Definitions

  • the invention relates to an ignition protection device according to the preamble of claim 1.
  • Such an ignition protection device is known from DE-AS 22 34 849.
  • it has significant functional disadvantages in that a mechanical locking mechanism in the displaceable wind turbine generator itself must act as the first securing criterion.
  • the second release procedure in the form of an explosion pressure applied to the wind turbine generator appears to be particularly susceptible to faults; to irreversibly deform a locking member by pushing the wind turbine generator further out of the projectile from its first position.
  • this process cannot be readily predicted kinetically, the explosion pressure applied to the carriage that displaces the wind turbine generator can lead to malfunctions in the generator, and the further displacement of the wind turbine generator laterally out of the projectile leads to undesirable influences on the flight dynamics of the projectile and on the inflow conditions of the generator. If the generator is to run for the entire flight time, it is cheaper to leave it in one position.
  • an ignition safety device for projectile detonators with a double rear-firing pin system as the first environmentally dependent unlocking criterion and a wind turbine system as the second environmentally dependent unlocking criterion is known.
  • the double recoil bolt system unlocks when the projectile of the projectile of the wind turbine system is fired, which then frees a memory shrink metal by frictional heat after leaving the launch tube in order to pull a locking pin out of a detonator carrier so that it can be pivoted into its focus.
  • the disadvantage is that it is not possible to delay the onset of the mode of operation of the wind turbine element compared to the firing-related response of the double rear-firing pin system, so that no further lubrication criteria can affect the unlocking process.
  • a safety device with a double rear-firing pin system is known, there for releasing a detonator carrier which can be pivoted under the action of an inhibitor.
  • the invention is based on the object of further developing an ignition protection device of the generic type in such a way that, with a small construction volume, the safety functions of the safety functions which can be clearly delimited from one another can be implemented in such a way that malfunctions of the wind turbine generator (in the course of the unlocking process) as well as of the projectile, especially during the course its critical initial or stabilization flight phase are largely avoided; while the criteria of the safety standard with regard to two mutually independent environmental releasing systems and also with regard to the avoidance of prestressed spring force elements on the releasing elements are to be met in the installation and securing phase.
  • the ejection of the projectile from its carrier provides the first environmentally-relevant unlocking criterion, which only leads to the tension compression spring for the detonator safety slide being tensioned and, at the same time, to its unlocking.
  • a control circuit that operates independently of the operation of the wind turbine generator provides an electrical unlocking criterion for releasing the wind turbine generator for the shift into its working position.
  • the flow towards the environment as the second environmentally dependent release criterion finally unlocks the safety slide, whereupon the detonator is moved into its focus.
  • an ignition protection device 11 With regard to the basic conditions with regard to the structure and function of an ignition protection device 11 according to the invention, reference is made in full to the same priority DE ⁇ A ⁇ 3418745 to avoid repetitions. However, in order to increase the security of the depot and handling, that ignition protection device 11 is provided, in the secured state, not yet to provide a loaded pressure accumulator (in the form of a prestressed feed compression spring 27). Instead, this compression spring 27 is only tensioned when the blocking action of the blocker 31 on the detonator safety slide 25 is released by means of an acceleration-dependent unlocking mechanism 50.
  • the release mechanism 50 is accordingly oriented in this transverse direction.
  • it consists of the proven so-called double rear-firing pin system, which responds to the ejection acceleration 51 as the first environmentally-dependent release criterion.
  • the inertia of a response pin 53 thus causes the projectile 12 to be ejected from its support (not shown) laterally relative to the ignition safety device 11, the direction of the ejection acceleration 51 and the force of a spring 54 until the bolt back end 55 allows the lateral displacement of a locking ball 56 releases.
  • the force element 43 is actuated from the control circuit 42, which is equipped with a separate energy source for this purpose, in order to pull the locking pin 19 out of the slide 16.
  • This is therefore pushed forward by its prestressed compression spring 17 until the lamellar wheel 22 of the wind turbine generator 21, which is designed for radial inflow, projects beyond the periphery of the projectile wall 14 after passing through the housing opening 23.
  • the ambient flow against the projectile 12, which is free-flying after being ejected, is the second environmental safety criterion that is functionally independent of the first.
  • the wind turbine generator 21 After a certain operating time, the wind turbine generator 21 has supplied the energy required to control the force element 44 for pulling the locking pin 26 out of the sliding guide 24 for the detonator 28. Since the unlocking mechanism 50, which acts as a function of the acceleration and which provided the first environmentally dependent unlocking criterion, also tensioned the compression spring 27, the safety slide 25 is now advanced to its arming position (not shown in the drawing), in which the detonator 28 with the transfer charge 29 prior to the combat charge 13 is aligned and a bridging switch 30 (for the electrical short circuit of the detonator control in the safety position) is open.
  • the detonator 28 is acted upon by the control circuit 42 with ignition energy supplied by the wind turbine generator 21 when ignition sensors (not taken into account in the drawing) respond due to the approach or target impact, or, if a target is missed, an inertial sensor 61 responds.
  • the locking pin 26 for the detonator safety slide 25 should come out of engagement too early, namely before the first environmentally-relevant unlocking criterion in the form of the functional sequence of the unlocking mechanism 50 has taken place - and thus before its compression spring 27 has been tensioned and before its locking ball 59 has come forward the beveled front of its flange 37 can dodge laterally, the detonator safety slide 25 is moved backwards by a tension spring 62; until then a locking member 63, for example a pin loaded by a compression spring 64, engages as a lock between the safety slide 25 and a surrounding fixed component of the ignition safety device 11.
  • the safety slide 25 can no longer be advanced, so the detonator 28 can no longer be moved in front of the transfer charge 29; the projectile 12 is thus securely locked as a dud.
  • the direction of advance of the wind turbine generator slide 16 differs from that of the detonator safety slide 25 in this exemplary embodiment.
  • a mutual arrangement of recesses and projections 67 is formed in the area of intersection of the slide 16 with the safety slide 25; which only then do not come into contact with one another when the wind turbine generator slide 16 has been advanced and has thereby released the advance of the securing slide 25 into the detonator arming position.
