Definitions

  • the invention relates to a detonator for swirl projectiles according to the preamble of patent claim 1.
  • Such a detonator is known from DE-OS 23 36 880.
  • all the disassembly balls are already in their working positions from the outset, so that the ball carrier allows the rotor to swivel into the ignition position immediately after leaving the muzzle.
  • the present invention has for its object to provide a detonator for swirl projectiles with a rotor that meets increased safety requirements, namely that the rotor carrying the detonator should remain in the safety until a pre-pipe safety time has elapsed after leaving the pipe mouth within the detonator must not be armed and precludes an unintentional ignition.
  • the rotor should be locked by two separate, independent locks, which are unlocked if possible by different physical variables acting on the projectile, whereby one of these locks can already be unlocked during the launch, while the second lock can only be unlocked by another bullet or trajectory-specific force after the end of the downtube or safety phase allows the rotor to pivot into the ignition position.
  • Increased safety requirements of the detonator also mean measures which increase the sensitivity and which ultimately guarantee the detonator's self-dismantling, provided that the detonator does not respond to a target.
  • FIG. 1 and Figure 6 show in longitudinal sections two embodiments of the detonator according to the invention for swirl projectiles.
  • the igniter comprises in a cylinder body 22, 622 consisting of a plurality of screwed parts, an actuating device consisting of the disassembly spring 13, 613, the ball carrier 11, 611 and the needle carrier 16, 616, a rotor 20, 620 containing a pyrotechnic ignition charge 23, 623 and in rear part a transfer charge 24, 624.
  • the disassembly spring 13, 613 which is supported on the cylinder body 22, 622, presses the ball carrier 11, 611 in the rear direction of the cylinder body 22, 622 such that the needle carrier 16 in FIG.
  • this fuse consists of a ground pin 18, 618, which, loaded by a compression spring 19, 619, is slidably mounted in a bore 21, 621 running eccentrically parallel to the longitudinal axis.
  • the front part of the ground pin 18, 618 engages in a recess in the rotor 20, 620 and, in cooperation with the needle carrier 16, 616, prevents the actuating device 11, 13, 16, 611, 613, 616 Rotation of the rotor 20, 620 in its operative position.
  • the two safety systems blocking the rotor 20, 620 engage diametrically lying in the rotor 20, 620 in such a way that the latter cannot move out of its securing, in particular also due to shock and vibration loads which can occur during transport and handling of the projectile .
  • disassembly balls 6, 9, 10 are provided in FIG. 1, which are arranged in bores 8 of the ball support 11 and are supported on the ball bevel 12 of the ball support 17 while in FIG. 6, at most two disassembly balls 606 are provided, which are arranged on the base of bores 607, secured by locking balls 604, 605.
  • the rotor 20, 620 is released from its securing, as will be explained in detail below, so that it can pivot into its operative position.
  • two disassembly balls 9, 10 are already from the beginning, i.e. also arranged in the stored state of the igniter in its working position in the bores 8 of the ball carrier 11. These balls alone would not be sufficient to be able to lift the ball carrier 11, together with the needle carrier 16, under the influence of rotation against the pressure of the disassembly spring 13 from the contact surface on the rotor 20. For this purpose, a further disassembly ball 6 is required.
  • the third disassembly ball 6 necessary for releasing the detonator is arranged to ensure the detonator at the bottom of a bore 7, which, starting from the rear part of the ball carrier 11, is arranged obliquely to the longitudinal axis of the ball carrier 11 and opens into the bore 8, which Splitter ball 6 during its working position, ie in the operative position of the actuating device 11, 13, 16.
  • the bore 7 is expediently designed as a through bore and then closed with the aid of the needle carrier 16.
  • Another exemplary embodiment of the invention provides that only one disassembly ball 606 is securely mounted at the bottom of the bore 607 and only moves into the working position on the ball bevel 612 under the influence of a swirl. This results in a particularly simple construction of the igniter.
  • the disassembly balls 6, 606 are secured by locking means which are arranged in a bore 15, 615 arranged in the ball carrier 11, 611.
  • a locking pin 5 'or locking balls 4, 5, 604, 605 are expediently used as locking means.
  • the bore 15, 615 appropriately cuts the bore 7, 607 in such a way that the mouth cross section of the bore 15, 615 is smaller than the diameter of the locking means 4, 5, 5 ', 604, 605, so that it does not completely enter the bore 7 , 607 can reach.
  • the bore 15, 615 is closed by a winding tape securing device which consists of the winding tape 1, 601 and the winding carriers 2, 3, 602, 603.
  • this winding tape safety device prevents the locking means 4, 5, 5 ', 604, 605 from escaping in the radial direction from the bore 15, 615 and thus the release of the disassembly ball 6, 606.
  • the use of two winding carriers 2, 3 , 602, 603 offers the advantage of reliable guidance of the winding tape 1, 601.
  • the spherical slant carrier 17 is expediently designed as a circular ring, the inner edge of which is chamfered conically to form the spherical slant 12.
  • the spherical slant carrier 17 is advantageously designed so that it is easily replaceable on a step 25 in the fuse body 22. On the one hand, this enables a relatively simple processing of the spherical bevel to be observed very precisely and, on the other hand, an easy exchange of the spherical bevel carrier, for example in order to bring about a different disassembly characteristic of the detonator by replacing a spherical bevel carrier 17 with a differently designed spherical bevel 12.
  • the igniter is required to disassemble itself if it does not respond to a target. This is caused by the fact that, when the detonator rotates slowly, the disassembly balls 606 on the bevels 612 move radially inward and thus allow the spring-loaded needle carrier 616 to move in the direction of the detonator 623 of the rotor 620 in focus.
  • the winding tape carrier 603 closer to the head part of the igniter has a smaller diameter than the winding tape carrier 602 facing the rear part of the igniter.
  • a cylindrical pin 629 is slidably mounted in a bore 628 in the head part of the igniter body and is arranged in such a way that it is coaxially surrounded by the spring 613. This pin 629 supports the movement of the needle carrier 616 in the direction of the detonator 623 via the ball carrier 611.
  • FIGS. 2, 3, 5 and 7, Details of the blocking of the disassembly ball 6 by the blocking means 4, 5, 5 ', 604, 605 arranged in the bore 15 can be seen in the further FIGS. 2, 3, 5 and 7, which can be understood from themselves without a detailed description.
  • FIG. 4 which represents a section along the line C - D of FIG. 1 and which illustrates the arrangement of the disassembly balls 9, 10 in the bores 8 in the ball carrier 11, does not require any further description either.
  • these disassembly balls 606 then first run in the bore 607 in the direction of the detonator tip until they enter the bores 608 which were not occupied until then. Together with the further disassembly balls 9, 10 already in the working position, that is to say in the bores 8, the disassembly ball 6 according to FIG. 1 or the disassembly balls 606 according to FIG.
  • the detonator comes into operation as soon as there is an impact on the projectile or as soon as the restoring force of the disassembly spring 13, 613 outweighs the centrifugal force transmitted to the ball carrier 11, 611 by means of the disintegration balls 6, 9, 10, 606.
  • the design of the detonator according to the invention offers the particular advantage that the rotor 20 is locked in its securing by two independently acting securing systems and that, in addition, the front pipe safety which meets all requirements is achieved by the separate blocking of the splitting ball 6.
