RO121876B1 - Self-destructing contact fuze for submunitions (bomblets) - Google Patents

Abstract

The invention relates to a self-destructing contact fuse for submunitions (bomblets), designed especially for equipping the cargo -type projectiles, fired by guns, howitzers and gun-howitzers, for warfare components of rockets or thrower or air bombs. According to the invention, the fuse comprises a central striker (4), provided with a safety spring (5) with which a protective and security lid (1) is in contact, and also a mobile slider (8) having a motor spring (9) which may locate an ignition primer (6) into a main detonating circuit.

Description

The present invention relates to a self-destructing contact spot, for submunitions (bombs), intended to equip cargo projectiles, cannon shots, howitzers and cannons3 howitzers, missile combat components, launcher bombs, aviation bombs, etc.

Different types of self-destructing contact seals are known, which equip the submunitions (bombers) of cargo projectiles or combat components of rockets7 and which have a trigger, a spring-loaded trigger and held in a resting position by a system. ball indexing. When the trigger is released, it hits a staple, which activates the entire load.

The main disadvantage of these warheads is that they do not provide a high percentage of operation on contact or self-destruct, of submunitions. On the other hand, these warheads are intended to equip a certain strict category of ammunition: cargo-type artillery projectiles or submunition launcher bombs or submachine missile combat components or submunition aviation bombs.

The technical problem, which is solved by the invention, is to make a self-destruct contact focal point, for submunitions (bombs), that can equip them irrespective of the category of single-firing ammunition, so that it can replace the different construction rifles. , which are intended to equip certain categories of ammunition.

The self-destruct contact fire, for the submunitions (bombs), according to the invention, solves the proposed problem and removes the disadvantages above, by the fact that it can have a central safety arc trigger, which has the role of throwing a protective cap, at the time of submunition (bumblebee) evacuation, thereby allowing a movable arc-slider to position an ignition stopper in the main detonating circuit, and for initiating the self-destruct mechanism, the foci may have a movable-arc-triggered trigger in the structure. locking ball, an ignition box mounted in a fixed casing block, which are intended to initiate a pyrotechnic composition to delay the self-destruct mechanism27, and to ensure it in the unarmed position, during handling, transport and storage, used a rigid fuse, which can be removed in the motion of the submun load of the projectile (bomblet) in the projectile, whether it is: launcher bomb, rocket combat component, aviation bomb, etc. The contact fire, according to the invention, does not use external forces, which arise as a result of: firing / launching of artillery projectiles, launcher bombs, rockets, aviation bombs; evacuation of submunitions, etc., reinforcement and initiation of the self-destruct mechanism of the melee being realized exclusively on the basis of the energy of its elements.

The self-destruct contact fire, for the submunitions (bombs), according to the invention, has the following advantages:

- high degree of contact and self-destruct operation, ensured by the reinforcement and initiation of the self-destruct mechanism;

- the possibility of equipping with this type of outbreak, the submunitions (bombers) from the composition of several categories of ammunition: artillery projectiles, launcher bombs, missile fighting components, aviation bombs, etc.

The structure of the self-destruct contact focal point, for the submunitions (pumps), according to the invention, comprises: a contact operating mechanism, a mechanical system of 5 isolation of the ignition head of the main detonating circuit, a self-destruct mechanism, a protective cap 1 , a rigid fuse 2 and a stabilizing device 3. 7

The contact operating mechanism is composed of a central trigger 4, with a safety spring 5, an ignition staple 6 and a detonating staple 7. 9

The mechanical isolation system of the ignition cap of the main detonating circuit is composed of a movable slider 8 with a motor spring 9. This slider 8 contains an ignition stop 11 of the main detonating circuit 6 and the self-destruct mechanism.

The self-destruct mechanism of the bulb consists of a movable trigger 10 pressed by a spring 11 motor, a locking ball, a hole for inserting / releasing the locking ball 12, an ignition stopper mounted in a fixture block 13 and a composition 14 15 delay pyrotechnics. To ensure the protection of the pyrotechnic delay composition 14, a membrane is used 16. 17

The protective cover 1 and the rigid safety 2 have the role of ensuring the focus in the unarmed state, during handling, transport and storage. When introducing submunitions 19 (bomblets) with focal point in the projectile (launcher bomb, rocket combat component, aviation bomb, etc.), the rigid safety 2 is removed. 21

The ribbon stabilizing device 3 has the role of stabilizing the submunition (buzzer) with foci, from the moment of evacuation until the objective is reached. 2. 3

Until the moment the muzzle is assembled to the submunition (bomblet), the movable cursor 8 is additionally secured, with the help of a screw 15. 25

Operation of self-destruct contact fire, for submunitions (bombers): when evacuating submunitions (bombs) from the projectile (launcher bomb, missile component 27, rocket bomb, aviation bomb), the central trigger 4 under the action of safety spring 5 moves, removing the protective cover 1, thus releasing the movable slider 8 with spring 9 from the structure of the mechanical isolation system of the ignition cap of the main detonating circuit. Under the action of its arc, the cursor executes a displacement in plane 31 transversely, of the focos. At the end of this movement, the bulb is armed, the box 6 of ignition of the main detonating circuit being positioned under the central trigger 4. 33

With the reinforcement of the outbreak, the operation of the outbreak self-destruct mechanism is also initiated. Thus, the movable trigger 10 with the motor spring 11 of the structure of the self-destruct mechanism is released by its locking ball and initiates, by stinging, the ignition box of this mechanism. The gas and fire jet, resulting from the initiation of this staple, 37 produces the ignition of the composition 14 pyrotechnics of delay.

When the submunition (buzzer) is contacted with the objective, the operation mechanism at 39 contacts will produce the submunition (buzzer) operation. If the contact operation does not occur, after burning the delay composition 14 of the structure of the self-destruction mechanism, the gas and fire jet initiates the detonation box 7 of the muzzle. Thus, the submunition (buzzer) will work shortly after contact with the objective, due to the 43 self-destruct mechanism of the outbreak.

Throughout the fall of the submunition (bomblet), the "movement between the evacuation point and the objective", the stabilization device 3, mounted on the bulb, will ensure the stability of the submunition (bomblet) movement. 47
