Definitions

  • the invention relates to a submunition body according to the preamble of patent claim 1.
  • a generic ammunition body is known for example from DE-A-34 28 051.
  • Submunitions with a target detection device are preferably used to combat ground-based armored targets from above.
  • a target area there are usually several submunitions inside a container, for example in a rocket or in the carrier shell of an artillery projectile, and can be ejected from it above the target area at a predeterminable height. They then sink individually and rotating about their respective central longitudinal axis and down on a device that reduces the falling speed and the speed.
  • the target detection device is activated in such a way that a signal which is characteristic of this target can be recorded when approaching a target.
  • DE-A-34 28 051 describes various mechanisms for an antenna of a target detection device from the inside of a submunition body to fold into a working position outside the submunition and to lock the antenna in this position.
  • the mechanisms described have in common that they require an additional energy source carried in the submunition body to initiate and carry out the folding movement of the antenna.
  • a desired gas pressure is set in a gas pressure slide and acts on a piston system.
  • the resulting movement of a piston rod is converted into a folding movement of the antenna by various mechanical means.
  • the locking of the antenna folded into the working position depends on the end position of the piston rod.
  • the extended antenna is held in its working position by a spring-loaded bolt.
  • this counterforce is produced by the pressure force of the propellant charge gases on the piston.
  • a precise locking of the antenna can only be guaranteed if the pressure of the propellant gases can be kept constant. However, this is practically not possible.
  • the type of locking of the antenna by means of a spring-loaded locking pin which is described in another exemplary embodiment, is also problematic, since fatigue of the spring of the locking pin, which is tensioned during storage, cannot be ruled out in the event of long-term storage of the ammunition body.
  • the invention has for its object to provide a generic submunition body, in which the pivoting of the reflector without additional energy source and its reliable locking in the working position is made possible in a simple manner and free of elements prone to fatigue.
  • FIG. 1 shows individual parts of a first submunition body in their position with respect to the central longitudinal axis 12 of the submunition body.
  • the submunition body has an active body 57 facing the target, which is connected to the sheath 20 by means of an adapter 56.
  • an electronics block 52 with a sensor block 51 and a power supply 53, which together with a reflector 30 form the target detection device.
  • the reflector 30 is articulated to the sheath 20 by four guide arms 41, 42, 43 and 44.
  • the corresponding abutment 36 with a spring 37 is attached to the reflector 30.
  • An articulation ring 55 which is connected to an autorotation parachute 60 by means of safety lines 61, is arranged on the casing 20.
  • the articulation ring 55 is connected to the sheath 20 by bands 62.
  • the casing 20 On the side facing away from the target, the casing 20 is closed off by a support structure 54, to which a textile swirl brake disc 58 is fastened by means of a coupling disc 59.
  • the textile brake disk 58 unfolds. This reduces the initially high sinking speed and speed of the submunition to predefinable values.
  • the support structure 54 is released from the casing 20 and the autorotation parachute 60 deploys and again reduces the sinking speed of the submunition body, a low, essentially constant speed of rotation of the submunition body being set.
  • the reflector 30, which is still in its rest position inside the casing 20, is no longer impaired in its mobility. The centrifugal force of the rotary movement of the submunition body, which acts in the center of gravity of the reflector 30, causes a pivoting movement of the reflector 30.
  • the reflector 30 is moved out of its rest position by the guide arms 41, 42, 43 and 44 acting in the sense of a parallelogram guide known per se from transmission technology Guided inside the envelope 20 into a working position outside the envelope 20.
  • the reflector 30 is locked in the working position simply and reliably by the spring 37 of the abutment 36 attached to the reflector 30 engaging in the corresponding groove 23 of the locking bearing 22 attached to the sleeve 20.
  • FIG. 2 shows a second exemplary embodiment of a submunition body 10 with one in a working position locked reflector 30.
  • An active body 57 on the side of the ammunition body 10 facing the target is connected to an envelope 56 by an adapter 56.
  • the reflector 30 has an effective surface 32 facing the target area.
  • the abutment 36 necessary for locking in its working position is attached to it.
  • the reflector 30 is articulated to the sheath 20 by advantageously four guide arms, of which the three guide arms 41, 42 and 44 can be seen in FIG. 2.
  • the two articulated connections (recognizable here by way of example) 25 of the guide arms 41 and 42 with the reflector 30 form a common axis of rotation 14.
  • FIG. 1 In the reflector 30 according to FIG.
  • the effective surface 32 which is designed in a particularly advantageous manner has a paraboloidal shape.
  • the reflector 30 In its working position, the reflector 30 is inclined so that the central longitudinal axis 12 of the submunition body does not perpendicularly penetrate an imaginary plane containing the edge of the effective surface 32.
  • the surface 32 of the reflector 30 which is inclined in such a parabolic manner advantageously enables a reflection of target-characteristic signals, for example of the millimeter-wave or optical range, to a sensor block 51 in the casing 20.
  • FIG. 3 shows a submunition body 10 according to FIG. 1 with a reflector 30 at rest in the interior of the casing 20, which is closed by an adapter 56 on the side facing the active body 57.
  • the target detection device of the submunition 10 in the case 20 comprises an electronics block 52, a power supply 53, a sensor block 51 and the reflector 30.
  • the center of gravity 34 of the reflector 30 lies outside the central longitudinal axis 12 of the submunition 10.
  • On the case 20 in the direction of the pivoting movement 70 is a locking bearing 22 with a groove 23 attached.
  • a corresponding abutment 36 with a spring 37 is attached against the direction of the pivoting movement 70, which in a particularly advantageous embodiment additionally has a leaf spring 38 which serves as an additional securing means for the locking.
  • a linkage ring 55 and above it a support structure 54 which closes the submunition body 10.
  • the two guide arms 41 and 42 are fastened to the reflector 30 in two articulated connections, these two articulations having a common axis of rotation 14.
  • the two guide arms 41 and 42 are also fastened to the casing 20 in two articulated connections, these two articulations forming a common axis of rotation 17.
  • the two guide arms 43 and 44 are fastened to the reflector 30 in two articulated connections, these two articulations forming a common axis of rotation 15.
  • the two guide arms 43 and 44 are also fastened to the casing 20 in two articulated connections, these two articulations forming a common axis of rotation 16.
  • All axes of rotation 14, 15, 16 and 17 are parallel to one another and are perpendicular to the sectional plane containing the longitudinal axis 12 of the submunition 10 in the illustration in FIG. 3 (paper plane).
  • the direction of the pivoting movement 70 and the center of gravity 34 of the reflector 30 lie in this paper plane.
  • the center of gravity 34 lies outside the central longitudinal axis 12 of the submunition 10 and is displaced eccentrically on a diameter of the casing 20 in the direction of the pivoting movement 70.
  • the leaf spring 38 attached to the rear part of the abutment 36 is in the relaxed position shown in FIG. 3 in the relaxed state.
  • the effective surface of the reflector 30 points in the rest position against the active body 57.
  • the reflector 30 In the rest position shown in FIG. 3, the reflector 30 is held in the interior of the shell 20 by the articulation ring 55 and the support structure 54 and its mobility is hindered.
  • the centrifugal force which results from the rotational movement of the submunition body 10 about its central longitudinal axis acts in the center of gravity 34 of the reflector 30.
  • the action of the centrifugal force at the center of gravity 34 of the reflector 30 generates a torque about the axes of rotation 14, 15, 16 and 17, so that the reflector 30 is pivoted from its rest position inside the casing 20 into a working position outside the casing 20.
  • the center of gravity 34 of the reflector 30 is moved during the pivoting movement in the direction of the pivoting movement 70 along a path curve of the most general elliptical shape that can be represented in the paper plane.
  • FIG. 4 shows a submunition 10 according to FIGS. 1 and 3 with a reflector 30 locked in the working position.
  • the reflector 30 has an effective surface 32 directed towards the target, which forms an angle 18 with a plane perpendicular to the central longitudinal axis 12 of the submunition 10 forms.
  • Two guide arms 41 and 42 (of preferably four guide arms 41, 42, 43 and 44 according to FIG. 1) are shown as examples, forming with the reflector 30 articulated connections 25 and 26 and articulated connections 27 and 28.
  • the reflector 30 In the working position shown, the reflector 30 is locked, an abutment 36 attached to the reflector 30 engages in a locking bearing 22 attached to the casing 20 leaf spring 38 attached to the abutment 36 on an edge 24 of the locking bearing 22 facing the interior of the casing 20 and additionally secures the locking.
  • the shortest distance of the articulated connection 25 on the reflector 30 to the articulated connection 27 on the sleeve 20 projected into the plane of the sectional view (paper plane) shown in FIG. 4 is the lever arm length of the guide arm 41.
  • the shortest connection between the projected into the paper plane of FIG the articulated connection 26 on the reflector 30 and the articulated connection 28 on the sheath 20 is the lever arm length of the guide arm 44.
  • the lever arm length of the guide arm 41 corresponds to FIG. Double the lever arm length of the guide arm 44 does not exceed.
