Definitions

  • the invention relates to a device for non-detonative Removal of objects capable of detonation with own ignition system using an EFP charge that consists of a cylindrical shell with a bottom and a detonator, one Explosive charge and the charge on the detonator opposite, disc-like insert exists, which accelerates after the charge is ignited and is transformed into a projectile.
  • the invention further relates to a use of the aforementioned device.
  • EFP loads have already been proposed for clearing purposes Service. They consist of a cylindrical shell with a bottom and a detonator, an explosive charge and one covering the load on the opposite side, disc-like insert. After igniting the load the deposit is accelerated and at the same time becomes a projectile reshaped.
  • EFP charges US 4,982,676 A1
  • Such EFP charges are used usually itself as a weapon, in which the high Penetration effect of the projectile is used. Will you used to remove objects capable of detonation, this inevitably leads to the detonation of the object itself.
  • This method sets a very exact adjustment of the shaped charge beam and thus the constructive one Construction to the conditions of the object (Thickness, shell material, type and mass of the explosive etc.), on the one hand the creation of a shot channel and deflagration and pressure build-up in the firing channel to ensure without first the ignition system of the object responds.
  • This adjustment is extremely difficult and in many cases does not succeed, so that it does a detonation comes.
  • the procedure is also unsuitable if there is a risk that the object crossing the object Hollow charge jet exiting the object onto parts that must be protected from destruction. This enforces at least one orientation of the shaped charge, in which such Parts of the shaped charge are not hit.
  • the invention has for its object a device for the non-detonative elimination of detonable Propose objects based on an EFP load.
  • This object is achieved in that the EFP load a barrier disc at a distance from its insert which has the projectile hitting it decelerates and forms an effect on the object Splinter cloud disassembled.
  • the invention proceeds from a substantially conventional one EFP charge off, but at a distance from the insert a barrier disc is arranged, which is used for a fan of energy provides.
  • a barrier disc is arranged, which is used for a fan of energy provides.
  • the barrier disc is at least in the puncture area and at the same time a large part of the projectile Splinters disassembled and the impulse energy of the projectile gave up the splinters.
  • a splinter cloud is created, the at a reduced speed compared to the projectile speed but with a wide area effect on the object incident.
  • the fragments penetrate the shell and disassemble the object into fragments that can no longer be detonated. This process takes place in just a few microseconds is less detonative than the response time of conventional ignition systems Objects.
  • Another parameter, in particular the impact speed the splinter cloud at a given exit speed is the distance between the EFP and the object, which is preferably adjustable. With this Setting can also be between the medium (air, water) the EFP load and the property are taken into account.
  • the envelope the EFP load has a cylindrical one in the area of the insert Has extension whose inner diameter is matched to the outer diameter of the insert and the closed at the opposite end by the barrier disc is.
  • the insert is preferably seated in one Impedance ring at the transition between the shell and the cylindrical Extension is arranged.
  • the barrier disc is preferably made of metal, in particular made of steel or a non-ferrous alloy. As beneficial manganese alloys have been proven.
  • EFP charge preferably positioned near the object and with its axis aligned with the object.
  • the EFP charge with its axis under one Align angle to the support of the object is preferably less than 45 °.
  • the device according to the invention is in particular for non-detonative disassembly of weapons, terrorist Explosive charges and mines, especially underwater mines, but most of all from mines on ship hulls suitable.
  • the invention is based on exemplary embodiments and test results are described.
  • the EFP charge 1 shows a schematic longitudinal section of an EFP charge 1 with a barrier disc 2.
  • the EFP charge 1 exists from a sleeve 3 made of plastic with a bottom that receives a detonator 4.
  • an impedance ring 5 used in the shell is at a distance from Igniter 4 an impedance ring 5 used.
  • the space between Bottom and impedance ring 5 is filled with explosive 6, the is covered by an insert 7, which in the embodiment shown is arched to explosives 6.
  • the Insert 7 sits in the impedance ring 5.
  • the casing 3 Plastic has a cylindrical extension 8, the is closed at its end by the barrier disc 2.
  • the space filled with the explosives 6 can be on the back of a cylindrical or conical shell 9, preferably limited to plastic, metal, glass or ceramic.
  • the insert was an armco liner.
  • the mass of the impedance ring m R 50g
  • the explosive mass m EX 230g.
  • the distance L between the impedance ring 5 and the barrier disk 2 was approximately 200 mm.
  • Barrier panes made of plastic, metals and in particular those made of the alloy 9 SMnPb 28 with different thicknesses were used.
  • FIG. 2 to 5 are X-rays immediately after The impact of the projectile on the barrier disk, at time t after the explosive is detonated were recorded. The time is on the left of the pictures specified.
  • a Barrier pane with 5mm thickness made of PVC On the right The end of the envelope 3 can be seen at the edge of the figures.
  • Fig. 2.1 shows the projectile formed from the armco liner 10, the barrier pane 2 made of PVC already largely has penetrated.
  • Fig.2.2 shows that the barrier disc 2 largely into a cloud 11 from fragments has been disassembled while projectile 10 is in shape essentially maintained and preceded the cloud.
  • Fig. 3.1 gives the conditions for the same experimental setup for a 5mm thick barrier disc made of 9 SMnPb 28 again.
  • Fig.3.1 shows the situation immediately after passing through of the projectile through the barrier disc 2 that its scope has largely been preserved.
  • a comparison of Fig.3.2 and 3.3 shows that the Splinter cloud 13 remains behind the remaining projectile 12.
  • Fig. 4.1 Similar relationships can be seen from Fig. 4.1 to 4.3.
  • a barrier disc was made from the same alloy, but with a thickness of 10mm.
  • Fig. 5 shows that with a barrier disc 15mm thick, the remaining projectile is even smaller and the fragment cloud is more compact.
  • the free flight distance of the projectile in the shell corresponds to the remaining distance between the barrier disc and the insert.
  • the residual projectile 12 remains extremely behind the splinter cloud 13.
  • FIG. 10 shows a schematic section of the experimental arrangement.
  • a flameproof slipcase 15 is filled with water.
  • EFP load 1 with barrier disc 2 used.
  • Within the cassette 15 is opposite at an angle of 30 ° the axis of the EFP cargo 1 on the hull of the hull simulating steel sheet 16 arranged on the one Mine housing 17 is attached, optionally with inert material or explosives.
  • FIG. 11 shows the result of an experiment with an inert filling the steel shell of the mine, on a 6mm steel sheet was mounted.
  • Fig. 11 shows the complete dismantling of the mine housing and its filling.
  • Fig. 12 shows an experiment with the same Parameters as in Fig.11, but the mine housing was filled with 316g TNT with PVC binder.
  • Fig. 12 also shows that mine in full dissolution including the explosives filling.
