Definitions

  • the invention relates to a mortar detonator with a wind turbine according to the preamble of claim 1.
  • a wind turbine generator which is characterized by the Wind wheel rotating in the air flow to generate the energy for the detonator and for driving the safety device serves
  • Such wind turbine generators have the disadvantage that the energy generated depends on the speed of the wind generator, which is at the apex the trajectory of the mortar can drop to zero. This can lead to a power cut, at least lead to impairment of the reliability of the igniter.
  • Another problem is that the wind turbine freezes and during flight can come to a standstill, also with the problem of energy failure.
  • the invention has set itself the goal of creating a mortar detonator of high reliability, in which the power supply of the igniter does not depend on a constant rotation of the Wind turbine depends.
  • the invention solves this problem according to the feature of the invention Main claim.
  • the invention is therefore based on the fact that by using a known activatable Battery during the flight an activation wheel driven by the wind wheel with a predetermined time delay between firing the projectile and reaching the Activation position is activated. Depending on the type of battery used, activation is required again a certain period of time before the battery is fully functional. At the latest At this point, the speed of the igniter is no longer important of the wind turbine.
  • the Invention provided that the activation wheel along a worm gear on the axis of rotating wind wheel can be moved and brought into contact with the activatable battery.
  • the activatable battery from a battery container with the battery cells and one immediately adjacent, but separate acid container, the latter by the Activation wheel is piercable, causing acid to flow into the battery container.
  • the activation wheel has a magnet that turns on its rotation passes a coil and generates energy.
  • This energy is used to power the battery during the activation phase Igniter and in particular for the energy supply for a counter that the time function of Zünders controls.
  • one, one or more Emergency power supply containing capacitors is provided, which with the Activation wheel works together and the function of the counter in any Power failure of the battery ensures.
  • the emergency power supply is also with the Can be used with a wind turbine generator.
  • Fig. 1 the essential components in connection with the invention are one Mortar detonator drawn in a highly schematic representation.
  • 1 is a wind turbine, with 2 a battery, with 3 the safety device, with 4 the electronics and with 5 the ignition designated.
  • the battery 2 consists of a battery container 6 and battery cells 7.
  • the battery container is in the idle state of the igniter, i.e. in the not shot down Condition, no acid.
  • the battery is therefore not yet functional.
  • Above the Battery container is an acid container 8, which in the activation case after Launch is destroyed, so that the acid in the battery container below can drain.
  • the battery container and the acid container are each annular and form one cylindrical space, which is penetrated by the axis 9 of the wind turbine.
  • a worm gear 10 is attached, on which in turn a gear 11 is longitudinally displaceable can move.
  • the gear 11 runs along the Worm gear 10 upwards and destroys the acid container 8.
  • Electric coil 12 which has a magnetic assignment 13 on the gear 11th cooperates and in which when the gear rotates energy for the power supply the igniter and any emergency power supply are generated.
  • a double bolt is designated, which is the primary The fuse system of the detonator is released when fired and thereby the wind turbine 1 releases.
  • This double bolt is a common component in detonators and will not be described here described.
  • a worm wheel 15 and a serves for the mechanical release of the safety device 3 Safety bolt 16.
  • the worm wheel meshes on axis 9 and works with one Worm gear on a safety pin 16 together.
  • axis 9 is rotated unscrewed over the worm wheel 15 of the locking bolt 16 and the Security device 3, which has a mechanical detonator 3a and an ignition transmitter 3b, released in focus.
  • a spring 13 serves to secure the arming device.
  • the ignition electronics 4 consists of an ignition circuit 4a and an electrical detonator 4b and is powered by the battery or coil 12.
  • the worm wheel 15 is rotated by the axis 9 and in turn rotates the Safety bolt 16 out of its rest position, whereby the safety device 3rd released and pressed by the spring 3c in its focus.
  • the detonator is now fully focused.
  • This emergency power supply will charged by the current pulses generated in the coil 12 by the magnet 13 and stores its energy content for the duration of the flight of the projectile.
  • the coil 12 A rectifier 17 is arranged downstream, to which a first supply capacitor 18 is connected for the power supply of the downstream ignition electronics 19 and a second Supply capacitor 20 are connected to a subordinate time counter 21.
  • On Controller 22 serves to control the ignition electronics 19 and the time counter 21 Speed of the wind turbine 1 and thus the output voltage of the coil 12, under one predetermined threshold value, the controller 22 is switched via the rectifier 17 and switches off the ignition electronics 19 as well as itself.
