BG66695B1 - Thermobaric warhead - Google Patents

Abstract

The thermobaric warhead is constituent part of various ammunition and is intended for destruction of manpower, located in the open field or in shelters, also for destruction of engineering equipment, buildings and unarmored technique with the force of shock wave and high temperature. With the warhead is achieved higher efficiency in combat against manpower, located behind a partition or in a shelter, resistant to striking impact of fragmentation warheads. The thermobaric warhead is composed of thin-walled housing (1) of light metal alloy, in which are housed thermobaric composition (2) and the bursting charge (3), locked with a lid (4), to which is threaded detonator (6). The thermobaric composition is a solid heterogeneous composition of highly-dispersible metallic powders with oxygen-containing salts of inorganic acids, a high energy component of one or more high explosive compounds and binder of liquid rubbers with plasticizers, providing a uniform density throughout the occupied volume. The bursting charge (3) is positioned on the axis of the housing (1), directly into thermobaric composition (2) and is pressed axially by detonator (6) by means of at least one ring-shaped sealant (5).

Description

Field of technology

The invention relates to a thermobaric warhead included in various ammunition, which is used to strike manpower located in the open, in field shelters, engineering facilities, buildings and unarmored equipment, using a shock wave and high temperature.

BACKGROUND OF THE INVENTION

A mine with a thermobaric warhead is known. The characteristic feature of this construction is that the warhead consists of a body full of thermobaric mixture, closed by a head with a built-in pressure compensator. A transfer charge located in the thermobaric mixture is mounted to the head on one side and a fuse is wound on the other side [1].

A single-use ampoule grenade launcher grenade is known. Characteristic of this construction is that the warhead is equipped with a multicomponent thermobaric mixture, each component having a different density. When the ammunition is stored, the components are separated, the mixture expands and contracts. The thermal expansion of the mixture is compensated by the empty volume left in the ampoule [2].

A shot with a thermobaric grenade for a sub-barrel grenade launcher is known. Characteristic of this construction is the presence of a thin-walled body with a thermobaric mixture and increased striking effect of the shock wave (http://www.niiph.com/production/specprod/fireshots VG-40TB).

A hand grenade with a plastic body, equipped with a thermobaric mixture, is known. Characteristic of this construction is the absence of striking elements and a strong striking effect of the shock wave up to 7 m (http://www.niiph.com/production/specprod/Qrenades RG-60TB).

Technical essence of the invention

The object of the invention is to provide a thermobaric warhead with increased shock wave action and high manufacturability.

The problem is solved by creating a thermobaric warhead, consisting of a thin-walled body of light metal alloy, which houses a thermobaric composition, a solid heterogeneous composition of highly dispersed metal powders, acidic to salts containing inorganic acids, a high-energy component or several high explosives, a liquid rubber binder with plasticizers and an explosive charge directly adjacent to it. The housing with the thermobaric composition is closed by a lid to which a fuse is attached by means of a thread, pressing the explosive charge by means of annular seals.

The advantages of the invention are:

- said thermobaric composition is a heterogeneous composition with the same density over the entire occupied volume and together with the bursting charge provides a high striking effect of the shock wave;

- there is no stratification of the components, due to which the need for compensating elements is eliminated, which ensures stable flight of rotating and non-rotating ammunition and high operational stability;

- the explosive charge is placed along the axis of the ammunition, directly in the thermobaric composition, which increases the manufacturability, as there is no need for a detonator cup or chamber for its placement.

Examples of the invention

Thermobaric warhead different variants (figures 1, 2, 3, 4, 5, 6 and 7) consists of a thin-walled body 1 of light metal alloy, which houses a thermobaric composition 2 with directly located in it bursting charge 3. The body with the thermobaric composition is closed by a lid 4, to which a fuse 6 is connected by means of a thread, including a detonator 7 and pressing the bursting charge in the axial direction by means of annular seals 5.

Way of acting

The principle of operation of the different warhead options (figures 1, 2, 3, 4, 5, 6 and 7) is as follows.

After activation of the detonator 6 by impact in a barrier or expiration of the delay time, the detonator 7 is initiated. The detonation impulse 3 is detonated from the detonation pulse of the detonator, after which the formed explosion products disperse the thermobaric composition 2 , in which the products of the explosion of the aerosol cloud form a shock wave.
