Definitions

  • the present invention relates to a structure a projectile according to the preamble of claim 1.
  • tandem shaped charges both the impact shock, as well as the ignition the summons the training of a high-energy Can prevent beam.
  • It is therefore an object of the invention is a shock-absorbing To create structure for a projectile, which its system security increases and in particular an early initiation prevents the main charge.
  • the charges mentioned in the claim are usually shaped charges and thus form a tandem shaped charge.
  • shaped charges and combinations thereof conceivable such as a front projectile charge and a rear conventional charge (inter alia to EP-B1-0 955 517.
  • multiple warheads can be removed after realize the same basic principle.
  • the subject invention is based on the knowledge that the projectile shell in the area of its front (first) charge can be thin-walled when on exterior massive structures is omitted, which redirect the gas shock of the first charge. Also, the spacer tube is thin-walled and prevented through a continuous enlargement of his Diameter direct transmission of the impact shock to the center of the second charge. The one at the finish high internal pressure causes the spacer tube to burst, the individual Fragments fly away in the radial direction without the to obstruct the second charge.
  • the second charge reverses to the first charge at least a factor of 2 greater caliber; accordingly also increases the diameter of the spacer tube.
  • the Length of the spacer tube, i. the distance between the two Charges are at least twice the second Caliber.
  • annular flanges act as Shock barriers and reduce mechanical stress ignition systems and charges.
  • Acceleration measurements on tandem-shaped projectile bullets having a structure designed according to the features of the claim show relatively small g-values (9.81 ms -2 ) at the location of the main charge. Likewise, the vibrations which disturb the effective jet are minimal. This is proven in fired projectiles by the high drilling performance of the charge jet in the target.
  • the division of the spacer tube according to claim 2 has manufacturing technology and kinematic advantages.
  • the embodiment of claim 3 is very space efficient and ideally takes the impact pulse for commissioning the igniter on.
  • a metal calotte can be used for the impact and the ignition of the summons resulting shock waves redirect to the housing shell; Claim 4.
  • a direct placement of the calotte according to the claim 6 reduces the free path of the ram, increases but the effect deflecting the shockwaves.
  • a lateral storage of the damping material in one elastic ring reduces the transmission of vibration on the following structure.
  • the embodiment of claim 9 increases the shock absorption and reduces the transmission of vibrations the sensitive second charge.
  • Damping materials and in particular damping rings easily deformable material has proven itself such as commercial aluminum foam. Especially advantageous But is a material made of a plastic with embedded microballoons, as in CH -A5-674077 described. Cf. claim 10.- Such materials are now commercially available and are the detonation wave deflection used in shaped charges. Analogous active materials based on wood (cellulose) are also known.
  • Fig. 1 The self-propelled projectile with a tandem shaped charge
  • Fig. 1 is axially symmetrical to a designated A.
  • a head 1 consists of a tip 2 with inserted elastic rings 3 and points to reason Its slim shape gives good aerodynamic properties on.
  • the top 2 set back is a first hollow charge, consisting from a lining 4 and a high performance explosive, 5. Both form a summons and are arranged in a cylindrical portion 7a, which Rear side is delimited by a flange 10a.
  • This flange 10a is an autonomous ignition device. 6 used, which projects into a part of a spacer tube 7b.
  • the part 7b is over a fit of a joint 7d connected to a further part 7b 'of the spacer tube.
  • the part 7b ' has front side a flange 10b with an open passage 13 through a support dome 11 'is covered.
  • a damping material 9 ' glued.
  • a relatively large one Cavity 8 which is a possible gas shock of the summons 4,5 and its kinetic energy in Deformation and fracture energy on the spacer tube 7b, 7b ' transfers.
  • Another joint 12 connects the spacer tube 7b ', overlapping, with another cylindrical portion 7c the projectile casing 7a-7c.
  • the main charge 14,15 with their lining 14 and the explosive 15th
  • This hollow charge 14,15 is supported on a rear part 21, which in an adapter 16 another autonomous Ignition system 17 receives and from the drive nozzles 18 of a protrude solid propulsion 19 known.
  • an adapter 16 another autonomous Ignition system 17 receives and from the drive nozzles 18 of a protrude solid propulsion 19 known.
  • a tail 20 At the end hinged wings of a tail 20 are visible.
  • Fig. 2 In the enlarged sectional view Fig. 2 can be seen above the cylindrical portion of the projectile casing 7a the screw-in point for the tip 2 indicated.
  • the lining 4 ends in a threaded connection 41.
  • the explosive 5 is positively on the massive flange 10a, which is formed integrally with the part 7a.
  • a Zündvertärker 42 in a centering pin 44th used, which in turn receives a damping ring 43, where the not shown here ignition system 6 is applied.
  • the cylindrical part 7a ends fitting in the cavity of the spacer tube 7b.
  • FIG. 3 shows the lower shock barrier, the protrudes into the interior of the spacer tube 7b.
  • the joint 7d with a protruding Ring of the lower part 7b ' is suitable and the Part 7b is supported there.
  • a likewise massive Flange ring 10b are a damping ring 9 and inserted therein a dome 11 glued on.
  • FIG. 3 shows symbolically represented by arrows, which Front of a shock wave, derived from the dome 9 becomes.
  • Front of a shock wave derived from the dome 9 becomes.
  • FIG. 4 An analogous solution can be seen in FIG. 4: Here it is the shock wave first on damping material 9 'and then only on a centered in the bore 13 carrier dome 11 '. In addition, the damping material 9 'edge in one soft damping ring 45 stored.
  • FIG. 5 Details of the assembly of the main charge are shown in FIG. 5 to take:
  • the liner 14 is positively on the molded Charge 15 and has one at its largest diameter Passing ring 14 a, by a damping sleeve 46 and a Threaded sleeve 47 is loaded.
  • the threaded sleeve 47 is in an internal thread 48 of the cylindrical projectile casing 7c screwed.
  • the typical marching speed of the projectile is below of 300 m / s.
  • the caliber of the summons is in the embodiment 32 mm; that of the main charge 112 mm.
