Definitions

  • the invention relates to a fuse for a pyrotechnic impact detonator a ballistic explosive projectile according to the preamble of claim 1.
  • the object of the invention is to increase the functional reliability of the ball fuse.
  • the greater functional reliability of the ball lock is due to that on the ball attacking spring element in front.
  • the spring element ensures in a simple manner ensuring that the ball is seated back in the direction of the floor. in this connection the ball seals the circumference of the central ignition channel.
  • fumes that may pass over the side of the ball stopped by the spring element or made harmless as far as that there is no ignition of the booster charge arranged downstream comes. Any fumes are ignited by the overleaf Spring element reduced several times and partly deflected in the centripetal direction, where they reduce or cancel each other out in terms of their energy.
  • a ballistic projectile 1 with a caliber of 40 mm consists of a projectile body 10 with annular groove 11 for a propellant charge sleeve, not shown, one piece Threaded ring 12, a guide ring 6, a ground screw 2, a cavity 13 with explosive charge 60, a valve body 65 and a hood 24.
  • valve body 65 and the hood 24 are connected via threaded connections 66, 67 screwed to the threaded ring 12.
  • an ignition charge 28 Located in the cavity 26 between the valve body 65 and the projectile hood 24 there is an ignition charge 28 consisting of an impact sensitive secondary explosive.
  • the valve body 65 lies with a collar 68 both on an end face 69 of the Threaded ring 12 and with a collar 70 on an annular surface 71 of the projectile hood 24 on.
  • the collar 68 protects the armor penetrable threaded ring 12 the explosive effect of the primer 28. Contributes to armor penetration also the step section 15 of the projectile body 10 at.
  • a transition 9 from the cylindrical inner wall 16 to the cone 17 of the projectile body 10 forms a predetermined breaking point, which is indicated as a wavy line 8.
  • at Detonation of the explosive charge 60 tears the projectile body 10 at the predetermined breaking point 8 and accelerates the step section 15 with the threaded ring 15 as one piece Part for the purpose of armor penetration.
  • a pin 30 of the valve body 65 has lateral ignition channels 41 and a two-stage Central bore 72.
  • the central bore 72 is divided into a ball guide 42 with ball 43, a flanged board 44, a helical compression spring 73 and in a bore 77.
  • the ball 43 is made of brass and seals in particular in a section 74 the central bore 72 from the circumference by the circumference of the ball 43 with little Play in the ball guide 42 is stored.
  • the ball 43 can also be from another Material such as steel or plastic.
  • the helical compression spring 73 is light between a shoulder 75 and the ball 43 biased. In the usual way, it has a central channel 76.
  • the diameter the central channel 76 corresponds approximately to the diameter of the bore 77 the central bore 72.
  • a conical in a conical recess 80 Charge 29 consisting of a secondary explosive, arranged.
  • This conical charge 29 serves as a booster charge.
  • the conical charge 29 lies with its large base 31 on the explosive charge 60. With that, the Charge 29 in the sense of a pointed cone charge has a large impulse effect.
  • the cavity 13 of the projectile body 10 is conical on the ogive side Section 14 provided. Accordingly, the explosive charge 60 lies with its conical Section 63 on the conical charge 29.
  • the conical section 63 has a free end face 62 that covers almost the entire area, ie almost 100% of the Base 31 of the cargo 29 touched.
  • the floor 1 is after completion of the ballistic Flight route as a dud, which can be cleared easily.
  • Dangerous ignition means are neither included in the ignited charge 28 nor Ignition charge 28 not ignited.
  • the priming charge 28 detonates at the same time armor penetration occurs.
  • the threaded ring 12 with the step section 15 perform the penetration work, so that the detonation of the projectile 1 is done inside the target.
