Description

The invention relates to the field of armament, and in particular to aviation cluster-container systems in equipment with self-dispersing (rotating) combat elements.

As is known from the patent and technical literature, the effectiveness of destruction of bad targets largely depends on the area of the dispersion zone of the ammunition and on the specific efficiency of both the cluster-container system and the ammunition (warhead) itself.

In most cases, to disperse combat elements from cluster-container systems, sufficiently powerful explosive charges are used, which entails the forced hardening and weighting of the design of the spread elements. This leads to irrational use of the mass of cassettes and a decrease in efficiency.

An increase in the specific effectiveness of cluster-container systems can be achieved by using self-dispersing warheads for their equipment and by using an obturator-type unpacking system that does not require powerful explosive charges.

A known design of a non-rotating projectile with submunitions in flight (US Patent No. 843011 of 04.25.2001).

The cluster shell provides the placement and shooting of multiple submunitions and contains a cylindrical body, on the inner surface of which in the submunition deployment area spiral cuts are made. Submunitions are installed in the housing using a partition. The partition contains elements that engage with the grooves of the housing. When unpacking, partitions under the action of a buoyant charge move along the cuts of the case. The linear movement of the partition causes its rotation, while the torque is transmitted to the submunitions, which allows them to evenly cover the target of a given area.

Although the technical solution provided provides the required dispersion zone for submunitions without the use of powerful explosive charges, it has a number of significant drawbacks:

- the complexity of the design (spiral grooves on the case, mating elements on the partition, elements for attaching submunitions in the partition);

- low specific efficiency (the ratio of the mass of submunitions to the total mass of a cluster shell) due to the need to increase the thickness of the walls of the shell to make rifling and reduce the volume of submunitions due to the volume of the partition.

A known design of an aircraft bomb with sequentially fired striking elements (US Patent No. 3611931 from 12/10/1971 - prototype).

Aircraft bomb cluster consists of a cylindrical body and a series of blocks of combat elements inserted into each other and held in assembled position by means of screws. Blocks are assembled in sections that are joined by welding. The fuse is installed at the junction of the sections, fire-resistant cords laid in aluminum pipes depart from it. In addition, each unit is equipped with a baffle platform with a powder mount, which serves to eject combat elements from the cartridge case. The cavities in which the powder hinges are placed are connected using flame tubes. When the fuse is activated, the force of the flame is transmitted to the fire-resistant cords and then to the powder hinge.

Under the influence of powder gases, the knockout platform, cutting off the fixing screws, ejects the combat elements from the extreme blocks, then from the following, etc. With a free fall, the dispersion of combat elements occurs.

The disadvantages of this technical solution include:

- low specific effectiveness of the cartridge due to the impossibility of placing combat elements in the space under the fairing (ejection of blocks of combat elements is possible only from the cylindrical body of the cartridge);

- low reliability due to the large number of elements in the firing circuit of the cartridge and the sequence of their operation;

- the safety of bombing is not ensured because of the possibility of a “leakage” of powder gases from one knockout platform to another, bypassing the fire cords (absence of obturation elements on the knockout platforms).

The task of the invention is to increase the effectiveness of a single bomb cartridge.

The technical result consists in increasing the specific efficiency (the ratio of the mass of combat elements to the total mass of the cartridge), safety and reliability of the cartridge.

The technical result is achieved by the fact that a single bomb cluster includes a housing, a gas generator and a frame in the form of front and rear flanges, between which rotary warheads are placed in transverse rows separated by disks, while it is equipped with a central tube and a piston device made in the form of a cylinder conical cover with a sealing ring on a cylindrical part, spaced and exhaust element connected to the front flange, equipped with coaxially placed and rigidly connected reflector and a cylindrical sleeve connected to the Central tube by a tube, and the gas generator is placed in the cavity of the Central pipe from the side of its front end.

Increasing the specific efficiency of the cartridge while maintaining its dimensions and mass is achieved by:

- increasing the number of combat elements placed in the cartridge (combat elements are placed both in the cylindrical and animated parts of the body due to the implementation of a piston device with a cylindrical-conical shape with a sealing ring on the cylindrical part and the cartridge case of a cylinder-animated shape);

- obturator principle of removing the cartridge case, which is provided by supplying the cartridge with a piston device and connecting the structural elements with a central pipe, cylindrical sleeve and tube and does not require powerful explosive charges, and therefore can significantly reduce the mass characteristics of the body parts of the cartridge and combat elements, while mass is used to compensate for the mass of combat elements placed in the animated part of the hull.

Improving the safety and reliability of the cartridge is achieved by:

- use of a single gas generator located in the cavity of the central pipe from the front end side to remove the cartridge case from the frame and piston device from the front rows of combat elements located in the animated part of the body;

- supplying the front flange with a reflector, eliminating the possibility of destruction of the exhaust element when ejecting a plug connecting the cylindrical sleeve to the Central pipe.

In a single bomb cartridge, the front flange can be rigidly connected to the fairing and the cartridge case, which is made of a cylinder-animated shape, which will allow:

- reduce the length of the fairing while maintaining the aerodynamic characteristics of the cartridge, and therefore, increase the specific efficiency of the cartridge;

- increase the number of combat elements placed in the cartridge while maintaining overall mass characteristics.

In a single bomb cluster, the carcass disks can be made of sectors, each of which is equipped with seats for combat elements and a tide along one of its faces, and a response nest on the other, which will significantly increase the reliability of the cartridge’s operation (simultaneous and unhindered entry of military elements into the air stream).

The possibility of industrial application is due to the specific implementation of the invention, characterized by the following structural scheme.

Figure 1 shows a General view of a single bomb bomb.

Figure 2 shows the frame with a front flange.

Figure 3 shows a gas generator.

Figure 4 shows a sector of the disk.

A single bomb cluster consists of a housing 1, a frame 2, a gas generator 3, a front 4 and a rear 5 flanges, combat elements 6, disks 7, a cylinder-conical cover 8 with an o-ring 9, a central pipe 10, a cylindrical sleeve 11, a plug 12, an exhaust element 13, the reflector 14. The disk 7 consists of sectors 15, equipped with tides 16, sockets 17 and seats 18 for combat elements.

The operation of a single bomb cluster is as follows.

After a predetermined period of time after separation of the cartridge from the carrier, the gas generator 3 is activated. Under the action of the pressure of the products of combustion of the gas generator 3, the plug 12 flies into the cavity bounded by the cylindrical sleeve 11 and the reflector 14, thereby breaking the connection of the cylindrical sleeve 11 with the central pipe 10. Combustion products of the gas generator through a vacant hole flow into a cavity bounded by the animating part of the housing 1, the cover 8 and the front flange 4. Under the influence of pressure, the products of combustion of gas lighter 3 in the indicated cavity, the cassette 1 comes off the frame 2, while the front flange 4, the reflector 14, the sleeve 11 separate with it, and when the housing 1 is completely gone and the exhaust element 13 is pulled from the central pipe 10, the cover 8 with the o-ring is removed 9. The combat elements 6 and sectors 15 of the disks 7 freed from axial preloading under the influence of the incoming air flow fly apart in radial directions relative to the central tube 10.

When the combat elements 6 meet with an obstacle, their fuses are fired and the warheads are undermined. The fragments resulting from the detonation of warheads cause damage to the target.

The operability of the proposed design of a single-shot bomb cluster in equipment with self-scattering fragmentation warheads is confirmed by design and experimental tests in ground and flight conditions.
