Definitions

  • the invention relates to self-protection launchers, such as those used for protecting tanks.
  • the launcher device consists of a plurality of launcher tubes, which are attached to a suitable location on the outer surface of the tank, and throwing bodies inserted into the launcher tubes, which contain a propellant charge and an active charge, the latter mostly being a fog charge.
  • the projectiles are ignited electrically from the inside of the tank, ignition contacts being arranged in the launch tube, which are in contact with contact rings located on the casing of the projectile.
  • Contactless namely inductive ignition systems are also known.
  • the electrical energy received via contacts or contactlessly is used to ignite the propellant charge, in which case the hot propellant gases in turn ignite the active charge via a pyrotechnic ignition chain with a delay element.
  • the safety and effectiveness of the protective measure are of particular importance in such a throwing device. It must be ensured that there is no ignition of the active charge in the launch tube (pipe safety) or in the vicinity of the pipe mouth (front pipe safety and rail safety), the latter not even if the projectile hits an obstacle (tree) before it reaches its specified firing range meets. These safety problems also arise when the active charge is ignited not by a pyrotechnic ignition chain but by an impact detonator.
  • the effectiveness of the protective measure depends, on the one hand, on the accuracy of the missile and on the other hand on the time between the time the missile was fired and the onset of protection, i.e. the formation of the cloud of fog.
  • the throwing body In today's launcher devices of this type, the throwing body is usually shot at an angle of 45 ° with respect to the horizontal, so that the trajectory of the throwing body is very steep, which leads to a comparatively long flight time with the consequence of being effective late and also causing problems, to allow the active charge to take effect exactly at the desired height above the ground, because the throwing body gains high speed in the steep fall phase of its trajectory, with which even the smallest deviations in the ignition timing have a considerable influence. Due to the further development of the attack measures, one is now also forced to improve the protective measures, in particular to ensure that protective effects occur faster than before. For this reason, efforts are being made to move from the previous steep trajectories to much flatter trajectories, down to 10.
  • the object of the present invention is therefore to improve self-protection launcher devices of the type described so that safety and accuracy (to be defined later) are ensured even with a flat and short trajectory.
  • the solution to this problem results from the characterizing features of patent claim 1.
  • the projectile therefore remains connected to the launch site after it has been fired via a safety line and this safety line is dimensioned in such a length that it reaches its full extent when the specified range is reached by the projectile, with the result that it has the
  • the throwing body brakes abruptly, tensioning the firing pin spring and releasing the firing pin so that it ignites the active charge, for example via a primer and a primer.
  • the actual range of the throwing body is thus determined by the length of the suspension line, which can be done very precisely and leads to an unusually high accuracy.
  • the firing pin spring is only tensioned by pulling the safety line and the firing pin is then released, which leads to very high tube, down tube and rail safety.
  • suspension line is slightly shorter than the range specified by the propellant charge or the propellant charge would allow the throwing body a slightly larger range than is permitted by the suspension line, because only then does the jerk required for tensioning the firing pin spring occur. If the throwing body hit the ground exactly at the distance from the launch point, which corresponds to the length of the line, there would be no ignition of the active charge. Even immediately before the desired meeting point, there is still a high level of security (final phase security).
  • the throwing body has a cup-like housing sleeve 10, the area adjacent to the cup base is thickened and the front cup opening is closed by a cover 11, which is also the base of a spontaneous active charge to be explained later; the lid 11 is held by means of a flange of the sleeve edge, a sealing ring 12 ensuring a watertight closure.
  • the secondary side of an inductive ignition system consisting of a ferrite core 13 and a transformer coil 14, is attached to the bottom of the cup.
  • a comparatively massive and heavy anchor cover 15 with a central bore sits on the bottom of the cup, on which in turn a propellant chamber housing 16 sits, which contains a propellant charge chamber 17 filled with propellant charge 17 18 surrounds.
  • the propellant charge chamber 18 is covered by a thin film against the central bore of the anchor cover 15, in which an ignition pill 19 is located.
  • a suspension line primary part 21 which consists of comparatively short suspension lines which are held at one end on the drive chamber housing 16 and at the other ends on the anchor cover 15, which in turn is attached to the cup bottom by means of a separating element 22 and a time delay piece 23.
  • Six primary lines 21 of this type are provided coaxially to the longitudinal axis of the throwing body.
  • a drum 24 for the secondary secondary line 25 which consists of a comparatively long safety line, which is attached at one end to the drum 24 and at the other end to a central piece 26 which is in the central opening of the ring base 27 of a point mist body container to be explained later.
  • a central support tube 28 From the central opening of the ring base 27 there is a central support tube 28, in which a piston rod 29 is slidably mounted, which is attached at one end to the central piece 26 and at the other end is connected to a firing pin 31 by means of a coupling piece 30.
  • a firing pin spring is designated.
  • a point mist charge 33 consisting of ring bodies is accommodated, which is covered on the end side by a compensating disk 42 and on the other hand by an ignition distributor cover 34.
  • the ignition distributor cover 34 contains an ignition cap 35, which is located in the path of movement of the firing pin 31, a transfer charge 36, a delay piece 37 and an ignition charge 38 for the point mist charge 33.
  • a spontaneous mist body 39 is arranged on the outside of the ignition distributor cover 34, in which is located in extension to the firing pin axis, an ignition splitter charge 40 which is connected to the transfer charge 36 via an opening in the ignition distributor cover 34.
  • the point mist body container 41 is connected to the spontaneous mist body 39 via coupling pins 43, so that an active charge double body results.
  • the anchor cover 15 with the separating element 22 and the delay piece 23 and the secondary part 13, 14 of the ignition system remain in the launch tube.
  • the primary part 21 of the suspension line which is fastened at one end to the propellant charge housing 16, is carried along with the double throwing body.
  • the length of the six individual lines of the primary part 21 is such that they are completely tensioned when the double body has left the mouth of the housing sleeve 10, at which point in time the propellant charge 17 also burned off.
  • An example value for the length of the primary part 21 of the safety line is 0.5 m.
  • the projectile is, for example, at a distance of 45 m from the launch site and at a height of 4.5 m above the ground.
  • the ignition occurs in such a way that the secondary part 25 of the suspension line pulls jerkily on the central piece 26, with the result that the firing pin 31 is pulled backwards via the piston rod 29, the spring 22 being tensioned.
  • the "jerk” mentioned is damped in such a way that comparatively small suspension line cross sections can be used; the damping results on the one hand from the elasticity of the tether system and on the other hand through the air column 44, which is compressed by the piston rod 29.
  • the firing pin 31 strikes a stop, and as a result of the further pulling of the suspension line on the central piece 26 and thus on the piston rod 29, the coupling piece 30 breaks, that is to say the connection between the piston rod 29 and the firing pin 31 is released, so that the firing pin 31 strikes forward through the now relaxing spring 32 against the primer 35.
  • This movement is supported by the inertia of the firing pin.
  • the primer 35 struck by the firing pin 31 ignites the transfer charge 36, which in turn ignites the igniter charge 40, which leads to a spontaneous development of fog due to the fog charge 39; the transfer charge 36 also ignites the time delay piece 37, which, after a certain time delay, ignites the ignition charges 38, with the result that the point fog charge 33 begins to form fog.
  • the hot propellant gases generated when the propellant charge 17 burned off also ignited the time delay piece 23 via a suitable channel. Its time delay is such that when the point mist body has reached the bottom, for example 2 seconds after firing, it has burned out and ignites the separating device 22, which releases the connection on the anchor cover 15 to the housing sleeve 10; the lines are thus separated from the part of the throwing body remaining in the launch tube. This is also indicated in sketch D of FIG. 2.
  • the safety line system ensures an exact ignition at the desired distance from the launch site, at a predetermined height above the ground.
  • the throwing body as in the exemplary embodiment, is a double body
  • the problem is how to operate the double body at a speed of about 150 km / h at a target point, the front body above the ground and the rear body should release a cloud of fog on the ground. Both clouds of fog should mix, i.e., form an overall cloud standing spatially one above the other. To achieve this, an extremely precise ignition is obviously required, and this is achieved with the safety line system described.
  • the interception of the propellant charge housing 16 and the drum 24 by the primary safety lines 21 shortly after the double body emerges from the mouth of the housing sleeve 10 is important; this means that the center of gravity is shifted forward on the double body, with the result of an exact flight of the double body with exact unwinding of the secondary suspension line.
  • the safety line system By dividing the safety line system into a primary part consisting of several safety lines and a secondary part consisting of only one safety line, a high safety line safety in the area of the hot propellant gases is achieved without taking up too much space and weight for the safety line system in the throwing body.
  • the front end of the secondary secondary line can also be divided into several individual secondary lines in order to obtain the most axial possible pull on the central piece 26.
  • a strain relief in the form of a clamping ring 45 is provided for the firing pin 31, which prevents tensioning of the firing pin spring 32 during the flight. Only the interception energy at the target point overcomes the clamping force of the ring 45 and then allows the spring 32 to be tensioned.
