveloping it absorbent medium in any way, e.g. by heating and possibly associated with the heating Thermal expansion and / or evaporation, photoreaction, fission, Transfer to a plasma state or the like for ignition the compact load or for fragmentation thereof to lead.
- the compact charge can either essentially be powdery, the powder particles one Have structure of the aforementioned type, or the compact charge is designed in the manner of a molded part, which e.g. can be brought into a cargo space of a barrel weapon.
- the intensity the microwave radiation of the ignition system controllable is.
- the radiation can influence the pressure-time course in a targeted manner e.g. on the one hand through targeted reignition the resulting fragments or by heating the combustion gases, by bringing the microwave radiation to the resonance frequency the same is adapted.
- the microwave radiation used to ignite the compact charge be adapted to the ambient conditions, so that e.g.
- the microwave radiation can, for example, by means of a emitter reaching into the compact charge, such as an antenna, be coupled into the compact charge, or is it into the compact charge by means of emitters surrounding the compact charge be coupled.
- a emitter reaching into the compact charge such as an antenna
- the compact charge be arranged in a cartridge, which in particular for handling a substantially powdery Propellant charge is advantageous.
- frequency range preferably carbon, especially carbon black, used.
- Fig. 1 shows a schematic cross section through a Gun 10 with a barrel 12 (shown broken off) and a cargo space 11 in which a propellant charge 4 in Form of a compact load is housed.
- the compact load 4 e.g. from a powder from an explosive or an explosive mixture and distributed one embedded medium absorbing microwave radiation, e.g. RuB. As shown in Fig. 2, this is absorbent Medium 3 in the propellant charge particles 1 of the compact charge stored in a regular order, taking the explosive 2 interspersed in layers.
- the barrel 12 there is a projectile 13, the Rear protrudes into the cargo space 11.
- an ignition system 5 with a controllable one Microwave generator 6 is provided.
- the one from the microwave generator 6 generated electromagnetic radiation is over an antenna 7 can be coupled into the cargo space 11.
- the particles 1 along the compact charge 4 the soot layers 3 in substantially regular Fragments disassembled and the fragments in the on Compact charge 4 accelerated gas volume generated. at the same time the burning of the fragments begins and is implemented the fuel fragments from the compact load 4 instead of.
- the projectile 13 will be on a longer distance evenly applied with approximately constant pressure and leaves barrel 12 with the desired high muzzle velocity with possibly reduced muzzle pressure.
- FIG. 3 shows the pressure-time profile of a conventional propellant charge with curve 15.
- the pressure p increases exponentially to a maximum pressure p max and drops a little less steeply with increasing acceleration of the projectile towards the barrel muzzle.
- the propellant charge arrangement according to the invention can generate a pressure curve according to curve 16, which shows a pronounced pressure plateau 17 with a time-delayed pressure drop when the rise is somewhat premature.
- the maximum pressure p max can be reduced with an increased drive power, for which the pressure-time integral is decisive, or an increased drive power can be achieved with the same maximum pressure.
