Description

The invention relates to the field of military equipment, in particular to incendiary bombs designed to destroy industrial, city, warehouse buildings and other similar objects with fire.

Known aerial bomb with the release of incendiary matter through the tail (US Patent No. 2741177 dated 04/10/56, NKI 102-6).

The bomb consists of a steel case filled with incendiary substance in a gauze bag, an explosive device, an ignition-blow charge and a belt stabilizer. After hitting an obstacle, an explosive device is triggered, which initiates an ignition-blow charge. The pressure of the products of combustion of the charge ignites a substance that ignites and is ejected as a single burning element through the tail of the bomb. The disadvantages of this design include the low efficiency of the action, since it only requires a direct hit on the target (there is no crushing of incendiary substance into a large number of elements and the dispersion of elements in the area).

A device for the formation of an artificial fire curtain according to the patent of Germany No. 1913790 from 03.19.69, NKI 72d 19/02.

The device is a warhead, which consists of upper and lower parts connected by a shell. A calibrated jumper is located between both parts. In the upper part there is a fuse, to which a tube with an igniter charge is connected, passing through the entire warhead. Stacked stacked elements with incendiary composition. The tube has a calibrated jumper and holes through which the incendiary composition of the elements is ignited.

Unpacking the warhead occurs at an altitude of about 400 m. The fuse initiates an igniter charge. From the pressure and temperature created by the igniter charge, the calibrated jumpers are destroyed, the incendiary composition of the elements is subsequently ignited and expelled from the shell.

The disadvantages of this technical solution include:

- design complexity;

- low reliability;

- the impossibility of defeating industrial buildings (only the creation of a fire curtain);

- significant energy losses during the autonomous movement of elements with incendiary composition.

A known design of incendiary bombs, including a warhead (warhead), which contains a housing, incendiary and igniter compositions, a device for crushing and dispersing incendiary composition (Application of France No. 2684178 from 26.11.91, F 42 B 12 / 44,15 / 00 - prototype).

Incendiary and igniter compositions are placed adjacent to the warhead unit, each in its own compartment, and the device for crushing and dispersing the compositions (bursting charge) is placed in the shell along the axis of the warhead case and consists of three elongated detonating charges (DLD). The compartments in the warhead housing are separated from each other by partitions.

The technical solution to this application, although it provides a crushing of incendiary and igniter compositions into individual elements with their subsequent spread in the area, but has several disadvantages:

1. Low reliability of ignition of the incendiary composition, since the adjacent arrangement of igniter and incendiary compositions in the warhead housing does not allow for uniform distribution of the ignition composition in the volume of incendiary composition dispersed from the operation of remote sensing systems.

2. Uneven distribution of incendiary and igniter composition over the area, which leads to a decrease in the effectiveness of the action of the bomb. Due to the fact that when the remote sensing system is activated, the warhead unit is divided into three sector parts, the maximum range of the elements of incendiary and igniter compositions will be provided along the division lines of the case, and the bulk of the compositions will be located near the point of impact of the bomb.

3. The low filling factor of the bomb due to the lack of incendiary and igniter compositions in the area of the stabilizing device.

4. The impossibility of separate storage of warhead elements, which leads to the need to increase the requirements for the tightness of an air bomb and requires the creation of large dimensions of special storage facilities (the cost of operating an air bomb)

The task of the invention is to increase the effectiveness of aircraft incendiary munitions and reduce the cost of its operation.

The technical result consists in increasing the reliability of ignition of the incendiary composition and its uniform distribution over the area while increasing the fill factor of the aircraft incendiary munition. An additional technical result achieved during the implementation of the invention is to provide the possibility of separate storage of pyrotechnic elements and the explosive charge of the bomb.

The technical result is achieved by the fact that the incendiary bomb contains a housing, fuse, incendiary and igniter compositions, a bursting charge, while the housing is made in the form of a cylindrical conical shell rigidly connected to the sleeve in the form of a glass, in the cavity of which the igniter composition adjacent to the sleeve is coaxially placed and explosive charge, and in the cavity between the shell of the housing and the sleeve placed incendiary composition.

Improving the reliability of ignition of the incendiary composition and its uniform distribution over the area is ensured by the axisymmetric placement of the explosive charge, igniter and incendiary compositions in the body of the bomb, which leads to:

- preliminary crushing of incendiary and igniter compositions by detonation products of a bursting charge until the destruction of the body of the bomb;

- further crushing and mixing of pre-crushed compositions at the time of dispersion during the destruction of the body of the bomb;

- crushing the bomb shell by detonation products of a bursting charge into many fragments that do not impede the uniform crushing of incendiary and igniter compositions and their thorough mixing.

The increase in the filling factor of the bomb is achieved by making the shell of the bomb in the form of a cylinder-conical shell, which allows the cavity of the conical part of the shell, on the outer surface of which a stabilizing device is placed, to be used for additional placement of incendiary composition.

The igniter composition can be placed in the cavity formed by two axisymmetric rigidly connected cylindrical shells, and the bursting charge is placed in the shell in the form of a two-stage cylinder.

The placement of the igniter composition and explosive charge in their own shells can significantly reduce the cost of operating an incendiary bomb due to the possibility of separate storage of the bomb shell with incendiary composition, igniter composition and explosive charge in sealed packages. Separate storage of component parts of an aerial bomb does not require the construction of special storage rooms of large dimensions, since, in this case, the body of an aerial bomb with incendiary composition can be stored in ordinary storage rooms or in an open area under a canopy, and ignition composition and explosive charge can be stored in special rooms of small dimensions.

The assembly of an incendiary aircraft bomb will be carried out at the airport when it is suspended on a carrier holder.

The explosive charge can be made in the form of a set of explosive pieces, which ensures that when it is fired, the bomb body is destroyed into many fragments that do not impede the uniform distribution of elements of the incendiary composition over the area.

Figure 1 shows an incendiary aircraft bomb.

Figure 2 shows the igniter composition.

Incendiary bomb includes a fuse 1, a shell in the form of a shell 2 and a sleeve 3, an incendiary composition 4, a stabilizer 5, an ignition composition 6 in the shell 7, an explosive charge in the form of checkers 8, placed in the shell 9 and having a cavity 10.

Incendiary aerial bomb works as follows.

When you hit a bomb about an obstacle fuse 1 fires, which initiates the explosive charge checkers 8. Under the action of detonation products of a bursting charge, a bomb body is destroyed, dispersing and mixing elements of igniter 6 and incendiary 4 compositions. Elements of an igniting composition spontaneously ignite in air and ignite elements of an incendiary composition in the form of separate foci, falling on flammable objects, ignite them.

The use of the proposed technical solutions in an incendiary bomb significantly increases its effectiveness and reduces the cost of its operation.
