Definitions

  • the invention relates to a throwing system for fog candles, explosive devices and the like, in which the firing is carried out by electrical ignition of a propellant charge, consisting of a launcher with at least one throwing cup and throwing bodies which can be used in the latter, the throwing cup having a launch tube open at both ends, which at its rear side can be closed by a removable base piece and project into the interior through the jacket electrical contact pins which are in an electrically conductive connection when the throwing cup is loaded with contact rings of the throwing body.
  • the throwing cups are designed for a certain effective mass and a defined recoil.
  • the generally introduced throwing cups with a diameter of 76 mm are suitable for firing active weights up to approx. 1100 g, with a recoil pulse of approx. 4.4 kN.
  • the invention has for its object to provide a throwing system with the features specified above, in which it is possible to use the known throwing cup, ie without interfering with the known throwing system, to shoot higher active masses and achieve greater ranges without thereby limiting To exceed recoil forces.
  • the basic idea of the invention is to integrate a longer tube into the known throwing cup, from which the larger active mass is fired with a lower powder charge.
  • the invention makes use of the known fact that the barrel length of a gun has a positive effect on the build-up of gas pressure in the gun barrel. This means that, to put it simply, a larger pipe length, with the correct design of the components, can achieve a greater range of the projectiles or, with the same range, can fire higher masses.
  • the larger tube length serves to fire a larger active mass with approximately the same range and with a lower recoil pulse.
  • FIG. 1 shows the throwing cup of a known throwing system with a launch tube 1, a mounting ring 2, a mounting block 3, in which the electrical contact pins 17 inserted into the interior of the launch tube 1 are not visible in FIG. 1, and a receiving collar 4 for the removable base 5.
  • FIG. 2 The conversion of this throwing cup by inserting an extension tube is shown in Fig. 2.
  • an extension tube 7 is inserted from the front in the direction of arrow E (FIG. 2), which has a retaining collar 8 acting as a stop on its outer circumference.
  • contact rings 9 are arranged on the circumference in a manner explained in more detail below.
  • the propellant charge assembly 10, which is explained in more detail below, is arranged on the closed rear side of the extension tube 7.
  • the retaining collar 8 lies against the front end of the launch tube 1, as can be seen, for example, from FIG. 4.
  • extension tube 7 with an inserted throwing body 14 is shown in more detail.
  • the extension tube 7 consists of a molded plastic part with a molded-on retaining collar 8 and circumferential grooves, in which contact rings 9 are arranged, which for example consist of a self-adhesive contact foil, preferably in a gold-plated design.
  • a propellant charge assembly 10 is arranged at the rear end of the extension tube 7, which is closed by a base 7.1. It has a propellant charge screw 12, which is screwed into a central opening of the base 7.1 by means of a receiving thread 13 and which contains the propellant charge and an ignition device and is connected to the contact rings 9 via conductor tracks (not shown).
  • a protective cap 11 is arranged on the outside of the base 7.1.
  • a throwing body 14 is arranged in the extension tube 7, the diameter of which essentially corresponds to the inside diameter of the extension tube 7. At its rear end, the throwing body 14 has an annular guide edge 16 which, when the throwing body is inserted, sits on the floor 7.1 and, as can be seen in FIG. 3, encloses an expansion chamber 15 arranged between the bottom 7.1 and the underside of the throwing body 14.
  • the extension tube 4 shows the extension tube inserted into the throwing cup with the throwing body inserted.
  • the retaining collar 8 is arranged on the extension tube 7 such that when the extension tube 7 is in the inserted state it protrudes from the launch tube 1 at both ends and the contact pins 17 of the throwing cup lie opposite the contact rings 9 of the extension tube and are in electrically conductive contact with them, so that The ignition current can be conducted to the propellant charge screw 12 via the contact pins 17 and the contact rings 9 as well as the conductor tracks (not shown) in order to ignite the propellant charge.
  • the space required for the expansion of the gases in the propellant charge is given by the expansion chamber 15 in the base of the projectile 14. This ensures that a 12% longer guide path is achieved and a more favorable effect of the gas pressure is generated.
