Definitions

  • the present invention relates to an electrical initiated ammunition body according to the preamble of the claim 1.
  • Ignition devices according to the preamble of claim 1 are notoriously known and are considered a compact unit assigned to the charge to be initiated.
  • the object of the present invention is therefore an ignition device to create a high shock resistance and withstands high accelerations. simultaneously should be the space available in an ammunition body be used and the total weight of the ignition device to the known (e.g. EP-A1-156,763; US -A- 5,269,223) can be reduced.
  • the ignition device is intended in particular for tandem shaped charges be suitable; the shock wave generated by the subpoena In any case the main charge should not be ignited influence, or the functionality of the second Do not interfere with the igniter.
  • the embodiment according to claim 2 enables optimal Utilization of the space in the usually rotationally symmetrical ammunition body and at the same time an increase in shock wave safety the device.
  • a distribution of the electronic components according to claim 3 reduces pulse transmission to the circuit board and dampens the effect through the sealing compound the shock waves.
  • a shock wave barrier according to claim 4 increases the mechanical Stability of the entire system.
  • a one-piece design of the barrier is particularly favorable according to claim 5, because the propagation of the pulse energy a distribution on the shell of the ammunition body experiences.
  • the safety and control device becomes elastic stored on the shock wave barrier, this is what it experiences an extensive decoupling from the impulse transmission what whose functional reliability is further increased, claim 6.
  • the arrangement according to claim 7 is particularly space-saving, without the advantages of spatial and functional separation of the system.
  • Claim 10 is particularly cheap.
  • 1 denotes an ammunition body that has a tail unit 2 on the rear and a drive 3 shot down from a tube - not shown here becomes.
  • the propellant charge in the tube is designated 23; the wing parts that straighten up after the launch of the tail unit 2, with 21.
  • Guided and centered the projectile 1 through a guide ring 20 which in itself known type is designed as a sealing lip.
  • the ammunition body 1 has a proximity detector (Proximity switch) serving double hood 4 on, which is reinforced by an insulation ring 5, between their a switching function, spaced apart a dome-shaped tip forms.
  • a proximity detector Proximity switch
  • the preload 6 is held and centered a central support 8, with a bell-shaped receiving cup 8th'.
  • a first security element 9 can be seen, that in its in-focus state a detonator (not shown) (detonator / squib) brings into operative connection with an ignition chain 24.
  • the security element 9 is axially fixed by a Screw cap 28, which in turn has a shock absorber 12, a potted electronic security element 13 and one with the housing 1 'of the ammunition body 1 connected shock wave barrier 14 is clamped.
  • the electronic security element 13 exercises in addition to the security function (e.g. according to STANAG 4187) also a control function off since it's setting delay times allows.
  • An electrical connection line 11, in the form of a flexible Bands is from the inner part of the double hood 4, in one Distance cone 10, from there partially on the surface of the housing 1 'to igniter connections 26 and 27 and to one Connection cable 22 out with a stationary - not shown here but known per se - supply and control unit is connected.
  • the shown distributively arranged ignition device carries the launch kinematics and that of a warhead in the target expected physical conditions and previously ensured the function of the tandem shaped charge unknown system security.
  • the arrangement according to the invention has a very positive effect in warheads with tandem shaped charges. It shows up in practice that when hitting a target Z, Fig. 2, the notorious known and expected switching function by the Double hood 4 is exercised that during the launch security elements 9 and 13 of the here summons VL as well as 18 and 19 the main cargo HL work in time or at the destination detonate sequentially.
  • the marching speed v of the ammunition 1 is represented by a known additional built into the tail unit 2 Propellant rate kept constant over the entire trajectory.
  • the electronic security elements 13 and 19 with their Time delay circuits are on annular circuit boards 30 built up, which is indicated in Fig. 2 by arrows are.
  • 3 is a circuit board 30 in Top view drawn on the active components at 31 and passive components 32 are designated.
  • the circuit board 30 is in accordance with FIG. 4 in a receiving ring 34 Polyvinyl chloride by means of a casting compound 35 from notoriously known polyurethane embedded; out of this is a flexible connection cable 33 led out.
  • the bore 36 present in the receiving ring 34 is dimensioned such that that the mechanical security element 13 can be pushed in, like the similar security elements 18 resp. 19 show.
  • the mechanical security elements 9 and 18 are as such known, a preferred embodiment with less Total mass is shown in Fig. 5.
  • a double mass lock not shown releases the rotor body 47 only when the predetermined one Minimum acceleration and duration when the Ammunition body 1 is reached.
  • the rotary motion of the rotor body 47 from the secured state to that shown in FIG. 5 Position is 270 °; here is the ignition energy fed via a spring pin when the through the electronic Security element 13 or 19 controlled conditions are fulfilled.
  • the arrangement of the ignition device will be that of tandem shaped charges feared simultaneous firings of both Charges prevented.
  • the can Ignition device be constructed from identical elements, i.e. the mechanical security elements 9 and 18 and the electronic elements 13 and 19 are interchangeable.
  • the concentric arrangement of the elements 18 and 19 is special space-saving and can be the same or similar Way to arbitrarily designed, even individual loads and Ammunition or pyrotechnic elements can be adjusted.
  • the device is particularly suitable in connection with tandem loads, the effects of which are coordinated are, as shown in the example of shaped charges has been.
  • the subject of the invention is also in Can be used with contactless proximity detectors, such as those that have a so-called triangulation sensor use with a laser diode or those those with inductive or with radar distance sensors work.
