Description

The technical solution relates to a thermobaric charge and a thermobaric reactive grenade for RPG-type hand grenade launchers and their modification, which contains a hollow body filled with active filling and equipped with a rocket motor and a cartridge.

BACKGROUND OF THE INVENTION

Cartridges and shells, or "ammunition", for hand-held anti-tank grenade launchers such as RPG-7, RPG-7V and RPG 75 are widespread in the world. They are used against tanks and armored vehicles, including lightly armored vehicles, against shelters, but also against relatively slow low-flying targets such as helicopters, aircraft with vertical take-offs, etc. These ammunition cartridges and shells use the known cumulative charge effect ) and the effect of detonation of the cumulative missile at the explosion site. In many countries, this weapon is used for its availability and relative ease of use and operation.

As a result of a change in the strategy of deploying military units, eg in international missions, there is an increasing need to deploy ammunition with increased pressure and inflammation, particularly against lightly armored targets, such as lightly armored vehicles equipped with modern electronic devices or against and reinforced concrete structures and natural bunkers in which potential enemies are hidden.

To meet these requirements, new and new types of weapons and ammunition are being developed, one of which is the so-called thermobaric ammunition. In this ammunition is used thermobaric explosive, which has up to more than double the pressure effect, which is also associated with an incendiary effect. The principle of a thermobaric explosive is the use of a high explosive and a mixture of metal powders, which together after ignition of a high explosive creates a so-called thermobaric effect.

Due to the manufacturing and service simplicity of the system for hand-held anti-tank grenade launchers (pancéřovek) such as RPG-7 and RPG-7 In some manufacturers of weapons produce shells and shells (missiles) for this type of weapon and instead of the classic cumulative charge, or grenade and grenade, specially redesigned with thermobaric charge on the basis of solid, liquid, respectively. gel explosive mixtures such as a GTB-7VS cartridge. In addition to the fact that such a newly designed cartridge or grenade (bullet) with thermobaric charge shows altered ballistics and flight characteristics, its use also requires changes in the weapons type RPG-7 and RPG-7 V, consisting primarily in the use of a new optical sight eg MG0-7VMU, which in combination with a new cartridge or grenade with different ballistics puts greater demands on the operation and handling of weapons.

The aim of the technical solution is to improve the utility properties of existing established cartridges and grenades for anti-tank weapons such as RPG-7, RPG-7V, RPG-75 and their modifications.

The essence of the technical solution

The object of the invention is achieved by thermobaric charge and thermobaric reactive grenade for RPG-type hand grenade launchers, which consists in that the body, rocket engine and kaj hub are delaborated parts of cumulative charge and grenade for RPG-type anti-tank hand grenade launchers. or the hub is filled with a thermobaric explosive and is closed from the front end by a front adapter with a central opening in which a head lighter is accommodated.

The principle of improvement is the laboratory of thermobaric explosives instead of the original explosives, designed to induce the penetrating effects of charges and shells. In general, the existing cumulative rounds PG-7V, PG-7VM and 68 Pr grenades for hand-held anti-tank grenade launchers type RPG and RPG-1 CZ 25331 Ul are optimally designed according to the type for anti-tank and armored technology. extremely advantageous to fully utilize at least some of its design elements to create a thermobaric charge and grenade according to the present invention, while retaining all the advantages of the charge, grenade and handheld anti-tank grenade launcher type RPG and RPG-75 such as ease of use and handling; characteristics and ballistics, the possibility of using existing launchers without the slightest modification and to gain new advantages in the form of essentially universal charge and grenade of domestic origin usable against both armored technology and against hardened places such as machine gun nests, bunkers, p Natural caps, caves and other areas with the appearance of a human enemy forces on a limited ru simplicity. With the use of elements of existing cumulative charges and grenades and elements of the existing hand-held anti-tank grenade launcher type RPG is associated with considerable financial savings compared to the simple disposal of existing cumulative charges and grenades and purchase a brand new thermobaric charge. At the same time, in the manufacture of the thermobaric charge and the grenade according to this technical solution, the original dust charge of the rocket engine is revised and thus the lifetime of this type of ammunition is extended.

Clarification of drawings

The technical solution is schematically shown in the drawings, where Fig. 1 shows a longitudinal section of an existing cartridge PG-7V, PG-7VM (state of the art), Fig. 2 a longitudinal section of a thermobaric cartridge warhead according to the technical solution; technical solution including rocket engine and cartridge.

Examples of technical solutions

Thermobaric reactive charge and grenade for hand grenade launchers type RPG7, RPG-7V and RPG-75 and their modification contains a hollow body 1, which is filled with a thermobaric explosive 2. The body 1 is preferably identical to the body of the existing cumulative charge PG-7V and PG- 7VM. Thermobaric explosive 2 is for example a mixture of Hx, TNT, Al and binder, which is homogeneous and after tempering it is pressed under a hydraulic press.

At its front end, the cavity of the body 1 is closed, for example by screwing, through a front adapter 4 with a central hole in which it is accommodated, for example screwing, a head lighter 3 which protrudes with its front part in front of the adapter 4 and its rear part is in contact or in the vicinity of a thermobaric explosive charge 2. The head lighter 3 is, for example, a GO-2, FTM-1, VMG, or similar lighter. These types of lighters initiate a thermobaric explosive in the body, even at any angle of incidence, including the so-called "flat" target. The adapter 4 and the head lighter 3 may be treated with a substance to prevent air humidity entering the cavity of the body 1, i.e. the thermobaric explosive 2, before being screwed into the hub body 1.

At the rear of the body 1 is mounted rocket engine 5, at the end of which is arranged cartridge 6 for ignition of the rocket engine 5 by launching mechanism in the existing barrel anti-tank grenade launcher type RPG. The rocket motor 5 and the cartridge 6 are preferably the same as the rocket motor and cartridge of the prior art, i.e. the cumulative charges PG-7V and PG-7VM.

Rocket engine 5 and cartridge 6 ensure trouble-free applicability of the thermobaric charge according to this technical solution with the existing and unmodified launchers of the main hand grenade launcher RPG-7 and RPG-7V. Thermobaric explosive charge body 2, with front adapter 4 and head lighter 3 has parameters equal to or close to the cumulative charge of PG-7V and PG-7VM, so that the flight characteristics and ballistics of the thermobaric charge according to the present invention are identical to flight characteristics and ballistics cumulative charges PG-7V and PG-7VM, which allows seamless use of the existing optical sight used PGO-7 or PGO-7V on the existing barrel anti-tank grenade launcher RPG-7 and RPG-7V.

Thermobaric cartridges and grenades for hand-held anti-tank grenade launchers type RPG can be manufactured and fitted with self-destruction, ie self-destruct system using the bottom parts of lighters such as VP-7, z-75, or. VD-1 bottom lighter and lighters of similar characteristics, which is stored in the rear of the cartridge or grenade.

Thermobaric charge for hand-held anti-tank grenade launchers type RPG according to the proposed technical solution has a caliber in the head part of 72 mm and is designed especially for hand-held anti-tank grenade launcher RPG-7 and RPG-7V caliber 40 mm. This technical solution is also applicable to the caliber in the head of the hub 85 mm and 68 mm grenade for hand-held anti-tank grenade launcher RPG-75.

An exemplary process for producing a thermobaric charge or grenade according to this technical solution is to take the existing known cumulative charge, eg PG-7VM, from whose body it delaborates, i.e. removes, the cumulative charge, ie the explosive, the spacer along with bottom and overhead lighter. The thus formed cavity of the body 1 is cleaned and then a thermobaric explosive is worked into it. Then, the body 1 is closed by the adapter 4 and the head lighter 3 and the hub, respectively. the grenade is ready for use or for packaging and shipping.

Basic TTP of thermobaric charge according to given technical solution are:

Parameter TB Caliber 72 mm Weight warhead 1,21 kg Hostnost bullets 2,25 kg Effective shooting distance 200 m Maximum shooting distance 900m Initial speed 66 mps Deadly radius quarry Wounding radius 50 m
