Definitions

  • the invention relates to a propellant charge according to claims 1, 2 and 3 and a method for their production.
  • DE - A 3 205152 may be mentioned as an example of this. It relates to a propellant charge for case ammunition and a method for its production, by means of which the capacity is to be increased compared to the known propellant charges, without at the same time resulting in increased workload and human risk from solvent vapors, as is the case with the propellant charge according to GB-A 1 415284 the case is.
  • the propellant charge powder bodies are compressed in the propellant charge sleeve by applying external pressure and without the addition of binding agents and / or solvents to a charge density of between 1.0 and 1.5 g / cm 3 and are elastic to plastic with an almost uniform or gradually different compression deformed, partial quantities with the same or different pressures being compressed in sections uniformly or gradually differently in the propellant charge sleeve.
  • the measures described there are aimed, in particular, at increasing the mass to be accommodated in a given propellant charge sleeve by compressing the entire propellant charge, possibly in partial quantities.
  • the take-off gas pressure as the one with which a new weapon barrel is loaded one or more times to check its safety. This gas pressure is close to the design gas pressure, mostly a little below it;
  • the object of the invention and its solution is directed to a propellant charge with a structure by means of which the increase in the maximum gas pressure occurring during the shot development can be influenced with increasing temperature until it is eliminated in the upper operating temperature range.
  • the starting point is a propellant charge powder for which a p, T curve according to the above-mentioned diagram exists in the case of loose bulk and without binding agent and / or solvent, and in a first example from a corresponding total mass N of the propellant charge.
  • a first portion of preferably about 50 to 80% is at least partially compressed. This will be discussed in more detail later.
  • the above-mentioned pressure increase can advantageously be influenced with increasing temperature until it is eliminated.
  • the increase in performance consists in the possible firing of a weapon tubes, which is designed for a certain maximum gas pressure, with a propellant charge that would no longer be permitted if the propellant powder was poured loose due to the steep rise in the p, T curve at higher operating temperatures.
  • the effective area of a press ram for compression can correspond to the clear internal cross section of the propellant charge sleeve, and the first portion can be compressed overall.
  • the propellant charge according to the invention of an at least partially combustible propellant charge sleeve is to be incorporated - this can be the case with ammunition in the caliber range below 20 mm to over 120 mm - it is advisable to compress the first portion in a comparatively smooth-walled device for which the pressure load when compressing the first share is designed. From this device, the compressed - possibly, as in the case of the bottle sleeve, only partially compressed - first part can be transferred into the aforementioned propellant charge sleeve by axial pressing. In order to avoid disadvantageous wall friction, a thin-walled tube can be arranged in the propellant charge sleeve before being transferred and then removed again.
  • a curve Sp N illustrates the behavior of a propellant charge from a propellant charge loosely poured into a propellant charge sleeve.
  • the curve in question shows that in the upper service temperature range a horizontal limit G1, which indicates the mean maximum permissible gas pressure for a first weapon barrel, is exceeded by the curve Sp n in the steep slope (dashed part). The propellant charge is therefore unsuitable for the relevant temperature range.
  • a curve S YN is entered in FIG. 1b for the loose propellant charge.
  • a curve Ep N in Fig. 1a shows the behavior of a propellant according to the invention, the mass N of which corresponds to that of the loosely poured propellant.
  • the curve Ep N remains flat under the limit G1: the method according to the invention consequently assumes the propellant charge has the same mass N - in both cases it is assumed that the propellant sleeve is the same - the suitability of the propellant charge for the weapon barrel in question achieved upper operating temperature range. This results in an increase in performance in the expanded sense mentioned at the beginning.
  • FIGS. 2a and 2b each again show two curves, namely S PN and E pM as well as S vn and E vM .
  • Fig. 2a is for a second weapon barrel, which is more resilient than the first gun barrel mentioned in connection with Figs. 1a and 1b.
  • a horizontal limit G2 is consequently associated with a higher pressure than the limit G1 in FIG. 1a.
  • the corresponding curves Sp N and S YN correspond to those from FIGS. 1a a and 1b, ie there is the same propellant charge of mass N in bulk.
  • the two corresponding curves Ep M and E YM characterize the behavior of a propellant charge according to the invention, the mass M of which is greater than that of the propellant charge of bulk (mass N) known from FIGS. 1a and 1b.
  • FIGS. 1a and 1b are again based on the same propellant charge sleeve and the same propellant charge powder.
  • the propellant charge in bulk is now usable, but from the course of the curves Ep M and E VM for the propellant charge according to the invention, the increase in interior ballistic performance in the conventional sense mentioned above compared to the propellant charge in bulk is clearly recognizable.
  • a modified but similar course of the curves Ep M and E VM can be achieved when using different propellant powders.
  • FIG. 3 shows a device V1 for carrying out the method according to the invention in a bottle-shaped propellant charge sleeve 10 with a sleeve wall 11 and a sleeve base 12.
  • a threaded bore 14 is provided in the sleeve base 12 for a propellant charge lighter.
  • the propellant charge sleeve 10 ends on the upper side in a sleeve neck 16.
  • the device V1 consists of a thick-walled circular cylindrical tube 18 with an inner flange 19 on the upper side.
  • a base piece 20 engages in the tube 18 on the underside and, in addition to a central axial receiving bore 22, has horizontal locking bores 21. The latter correspond to locking bores 18 ' in the tube 18.
  • the propellant charge sleeve 10 is received on the bottom side in the base piece 20, with fixing means 23 engaging through the bores 18' and 21 in an extraction groove 24 on the sleeve bottom side.
  • the propellant charge sleeve 10 has first been inserted with the base piece 20 in the direction of an arrow 54 into the tube 18, aligned with the central longitudinal axis A.
  • the sleeve neck 16 is located in the area of a coaxial circular opening 26 in the inner flange 19.
  • a funnel 28 is placed on an unspecified upper surface of the inner flange 19 and is surrounded by two spacer rings 30 and 32 in the case shown.
  • a circular cylindrical press die 34 with a press surface 38 on the underside has a fixing groove 36 in the upper free end. With the latter, the press die 34 is received in a holder 40 with radial bores 42. Only indicated fixing means 43 in the bores 42 engage in the groove 36 and fix the press ram 34 in the holder 40.
  • a first portion of a propellant charge is poured in the form of loose bulk powder through the funnel 28. This first portion is about 50 to about 80% of the total mass of the propellant to be incorporated.
  • the holder 40 is moved in the direction of an arrow 52 with the press ram 34 fixed therein, with a prescribable pressure being applied.
  • the pressing surface 38 comes into contact with a surface of the bed, not shown, and a part 46 of the first portion 44 is compressed. Since the outside diameter of the plunger 34 is smaller than the inside diameter of the propellant charge sleeve 10 in the region of its wall 11, an annular cylindrical cavity 48 remains, in which a small amount 50 of uncompressed propellant charge powder remains.
  • the compression of the part 46 of the first portion 4 is completed as soon as a lower annular surface 41 of the holder 40 touches an upper annular surface 32 of the upper spacer ring 32.
  • the holder 40 is moved with the press ram 34 in the direction of an arrow 54 until the funnel 28 is released. A second portion of the propellant charge remaining as the remainder is then loosely poured onto the first portion 44.
  • a dummy body 15 is arranged in the threaded bore 14 for the propellant charge lighter and in the receiving bore 22 of the base piece 20.
  • the part of the dummy body 15 protruding into the interior of the propellant charge sleeve 10, which is not described in more detail, is essentially the same dimension as the propellant charge lighter. Therefore, after removing the dummy body 15, the propellant charge lighter can easily be inserted into a channel 15 ' , which remains in the compressed part after removing the dummy body 15.
  • FIG. 4 shows a device V2 with a circular cylindrical tube 60 of sufficient wall thickness, in which a bottom piece 62 is inserted on the underside.
  • the latter has a central axial threaded bore 64 for receiving a dummy body 66.
  • a press ram 68 the outside diameter of which corresponds to the inside diameter of the tube 60, has a pressing surface 70 on the underside and an actuating rod 72 on the rear.
  • a central axial bore 72 ′ creates an interior space 73 that extends into a free upper end 75 of the rod 72. Vent holes 74 'connect the interior 73 with the surrounding atmosphere.
  • Radial bores 79 are provided in a holder 76.
  • Bolt-shaped fixing means 68 grip through this and fix the pressing die 68 with its rod 72 in the holder 76 via recesses 75 '.
  • a spacer ring 80 has a central opening 80 ′ which is adapted to the outside diameter of the rod 72.
  • the spacer ring 80 lies with a flat underside surface 81 ′ on an upper-side flat circular ring surface 61 of the tube 60.
  • the spacer ring 80 After the spacer ring 80 has been pushed over, it is fixed in the holder 76 and moved in the direction of an arrow 82 along a central longitudinal axis A while applying pressure against the loose powder filling of the first portion of the propellant charge.
  • the dummy body 66 projecting over a top surface 63 of the base piece 62 corresponds essentially to the dimensions of a propellant charge lighter.
  • the ram 68 moves downward, its free end 67 gets into the bore 72 ', the air being able to escape from the interior 73 through the ventilation bores 74'.
  • the first portion 86 of the propellant charge is compressed as soon as the receptacle 76 with its circle on the underside ring surface 77 touches the top surface 81 of the spacer ring 80.
  • the propellant charge is to be incorporated in a circular cylindrical inner cross section, not shown, of a metallic propellant charge sleeve, this can be provided with the dummy body 66, in which the inner diameter of the propellant charge sleeve tube 60 is inserted from below from below; in this case, the outside diameter of the press ram 68 must be adapted to the inside diameter of the metallic propellant charge sleeve, not shown.
  • the propellant charge sleeve 90 has a base 94, for example made of metal, with a central axial threaded bore 96 for a propellant charge lighter 98.
  • a combustible part 100 of the propellant charge sleeve 90 is fixedly connected to the bottom 94.
  • the first portion 86 of the propellant charge solidified in the device V2 according to FIG. 4 is now to be transferred into an interior space 97 of the propellant charge sleeve 90.
  • a metal sleeve 102 which is adapted to the inside diameter of the combustible part 100 and is shown in the drawing as excessively thick-walled for clarification, is introduced into the interior 97.
  • the arrangement according to FIG. 5 is fixed under the device V2 in alignment with the axis.
  • the propellant charge lighter 98 gets into a channel 88 formed by the dummy body.
  • the smooth metal sleeve 100 on its top edge 104 becomes one Arrow 108 removed from the propellant charge sleeve 90 again, and the second portion of the propellant charge is applied as loose bulk powder.
  • the press ram 34 has a central axial bore for the longer dummy body and then, if appropriate, also has a ventilation bore as in the device V2 in FIG. 4 must be provided.
  • the spacer rings 30, 32 and 80 are interchangeable, so that the penetration depth of the press ram 34 and 68 can be changed in order to achieve a predetermined compression of the respective first portion 44 and 86 of the propellant charge.
