Definitions

  • the invention relates to a mine, on which legs are articulated, which can be spread away from the mine by means of a drive device having two drive stages for erecting the mine, the mine having a sensor device for detecting a target vehicle to be combated.
  • an underwater weapon with legs which can be spread away from the underwater weapon by means of a drive device for raising it.
  • the drive device has two drive stages, the first drive stage taking effect first being a spring element with a large spring constant, and the second drive stage taking effect after the first drive stage being a spring element with one in comparison to Spring constant of the first spring element is small spring constant.
  • the first spring element is only used to spread the legs up to a certain spreading angle, while the second spring element is provided with a comparatively small spring constant to spread the legs when the bottom of the lake is reached in such a way that the underwater weapon is aligned precisely to combat an enemy target vehicle is.
  • This known weapon is not intended or suitable for use as a land mine.
  • DE 32 30 546 C1 describes a mine or a positioning device for a disposable shaped charge mine, which has positioning devices made of relaxing spring steel wires, which are held in the rest position of the mine and which are released after the mine has hit the ground and which are the alignment the hollow charge effective direction.
  • at least three spring washers are arranged in the area of the exit surface of the detonation products and are held in the rest position of the mine in the form of an eight folded in the middle and are released after the mine hits the ground.
  • the spring washers should be selected with such a spring constant that the mine is not erected or positioned too abruptly, because otherwise there is a risk that the mine will inadvertently change from a rest position to an aligned mine position in another rest position.
  • the invention is therefore based on the object of creating a mine of the type mentioned at the outset which remains in its lying rest position until a target vehicle to be combated is detected, so that the probability of discovering the mine prematurely from a target vehicle to be combated is very low is.
  • this object is achieved in that an active device is provided between the sensor device and the drive device, with which a spreading movement of the legs, which adjusts the mine from a lying rest position into its active upright position, only takes place when a target vehicle to be combated is detected, in that the first drive stage the drive device with a small drive force is intended to move the free legs not resting on the ground with a relatively low drive force from the rest position lying against the mine into a position folded away from the mine, and that the second drive stage of the drive device with a Compared to the driving force of the first drive stage, a large driving force is provided to act on the standing legs resting on the ground for setting up the mine.
  • the first drive stage of the drive device With the help of the first drive stage of the drive device, a comparatively smooth drive movement of the supporting legs takes place.
  • the first drive stage of the drive device opens up the freestanding legs that are removed from the ground on which the mine is located.
  • the free legs are about 90 degrees away from the mine in said first drive stage, so that advantageously an unwanted overturning of the mine is prevented.
  • the second drive level of comparatively large driving force is only effective when the free legs of the mine are opened. This results in a smooth and optimally timed installation of the mine in its active upright position without fear of an unwanted overturning of the mine.
  • the two drive stages of the drive device can act continuously one after the other on the pillars of the mine.
  • the two drive stages of the drive device can take effect in succession on the pillars of the mine.
  • the drive device can have a gas generator with drive pistons, the drive pistons preferably being operatively connected to the associated supporting legs.
  • the gas generator can have a throttled high-pressure / low-pressure system, the maximum of the gas pressure provided for erecting the mine at the drive pistons being continuously achieved within a certain period of time. Depending on the gas generator used, this time period can be of the order of magnitude between 100 and 200 ms. Of course, the gas pressure maximum can also be reached within a different period of time.
  • the gas generator can be precharged for generation a certain first gas pressure on the drive piston and a main charge for generating a certain maximum gas pressure provided for erecting the mine on the drive piston.
  • a gas generator works according to the so-called tandem principle in two stages, the relatively effective gas pressure resulting in the precharging first taking effect in the area of the drive piston, which causes the unloaded legs to spread away from the mine. If these unloaded, free legs have reached their position folded away from the mine with the help of the relatively low gas pressure of the precharge that takes effect first, the main charge is activated.
  • This main charge can be effective in accordance with the throttled high-pressure / low-pressure system described above, that is, the main charge can be used to continuously increase the gas pressure up to a maximum value, the actual installation process of the mine being carried out by means of the main charge or by means of the gas pressure caused by the main charge becomes.
  • a simple construction of the mine and reliable erection of the mine after the detection of a target vehicle to be fought is given if the drive device has a number of racks corresponding to the number of standing legs and each standing leg has a toothed segment meshing with the associated toothed rack, the racks being connected to the corresponding driving pistons are.
  • the flexible connecting element can be, for example, a rope, a chain or the like. act.
  • the mine according to the invention is preferably used as a land mine, it being possible for the mine to be ejected or ejected from an aircraft, for example, and brought to the ground by means of a parachute system known per se. Another possibility is to use the mine according to the invention as an underwater mine.
  • Fig. 1 shows a schematic representation of the mine 10 in a side view.
  • Legs 12 are articulated on the mine 10 and are adjustable between a rest position, as shown in FIG. 1, and a position spread apart from the mine 10.
  • the drive device 14 has a first drive stage 16 and a second drive stage 18, which are only indicated as blocks in this figure.
  • Reference number 20 denotes a sensor device which is also indicated schematically in FIG. 1 only as a block and which is operatively connected to the drive device 14 via an active device 22 which is also only indicated schematically as a block.
  • the sensor device 20 is provided for the detection of a target vehicle to be fought. For example, it can have an IR sensor.
  • the active device 22 between the sensor device 20 and the drive device 14 for the legs 12 are intended to trigger an erection of the mine 10 from a lying position, as indicated schematically in FIG. 2, into its erection position only when a target vehicle to be combated has been detected with the aid of the sensor device 20.
  • an arrow 24 is drawn between the sensor device 20 and the active device 22, by means of which the active connection between the sensor device 20 and the active device 22 is to be indicated. Accordingly, an arrow 26 is intended to illustrate the operative connection between the active device 22 and the drive device 14. The active connection between the drive device 14 and the legs 12 of the mine 10 is to be illustrated by two arrows 28.
  • the mine 10 is indicated in the rest position or lurking position lying on the floor 30, the advantage being that the probability of discovering the mine 10 prematurely from a target vehicle to be combated is significantly lower than the probability of detection of a corresponding one mine set up in its active erection position.
  • the legs 12 lie close to the mine 10 because the drive device 14, i.e. the first drive stage 16 and the second drive stage 18 of the drive device 14 are in the inactive state.
  • the reference number 20 also designates the sensor device and the reference number 22 designates the active device provided between the sensor device 20 and the drive device 14 according to the action.
  • the sensor device 20 activates the drive device 14 via the active device 22 in such a way that an upward movement of the lead 10 from the rest position shown in FIG. 2 to an active upright position he follows.
  • the first drive stage 16 of the drive device 14 which has a relatively small drive force, is effective in order to move the free, ie not resting on the ground legs 12 with a relatively low drive force from the rest position lying against the mine 10 into a position folded away from the mine To move position.
  • the one leg 12 is drawn both in the resting position against the mine 10 and in an intermediate position spread away from the mine 10.
  • the movement of the legs 12 caused by the first drive stage 16 of the drive device 14 is indicated by an arcuate arrow 36 in FIG. 3.
  • the second drive stage 18 of the drive device 14 takes effect, the second drive stage 18 having a large driving force compared to the first drive stage 16. With the help of this great driving force, it is then possible to move the mine 10 into its active erection position without fear of the mine 10 rolling over unintentionally, because this is prevented by the free legs 12 already folded away from the mine.
  • the drive device 14 comprising a gas generator 34, a throttle device 36 fluidly connected to the gas generator 34 and one of the number Legs 12 of the mine 10 (see FIGS. 1 to 3) have a corresponding number of drive pistons 38 which are fluidly connected to the throttle device 36.
  • a drive device 14 is indicated in a block diagram corresponding to FIG. 4, in which the gas generator 34 has a precharge 44 for generating a specific first gas pressure p1 (see FIG. 7) and a main charge 46 for generating a specific maximum gas pressure p max (see Fig. 7).
  • FIG. 8 shows a partially cut-away side view of a mine 10 drawn in sections with legs 12 drawn in sections.
  • the legs 12 are drawn in a position in which the mine 10 assumes the active erection position.
  • the reference number 14 in this figure also denotes the drive device with the gas generator 34.
  • the throttle device 36 which is fluidly connected to the gas generator 34
  • the drive piston 38 which is fluidly connected to the throttle device 36, can be seen.
  • the drive piston 38 is formed in one piece with toothed racks 48, which mesh with toothed segments 50.
  • the toothed segments 50 are rotatably supported around stationary bearing axes 52.
  • the corresponding legs 12 are connected in one piece to the toothed segments 52, so that an axial movement of the toothed racks 48 requires a rotational movement of the corresponding toothed segments 50 about the associated bearing axes 52 and thus a pivoting movement of the legs 12 away from the lead 10.
