Definitions

  • the invention relates to a safety device for an igniter of a warhead according to the preamble of claim 1.
  • a safety device for detonators of swirl-less or low-swirl projectiles is known, which has a rotor with edge recesses into which a two-armed pawl under the force of a spring ensures the Igniter intervenes.
  • the pawl which can be pivoted about an axis of rotation, is also connected to a recoil pin system and, together with the return spring and the recoil pin system, additionally forms a safety device in the event of incorrect assembly.
  • these mechanical means are not intended to prevent the rotor from moving from its securing to the armed position when the ignition device is installed.
  • the built-in securing element has the effect that in its one position (blocking position) the assignment of the ignition device to the ammunition is prevented and that in its other position (installation position) this assignment is permitted. Due to the coupling point between the rotor and the built-in securing element, the rotor, which is in the armed position, blocks the installed securing element in the blocking position. In securing the rotor, the built-in securing element is released for the transition to the installed position. With this safety device it is forcibly achieved that an ignition device with the rotor in focus cannot be installed in the ammunition. The ignition device can only be attached to a warhead when the rotor is in the safe position.
  • the built-in safety link must be operated manually. If this securing element is blocked, the rotor must first be placed in the securing position.
  • An ignition device has a carrier base (1).
  • a rotor (3) rotatable about an axis (2) is mounted on this.
  • the rotor (3) has a bore (4).
  • the rotor (3) is secured with known securing means. When the securing means are released, the rotor (3) swivels in the direction of the arrow (P) (see Figure 2) until the bore (4) is in line with the ignition chain of the ignition device.
  • a built-in securing element (5) formed by a pin is arranged on the carrier base (1).
  • the built-in securing element (5) is guided on the one hand on a bushing (6) screwed into the support base (1) and on the other hand on a bearing plate (7) which is connected to the support base (1) by a bolt (8).
  • the built-in securing element (5) can be moved parallel to the axis (2). It has a locking extension (9) and a collar (10). A compression spring (11) presses the built-in securing element (5) so that its locking extension (9) projects beyond the support base (1) (FIG. 1).
  • a part-circular recess (12) is provided on the outer circumference of the rotor (3). This merges into an annular groove (13) extending on the circumference of the rotor (3).
  • the recess (12) and the annular groove (13) of the rotor (3) on the one hand and the collar (10) of the built-in securing element (5) on the other hand form a coupling point between these two parts.
  • the collar (10) lies below the recess (12). If the rotor (3) is secure, its recess (12) is aligned with the collar (10).
  • the ignition device When the ignition device is installed in a warhead, its support base (1) is placed on a corresponding surface of the warhead.
  • the installation securing element (5) is pushed into the ignition device against the force of the spring (11) via the locking extension (9).
  • the collar (10) slides into the recess (12).
  • the locking extension (9) therefore does not hinder the installation of the ignition device.
  • the collar (10) lies at the level of the annular groove (13). If the rotor (3) is unlocked later, then it pivots. The federal government (10) hampers this not because the ring groove (13) moves freely with respect to the collar (10).
  • the blocking extension (9) does not move back when the carrier base (1) is placed on the corresponding surface of the warhead. Because the collar (10) then strikes the edge (14) of the rotor (3). Installation of the ignition device is therefore not possible.
