Definitions

  • the invention relates to a warhead according to the preamble of claim 1.
  • Warheads of the type mentioned at the outset are known from the magazine "Internationale Wehrrevue" No. 8/84, page 1056. These warheads contain an active charge, for example a shaped charge or a projectile-forming charge, the effectiveness of which is severely impaired by excessive swirl values. After a warhead of this type has been ejected, the twist communicated to it by the spin-stabilized cargo floor must therefore be reduced to sufficiently low values.
  • so-called swirl brakes are known from the same reference in the form of sheet metal strips arranged uniformly distributed over the circumference of the warhead, which spread out after the warhead has been ejected, thereby increasing the air resistance and thus reducing the number of revolutions of the warhead. These swirl brakes are an additional component that increases the cost of manufacturing the warhead and, at the same time, takes up space in the limited volume of the warhead, which is urgently needed to accommodate a sufficiently effective payload.
  • the invention has for its object to improve a warhead of the type mentioned in such a way that effective as a swirl brake, additional components of the warhead can be dispensed with. In this way, the production is simplified and cheaper and the payload volume is increased.
  • FIG. 2 shows a schematic representation of a warhead 10 which, after being ejected from a cargo floor, not shown, descends from a parachute 11 to a target area.
  • the parachute 11 as indicated in FIG. 3, was arranged in the rear part 12a of the housing 12 of the warhead 10.
  • the rear part 12 a of the housing 12 forms a recess for this purpose, which receives and protects the parachute 11 during the transport of the warhead 10.
  • the warheads transporting the warheads 10 are mostly spin-stabilized, so that after the warhead 10 has been ejected and expediently before the parachute 11 is deployed, the swirl of the warhead 10, which has been communicated in the cargo floor, to the active part of the warhead 10 tolerable values must be reduced.
  • This is particularly advantageous according to the invention is sufficient that an annular region 12 a of the housing 12 is divided into segments 13 a, 13 b, 13 c, 13 d, which are pivotally mounted eccentrically on axes 14 a, 14 b, 14 c, 14 d arranged in the housing 12 ( Fig. 1).
  • the segments 13 a, b, c, d initially form part of the cylindrical landing of the housing 12 of the warhead 10. After the warhead 10 has been ejected, however, the segments 13 a, b, c, d are pivoted outward in such a way that they overlap protrude the diameter of the warhead 10. They are exposed to the air flow and offer such a high resistance that the number of revolutions of the warhead 10 noticeably decreases in a very short time while it continues to descend towards the target area. When ejected from swirl-stabilized cargo floors, the segments are swung out by centrifugal force, so that no additional force elements are necessary.
  • the segments 13 a, b, c, d which were initially effective as a housing component and protect the parachute 11, are now used as a swirl brake. Characterized in that now after the pivoting of the segments 13 a, b, c, d, the recess receiving the parachute 11 is freely accessible to the air flow, the safe deployment of the parachute 11 is also promoted. Since already existing housing parts can now be used as swirl brakes, a dead load component can be saved and additional space can be gained for the payload.
  • FIGS. 4 and 5 again shows a plan view of the warhead 10, but for reasons of simplification only one segment 13a is now shown, which has already given up its housing function and is pivoted outwards about the axis 14a. 1 and 3, the axis 14 a and of course the axes 14 b, c, d, which are not expressly shown, are arranged at an angle with respect to the longitudinal axis 50 of the warhead 10 in such a way that they enclose an angle ⁇ with the latter , This has the consequence that the lateral boundary surfaces of the segments 13 a, b, c, d are adjusted with respect to the direction of fall of the warhead 10 (corresponding to arrow 30 in Fig.
  • the adjustment of the segments can be used to apply a defined residual swirl. Force elements are then to be provided for pivoting out the segments.
