Definitions

  • the invention relates to a projectile fuze according to the preamble of claim 1.
  • Such a projectile fuse is used for example as a mortar fuse.
  • Realized is such electrical safety overflight in such a way that by means of an external programmer, the time of flight of the projectile is programmed into the detonator electronics ie fed. After the launch of the projectile, a timer / counter is started, which counts up to the programmed flight time minus a fixed time value and then charges an electrical ignition circuit of the ignition electronics. This charging of the ignition circuit is in the msec range, so that the projectile fuze is ready to fire in time in the specified target.
  • the securing device is designed such that after a very short in relation to the total trajectory very short time period, the mechanical interruption of the ignition chain is canceled, i. the so-called pre-pipe safety is comparatively small.
  • the invention is in the knowledge of these circumstances, the task of creating a projectile fuse of the type mentioned, which has a programmable electrical and mechanical safety overflight and a comparatively large Vorrohrpiping.
  • the safety device is blocked by a pyrotechnic force element as long as possible, i. held in the safe until the programmed or, if necessary, also manually set flight time - minus a fixed time value (speed safety) is reached. If the set flight time minus the set time value is reached, the ignition circuit for the force element is charged and the safety device is unlocked by igniting the force element. The fuse then goes into focus, i. the ignition chain is broken and the ignition chain is then inline. Now, the actual ignition circuit of the projectile fuze according to the invention is charged, so that the detonator in the intended destination is ready in time to fire.
  • FIG. 1 illustrates a trajectory 10 of a projectile having a conventional projectile fuse, wherein the arrow V designates the pre-pipe safety, the arrow Ü the overflight safety, and the arrow T the time of flight or target distance. With h the ignition height of the projectile fuze is designated.
  • FIG. 2 illustrates, in a representation similar to FIG. 1, the trajectory 10 of a projectile having a projectile fuse according to the invention, the arrow V once again designating the mechanical pre-pipe safety and the arrow T designating the time of flight or target distance.
  • H in Figure 2 denotes the ignition height of the projectile fuze.
  • the arrow Ü also indicates the safety against overflight in FIG. 2, which, however, is an electrical / mechanical overflight safety, the point S designating the point of focus of the safety device of the projectile fuze.
  • FIG. 3 shows a longitudinal section of an embodiment of the projectile fuze 12 according to the invention, which has a pyrotechnic force element 14 which is interconnected with ignition electronics and blocks a safety device 16 until the time of flight T minus a predetermined time value ⁇ t (see FIG. 2). is reached. Once that is the case, an ignition circuit of the projectile fuze 12 is electrically charged and the safety device 16 is unlocked by igniting the pyrotechnic force element 14 in the armed position.
  • FIG. 3 shows the securing of the securing device.
  • the securing device 16 has a rotor 18 with a firing pin 20 and with a puncture detonator 22.
  • the firing pin 20 and the piercing detonator 22 are aligned with each other axially and are spaced from each other.
  • the projectile fuze 12 has an electric detonator 24, which is interconnected with the ignition electronics.
  • the projectile fuze 12 also has an booster charge 26 associated with the electric detonator 24.
  • the rotor 18 is provided between the electric detonator 24 and the booster charge 26.
  • FIG. 4 illustrates, in a longitudinal section similar to FIG. 3, another embodiment of the projectile fuse 12 according to the invention, wherein the same details are denoted by the same reference numerals as in FIG. 3, so that it is not necessary to describe all these details in connection with FIG.
