Definitions
- the invention relates to a ground detonator for a grenade, which can be fired from a tube with the aid of a propellant charge and contains an ignition chain, with an impact ignition device consisting of a detonator charge and an axially displaceable striking element with an ignition needle, and with an adjustable one perpendicular to the grenade axis, the blocking element carrying the detonator charge, which interrupts the ignition chain in a secured position, unlocks it by firing, and closes the ignition chain in the active position, a receiving space for a delay sentence firing on firing being delimited by a destructible partition.
- a grenade with such a base igniter can be found, for example, in WO 87/01192.
- the striking piece shown there is provided with two opposing ignition pins.
- a spring-loaded adjustable slide perpendicular to the grenade axis serves as the locking element, which is held in front of the launch by a locking pin which is displaceable in the longitudinal direction of the grenade and unlocks during the launch.
- the two firing needles of the striking piece one is intended for the actuation of a primer of a pyrotechnic set, which is delimited by a partition, and the other for the direct actuation of the detonator charge.
- a self-ignition delay set which ignites at the same time represents a section of a second ignition chain which bypasses the impact ignition chain, a second detonator charge being provided in the slide which closes the second ignition chain in the active position.
- a grenade equipped with an impact detonator which contains a self-dismantling.
- a fuse link is provided there as a down pipe protection, to which a heating set is assigned and which fixes a sleeve which contains a deceleration set and an impact piece.
- the ignited heating element melts the melting member so that the sleeve is released and ignites the delay element which acts on the striking element when the impact igniter fails.
- the slide can move, making it possible for the firing pin to pass through to the detonator upon impact. If this does not occur in the intended manner, the self-igniting primer, which initiates the action of the detonator by the rear firing needle, is ignited shortly thereafter by the longer-burning second retardation primer.
- EP-PS 48204 The construction of an increased gas pressure to initiate a process is also known from EP-PS 48204.
- a transfer charge is separated from the main charge to be ignited by the slide, and a delay charge is then connected to it, the connection to the launch propellant charge being blocked via a locking piece provided with a pinch ring that can be moved parallel to the axis before the launch.
- the closure piece When fired, the closure piece is only moved forward under the action of the propellant gases when the gas pressure is sufficient to compress the squeeze ring.
- the functional safety of the slide release is improved by the gas pressure required for the compression of the squeeze ring.
- the invention has now set itself the task of creating a ground igniter of the type mentioned with improved front pipe security, in which a sufficient gas pressure is available in any case for the action of the striking piece for self-dismantling.
- a second hammer with an ignition needle is arranged in a second hammer bore running parallel to the first hammer bore and the partition divides the receiving area from the first hammer bore for the ignition of the delay set.
- the partition can be of any type, preferably it consists of a lead disc resting against a stop.
- the second percussion piece When fired, the second percussion piece acts on the primer due to its persistence, the impact may be dampened by a weak spring, and ignites the delay set arranged in the receiving space.
- the locking element is usually additionally locked in the secured position before firing, for example by a recoil bolt and / or a spring-loaded, twist-evasive bolt, etc. After the locking element is released, it is moved into the active position, whereby the ignition chain closes.
- the first striking piece hits the detonator charge that can now be acted upon, which detonates the explosive charge or the like. detonates.
- a hollow charge or the like can also be in the front part of the grenade. be arranged. If the impact ignition is not reached, sufficient gases have formed from the delay set to ensure that the detonator is acted upon by the pressure build-up with subsequent spontaneous breakthrough.
- the receiving space of the delay set is designed as a diametrically extending channel into which the second striking hole opens on the one hand, and which on the other hand merges into an axially offset radial connecting channel to the first striking hole.
- the maximum length of the deceleration set is generated, which generates a very high gas pressure.
- the effect of the combustion gases is further improved if the second striking hole extends over the bottom part and the axially adjoining housing of the locking element, the second striking piece in the section lying in the housing and the primer in the section of the second striking hole in the bottom part Distance to the underlying receiving space of the delay set is arranged.
- the distance between the primer and the delay set provides a space that initially fills with combustion gases, which means that the partition cannot be destroyed prematurely.
- a simple manufacture of the floor igniter according to the invention can be achieved if the receiving space is formed by a circumferential blind bore which is covered by a screw plug, and that the destructible partition wall which bears an overall outlet bore of smaller diameter in the connecting channel lies against the bottom of the blind bore.
- the manufacture of the connecting channel and the transition between the two channels can also be simplified if the gas outlet bore and the connecting channel open on the bottom side into a depression in the form of a threaded bore on the circumference of the base part, into which a second screw plug is inserted.
- the base igniter to be used in a grenade (not shown), in particular a 40 mm grenade, has one Bottom part 1 on which a housing 2 containing the locking element 3 is arranged. This takes up an inhibitor provided with a swirl protection 4, which is assigned to a carrier of a detonator charge 5. After loosening the swirl safety device, the carrier rotates, braked by the escapement, into the active position, in which the detonator charge 5 lies in the grenade axis and is aligned with a first striker 6, which is arranged in a first striker bore 8 and is braked by a spring.
- a second striking piece 9 is arranged in an axially parallel, second striking hole 10, which continues in the bottom part 1 as a blind hole.
- a primer 11 is inserted, which is acted upon by the firing needle 20 when firing due to the persistence of the second spring-braked hammer 9.
- the section of the second percussion bore 10 below the primer 11 is empty and forms a collecting space for combustion gases which develop from a deceleration set 12 ignited by the ignition jet.
- the delay set 12 extends in a receiving space 13 formed by a diametrical bore, into which the striking hole 10 opens on one side and which is closed by a first circumferential locking screw 15.
- an outlet bore 16 of reduced diameter is provided, which opens into a threaded bore into which a second, circumferential screw plug 17 is inserted.
- a partition 14 which delimits the receiving space 13 for the deceleration set 12.
- a radial connecting channel 19 In the threaded hole closed by the second screw 17 opens at an axial distance above the Receiving space 13, a radial connecting channel 19, the diameter of which corresponds approximately to that of the outlet bore 16, which ends in the first hammer bore 8.
- the second screw plug 17 is provided with a recess 18 connecting the outlet bore 16 and the connecting channel 19.
- a propellant charge cartridge 21 is inserted, via which the grenade is fired.
- the second striking piece 9 ignites the primer 11 and this the first slowly burning section 22 of the deceleration set 12.
- the inhibitor is released, the swirl device 4 of which is released due to the rotation of the grenade , so that the detonator charge 5 can pivot into the grenade axis.
- This process which is slowed down by the inhibitor, extends over a first period in which the desired fore-pipe safety is ensured, since the first impact piece 6 cannot act on the detonator charge 5 during this period.
- the first impact piece 6 When striking the target, the first impact piece 6 is flicked forward and its firing pin 7 pierces the detonator charge. If the serve is too soft or the target is missed, the grenade will disassemble itself.
- the deceleration set 12 which burns during the flight generates combustion gases which enter the free space of the second striking hole 10, a gas pressure resulting from the cutting disc 14 until the deceleration set 12, which is a fast-burning charge in the second section 23 and which generates a large amount of gas, burns off builds up. This then causes the cutting disc 14 made of the material shown to burst, so that the gases under high pressure through the outlet bore 16, the recess 18 and the connecting channel 19 flow into the first hammer hole 8.
- the first impact piece 6 thus causes the detonator charge 5 to be ignited even without a corresponding surcharge.
- the time until self-disassembly can be set by appropriate selection of the delay set 12 and the cutting disc 14, the fore-pipe safety being ensured until the detonator charge is pivoted into the grenade axis.
- a lack of swirl or impact immediately after firing therefore does not lead to detonation, rather the first striking piece is flung forward due to the high gas pressure of the deceleration charge, the firing pin wedging in part of the carrier or the inhibitor.
