The invention relates to military technology, and is intended to conserve materials and energy extracorporeal shock-wave impact on various substances and objects, in particular engineering ammunition, explosives and manpower of the enemy.

The well-known problems associated with the necessity of small means, with safe disposal, reliably incapacitate people and equipment. As one of the universal methods of destruction has long been successfully applied shock waves that occur after the detonation of explosives (hereinafter CC). They burn and destroy material objects, initiate undermining ammunition and instantly inhibit the normal functioning of biological objects.

A disadvantage of conventional methods of application of the shock waves is the high cost of the procedure. To measure the scale of damage in a real combat situation difficult. Selectively destroy only the basis of the enemy war machine (and ammunition), and saving in this case is dangerous. In the end, the costs incurred and the final damage is many times greater than the useful effect. Powerful explosions destroy everything.

Race conventional weapons has led to a paradoxical result. Beyond the fire power of modern military equipment is still inadequate. As a hundred years ago, it's not enough for 100% destroying the Oia located in simple trenches, right under the open sky soldier, lying on the mind of ammunition, as well as mine barriers, unless, of course, is not to set goals to transform the area in the scorched desert.

Theoretically, it is known that the same result (detonation of the explosive charge causing serious injury) in relation to the main elements of the modern armed forces can be achieved by acting on target once powerful shock wave, or repeated action on it a few much more weak shock waves. On material and energy costs last option is hundreds of times more profitable. People and explosive objects are destroyed, and material values are stored.

The probability of an exact match of power and repetition frequency random shock waves with resonant properties of specific targets in real combat small. However, consider, for example, in the recommended standards for maximum density mining, as well as when used for high-clearance areas and destruction of enemy forces, massive explosions of the fuel-air mixtures. In its pure form, the above effect is observed rarely and irregularly.

It is known that exactly according to the power and frequency of elastic waves, with the characteristics of the voice of the subject and acoustic impedance intermediate environment, it is possible to achieve mechanical is about destruction or initiate chemical reactions. To this kind of attack is especially sensitive biological objects and explosives. The required result is reached when the cost of energy is many times smaller than would be required in the case of a single mechanical shock or simple heating. (Focusing of sound and ultrasonic waves. Intumesce, Monograph. - M., Nauka, 1977. - 336 S., ill., 324 PP-329).

Direct use of ultrasound in combat conditions, for remote destruction of manpower and engineering ammunition is technically impossible. Required mechanical contact between the emitter and the target. Real environment (air, normal water, various soils), through which must be distributed elastic vibrations, does not provide long-distance transmission of power, sufficient for effective impact. Particularly strong attenuation of ultrasound in a humid atmosphere.

To solve this, we need a way of combining long-range energy transfer in real environments (typical of normal shock waves), with the ability to control their power and repetition rate (typical for normal sound emitters).

For the prototype accepted method of application to a specified destination of a series of shock waves that occur when a single explosion in the self-oscillatory process. Effect of crushing on a portion of the energy of the explosive gases and the e output in the surrounding space as a sequence of shock-wave fronts reach the selection of the optimal relationship of the density of the explosive charge and the density of the substance to the environment.

A method of obtaining stretched over time, the pulsation of the gas cavity of detonation products after the explosion of fuel-air explosive munitions. Striking effect of this explosion is significantly higher than the charge dense explosives equal power. (Physics of explosion / Under. edit Lupolenko, 2 so, 1. - M.: FIZMATLIT, 2004.- 832 C., Il. str).

Known oscillatory process (ripple gas cavity), when one explosive charge creates a series (5-10 or more) consecutive shock waves observed during underwater explosions. Its damaging effect of such waves also significantly higher than in the case of a single shock wave, carrying the same energy. (Physics of explosion / Under. edit Lupolenko, 2 so, 1 - M.: FIZMATLIT, 2004. - 832 C., Il. str-614).

Use the principle of dividing the kinetic energy at the moment of elastic material impact phone At the contact interface explosive gases with a neutral environment surrounding the epicenter, is an exchange of momentum. After hitting high speed and a large share of energy acquires a body with less mass. If the density of matter in the area occupied by the products of detonation, significantly lower than the density of the environment, part of the explosion energy (up to 50%) is returned.

Occurs aperiodic oscillatory process. Spherical shock wave radiating out from the epicenter of the explosion, on the border of the div is La environments is reflected and becomes convergent. The cycle repeats. All the energy of the explosion is transmitted to the environment after several consecutive pulses, in the form of a series of weakening the shock waves of variable frequency.

The characteristics of the prototype, coinciding with the essential features of the claimed invention: the impact of substances and objects carried out by a series of successive shock waves. The strength and frequency of these waves is changed. These factors when matching the resonant characteristics of the target reinforce useful striking effect of a single explosion.

Barriers to obtaining the required technical result of the prototype: generating a shock wave device is destroyed in the explosion and is used only once. The process of generating the oscillatory and not amenable to surgical management. The strength and frequency of shock waves in complex ways dependent on each other, from the explosion parameters and physical properties of the environment. The process is not predictable, it is influenced by many factors. Generating high frequency shock waves thus impossible.

The technical result of the application of the method

The best in comparison with single shock waves affecting effect and lower material and energy costs when exposed to various substances and objects, remote initiating det the nation explosives or contactless defeat of living organisms. Full management of significant process parameters.

The method is simple, predictable results and versatility. It allows you to convert factor affecting not only thermal energy pyrotechnic origin, but also energy from electrical or mechanical source of sufficient power.

The technical result is achieved in the following way: all the significant parameters of the exposure control. Generating shock waves of arbitrary length (short series about 3-10 pulses to continuous), arbitrary frequencies (from infrasound to ultrasound) and arbitrary power (within the capacity of the radiator). The energy transferred by a series of shock waves, in contrast to harmonic oscillations, does not limit the sound impedance of the propagation medium. This allows you to precisely align the nature of the impact to the physical properties of a specific remote target.

The essential features of the claimed inventions

As a means of influencing substances and objects used shock wave. The effect produced by a series of successive shock waves. The duration of the impact force of each shock wave and the frequency of their repetition is administered so that they reflect optimal for the task at hand meant the pits.

Unlike the prototype, the duration of a series of shock waves, the strength of each wave and the frequency of their repetition are not mutually dependent quantities. Each of the listed parameters can be set and operative to change separately from the rest.

The influence of the essential features of the claimed invention to obtain a technical effect

The greater the distance between the wave generator and an object of exposure, the stronger the effect on the process of transmission of wave energy separating their environment. Sound impedance of atmospheric air or soil greatly limits the power of the transmitted harmonic oscillations, if the frequency range beyond certain limits. The shock waves this restriction does not apply. Each of them is moving independently from the rest. A series of shock waves allows, for example, to transmit a powerful pressure pulses of ultrasonic frequency through the air, where conventional ultrasound quickly fades.

Every material object has a certain resonance properties. Long enough acting on any subject to shock waves of the right frequency and power, you can make it resonant oscillations to cause mechanical destruction or to provoke a chemical reaction, such as the detonation of the explosive charge. P is lny energy consumption to obtain the above result is much less than when using a single shock wave high power.

If the physical properties of the object of exposure is not known in advance exactly what the optimal frequency and strength of shock waves can pick up, smoothly changing their settings to get the result or periodically rearranging the generation mode according to a certain program. The same method is suitable for simultaneous and independent processing of the group of objects different from each other physical characteristics.

The method is not characteristic of conventional weapons selectivity. If the parameters of the series of shock waves (frequency, power, duration) does not correspond to the resonant characteristics of the object of exposure, their destructive effect is weak or missing. For example, the procedure of the continuous scanning of the road in front of a moving vehicle by a series of shock waves that are configured to initiate detonation of ammunition engineering, 't hurt gravel and underground utilities. The funnel will be only from explosions and only where it's really laid mines.

If continuously to generate a shock wave constant force and frequency, at a repetition frequency higher than 25-30 kHz (ultrasonic range) you can make them completely safe for the environment. Even slowing down, shock waves is transformed into sound, and ultrasonic vibrations in the air quickly extinguished. Thus, a continuous stream of shock waves at a distance of 5-10 m causing the detonation of the ammunition engineering, at a distance of 40-50 m will merge into a solid high frequency whistle, and from a distance of 100-150 m will not be noticeable at all.

The resonant excitation process does not require large expenditures of energy. Weakness serial shock waves compensated for their rational use. Destructive action of the waves on the structural elements of the generator can be minimized. This allows to create a wide variety of devices as disposable (exploding), and capable of long continuous operation. Compared with conventional methods of obtaining a shock wave that expands the range of applications and provides economical consumption of material resources.

Examples of carrying out the invention

1. Resonant anti-personnel mine disposable steps

In the atmosphere of the fatal defeat of the human body is 99% guaranteed under the action of a single shock wave pressure at the front 150 kPa (1,5 bar) up to 700 kPa (7 bar) and a duration of not less than 7-10 MS.(Problems of strength in biomechanics. Iphones.com, Isaakovich, Assurer and others); graduate school, 1988. - 311 S., ill.; p.163).

Communication severity and magnitude of the pressure jump at the front is not linear. Privremeni action of the shock wave is of the order of 1 MS to obtain a 99% death it should already be at least 1.7-25 MPa, which is 1-2 orders of the above mentioned quantities. (Physics of explosion / Under. edit Lupolenko, 2 so, 1 - M.: FIZMATLIT, 2004. - 832 C., Il. str-612).

The dependence of the pressure jump at the front of the spherical shock wave in air (under normal atmospheric conditions from a distance and weight of the standard charge of explosive (TNT) is determined by the formula Sadowski:

Here: m is the mass of the charge of trinitrotoluene (kg); R is the distance (m);

Examples of calculation ΔP_F, (kPa) in the table.

It is seen that the shock wave of a single explosion of condensed EXPLOSIVES quickly loses its strength and is already at a distance of several meters certainly not able to cause a person of fatal injury. But the cost of her getting thousands of times higher than the required minimum, especially in comparison with the kinetic strike elements.

Slaughter on manpower is considered a fragment (or a bullet) with energy 78,5 j on unarmored technique with an energy of 980 j, lightly armored technique with an energy of 1960 On the. (Viadev, Reference officer ground artillery. - M.: Voenizdat, 1984. - 400 C., Il., str.257).

The vast majority of ammunition used (mines, projectiles, grenades) have a charge weight of explosives from hundreds of grams to kilograms. The radius of a solid blast from them is negligible. High-explosive effect we have to strengthen throwing splinters.

From a military point of view, there is no fundamental difference between a serious injury musculoskeletal system after the explosion, for example, landmines sealed PMN (weight 0,55 kg weight of explosive charge 0.2 kg) and shrapnel wounds after the explosion, for example, jumping mines AUR-72 (weight 5 kg weight of explosive charge 0,66 kg). In the first case, the leg is torn off by only stepping on a landmine soldier, in the second case, you may suffer a few people caught under the sheaf of fragments (within 25 meters). However, it is obvious that these and all similar products are technologically complex, expensive to produce, and most importantly, extremely wasteful spending contained in the explosive energy.

To solve the problem of reducing energy and material costs, while maintaining sufficient slaughter of the effect of engineering ammunition needed way to significantly more efficient energy conversion of explosives into a remotely valid affecting factor. Preferably, h is ordinary this method did not require design complexity the use of special materials, corrosive or poisonous substances. The result should be within waste technical solutions.

Given the specific requirements for the products of military equipment and operational conditions, this implies a drastic simplification of the structure and technology of engineering a new type of ammunition. Hopping anti-personnel mine, replacing, for example MMZ-72, must consist of only one fuse, charge and light non-metallic enclosure.

It is known that repeated through small intervals, the effect on the human body percussion and even a strong sound waves, with pressure on the front less than 20-40 kPa (0.2-0.4 bar) and a frequency of 5-7 Hz causes incompatible with life trauma, excite resonant vibrations in the respiratory organs. Their resonant frequencies are all important organs (heart, brain, eyes, eardrums). Unbearable (unconscious) pain with loss of hearing or blind, vessels rupture, hemorrhage in the brain are observed already when a singular pressure drops 4-6 kPa. (Problems of strength in biomechanics. Iphones.com, Isaakovich, Assurer and others - M.: Vysshaya SHKOLA, 1988. - 311 S., ill.; p.163).

An example implementation of the method (functional analog AUR-72)

The outer shell, forming in similar sheaf fission elements, no. Charge of trinitrotoluene total weight 0.7 kg shareinto ten equal elements. Each element is installed in a separate cell lung corps, supply expelling charge weight of 0.7-1 g and a detonator, providing his explosion after departure up to a height of 2-2,5 meters On the items remaining in the cells, this explosion, for the range is not valid.

After activation of the target sensor elements sequentially intervals of time (150-200 MS) shoot into the air and explode there. Form a series of ten air shock waves with a frequency of 5-7 Hz and pressure in the front at a distance of 25 m is not less than 1 kPa.

The affected area is solid. Shock waves do not have gaps, squish around obstacles. Severe barotrauma of the lungs get all the polls. Standing, lying and hid behind the trees. Slaughter the effect of the election. Killed a living force. Material values are stored.

2. Shockwave mine trawl continuous action.

It is known that all the currently used explosives are extremely sensitive to frequent re-action of shock waves. This equally applies to industrial formulations, including the most sensitive, as well as liquid, solid, mixed and combined martial CENTURIES.

Repeated weak shock waves are relatively easy to initiate explosion of the main charge of the special engineering of ammunition, such as PR is tutankamun min, which is quite resistant to penetration by bullets and close a single tear. They reliably ignite the low-density explosive compositions in thin-walled shells, for example, gunpowder artillery in open posted by shell sleeves.

Physical mechanisms of initiation of the process of detonation of EXPLOSIVES repetitive weak shock waves are quite diverse.

It is known that if the effects of being homogeneous charge high density (cast TNT, alloys TNT-RDX and the like), enclosed in a durable case, the detonation develops in the gap between them. The first shock wave through the hard outer shell compresses the upper layer of explosives and heats it up to 70-100°s and is contained in the pores of the material gases to about 800-900°s, which is significantly higher than the evaporation temperature of most EXPLOSIVES (usually it is 350-400°).

At the time of unloading the shell is elastically deflected and pulls away from the charge, under it occurs cavity is filled with pairs of EXPLOSIVES and residual gases. The second shock wave first compresses the cavity, which leads to thermal decomposition of vapors of explosives and further rapid rise of temperature in the gap already allocating internal energy. Usually this gain is enough to start the process of detonation. The subsequent shock wave his support is. (Physics of fast processes / edited Paslatino, vol 2, a - M., Mir, 1971, 252 S., ill., str-307).

In less dense pressed explosive charge the same mechanism of resonant samsuiluna under the influence of repeated shock waves is valid for each of the pores or other cavity containing gas. Even more intensively described the effect works in low-density bulk charges, including the powder contents of the shell liners. Thin shell does not interfere with that. Single shock wave is unable to cause decomposition of the powder grains, however, repeated cycles of adiabatic heat of compression to initiate it quite successfully.

It is known that if the bomb does not contain gas pockets, but includes solid additives, the above-described initialization process develops in two stages. For example, quite homogeneous alloy of TNT with aluminium powder (alumetal) when heated to the softening temperature of 60-80°With, in combination with the drop in external pressure spontaneously foams, not decomposing. Foaming agent is air, adsorbed on the surface of the aluminum particles. The described principle underlies the production technology of low-density explosive mixtures, in particular the widely used part of the TA-15 (85% TNT, 15% aluminum).

Thus, under the influence of a series of weak shock waves podobiecstwa first heated and acquire fluidity, then at the moment of passage of rarefaction waves lose their homogeneity (foam), and finally detonate by the usual mechanism. (Kobylkin IVAN, Selivanov V.V. and others. Shock and detonation waves. Methods of research. - M. FIZMATLIT, 2004. - 376 S., ill., SCR-271).

It is known that if the impact of a series of shock waves is exposed perfectly homogeneous explosives that do not contain gas inclusions, such as liquid, adjacent to the outer surface layer CENTURIES develops bubble cavitation. Exactly the same process occurs when ultrasonic treatment fluid. The vast majority of liquids are well able to withstand compressive forces, but have low resistance to tensile stresses. Tensile strength from them does not exceed 1.5 to 4 kg/cm²or 140-390 kPa. (Handbook of electrical and ultrasonic methods for materials processing. Popilov L.Y. - L., engineering, 1971. - 544 pages, ill., str-520).

Under the action of external pressure fluctuations with an amplitude of several atmospheres in any liquid at the moment of depression themselves there, and at the time of compression slam less extensive cavities (bubbles). Since each cavity contains only saturated steam, not providing resistance to movement of the walls, at full compression of the bubble is observed hydraulic shock, accompanied by a sharp jump press the (hundreds of atmospheres) and temperature (up to several thousand degrees). In fact, every moment in the liquid is a lot of small explosions that initiates the action which is comparable or superior in strength to regular means of initiation of detonation.

The energy released during the formation of the cavitation bubble depends on its geometric dimensions. The latter, in turn, are determined by the viscosity of the liquid medium and the repetition frequency of shock waves. The viscosity of explosives on the basis of hydrocarbons depends on their temperature. Already when heated to 80-100°With homogeneous explosive compositions or melt themselves (TNT) or go into a semi-liquid state.

Thus, under the influence of a series of weak shock waves homogeneous explosive composition is first heated and acquire fluidity, then at the moment of passage of rarefaction waves lose homogeneity due to cavitation and finally detonate by the usual mechanism.

Energy costs (power and duration of exposure) in this case are even lower than the undermining of loose and pressed mixtures. The ignition of vapors of EXPLOSIVES requires heating of the gas in the pore material up to 500-700K (differential pressure in the shock front 480-910 kPa), and cavitation bubbles appear in the liquid is at a pressure drop of 140-390 kPa, and guaranteed to provide extremely sharp release of energy and powerful initiation the respective effect.

It is known that the most resistant to strong single strikes CENTURIES (cast TNT, alloys TG, plastids and other) are extremely sensitive to repetitive shock waves. This sensitivity increases with the content of the liquid or low-melting components (including such classic phlegmatization as wax and paraffin). (Physics of explosion / Under. edit Lupolenko, 2 so, 1); FIZMATLIT, 2004. - 832 C., Il. str).

Data are combined and exotic (for example, zvukokhimicheskie) methods of initiation of detonation by a series of shock waves depicted situation do not change or confirm already been said.

It is known that for initiating detonation of a low-density, gas or bulk explosive composition enough to the surface or come and reflected a single shock wave with a pressure in the front not less than 0.8-1.5 MPa or result of the action of a series of weak shock waves, the average temperature on the surface of the structure exceeded the 500-C. (Physics of explosion / Under. edit Lupolenko, 2 so, 1. - M.: FIZMATLIT, 2004. - 832 C., Il. str-235).

It is known that remote undermining of explosive ordnance and standard engineering ammunition possible, if the pressure in front of a single shock wave exceeds, respectively:

for explosive mercury - 10 MPa;

for RDX - 180 MPa;

for tetrazene and TRS - 40 MPa;

d is I tetryl - 280 MPa;

- lead azide - 50 MPa;

for picric acid - 350 MPa;

for the Ten - 120 MPa;

for TNT - 430 MPa

(Physics of explosion / Under. edit L.P. Orlenko, 2 so, 1. - M.: FIZMATLIT, 2004. - 832 S., ill., s).

It is seen that to achieve the same result (remote detonation charge arbitrary IV) the pressure in front of a solitary wave has two to three orders of magnitude to exceed the analogous parameter for the serial shock waves. Several successive wavefronts provide it with much less energy and material resources.

From a practical point of view there is no fundamental difference between the clearance volumetric explosions detonating mixture, cutting the top layer of the ground by bulldozers or search-destroy engineer ammunition manually by engineers. The desired result goes equally difficult and expensive.

For example, when continuous clearing areas for civilian purposes, according to the UN standard must be securely neutralized 99.6% of explosive ordnance. The manual labour productivity minesweeper does not exceed 50 m²per person per day, and the mechanical trawls (cutters, hoes, rollers) fit only on level ground, but completely destroy the economic infrastructure and underground utilities.

Until recently, the task fast (impromptu) break through a mine field of transport columns more or less solved by using a hinged trawl on the head tracked vehicles. A good example of this kind of gauge is a domestic trawl KMT-7. The serial tank hang on two matkovich and two blade sections (KMT-8). They also put two consoles EMB for trawling non-contact magnetic antitank minutes Encountered landmines are removed simultaneously.

When the trawl is cleared two strips of soil (width 80 cm (after rinks) and a width of 60 cm (after stab consoles). The clearance between them is 1,62 m This is sufficient for movement of the tank, equipped with a trawl, for any trajectory followed by the tank column on the direct route, in the tracks (cleared tracks are wider caterpillars). The speed of trawling depends on the parameters of the soil. On the loose soil 6-12 km/h, in the sand in the desert to 30 km/HR Tr is l guaranteed to withstand at least six explosions in mines TM-57 and two mine explosion TM-62 (actually 10-15 explosions).

The problem is greatly exacerbated with the advent of technologies of remote mining, when it became possible one salvo or bloom aviation from a great distance, for 5-10 minutes to make deadly virtually any terrain. Without preliminary exploration with a move to overcome the modern minefield of high density may not even special armor. In addition, modern mines have a multilevel system of recognition purposes. To deceive their mere imitation of the signature of the magnetic field is not possible.

To reduce energy and material costs when clearing minefields need a way to remote, quick and indiscriminately undermine all containing CENTURIES of objects falling on the road.

An example implementation of the method (functional analogue of the KMT-7)

With the outside of the hull of the armored vehicles in front of fixed standard elements of the electric generator serial shock waves. Each of them contains armored power block (with capacitors, switches, and auxiliary electronics), generator, air shock waves (block spark gaps) and a guiding device in the form of a two-piece pipe with an internal channel (caliber) with a diameter of 150-200 mm Adjacent to the unit arresters section of the pipe has a length of 6-8 calibers and is dimensioned metal. Put on a second section with a length of 3-4 m from thin plastic or lacquered cardboard. Food trawl carry from vehicle banabhatta (power) or special generator.

The electrical part of the generator creates in face of the metal pipe air sparks adjustable power (from 20-80 j 3-5 kJ) with tunable repetition rate (10 Hz to 25-30 kHz). At each discharge inside the tube is formed by a planar shock wave front, which is almost no loss of energy (channel smooth, lateral pressure on the wall is missing) reaches the output end of the light section and escapes into the atmosphere. The exhaust is at a height of 30-40 cm above the ground (so that the pipe does not cling to the obstacles). Each element of the trawl handles front strip of ground with a width of 0.6-0.8 m

The electrical part of the trawl is far enough (4-5 m) from a possible explosion. It will not harm even anti-tank mines. Replace torn off by the explosion of the light pipe requires a few seconds and can be automated. Separate holes from bullets and shrapnel on its performance is almost not affected.

The number of simultaneously operating elements of the sweep is determined by the goal (clear track in front of caterpillars, clearing a wide band for which rachada wheeled vehicles etc). The current settings of the shock wave impact sets the program of the power block. The trawl is capable of many hours of continuous operation and provides 100% of undermining any explosive objects caught in its range.

3. Shock-wave method for decontamination of porous materials

The well-known problems associated with the organization protect people from the effects of enemy chemical or biological weapons. One of the main problems immediately after exiting the lesion is the disinfection of clothing and uniforms.

Contaminated clothing is a grave danger to its owner and others. It simply cannot be touched. At the same time quickly and efficiently to clean porous materials (for example, ordinary cotton cloth) from chemical warfare agents (hereafter OB), as a biological toxins, or insects that spread infectious diseases, it is almost impossible. For this you need special equipment, large quantities of water, fuel, detergents and decontaminating reagents, usually unavailable in the field.

It is known that the vast majority of OPTIONS are chemically unstable organic compounds. They are decomposed into simpler substances by heating up to 300-450°react with water vapor and oxygen (th is s) at temperatures above 500-600° C. for Example, the formula VX at 150°50% is converted into harmless compounds within 36 h, and when heated in the atmosphere for up to 250°From completely falling apart for 4 minutes Under intense heat in the presence of oxidants combat S lose activity instantly. In the chemical munitions during the First world war from the shock-wave effects at break (even without air) immediately decomposed to 25% of the spray S. (Aleksandrov, C. N., Emelyanov Century. And. Toxic substances. The tutorial. - M, Voenizdat, 1990. - 271 S., ill., p.36-40).

It is known that the most dangerous combat OPTIONS, quite resistant to detonation and short-term heating to 250-300°With (e.g., mustard gas), is rapidly and completely decompose at a temperature of about 500°C. (Alexandrov, V.N., Emel'yanov V.I. Toxic substances. The tutorial. - M, Voenizdat, 1990. - 271 S., ill., str-137).

It is known that organic toxins (botulinum, Staphylococcus, etc.) suitable for combat use, do not withstand heat above 150-200°C. (Alexandrov C. N., Emelyanov Century. And. Toxic substances. The tutorial. - M, Voenizdat, 1990. - 271 S., ill., str-257).

Small biological objects do not endure even a momentary (pulsed) heating above 150-200°because it is a deadly chemical reaction is the polymerization of proteins. This refers both to the fungal and bacteria (including spores), and to the larger flora and fauna (the seeds of plants, insects). At the same time, most of the fibrous organic material (polymer fibers, cellulose), widely used in the manufacture of clothing, described the impact is transferred without any damage.

Hence, instead of applying a continuous process of physico-chemical decontamination of contaminated clothing technology of its processing serial by shock waves is possible without loss of quality dramatically reduce the necessary time, energy and materials. The effect is particularly great in the case of a direct conversion in the air shock wave electrical or mechanical energy.

An example implementation of the method (decontamination and disinfection)

Cylindrical brush steel wire with a diameter of 1 m to rotate at a speed of 25 thousand revolutions per minute in the casing of smooth sheet metal, with a wide longitudinal slit. Between the housing and the brush leave a small air gap. The free end of each wire is moving with linear velocity 1300-1400 m/s (faster than sound) and over short distances (of the order of centimeters) is an effective generator of ballistic shock wave. From cracks in the surrounding atmosphere escapes continuous stream of shock wave energy.

Processed objects preblei the Ute to cracks and exposed to repetitive shock waves with pressure not less than 12-15 ATM and the temperature in the zone of reflection about K. The repetition frequency of the shock waves set the density of the brush. Thus provide immediate (within seconds) decomposition droplets of chemical substances and the complete destruction of small biological objects (bacteria, lice, bedbugs, ticks etc). The depth of effective treatment of porous materials is not less than 5-7 mm At a distance of more than 40-70 cm from the slit shock waves weaken and become safe ultrasonic frequency vibrations are not perceived.

The method allows to produce instant dry processing uniforms and other items of equipment from woven and porous materials. The only consumable resource is the energy consumed by the drive mechanism of rotation of the brush.

The analysis of open sources of information shows that the proposed solution at the moment in the world either don't know or just doesn't apply. Signs of use devices and ammunition, generating repetitive shock wave should be considered:

- fractional shells and mines from a distance perceived by witnesses as crackle or short horns (trumpet sounds);

- reports of cases of "trickle down" affect shock waves through the loopholes" in the Windows or doorways of protective structures;

- a disproportionate number of casualties with severe injuries the body is in breathing, vision, hearing and cardiovascular system;

is a disproportionately small number of victims from the debris (the sign of the use of explosive devices without the hard shell);

- an unusually large radius of manpower (relative to the total force of the explosion) when triggered landmines;

- reports of clusters of corpses without visible injury with intact PPE (helmets and body armor);

messages about inclusion in the composition of the transport head columns of armored vehicles with unusual-looking mounted fixtures;

- reports of cases of successful breakthroughs through a mine field of transport columns, without pre-clearing area EOD;

messages about continuous destruction of grass and small fauna (bands dead land) along the path of the transport columns.

In different parts of the Earth local wars, covered in detail by the media. Benefits from the military use of the described technology are obvious. Traces of application serial shock waves are impossible to hide. They are quite vivid and unusual, to attract the attention of many casual observers. However, a noticeable stream of messages about the facts, such as those listed above, in the press and news no.

Effect of posledovatel the generated shock waves on substances and objects characterized in that the impact produced by a series of shock waves in the operational management of duration, frequency and strength of each.
