Definitions

  • the invention relates to a grenade with an explosive core and an impact detonator and preferably an insulating insert, a splinter jacket, a front pipe protection device and a self-destructing device grenade shell, the impact detonator consisting of a shell-associated fixed part and a shell part axially displaceable relative to the shell .
  • DE-A-34 41 556, DE-A-36 20 784 or WO 87/01193 show, there are grenades with impact detonators for igniting the existing explosive core in a wide variety of designs, increasing the explosive effect and Improving security, an insulation insert, a splinter jacket, a pipe protection device and a self-destruction device can be installed in the grenade.
  • the insulation insert encloses the explosive core and, due to the resulting explosive dam, leads to a higher splinter speed
  • the splinter jacket consists of a plastic body with cast-in splinters, so that a predetermined splintering occurs when the grenade explodes
  • the fore-pipe safety device ensures this that the grenade only becomes sharp after it has left the gun barrel and only after a certain firing range, and the self-destruct device is intended to destroy the grenade if the impact detonator fails to strike.
  • These additional grenade parts are commercially available as prefabricated individual parts of different designs and can be installed in the various grenades as required. 5
  • the known impact detonators are composed of a fixed part and a striking part, one of the parts having a primer and the other having an ignition pin, so that when the grenade is opened due to the inertia
  • the striking part moves against the fixed part and the grenade is ignited by inserting the firing pin into the primer.
  • the striking part In order to guarantee the desired safety against ignition, the striking part must therefore have a sufficient mass, which has hitherto been the use of its own
  • the invention is therefore based on the object of eliminating these deficiencies and creating a grenade of the type described at the outset which is distinguished by its relatively simple structure, its high level of ignition and operating safety and last but not least by its low number of hits.
  • the invention solves this problem in that a
  • striking part of the impact detonator forms which structural unit is secured in a starting position by means of a positive and / or non-positive holder provided as the intended release point.
  • This unit is made up of components of the grenade that are present anyway and does not need its own striking piece, and a striking part of relatively large mass is also available, so that the launch or impact of the grenade releases high inertia forces and the desired response ⁇ sensitivity is guaranteed.
  • the assembly In order to prevent an undesired movement of the assembly within the shell, the assembly is fixed in a starting position by means of a holder, which holder is broken up by suitable target release points when an axial load exceeding a certain limit value occurs due to the inertia and produces the mobility of the assembly required for ignition.
  • the target release points can be dimensioned relatively strong, so that despite the sensitivity, a high level of operational security is guaranteed and no accident due to unskillful handling or dropping of the grenade must be feared.
  • the lack of a separate striking piece for the impact detonator allows for a simpler construction of the grenade with fewer individual parts; for a given total weight, the proportion of explosives and fragments can be increased accordingly, the possibility of largely centering the existing masses around the longitudinal axis of the grenade leads to less scatter of hits and the high mass forces that occur allow the use of robust, rationally producible individual parts.
  • the structural unit can include at least a part of the splinter casing, as a result of which the effective mass of the structural unit 5 is adapted to the respective circumstances within wide ranges can be adjusted.
  • the assembly can include the explosive core alone or together with the insulation insert and the front pipe protection device, or additionally also the entire splinter jacket or, in the case of a split splinter jacket, a part of this jacket, depending on the design of the assembly, the holder or the intended release point must be provided between the grenade parts belonging to the structural unit and the grenade parts belonging to the grenade shell.
  • brackets and the intended release points are designed, they can be non-positive and / or form-fitting, and it also does not fundamentally matter where the starting position of the structural unit is relative to the shell shell in one front position, a rear position or also an intermediate position, since due to the firing of the grenade on the one hand and the impact of the grenade on the other hand, mass forces occur in opposite directions and always ensure the required release and impact energy.
  • the structural unit is seated in axial guides, so that a swirl movement forced when the grenade is fired by a drawn weapon barrel of the grenade casing is also forcibly transmitted to the structural unit and this swirl movement is used to actuate the front pipe safety device or the self-destruction device or the like. lets use.
  • the axial guides result in a certain stiffening of the grenade casing and deformation-related impairments of the displaceability of the striking part are eliminated.
  • the bracket can be made from one
  • the impact detonator has an ignition pin belonging to the fixed part, which, in a front starting position of the structural unit, forms a locking pin for the front pipe safety device arranged on the fixed part side of the structural unit.
  • the front pipe safety device is activated and, after a certain period of time, activates the grenade, whereby the actual function of this front pipe safety device is irrelevant, which brings the primer into the ignition position due to centrifugal force or spring force. If the grenade now hits, the structural unit is thrown forward and the firing pin strikes the positioned primer instead of the blocking opening of the front pipe protection device and the grenade ignites.
  • a safety spring loading the structural unit opposite to the direction of impact is provided, it is ensured that after the grenade has been fired, the delay in flight speed caused by the air resistance cannot lead to premature ignition of the grenade.
  • the safety spring compensates for this delay conditional inertia, but can easily be overcome by the large mass forces that occur when the grenade is opened.
  • the grenade casing in the hood has a coaxial receptacle for the fixed part of the impact detonator and optionally the self-destruction device, a helical spring wound around the receptacle forming the securing spring.
  • a receptacle allows a central and space-saving arrangement of the fixed part and the self-destruct device and also offers the safety spring a clean, centering support.
  • the type and mode of operation of the self-destruct device again plays no role, and due to the large mass of the structural unit, ignition failures hardly occur from the outset even when the grenade is hit on soft ground.
  • FIGS. 1 and 2 FIGS. 3 and 4, FIGS. 5 and 6, and FIGS. 7 and 8 each show an exemplary embodiment of an inventive grenade in the axial direction cut or in cross section, the figures in the left half represent the starting position and in the right half the shot position.

  • the assembly 11 is secured in position in a front starting position via brackets forming set loosening points 14, so that the assembly 11 is only released after overcoming these set loosening points 14 and can move relative to the shell 2.
