SK500202019A3 - Deactivation device for explosion-proof disposal of pipe bombs and method of placement to pipe bomb - Google Patents

Abstract

The device consists of a plastic explosive (1), a casing (2), a detonator (3) and a holder (4) made of wire enabling positioning against a pipe bomb. A suitable geometry of the plastic explosive (1) placed in the package (2) will perform a directed flow of energy after initiation by the detonator (3), whereby the closure of the tube bomb will be torn off. Depending on the geometry of the cavity in the plastic explosive (1), it is possible, in addition to creating a cumulative piercing beam, also to create a hammering effect which has a surface effect. The sharper the apex angle of the cavity in the plastic explosive (1), the more pronounced the beam and the smaller the surface action. The invention can be used in the disposal of booby-trapped explosive devices in such a way that they do not explode, whereby a subsequent forensic examination of the components of the booby-trapped explosive devices to detect traces left by the perpetrator is possible.

Description

Technical field

The invention relates to the non-explosive disposal of booby-trapped explosive systems which are constructed in the form of tubular cones. The invention can be included in the field of ammunition and work with explosives.

Prior art

Booby-trapped explosive devices (NVZs), including pipe bombs, are constructed mainly of packaging, explosive and initiator. The casing of the tube bomb is formed by a metal tube with screw-on caps at the ends. As the explosive, military, industrial, home-made explosives, black powder, pyrotechnic composition and the like can be used. Different sources can be used as initiators depending on the explosive used. Depending on the required consequence, the extent of the damage, the individual parts of the NVZ are selected. Disposal of NVZ is currently carried out depending on the size of NVZ, the place of storage of NVZ, destructive, non-destructive gradual and appropriate equipment. The procedures and equipment used today are the firing of the NVZ with a water jet, a shotgun, the application of an explosive to the NVZ and the realization of a controlled explosion. In the case of tube bombs, shotgun and water jet firing is ineffective and the application of an explosive will cause the tube bomb to explode, destroying all traces left by the perpetrator and consequently damaging property in the explosion area. Products using the accumulation of a water jet by explosion are available on the market for the required purposes of disposal of NVZ in automobiles.

The geometry of the explosive which produces the desired effects for the destruction of the tube bomb, without the metal insert for creating the piercing effect which is the subject of the invention, has not been published.

The essence of the invention

To work with explosives, it is necessary to choose such explosives that the person manipulating the nina and the god usable for the chosen goal are not endangered. For the construction of a deactivation device for explosion-proof disposal of tubular bombs, it is necessary to use an explosive with a detonation velocity greater than 6,500 m / sec., Which creates a sufficient directed effect with a suitable geometry of this plastic explosive and its location relative to the NVZ.

The object of the invention is to provide the desired geometry of a plastic explosive which, after initiation by the detonator, performs a directed flow of energy and the subsequent perforation of the tubular bomb and the removal of the closure. Geometric geometry treatment of an explosive is the concentration of gas flow energy after an explosion, which is caused by the geometry of the cavity in the mass of this explosive. The pressure wave caused by the explosion tends to copy the surface of the explosive, thereby concentrating in the focus of its cavity and creating a beam of gases with the velocity and parameters of the created beam geometry. Depending on the geometry of the cavity, it is possible to create a second effect, i.e. in addition to creating a cumulative piercing beam. j. hammering effect, which has a surface effect. The sharper the apex angle of the cavity in the plastic explosive, the more pronounced the beam and the smaller the surface action. The cavity may be in the shape of a hemisphere, a hyperboloid, a cone with a vertex in the oscillator of a deactivation device for disposing of tubular bombs.

To increase the penetration effect, the surface of the cavity can be reinforced with a copper, steel, bronze element, which has an effect on the parameters of the generated beam. In our design at explosive speeds above 6,500 m / sec. for the purpose of disposing of a tubular bomb, there is no post-traction insert.

Advantages of the invention:

• portable, small device, improvised manufacturable instead of finding a pipe bomb, • using a stable, industrially produced plastic explosive with the required parameters can be prepared anywhere and anytime, • guiding the piercing beam and hammer is without the use of a metal insert, • non-explosive deactivation of the tube bomb crinrinalist tracks left by the perpetrator on the deactivated tube bomb components.

Disadvantages of the invention:

• for handling explosives it is necessary to have knowledge, skills and understanding of the explosives used. For the deactivation device for the disposal of pipe bombs, it is suitable to use an industrially produced plastic explosive with thermal and chemical stability, • to use an explosive with a minimum detonation speed of 6500 m / sec.

Examples of embodiments of the invention

Example 1

The deactivation device for non-explosive disposal of tubular bombs consists of a plastic explosive 1, a casing 2, a detonator 3 and a wire holder 4. The plastic explosive 1 is formed by a cylinder most preferably with a base of 30 mm and a height of 60 mm, on the underside of the cylinder with a cone starting at the lower edge of the cylinder most preferably at an apex angle of 70 degrees and at the upper edge ending at a cone most preferably at an apex angle of 70 degrees. At a height / length ratio of 2: 1 of the plastic explosive cylinder 1, the greatest piercing effect is achieved. A preferred embodiment can also be a plastic explosive 1 formed on the underside of the cylinder with a cone starting at the lower edge of the cylinder with an apex angle of 65-75 degrees and at the upper edge ending with a cone with an apex angle of 65-75 degrees. For the construction of a deactivation device for the non-explosive disposal of tubular bombs, an explosive with a detonation velocity greater than 6,500 m / sec, e.g. Semtex-1A with a detonation velocity of 7,200 m / sec. The package 2 is made of plastic, e.g. polyethylene with a thickness of 2 mm and describes the external shape of the plastic explosive 1. In the package 2 there is an opening on the upper side for axially central insertion of the detonator 3. The package 2 is equipped for positioning relative to the NVZ with a wire holder 4 which can be bent for the desired position relative to the NVZ.
