DE2332347A1 - Delayed fuse for rotation stabilised projectiles - has connected train of discs around fuse axis - Google Patents

Abstract

The delaying unit for the fuse is a train of discs each of which has a central shaft and arcuate, concentric slot. Each disc has a pin which engages with the slot of the neighbouring disc. Each driven disc starts to rotate after its driving disc has completed its movement. This movement is started when the driving pin has arrived at the end of the driven slot disc. Hence the last disc begins to rotate only after all connected discs have completed their movements. After the discs have completed their movements the firing pin travel path is free to initiate the detonator. This delay mechanism is of extremely flat construction and two or three mechanisms can be stacked for prolonging the delay time.

Delay device for detonators of wing or twist stabilized projectiles

The invention relates to a delay device for detonators of wing-stabilized or twist-stabilized projectiles, consisting of several locking pieces grouped around a fuse axis, which are arranged one below the other in a specific order Locking means are provided in such a way that, with the release of the first locking piece, the other locking pieces are unlocked one after the other and thus clear the way for the firing pin or ignition pin or ignition contact.

Such delay devices are used specifically for the detonator of spin-stabilized projectiles in order to achieve improved pipe security. It essentially consists of a ring of several around the fuse axis in a plane grouped locking pieces, which all carry a pin, the position of which is chosen so that the locking pieces below the effect of centrifugal force swing outwards one after the other. As a rule, one must wrap around all locking pieces Ribbon spring to be overcome. After pulling out the locking pieces, they are so far outside of the central striking or Firing bolt, so that it can pierce the primer through the opening when the projectile hits the target.

Such delay devices have been around for many!

Proven for ι years. Only they have the disadvantage that sib can only be used for detonators of spin-stabilized projectiles.

The invention is therefore based on the object of creating a delay device for detonators that can also be used for twistless _? z. B. wing-stabilized projectiles is suitable.

According to the invention, the object is achieved in that the locking pieces from in a plane with their stub shafts in the Detonator housing are rotatably mounted disks, both with circular arc-shaped recesses in which the following Disc engages lockingly, as well as being provided with a movement mechanism that can be set in motion by its own drive are such that after the first disk is released and rotated, the other disks start rotating, when the previous discs have finished rotating.

The rotary motion mechanism according to the invention consists of a circular arc-shaped guide curve embedded in the disk, a stop pin engaging therein and one below the disc housed in a housing cavity, attached on the one hand to the stub shaft and on the other hand to the housing Clock spring.

Still according to another feature of the invention, the length of the guide curve is dimensioned so that it can be used to achieve a long deceleration path describes an arc of about 270,

Finally, according to another feature of the invention, the a control disk is assigned to the first and last disk,

which lie on the disk as second disks of larger diameter and at a small distance from each other and from the fuse axis are removed, the control discs with circular arc-shaped recesses for the passage of the firing pin or firing pin or the ignition contact are provided.

This extremely reliable function and the flat design make it possible to selectively use the delay device in this way to install the igniter so that it can be used for used for self-destruction at the highest point of the trajectory or for the function of the impact with delay will.

It is precisely the flat design that allows two or even three delay devices to be arranged one above the other, as a result of which the delay period can be extended by two or three times. . .

In the drawing, an embodiment of the invention is shown, namely show

Within the igniter housing 17 of a wing-stabilized or twist projectile, a ring of five disks 1 to 5 is grouped in one plane at the same distance around the igniter axis 8, which are rotatably mounted in the igniter housing 1 with their stub shaft l'i. Do the slices. 5 each have a control disk 6 and 7, which, with their larger diameter, extend almost to the cylinder axis 8. Each of the slices

1 to 5 is provided on the circumferential surface with a circular arc-shaped recess 9 with which it rests against the adjacent Seheibe. Furthermore, each disk 1 to 5 has an arcuate guide curve IO which extends over an angle of approximately 270. To limit the rotary movement, a stop pin 11 engaging in the guide curve 10 is provided. Furthermore, each disk 1 to 5 is provided with its own drive in the form of a winding spring 12, which with its inner end on the V.'e I lenstucipf lh running into a cavity I3 of the igniter housing 1 and with the outer end aa igniter housing 17 is attached.

The control disks 6 and 7 have smaller recesses 15 on the circumference than the recesses 3 of the disks i to ^r j.

The mode of action is as follows:

The pulling up or tensioning of the disks 1 to 5 is initiated by means of the control disk 7, with which the disk 5 is of course also set in motion. The disks can then be opened one after the other in the order h, j, 2, 1, so that the locking position shown in FIG. I is finally reached. All discs with the exception of disc 1 are pulled counterclockwise. If the disk 1 or the control disk 6 is secured by means of a pin engaging from the outside, they remain in place. other discs

2 - 5 in the locking position.

The release of the control disk 6 with the disk 1 is through causes the pin 16 or other locking devices, where si cli the disk 1 counterclockwise so far threatens until the guide curve 10 from the beginning to the end at Stop ti has passed and finally from the latter in the End. -; division.

Because the recesses 9 of the disk 1 and those of the disk 2 are now exactly opposite each other, the disk 2 is free, the SiChY ¹ and the other disks 3, h and 5, are rotated clockwise to the end of the guide curve 10. The disks 2 and 3 are now facing each other with their recesses 9, so that the rotary movement can begin for the disk 3 and then subsequently for the disks h and 5. Finally, the position in Fig. 3 and 4 is reached, in which the two control disks 6 and 7 with their recesses 15 are adjacent to one another in such a way that the shaft of the firing pin or ignition contact 18 engages the control disks 6 and 7 . pass and thus can reach and pierce the primer.

Due to the spring preload on all discs 1 to 5 the clock spring 12 ensures that this end position is maintained.

The flat design of the discs allows two or three packages can be arranged one above the other, but the release of the last slice of the last package is decisive is for the end of the upstream pipe safety or for the delay period after the bullet hit.

All information and characteristics disclosed in the documents, in particular the disclosed spatial training and structural design are - as far as they are compared to the state dor Technology, individually or in combination, are new - as essential to fulfillment claimed.
