Definitions
- the invention relates to an ignition system for propellant charges according to the preamble of claim 1.
- the invention relates further relates to a method for producing such Ignition systems.
- DE 42 23 735 A1 discloses a low-pressure ignition system in particular for modularly structured propellant charges of large calibres Ammunition known to achieve short ignition times the individual propellant charge modules each have a perforated support tube made of a combustible material which encloses an axial ignition channel. On the propellant powder facing side is an ignition transfer charge intended.
- This essentially consists of Propellant pellets, each with a very thin Ignition mixture of about 1/10 mm from in nitrocellulose bound black powder are coated.
- the pellets coated with the ignition mixture are a combustible low pressure pipe, e.g. a shrink tube, arranged.
- the support tube in addition to the actual ignition transfer charge on its inside and outside with a thin layer of the igniter mixture mentioned above be coated.
- the present invention is based on the object To create ignition system, which is multi-part for lighting Charge structures is suitable for a short implementation time Ignition of the propellant charge is simple and inexpensive can be produced. Furthermore, a method of manufacture is said to of such an ignition system are disclosed.
- the invention is based on the idea of Ignition transfer charge not coated with an ignition mixture Pellets to use, but a 1.0 to 3 mm use thick pyrotechnic composite rigid foam layer which is largely coarse-pored in structure (Sponge structure).
- the relatively thin propellant powder and surface layers facing the support tube should, however, preferably be tightly closed as an integral layer to the required protection of the rigid foam layer to ensure against moisture and water.
- Such a hard foam layer according to the invention ensures a safe, even at low temperatures, fast and reproducible ignition of the propellant powder.
- the ignition transfer of the rigid foam Surprisingly, relatively independent of its structure (e.g. the degree of porosity, the skin characteristics, the local density fluctuations etc.). This means that to the parameters for the production of rigid foam and its structure in terms of temperature, pressure and drying time etc. no high-precision demands are made have to.
- the ignition system according to the invention has proven to be particularly advantageous proven when the pyrotechnic rigid foam Addition of cellulose and / or plastic fibers contains. On the one hand, this addition increases the strength and therefore the mechanical stability of the rigid foam is significantly increased. On the other hand, the use of such enables Fibers also work with coarse-grained black powder. While for example when using the in DE 42 23 735 A1 Ignition mixture described for the application of a uniform Film on the support tube or on the propellant pellets the black powder only grain sizes of maximum 0.1 mm may have in the layer according to the invention the grain sizes of the black powder are up to 1.5 mm. Nevertheless results from the use of granular black powder a hard foam layer, which has a high internal strengthening of the Has black powder and firmly on the respective support tube is liable.
- the big advantage of using a coarse-grained black powder is that the loose distribution of the relative large black powder grains in the foam structure with their large grain surface at the moment of ignition and at the moment of flame transmission on the propellant powder with hardly increased Provide ambient pressures for the greatest liveliness values.
- the cellulose or Plastic fiber content of the foam between about 0.2 and 5 % Should be.
- the fiber content should preferably be approximately 1-3% by weight.
- the inventive method is characterized in that First, nitrocellulose (NC) dissolved in an NC solvent becomes. Then that which is insoluble in the NC solvent becomes Cellulose and / or plastic fiber mixture introduced into the solution and distributed homogeneously in it. Then after that Black powder and possibly other additives, for example a plasticizer, mixed and homogeneous in the solution can be distributed, the ignition mass composed in this way either directly on the support tube or on a separate one Shaped body applied and preferably at temperatures between 30 to 60 ° C and a slight negative pressure dried be so that the solvent evaporates and thereby inside the desired coarse-pored and porous structure as well creates a coherent surface film on the surfaces.
- NC nitrocellulose
- the method according to the invention has i.a. the advantage that Production of the rigid foam does not use a separate blowing agent must be because the solvent has this role takes over.
- nitrocellulose especially vinyl wool with a Proven nitrogen content of 11.5 to 12.5% nitrogen.
- solvent power of Highly nitrided nitocelluloses can also be used for shooting cotton (Nitrogen content> 13%) are used.
- NC solvent which also take on the role of blowing agent should have, among others, acetone, acetonitrile and various esters or ketones and suitable mixtures as proven suitable.
- a cellulose-fiber mixture can be used with good Successful cotton sinter or kraft pulp can be used.
- soft grain types are preferred usable, including those that differ Have compositions of the basic form, so not contain only 75%, but also 77% or 80% potassium nitrate.
- Dibutyl phthalate and other phthalates have become plasticizers proven as well as centralite which the otherwise relatively hard Make the structure of the foam more elastic and pliable.
- Fig. 1, 1 can be used in large-caliber guns Propellant charge module (see e.g. EP 0 306 616 B1), which essentially consists of a container 2 for Inclusion of propellant powder 3 known per se.
- a free ignition channel 4 is provided for a central ignition provided that the side of a support tube 5 from a combustible material is limited.
- the support tube 5 there are a plurality of openings 6.
- a pyrotechnic composite rigid foam layer 7 with an essentially three-layer structure (FIG. 2) is arranged on the side of the support tube 5 facing the propellant charge 3 as an ignition transfer charge.
- the surface layer 8 facing the propellant charge powder and the surface layer 9 facing the support tube 5 are each sealed (ie the density should be> 1 g / cm 3 ) and offer protection against moisture possibly penetrating into the rigid foam.
- the inner layer 10 lying between the surface layers 8 and 9 has a relatively porous and coarse-pored foam structure (ie the foam density should be between 0.4 and 0.9 g / cm 3 ).
- the surface of the support tube 5 facing the ignition channel 4 covers a thin pyrotechnic lacquer layer (ignition layer) 11.
- the hot ignition gases in ignition channel 4 ignite there both the pyrotechnic lacquer layer 11 and the openings 6, the surface layer 8 and then the coarse-pore Inner layer 10 with its ignitable black powder grains.
- Nitrocellulose is used to manufacture the pyrotechnic rigid foam (NC) (e.g. lacquer wool with a nitrogen content between 11.5% and 12.5% or shooting cotton with one Nitrogen content above 13%) in a solvent (e.g. acetonitrile) solved. Then a kraft pulp fiber mixture introduced into the solution and distributed homogeneously. Subsequently the black powder is preferably in the grain size range between 0.2 and 1.5 mm and optionally a plasticizer portion added. Furthermore, to increase the flame temperature and to accelerate the ignition reaction 2 to 12% (preferably 3 to 5%) magnesium and / or aluminum powder Solution mixed and distributed. The viscosity of a such a mixture has relatively high values ( ⁇ 5000 Pa * s) so that there is a pasty kindling.
- NC pyrotechnic rigid foam
- a solvent e.g. acetonitrile
- the pyrotechnic lacquer layer 11 for example applied by spraying and then dried.
- an approximately 1 to 3 mm thick layer of the kindling is e.g. through a slot die, onto the outer surface the support tube 5 with the aid of a metering piston pump pressed. Due to their thixotropic attitude by adding the cellulose fiber mixture, the Stand the ignition material on the support tube and adhere.
- the support tube is placed in a drying tunnel in which a temperature from 30 - 60 ° C and a negative pressure of approx. 700 mbar is present. As a result, the solvent escapes on the surface by evaporation.
- the igniter mass is poor in solvent and a coherent surface film is formed, which the corresponds to the surface layer designated 9 in FIG. in the Foams inside under the forming surface layer 9 the ignition mass by evaporation of the solvent and forms a hardening foam structure of a thickness that -depending on the selected layer thickness of the ignition material- between 0.5 and should be 2 mm.
- the vapors escape through pores the outer skin. They are put down in a cold trap and recovered the solvent.
- the carrier has a surface with screen holes and is hollow inside.
- the vapors can then enter the interior of the carrier be suctioned off when a slight vacuum is applied.
- the thickness can be determined by the temperature and the vacuum the hard foam layer and its porosity can be controlled. After the drying process, the pressure can be increased slightly Rigid foam layer covering the dimensions and contour of the Support tube has accepted, deducted from the carrier and on the prepared support tube can be pushed.
- the support tube is prepared by that it is on both sides, for example, in one spraying operation is painted.
- this varnish provides the Inner coating of the perforated support tube 5.
- On the other hand forms the outer coating of the support tube with the paint an adhesive connection between the support tube and the slid over Rigid foam molding.
