Hock fuse.

The different types of projectile known up to now * Ignitors are generally very intricate in construction, very expensive, and take up a great deal of space or do not have the required operational reliability.

A known projectile detonator has an ignition release device arranged in front of the detonator and an ignition channel which is connected to the ignition release device via an ignition channel which is normally closed by a safety device Detonator, which due to the projectile acceleration occurring when firing the projectile between a front, inactive position in which he is outside the Projectile explosive charge is located, and a rear, active position in which it is located inside the explosive charge, can be displaced.

The invention aims to improve a projectile fuse of the type described above to the effect that absolute operational safety is guaranteed.

The projectile fuse proposed for this purpose in the The above-mentioned embodiment is characterized according to the invention in that the detonator is parallel to the projectile

The detonator forms that front end of a projectile and has a primer S and an ignition trigger on »The ignition trigger for the ignition set 3 works mechanically © the electrically and is in any case by the impact of the shot or actuated by a delay provision w & g, which when the shot is fired or when the Floor is put into operation.

In the first embodiment, an electric primer eats 3 provided, which is recovered by supplying electricity. D @ 2 »Electricity is supplied by a power generator "which, for example from a battery or any other power source can exist. The power supply to the ignition charge 3 takes place by a switch that closes when the projectile hits the ground will.

A lower sleeve 7 is on the lower end of the housing S. screwed on and provided with an external thread 8 for fastening the detonator on the projectile head. The attachment takes place (according to Fig. 5) by means of an intermediate piece 9 made of an insulating material such as Plastic that is ring-shaped and engages with its internal thread in the thread of the lower sleeve. The intermediate piece 9 also carries an external thread which is inserted into the front end of the explosive charge 10 containing Projectile can be screwed. The explosive charge is usually a cylindrically shaped explosive * charge in the form of an ignition mass 11.

The lower sleeve 7 is also used to attach a jacket 12, which encloses a cavity and in the operational β-position of the detonator inside the explosive charge 10 of the Bullet is in the extension of the fuse axis.

A guide sleeve 13 inserted into the lower section of larger diameter of the housing 5 runs with the Inner wall as an extension of the inner wall of the obAn section of the housing S. The upper end of the guide sleeve 13 has a smaller wall thickness and is not in contact with the annular shoulder 6 and forms an annular space IH. That lower end of the guide sleeve 13 carries an outer annular flange IS, the inner diameter of which is that of the shell 12 corresponds to the cavity formed, and whose outer diameter corresponds to that of the housing S.

The detonator 17 is located inside the Rohrmanschott® and is on the front side of the armor 18. Above the explosive asunder 17 is an upper armor 20 with a central recess or hole 21 _s which forms part of the ignition channel, which the primer 3 with the Detonator 17 connects o

The unit also includes the actual safety device which, when inactive or deactivated (shown in FIG. 1), closes the ignition channel & wiped ignition charge and detonator 17. The safety device consists of a cylindrical locking member 22 in the form of a bolt, the axis of which "runs perpendicular to the fuse area. The bolt 22 is linearly visible in the Iraqsron of a bore 23 in the upper armor 20" The ob @ The section of the armor 20 forms <ain @ guide and is arranged with a coaxially inside the detonator and access to the hole 23- forming opening or hole 2 **, as well as with a large diameter hole 2S ₉ whose upper section is below ® the end of the sleeve® encompasses the primer 3, and a piece in Forai eiaos Kopfatü @ k © 8 2S of the armor 20 is provided "which is slidably guided in the 6 @ häu @ ® S.

The pipe sleeve 19 is also folded into the upper armor above the bolt 2 2 so that the mutual axial position of the upper and lower armor and detonator are fixed to one another.

A spring 27, which is located between the outer annular flange 15 of the guide sleeve 13 and the head atuck 2 6 of the supports the upper armor, acts on the entire unit

3 0 9 8 11/0848

(namely from upper and lower armor and detonator) In an advanced position of rest, in which the upper The end face of the head piece 26 of the armor 20 rests against the inner end face of the upper sleeve U.

In this advanced rest position, the detonator 17 is outside and above the explosive charge of the projectile and is separated from this by the lower armor 18, whereby the ignition of the explosive charge 10 is made absolutely impossible, even if the detonator should be made to explode for any reason,

The detonator further includes a holding device through which the aforementioned unit from the parts 17, 18 and is held in the axial direction in the operating position. This holding device consists of an elastic ring 28, which acts in the radial direction outward and in a Groove 29 of the circumferential wall of the head piece 26 is arranged. In the operating position of the unit (from the parts 17, 18 and 20) the spring 27 is compressed, the detonator 17 is inserted into the jacket 12, and the elastic Ring 28 is supported against the ring shoulder βab and holds the entire unit in this operating position.

The bolt 22 of the securing device has an opening 30 which forms part of the ignition channel and in the operating position of the bore 21 is opposite. The angular position of the bolt 22 is determined by a pin 31 specified, which is fastened in the upper armor 20 and with its outer end in a running along a surface line around the circumference of the cylindrical bolt 22 Engages groove.

The bolt 22 is urged by springs 32 in the direction of its operating position. These springs are placed on guides 3 3, which each have a head piece,

which rests against the pipe collar 19, the. guides 33 are carried out through holes in the bolt 22.

On the bolt 22 there is also a blind hole 34 which, in the rest position of the bolt 22, is axial to the Bores 21 and 24 of the upper armor 20 is aligned. The blind hole 3 ** - has the same diameter as the hole 2 »». In the rest position, an ignition guide in the form of a guide bushing 35 is partially inserted through the bore 24 into the blind bore 34 and is there so that the rest position of the bolt against the action of the springs 32 before. The outside diameter of this guide bush 35 corresponds to the diameter of the bores 21 and 34. The internal bore or recess of the guide bush

35 forms part of the ignition channel.

The guide bushing has a flange at its upper end

36, which forms a support for a compression spring 37, which is located between the flange and the bottom of the bore 25 in the upper armor and the guide bush 35 surrounds. The compression spring 37 acts on the guide bush 35 in the direction of the front end of the detonator in a position in which this from the blind hole 34 of the bolt 22 is pulled out.

In the rest position of the igniter (shown in FIG. 1), any axial displacement of the guide bushing 35 prevented under the action of the compression spring 37 by a closure or locking ring 38, the upper flange 39 engages around the flange 36 of the guide bush 35. The circumferential surface of the locking ring 38 has a cutout of a special shape 40 (see FIG. 4), which is operationally connected to a pin fastened in the upper armor 20 41 cooperates. In the rest position, the pin 41 engages in the recess 40 as shown in FIG. 4 and prevents it

309 8 1-1 / 08 4 A -

BAD ORIGINAI,

any displacement of the locking ring 38 towards the front end of the fuse, so that the guide sleeve 35 can not perform any displacement and in turn the latch 22 in the Locked rest position.

As can be seen from FIG. 4, the cutout has a short one Leg 42 and a long leg 43. Both legs 42, 43 are each not straight, but have zigzag-shaped boundary walls, creating a straight line Displacement in the longitudinal axis of the fuse between pin Hl and cutout to is prevented.

The projectile detonator described above operates as follows In the rest position shown, the detonator 17 is outside the explosive charge 10 of the projectile carrying the detonator. Therefore, if the detonator 17 should be ignited due to an accident or the like, the explosive charge will not explode. The primer 3 with the detonator 17 connecting the ignition channel is also closed by the bolt 22, so that an unintentional Triggering the ignition charge 3 does not lead to the ignition of the detonator 17. The projectile is therefore defused and harmless in the rest position.

To arm the projectile, i.e. the detonator from the To bring the rest position into the operating position, no manipulations are required. Rather, this process takes place automatically when the shot is fired.

When the shot is fired or, in the case of a self-propelled projectile, for several seconds, the projectile will exposed to a very high acceleration, whereby the (from lower armor 18, detonator 17, upper armor 20 and safety device, all within the Pipe sleeve 19) unit acting inertial forces a

cause linear displacement of the same against the force of the return spring 27 towards the rear end of the detonator «With this axial displacement of the unit, the lower armor 18 strikes the bottom of the shell 12. The impact is dampened by a shock absorber« m »which, for example, consists of an elastically deformable ring is ₉ so that damage of the jacket "12 is prevented to the end of the axial displacement is the unit in b <ssug to the housing 5 in such a position that the οlastische retaining ring 28 is situated opposite the annular space Ik below the annular shoulder. 6 Therefore, the retaining ring 23 can expand outwards and the unit dös detonator © in dev operating "position lock. In this operating position, the detonator 17 is located within the explosive charge 10 surrounding the jacket 12.

Simultaneously and / or partially after relocation? Unit (17, 18, 19, 20) with respect to the housing 5, the locking ring 38, which is also subjected to the inertia forces, is displaced with respect to the upper armor 20 against the force of the compression spring 37 towards the bottom of the bore 25. This axial displacement of the locking ring leads to successive angular displacements in opposite directions due to the engagement of the pin kl with the leg H2 of the cutout 10. As soon as the ring rests against the bottom of the bore 25, the pin 41 is in the upper recess of the cutout HO.

The detonator remains in this intermediate position as long as that Projectile is accelerated or at least the Geechpß acceleration Inertial forces result which are greater than the restoring force of the compression spring 37. The ignition channel is still locked by the bolt 22. When shifting the locking ring 38 with respect to the upper armor, the guide bush 35 is inserted further forward into the blind bore 34 of the bolt 22 and holds

this against the application of the springs 3 2 in the rest position.

As soon as the projectile acceleration stops and the delay begins, the inertial forces that occur during this delay are supported by the force of the Spring 37 an axial displacement of the locking ring 38 and the guide bush 35 towards the front end of the detonator. However, this axial displacement is braked and slowed down by the fact that the pin 41 follows the zigzag path within of the leg 43 of the cutout must cover what alternately oppositely directed angles! Ring and thus a braking of the axial displacement of the same result.

As soon as the pin 41 hits the bottom of the cutout 40 at the with 45 has reached, the amplitude of the axial displacement of the locking ring 38 with respect to the upper armor 20 sufficiently large so that the rear end of the guide bush 35 completely out of the blind hole 34 of the latch 22 is pulled out. However, the end of the guide bushing still engages in the bore 24 of the upper armor 20 and is centered by this Detonator axis held.

From this moment on, the bolt 22 is released and can move so far laterally through the action of the springs 32 shift until it hits the pipe sleeve 19. In this position, the opening 30 is centered on the fuse tube and connects the inner bore of the guide book with the bore 21 of the upper armor 20. The ignition channel is free and connects the ignition charge 3 with the detonator 17. As soon as the ignition charge 3 is hit of the projectile is ignited, the resulting shock wave causes the ignition of the detonator 17, which is now

a passage 51 runs continuously through the whole body 50.

A spring 53 serves to hold the locking member or the bolt 22 to be rotated in the angular direction into a position in which the passage 51 is aligned with the axis of the bore 21 and the recess in the guide bush 35. These The spring is placed on the bearing journal H8 and is supported against this journal and the upper armor 20.

The other bearing pin 49 has a milled ring 54, which runs over approximately 90 ° and a channel for receiving a section of a ball 55 which is inserted into a recess in the upper armor 20. the The ends of the milled ring 54 together with the ball 55 define the angular position of the bolt in the operating position and limit its angular displacement under the action of the spring 5 3.

The operation of the second embodiment is similar to that of the first. As soon as the guide bush 35 has been pulled out of the blind bore 34 of the bolt 2 2, rotated this is angularly in its operating position, which is determined by the fact that the ball 55 at one end of the milled ring 54 comes into engagement. In order to brings the passage 51 the central recess of the guide bushing 53 in connection with the bore 21 and is the Ignition channel between ignition set 3 and detonator 17 free.

In the third embodiment (shown in FIG. 6) of the igniter, the holding device for the movable unit consists of a guide sleeve 56 which, as in the first embodiment in the lower section of the housing 5 is attached. The sleeve inner wall has an upper, frustoconically tapering section 57 and a

lower shoulder 58 on. From the jacket 60 protruding elastic claws 59 hold the detonator 17 between the lower armor 18 and an upper armor 61. In the rest position, these claws 59 are against the gauge frustoconical tapering portion 57 while they spread in the operating position under the shoulder 58 of the guide sleeve 56 and the position of the movable Set unit against the winching action of a spring 62, which is against the bottom of the shell 12 and the rear Front side of the lower armor 18 is supported. This spring 62 then holds the movable unit in the advanced one Rest position fixed.

The front face of the guide sleeve 56 presses a screen plate 63 firmly against a shoulder of the housing 5. The shield plate extends perpendicular to the axis of the housing 5 and has one or more recesses 64 which are located immediately next to the wall of the housing 5.

In this embodiment, the safety device, which is in the rest or inoperative position of the detonator the ignition channel closes, from the shield plate 63 and balls 65, which in a central bore 66 of the upper Armor 61 are used.

In the rest position shown here, the movable unit is held in such a position in which the rotating Front edge 67 of the upper armor rests against the faceplate 63. The circumferential front edge 67 is located on a circumference within the recesses 6H and there also the central bore of the armor 61 is closed by the balls 65, there is no connection to the ignition channel between one above the faceplate 63 located ignition charge 3 and the detonator 17. In addition, the detonator 17 is in this position.

309811/0848

outside the explosive charge and is separated from it by armor 18.

When the shot is fired, the movable unit consisting of detonator and safety device is underneath the influence of the projectile acceleration against the force of the spring 62 shifted to the rear. The armor impact 18 on the bottom of the shell 12 is cushioned by a shock absorber 68, which consists of an elastic member that is arranged in the vicinity of the casing bottom. The elastic claws 59 spread and get caught under the Shoulder 58, whereby the movable unit is held in the operative position in which the detonator is located located inside the explosive charge 10.

As long as the projectile is accelerated, the balls are held inside the bore 66, so that the ignition channel is locked, even if the front edge 67 of the upper armor is no longer in contact with the shield plate 63 «

However, as soon as the projectile is slowed down in its ballistic trajectory, the balls 65 are discharged forwards Hole 66 thrown out. From this moment on, the projectile is sharp, since the primer with the detonator connecting ignition channel is now free. The ignition channel consists of the recesses 64, part of the interior of the housing 5 and the bore 66 in the armor 61.

The muzzle security is in this form of execution ensures the balls 65, which only release the bore 66 as soon as the projectile does not accelerate further and experiences a counter acceleration.

The fourth embodiment shown in FIG. 7 is similar to the third in some structural details

309811/0848

Execution form. The holding device for the movable Unit consists of an elastic ring 69 "into one Groove 70 is used in the circumferential wall of the upper armor. The elastic ring acts with one shoulder 71 of the housing S together. In this way, the guide sleeve can be omitted.

The safety device consists of three instead of two balls 65, and the faceplate 63 is through one Membrane 72 replaced, which © by di® explosion of the primer gets destroyed.

At the moment the shot is fired, the movable unit of the parts 17 ₉ 18 ₉ 60 and 61 is displaced in the axial direction, the membrane 72 not changing its position, so that the balls 65 ′ can emerge from the bore 66 in the event of a delay.

The operation of the fourth embodiment corresponds exactly to that of the third embodiment _{5 in} that the ignition channel is only opened at the moment of the explosion of the ignition charge when the projectile hits, whereby the membrane 72 is torn. The primer can work according to the recoil principle or according to the principle of inertia «,

The housing 5 of the igniter is attached to the ignition assembly holder 7> f and closed at its front section by an end piece 77.

The movable unit of the detonator here consists of a lower armor 18, a detonator 17 and an upper one Ring 78 which holds the unit by means of a jacket 60. The jacket 60 has elastic claws 79 in the cooperate advanced rest position with a tapered portion of the upper end of the housing 5. In the retracted operating position, the claws 79 spread below the lower end face of the primer holder 74 and thus hold the movable unit against the action of the spring 62. So there is the Detonator 17 also here in the rest position outside the explosive charge and is in the operating position in this introduced.

In the advanced rest position, the movable unit assumes a position such that the lower armor is above dor channels 76 and thus any connection between the detonators 75 and the detonator 17 is prevented. Ea be noted that the ignition of one or more detonators is not sufficient to burst the jacket 12 and thus the Explosive charge 10 to detonate.
