Definitions
- the invention relates to a warhead according to the preamble of claim 1.
- Such a warhead is known from DE-OS 22 42 930.
- the known warhead comprises a warhead housing for receiving a shaped charge as well as an impact detonator connected to the warhead housing and comprising a firing pin which is movably mounted in the axial direction.
- the warhead is transported in large numbers by a missile or carrier projectile over a target area and is ejected there.
- the firing pin accelerates due to its inertia and ignites a detonator, which in turn detonates the charge of the warhead, preferably a shaped charge.
- the invention has for its object to expand the known warhead by a self-defeat option.
- the invention has the advantage that the own troop ge any potentially dangerous unexploded ordnance can be largely avoided, since the self-disassembly device activates the warhead of the warhead even in the event of a failure of the impact detonator and thus renders it harmless. In addition, however, this increases the reliability of the warhead, since even if the impact detonator fails, the self-destruct device can still detonate the warfare and thus make the warhead effective.
- Fig.1 A side view of a warhead of the generic type in a schematic representation
- Fig.2 an enlarged sectional view of the detonator part of the warhead.
- the warhead 10 comprises a warhead housing 11 for receiving a war charge, preferably a shaped charge.
- a warhead housing 11 for receiving a war charge, preferably a shaped charge.
- a rear-mounted detonator housing 12 is connected, which contains an impact detonator.
- a swirl brake 13 is attached to the detonator housing and, after the warhead 10 has been ejected from the spin-stabilized carrier projectile, reduces the number of swirls and improves the flight stability of the warhead 10 when it descends to the target area.
- the impact detonator (FIG. 2) comprises an ignition needle 1, which is fixed in the secured position, but is arranged to be axially movable in the unlocked state and cooperates with a detonator 8, which if necessary by means of a transmission charge 9 detonates the combat charge 10.
- the firing needle 1 is hollow and has a tapping primer 1 a, a pyrotechnic delay line 1 b, and an output primer 1 c in its recess in the following row, starting at the rear.
- a needle 7, which interacts with the tapping primer 1 a, is also arranged in a fixed position in the igniter housing 12.
- the mode of operation of the self-tapper and ignition device is as follows:
- the starting point is the safeguard shown in FIG. 2, in which the firing needle 1 is fixed by safety means 5 which can be removed in the radial direction and consequently cannot move in the axial direction even when subjected to impact loads.
- the tip 1 b of the ignition needle 1 lies in a blind bore of the detonator carrier 8 c, which is acted upon by a compression spring 8 d and can be extended in the radial direction, and thereby prevents its evasion in the radial direction.
- the compression spring 6 acting in the axial direction pushes the ignition needle 1 backwards, the needle 7 fixed to the housing activating the tapping primer 1 a, which in turn activates the pyrotechnic delay line 1 b.
- the tip 1 d has slipped out of the blind bore 8 b and has released the detonator carrier 8 c, which now swings spring-loaded in the radial direction in such a way that the detonator 8 comes to rest under the tip 1 d of the ignition needle 1 and is flush with the transfer charge 9 and thus produces a pyrotechnic ignition chain for combat charge 10.
- the tip 1 d of the firing needle 1 is in the ready-to-fire position above the detonator 8 until the warhead hits the target.
- the firing needle 1 due to its inertia, accelerates against the force of the compression spring 6 in the axial direction and pricks the detonator 8, which in turn mediates the transfer charge 9 the combat charge 10 for deto nation brings.
- the self-disassembly device also acts.
- the pyrotechnic delay line 1b has been blown to the output primer 1c and activates it, causing a flame front to pass through the holes 1e in the area of the needle 1d and to act upon the erroneously not activated detonator 8 with such a high temperature that it nevertheless does so still comes into operation.
- the starting primer 1 c is advantageously designed to be detonative, as a result of which even greater security for activating the combat charge 10 a can be achieved.
- the burning time of the pyrotechnic delay line 1 b was dimensioned to be about 8-10 seconds.
- the pyrotechnic delay line consisted of a known pyrotechnic composition with a diameter of about 3 mm and an envelope with a thickness of about 1.5 mm; the entire length of the pyrotechnic delay line was approximately 18 mm.
