DAK pl (Rubin, Ocean, Rubikon, Skat, Skat-BDRM, Skat-3), a number of hydroacoustic complexes and systems for surface ships ("Rubin", "Ocean", "Rubikon", "Skat" "," Polinom ", station of detection of submarine sailors" Pallada "), stationary systems" Liman "," Volkhov "," Agam "," Dnister ".
Hydroacoustic complexes for sub-water chambers, set up by the industrial enterprise - unique technical means, the root of those who find knowledge and great admiration in hydroacoustics. Yak was only one assistant, the establishment of the appearance of the underwater chapel of the sound tracker for the folding is similar to that of the establishment of the appearance of half a candle to the country in a few kilometers on a nice sleepy day, for the time of the day about navkolishnє middle ground. Osnovnі zavdannya, SSMSC virіshuyutsya gіdroakustichnim complex pіdvodnogo chovna - viyavlennya pіdvodnih chovnіv, surface korablіv, torpedoes rezhimі shumopelengovanіya, automaticity suprovіd tsіley, viznachennya їh coordinate klasifіkatsіya tsіley, viyavlennya i pelenguvannya tsіley in rezhimі gidrolokatsiі, perehoplennya gіdroakustichnih signalіv a wide dіapazonі frequencies zabezpechennya sound underwater sound at great ports, safeguarding of the nearby situation and safety of sailing, lighting of the ice situation when swimming under ice, safe of mini-torpedo ships, etc. In addition to the important buildings, the complex is guilty of the power of the automated control system, the system of guarding the power of the power, it is guilty without interruption of the work of the folding hydraulic systems for the safety of the function of all the water supply systems. At the complex є simulators of all systems of the hydroacoustic complex, which will ensure the creation and training of a special warehouse.
The basis of any hydroacoustic complex is antennas, phased discrete folding grids, which are stored from p'zokeramic conversions, as they are guilty of preventing the reception of signals from the water center to the main floor The head of the DAK - detects signals on the most powerful noises, the noise of the traffic during the Russian chapel, the sea noises, which can be used for the purpose, and even for the bagatokh officials, and that the brown signal is masked.
The current DAK is an even foldable digital complex, which processes the great information flows in the real hour mode (the skin antenna of the complex is stored in thousands, or tens of thousands of other elements, the skin of which is to blame, but the chipping is synchronized). Yogo robot can only be used for new and innovative systems that can be used for one hour, in terms of space, and of a wide range, in frequency, guarded by exuberant acoustic fields.
The most important and most relevant element of the complex - attach a visualized information. When the cycle starts, it’s not only scientific and technical problems, but rather ergonomic, psychological problems - it’s not enough to receive a signal from the call center, it’s necessary for the operator to the complex (but at the most important moment) the safety of the ship, and the relocation of powerless targets, surface, sub-water, winds, which represent a potential threat or interest for the sub-water chauffeur. І vendors constantly balance on inter-problems - from one side, to visualize the maximum amount of information, to become complex, and necessary for the operator, from the other side, not to break the "Miller's rule", but in general
The specialty of the hydroacoustic systems is important, especially the antenna - it’s pricey to the point of being good, good enough to be able to work without repair, and replace it for more than a three-hour hour - in the minds of the combat service, it’s impossible to repair a hydroacoustic antenna, as a rule.
The current DAK cannot be seen as a self-sufficient system, the system is closed, but only as an element of the integrated system and caution, which is won and victorious without interruption on the basis of information about the process of development of the system, etc. the situation in the system, for analyzing tactful situations and types of recommendations for the registration of the current regimes of the DAK in the given situation.
The development of hydroacoustic complexes for the submarine chavna - without interruption of the targeting of a potential adversary, from one side, oskilki the most important, the establishment of the DAK - no parity in any given situation (the enemy of the enemy) by means of increasing the distance of the DAK, moreover, in the main in the passive mode of the leather-finding, which allows the development of the process, but without unmasking the power of the creation, and with the shipbuilders, the designers of the generation of the new water ships, With a new project, to navigate with a new skin motivated by a ship, and it is necessary to generate a signal that is lower by orders of magnitude than the noise of the sea. Apparently, the main point of the modern hydroacoustic complex for the submarine chapters of the XXI century is the price of the development of the development of the complex and the development of the chapel;
Dosvid design DAK pl, which є in our institute, allows us to see the main problem directly, such as a significant increase in efficiency in the closest possible.
1. DAK with conformal and conformal-curved antenna
The decrease in the density of the squares, connected with the zusilli of the designers for the optimization of technical solutions for the construction of the building and the mechanisms, called for a decrease in the range of the DAK for the current square. The larger apertures of traditional antennas (spherical or cylindrical) are surrounded by a geometrical nose part of the body. Obviously, in the whole situation, the branch of the conformal (confused with the contours of the square) antenna is of a total area, and this means the energy potential which significantly overrides the analogous indicators for the tra-Dizion antennas. The first signal at the end of such antennas appeared altogether in the distance.
More promising straight ahead є the root of the conformally-curved antennas, the rostalized sides of the square. Dovzhina such antennas can become tens of meters, and the area - more than hundreds of square meters. The development of such systems is associated with the need to update a number of technical problems.
The conformally-curved antenna grows in the area of overburdened with inhomogeneous sickness, enriched with a structural gap, and also a gap in a hydrodynamic walking, including a winy for a breakdown, destroyed by a body of a stream. Acoustic screens are traditionally stagnant for lowering the flow of the switch to the antenna, which is not efficient enough in the low-frequency range of robotic on-board antennas. By means of a quick way to secure efficient robots of on-board antennas, judging from the overseas information,, in the first place, constructively differentiate the most noisy cars and mechanisms in such a rank, other pouring into the on-board systems, the algorithm of different transfer to the DAK tract (adaptive methods of compensation for structural jitter, including the pickups of the pickups that are placed in the middle of the antenna). Velma is promising to see the so-called "vector-phase" methods of information processing, so that the efficiency of the robot can be improved for the complex for the development of the spinal processing of watering in the vice and the quickness of the water. In one step, the reduction in the flow of the hydrodynamic isthmus, which flows into the efficiency of the conformally-curved antennas, ) reduce the flow of hydrodynamic transfer to the DAK tract.
2. Adaptive algorithms for processing hydroacoustic information, narrowing and widening
For "adapting" it is traditionally reasonable to build a system and change its parameters in fallowness from the development of new minds with the aim of improving its efficiency. One hundred percent of the processing algorithms for the term "adaptation" depend on the processing path (in space and hour) for the processing path with the characteristics of the signals and the conversion code. Adaptive algorithms are widely used in specific complexes, and their efficiency is in the main hardware resources of the complex. More sophisticated algorithms, which provide a wide-hour minimum to the channel by extending the signal. The stagnation of such algorithms allows one hour to receive information about the channel for the extended signal. Dzherelom such information can serve as adaptive dynamic oceanological models, which predict with sufficient reliability the temperature, gustini, salinity and some other parameters of the middle in the area. Such models run and spread widely behind the cordon. The confirmation of sufficient reliable estimates of the parameters in the channel is wider permissible, judging by the theoretical estimates, in the form of adjusting the accuracy of the values of the coordinates of the center.
3. Acoustic systems, spaced out on kerovable, non-powered, underwater devices, as a result of polystatic detection in active mode, as well as a fanciful trick on the bottom of the water
Pidvodny choven itself is a majestic sporuda, more than hundreds of meters long, and far from all the projects that are necessary for the safety of the power supply, you can be virtualized by the ship's gate for the development of the water supply systems. One of these buildings is the discovery of the bottom and the frozen facilities, which provide security for the ship. If you look at the object, it is necessary to get close to it as close as possible, without opening it at all the hazards of moisture-proof. One of the youngest gates of the last of the problem is the stem of the single-bed, independent, independent device, which is installed on the front-door, which is built on its own, or the gate of control according to the required cable connection. In fact, the plant is similar to the stems of the hydroacoustic complex itself, ale of a miniature one, which can be used as a battery, which is placed on a small self-contained annex, which is built to stand out from the water chapel in the lurid sounding backward, sticky In the United States, there are such aparaties and enter to the warehouse of the new generation of water supply units (of the "Virginia" type).
4. Development and development of new materials for hydroacoustic redesigns, which are presented in a less mode and part
Piezoceramic conversions, from which antennas for sub-water chambers can be installed - superbly folding designs, p'zokeramika by itself is even more critical material, and requires significant power to achieve the highest efficiency And for a long time, there has been a lot of jokes about the material, but by these authorities, the transformation of energy into an electric one is not a polymer, a lightweight, a technological one.
The technology behind the cordon led to the introduction of polydimensional PVDF-type floats, which are volodiut p'useffect and handles for the victorian in the designs of the curved antennas (spaced on the board of the chapel). The problem here is that it’s in the first place in the technology of the production of these products, which will ensure the sufficient efficiency of the antenna. Even more promising to build the idea of stemming material, as volodya by the authorities of the p'zokeramika, from one side, and by the authorities of the zhisnogo screen, muffling (abo rozsiyu) signals of the enemy's pilot, and lowering the power of the ship. Such material (piezoresin), applied to the hull of the underwater chapel, actually rob the entire hull of the ship with a hydroacoustic antenna, without providing a hundred percent increase in the efficiency of the hydroacoustic systems. An analysis of foreign publications showing that in the United States, such boxes have moved into the stage of pre-early education, at that hour we have progressed in the last ten years in the last ten years.
5. Classification of goals
Establishment of classification in hydroacoustics is a tricky problem, it is tied to the need for assigning a class for information, which is adjusted in the noise direction finding mode (in the small world - for the data of the active mode). At first glance, the problem is easy to see - it’s enough to save the spectrum by yelling about an object, correcting the data from the base, and rejecting the information - well, for the object, right up to the commander’s name. On the right, the spectrum should be covered in a wide range of motion, angle of view, in the area without a hydroacoustic complex, the spectrum should be hidden in one's own way, in a To tackle the task of razp_znavannya on the spectrum is practically unconnected. That is why in the vikorist classifications of vikoristoyutsya іnshі go, tied with the analysis of characteristic signs, lured to a specific class of goals. Another problem, which will require serious scientific dosages, is more and more necessary - the classification of the bottom and mumbled objects, is tied to the designations of the xv. Evidently and experimentally confirmed, how the dolphins can be finished in advance in the form of new and water-filled objects, vikonans from metal, plastic, wood. The head of presenters is the development of methods and algorithms, which implements the same order as a vison of a dolphin, a virtual analogue of preference.
6. Zavdannya self-defense
Self-defense is a complex task of securing the safety of the ship (including proto-torpedo protection), which includes detection, classification, targeting, visualization of data on the loss of protection and (or) technical problems. The peculiarity of this plant is the complex registration of data from the old DAK systems, identification of data, from the old dzherels, and the safety of information about the lost systems of the ship.
If we say more, it’s deprived of a small part of quiet promising straightforward times, which need to be taken care of, to improve the effectiveness of the folded hydroacoustic recovery. Ale vid idea to virobu is a great way, which is due to the presence of advanced technologies, the current pre-existing and experimental basis, the advanced infrastructure from the production of the necessary antennas for other equipment, etc. It means that the rest of the rock is characterized for our enterprise by the serious technical redevelopment of the federal and vocational base, so that it became possible to start financing within the framework of a whole series of federal special programs, such Zavdyaki tsіy fіnansovіy pіdtrimtsі for ostannі p'yat rokіv away povnіstyu vіdremontuvati i suttєvo modernіzuvati naybіlshy in Єvropі gіdroakustichny opitovy pool, scho znahoditsya on teritorії BAT "Concern" Okeanprіbor "radically onoviti virobnichі potuzhnostі incoming to the warehouse concern serіynih zavodіv, zavdyaki chomu Taganrozky plant" Arrived ”becoming a well-established business enterprise in Russia. We are building new virobnits - p'zomaterials, hand-made boards, in the future - new virobnic and scientific areas, stands for setting up and building possession. After 2 - 3 rockets of virobnichi and scientific efforts of the enterprise, when the "bank of danikhs" has received new ideas and retail outlets, allow to start until the end of the hydroacoustic recovery of the fifth generation, so necessary for the marine life.

The tactics of counter-fighting are often carried out to the point of making a joke and detecting enemy submarines behind the aid of acoustic sonic forces earlier, not to destroy the enemy.
At the same time, the center of the navkolishny submarine of the middle of the swell has the most important values, especially those parameters, such as the zone of acoustic safety and the position of the underwater chapel is obviously "thermoclin".
Zones of extraordinary and circular areas and near the submarine ship. The sound that goes straight downward towards the convergence point, rots out in the zone of insecurity, breaks in fallowness due to the pressure and temperature of the water, collapses uphill and downward along the road to the surface along the spiral through the middle of the standard halls, such as
The commander of the ship, if you don't mind not eating in the region, besides, de, on your mind, there is a meta, you can get out of the way. For the whole of you it is necessary to be in the boundaries of quiet districts, de the sound expands from its dzherel simply radially.
The easiest way is to take a position over the ball of a temperature striker (thermoclin), or from it, when it comes to the bottom of the water - those sounds that you see as a moving one, will be better for everything that is not in the world.
Temperature striking is a near-cordon ball under the water space, where the warm surface of the water and the larger cold areas are.
Diesel engines under the order of atomic power take the most important place in the aggressive plans of the National Navy's capital to the NATO bloc. By the tribute of the associate "Jane", in the mid-1980s the fleets of the provinces of the Indian Atlantic Union had 186 diesel engines.
Diesel podvodnі chavnyy perevagi before the atomic ones, Before them I see, sprout, less drunkenness, I’ll paint the robots of hydroacoustic stations (GAS) when we see the establishment of a counter-struggle.
In this hour, as soon as the Earth press has become available, the integration of hydroacoustic technology with BIUS and control systems has been developed, as it will be based on the wide competition of the EOM. As a result, the tactical capabilities of the hydroacoustic equipment have clearly changed. The dependence of the target and classification of the denied contact has been increased. In addition, it became real at once to quest for a decilkom (up to six) goals and clearly see the changes in its maneuvers, automatically remove information and continuously see it in an effortless way to visualize the system in an unimaginable way. , and if necessary, restruct.
The digital processing of signals allowed the systems of the passive location of the underwater chauffeur to reach precisely the beginning of only the noise of the bearing and the distance to it.
Nareshty, the integration of industrial systems on the basis of the EOM has simplified the control over the work and the maintenance of the GAS and allowed the speed of the service personnel, which is less important for the somewhat small ones for the water-tonnage of the diesel engines.
The main path of the acoustic station is a sound direction finding station from a distance of dozens of kilometers. In the low-frequency (220 Hz - 7 kHz) range, the reception of signals is sent to the conformal (along the contours of the nose part of the body) acoustic antenna is stored from piezoceramic hydrophones, and in the high-frequency (8 kHz) range, to the circular lead ... The cylindrical antenna also serve as a steeple for decalcom (up to chotiroh) purposes. Offense of the noise direction finding channel to add one to one. The navkolishn_y space look around the path of a swift lasting experience of the great number of transmitted 360 ° statically formed peels of the characteristic of straightness. Viyavlenі noisy meti bearings with high accuracy of the signal method.
The active tract gave the opportunity to conduct a circular look at all-direct viprominuvanny of one streak, or in case of viprominuvanny of a series of streams in the last day to change directly, as well as viprominuvate one-stitches in a singing direction. Received moon signals are displayed on the indicator screen and can be recorded for the Doppler frequency response.
The path of the passive location is on the skin board of the underwater chandelier, there are three receivers installed on the hull in the bow, middle and stern parts. The stench will take in the noise of meth, as it is a corelative image, which allows for a sufficient accuracy in value to the point behind three lines of position. Anteni to the tract can be vikoristovuvatisya yak additional for the tract of noise direction finding.
The station will secure the direct and non-directional sound underwater sound.
The path of detecting signals by the laser detector allows the emergence of impulse signals of a dynamic approach to a number of deciles of dozens of kilometers, by starting the frequency, triviality and directly to the signal.
The design of the station has a wide range of integrated circuits, the establishment of a whole change in size and weight, and the need has been increased. The data about the targets are displayed on two screens, automatically fit on the EOM auto-gasket system and control the torpedo gunner, and the commands for the gunner are sent.
Broken and simple hydroacoustic station. Vona includes noise-direction-finding taverns, moon direction-finding and passive locations. Shock and detection of targets is carried out in the mode of noise-direction-finding and detection of the signal according to the signal processing method. To see the whole distance to her, be aware of the path of vyprominuvannya straightened single severity, or by the method of passive location.
To increase the efficiency of the acoustic warning on the bottom of the water, you can also use it to increase the sound in the water and to signal the sound of the ear of wine to control the cavities.
To improve the efficiency of the GAS victorian, the device encourages the exchange of pictures to be introduced with data about the actual increase in the sound of the glibinia. The system is designed to function in the simulator mode with the simulated signals, so that it can be used for input from different purposes. All streaming information, which is entered into the system in the process of fighting robots and is played by it, can be recorded for a later revision and analysis. The system will be serviced by one or two operators.
GAS are the largest types of cylindrical section antennas. For a circular look around the space, 96 pelusts are statically molded with straight diagrams.
The value of the coordinates of the emerging goals and the step is one hour for a few hours to come in all modes for the additional EOM. In the active mode, in order to reduce the maximum range, the narrowing parameters are transferred to the vypromynuvannya (vyprominuvannoy tautness, frequency, type of modulation) with the actual hydroelectric minds in the area of caution.
In the mode of detecting signals from the guides, there is a bearing on the signal, the frequency and amplitude, the frequency of the pulses, the frequency of the passage and the classification of the signal for all signals.
The station can also be used in additional modes: a simulator, a beam graph and automatic control of a technical mill, which will prevent the detection of faulty modules.
On the remote control of the GAS there are all control organizations and two screens. On one of them there is a tricolor indication, which is a circular look indicator, instantly visualizes in the central part of the situation with its ship in the center and a circular bearing scale, and along the edges - on the frequency, course, speed), data about the course and speed of your ship, about the mode and parameters of the robot GAS. On the other screen, there are texts of "hierarchical matrices", the processing of which allows to optimize the process of controlling the apparatus. Also, the information provided, meaningfully forgives the maintenance and operation of the station and allows one operator to visit.
At the fall of 1983, the nuclear submarine class VICTOR-III was rejected by the noise and characteristics of the fourth American missile carrier of the Ohio class.
On the idea of a trip, the young ambitious captain of our submarine, nathnenny with the butts of the heroes of the Victory Day, it is not enough not to go into the bay of the enemy's base.
For acoustic masking K-324 in the Sargasso Sea, she took a small boat, as it was heading straight. Everything went well, as the speed of our submarine began to fall quickly, unimpressed on the speed of the turbine to the maximum.
Niyakі cunning and advice didn’t lead to positive results - the speed dropped to three universities.
Nichogo not porobish - brought splivati. There are few splivats not on the American coast, in the very "lіgvі", so bi moviti.
For a look at the main gwent, the noses of the cisterns were kept, the choven made a decent trim on the nis and the emergency team, the two "Kalashnikovs" and the two PMs (all appearing on the radianskiy nuclear submarine arsenal) looked at the stern part. So і, on the shaft we will wind up a yaky cable, even more mint, do not give in to a break, nor to an automaton: all the zusillas appeared as marnimis.
The commander took the decision to go to Cuba on the surface. It was then that the American people, sailors and tourists on sailing yachts were imagined.
With grief, they drove to Kubi. The commander was immediately clicked on "kilim". Ale, let us summarize about this share, turning the captain "on horseback" - an unhappy cable, winding around the gwent as an all-spirited driver, who appeared as a new American hygroacoustic antenna

In the accessible for inspecting the Maybut underwater chapel and the prototypes of the Russian Navy-Sea Fleet, there will be a new type of hydroacoustic system. Nowadays, by the end of ten years, there is a great number of people in the household who have been involved in the situation. Some purchases allow to equip with some special tools for the creation of deviceless or modernized sub-water chambers, litas, etc.
In the end of birch on the official site of the state procurement by the Ministry of Defense of the BOUs of the new replacement, there is a need for the development of the material part of the Navy. From the published information about the tender, the ministry plans to purchase 55 hydroacoustic complexes (DAK) of the MGK-335EM-03 "Krizhen" family in new modifications. For the purchase of all the necessary virobes in the vіyskove vіsskomstvo get vitratity not more than 194.6 million rubles - in the middle of Monday, 5.3 million for the complex.

For obvious tributes, the hydroacoustic complex MGK-335EM-03 "Krizhen" is built by the concern "Okeanpribor" (metro St. Petersburg). Tsey complex of features for installation on ships of small and medium water tonnage. Є Possibility of installation of all the necessary equipment both during the operation of ships, and before the hour for repair and modernization. In the last resort, the "Krizhen" system is replaced by the old MGK-355MS complex. For obvious data, at the base of the ship complex, there were new modifications, designations for operation on the new bows. Yak nasledok, DAK of the "Krizhen" family can also be victorious with individual chambers, lithuanians and stationary systems of distribution.
Regardlessly from the nose of the complex, there are similar projects and maximum unification. To the chief executives є shudder from the water chambers. The purpose is carried out in an active mode for an additional ecolocation or in a passive mode - in such a way, there will be noises of the purpose. In addition, the ability to detect signals in other complexes, which operate in active mode, has been transferred. Similarly, the automation "Krizhen" is designed for independent supravodzhuvati know the meta and type of data on the target for the control of the fireball against the defenses of the nose. Є Possibility of automated classification of the revealed object. Complexes MGK-335EM-03 "Krizhen" can function with hydroacoustic sound at low and high frequencies. Also, the transmission of a code call and a report is transmitted.
Architecture DAK MGK-335EM-03
By adjusting the operational characteristics of the complex, there are a number of important features and functions. When the hydroacoustic complex is robotic, automatic control of the level of acoustic transitions is enabled. Automation is also designed to predict the distance of the system in the presence of current minds. Є Automated control over the robotics of all components in the complex and its development. Automation is self-supporting to the robot of the units and to carry out diagnostics. If there is a malfunction in the automatic mode, the localization will appear. Є The function of navchannya operators, in the course of which vicarists are imitated.
At the basic configuration, designated for installation on surface ships, DAK MGK-335EM-03 "Krizhen" has a number of basic attachments in its warehouse, which will be able to update the factory. By the head and by the same method of caution and detection of targets in the whole range є a sub-active-passive antenna. There is a viconan at the viglyadі cylindrical building, equipped with a great number of sensitive elements. To save the necessary positioning of the antenna for an hour, the robot will use a special adjustment system with stabilization devices. Antenna height 1 m and diameter 1 m
Also on board the carrying ship is guilty of mounting a generator set, an undersilience and control, wait a minute, and also attach a digital signal processing and control and control of stabilization. All the elements of the complex are made up of themselves. The supply of electrical energy to all components in the complex is provided for an additional supply of energy supplied from general ship electrical systems.
At the operator's workstation, a remote control is installed with the necessary control bodies. Data about the underwater situation, the evolving goals and robots of the hydroacoustic devices are sent to two color monitors. The main governing bodies are keyboard and trackball, spaced on the front console. Some of the buttons and shifters are placed by hand with monitors. The distributor of the "Krizhen" system also proposes a victorian wine indicator. On the one-sided view of the main console, you can set up an additional monitor to provide information about the current situation.
Subkilnaya antenna "Krizhen"
For obvious data, the "Krizhen" family includes hydroacoustic complexes of decilkoh models, which are displayed one from one warehouse of special possession, in the middle of the antenna and the first ones. So, in the MGK-335EM-01 project, the sub-antenna will be supplemented with a towed, flexible, extended antenna. Complex MGK-335EM-02 can be towed in its warehouse and will extend the antenna. Virib MGK-335EM-04 adapts to an expanded frequency range when robots are in active mode, allowing the viral movement of torpedoes, and the Krizhen version of MGK-335EM-05 can lower the acceptable and anti-viper.
According to the official data of the concern "Oceanpribor", DAK MGK-335EM-03 "Krizhen" is capable of vibrating underwater chambers with an equivalent radius of Re = 10 m at distances of up to 10-12 km. The coordinates of the target range start at an accuracy of up to 30 'in bearing. Accuracy in terms of range of reachє 1% of the scale of distance. In the mode of direction finding noise in the complex, the building captures sounds with a frequency of 1.5 to 7 kHz. For the purpose of detecting and taking on the suprovod, the accuracy of the bearing value is set to 30 '. The mode of detecting hydroacoustic signals, which is able to respect the detecting of other people's DAKs in the active mode, allowing control over the frequency range of 1.5-7 kHz. The bearing to the dzherelo of the signal will start at an accuracy of up to 10 °.
Analyzing the nature of the received or overcrowded signals, the MGK-335EM-03 complex was originally designed to be part of the object before it was in the class of technology. With the action of the operator's help, the hydroacoustic complex of the building's response to the underwater torpedo. At the same time, there is the possibility of one-hour visualization of the systems of counter-new protection.
The complex "Krizhen" is designed to achieve high characteristics of hydroacoustic sound, as well as a great deal of special mobility. Low-frequency or high-frequency ringing will work at ranges of up to 20 km. The code call, the registration of the detected object, or the change in the distance to the new one, can be seen at the stations up to 30 km. Behind the help of DAK MGK-335EM-03, the ship's flight can be used for telephone calls from Russian submarine chambers, as well as from ships that have a strong NATO frequency range.
Complex control panel
Surely from the last, in 2017-19 rocky, the Vyskovo-sea fleet will be guilty of rectifying 55 sets of DAKs of the MGK-335EM-03 "Krizhen" family in new configurations, intended for installation on the nose of new classes. It is planned to set up a large part of the whole equipment at the hydroacoustic development stations, so that these complexes will be victorious under the water chambers and litas. Accurate views about potential problems are being replaced by complexes, due to sound reasons, at the moment of the day. Until you start getting ready, you will be able to predict and get ready for it, as the technology itself will be equipped with such equipment.
In the range of versatile new types of airborne complexes of a new type, there can be used the IL-38 and Tu-142 remaining modifications. Infected technology to undergo repairs and modernization, in the course of which we will get new possession. The project's technical update can have a selection of new hydroacoustic systems.
16 complexes will be purchased in the configuration for sub-water chambers. Ymovіrno, the whole equipment will be stashed during the future repairs of the existing ships, according to the old projects. With a glance at the wick and the equipment is being used on the armored submarines, it is possible to allow allowances, with the potential noses of the "Kryzhen" systems. Far from all the ships of the Russian submarine forces are equipped with daily means of keeping an eye on the submarine situation, through which they will require new, submarine viruses. In the world of repairing stinks, you can remove new ones with advanced characteristics.
Tsikavo, in the minds of the in-line tender there is a point about the purchase of hydroacoustic complexes, which are intended for installation on surface ships. Virib MGK-335EM-03 spun off in the same ship as a ship, and only got less development, as a result of which it could get up on the nose. There are no sound reasons for the actions in the nearest plans of the Vyskiy administration for the purchase of shipboard DAK "Krizhen" on the day.
Scheme of the shipborne complex MGK-335EM-05 with a dodatkovy lowering antenna
How to see the latest information on the basis of mass information, also seemingly, where to go to bathe hydroacoustic complexes. With the help of the products of the Ministry of Defense, the Ministry of Defense will be able to subordinate the decision to the military-sea fleet and marine aviation, promising for the success of the anti-military defense. The equipment will go to Kronstadt, Svєromorsk and Novorossiysk, as well as to the base of the Primorsky Territory. The details of the future operation of the promising systems will not be seen yet.
From the obvious tribute to the vipliv, the equipment of the sub-water chambers, lithuanians and stationary hydroacoustic systems with new complexes of the MGK-335EM-03 "Krizhen" family means positive legacies for all the prototypical defenses. In the course of business, as well as modernization of the underwater chapel, litaki, etc. otrimayut modern equipment for training for additional operations, which is a common rank to be recognized on the efficiency of their robots. As a heritage, it is worthwhile to increase the range and quality of the appearance of potentially insecure objects.
In addition to the main enterprises, connected to the development and superconducting of small enterprises, the new DAK can be used to determine the known goals, to indicate the goals of the control systems, etc. Also, the initial mode is transferred, which will take over the training of acoustic operators.
For the official data, in the middle of the week the office will complete the acceptance of applications for the recently opened tender and proceed to the selection of the owner of the required equipment. It’s not hard to get a supply contract, for which there’s a serial release of the DAK of the necessary modifications. The first idea of such a possession is planned to be done in the same flow line, but the rest is not the end of 2019. Obviously, the delivery of such viruses will be carried out one hour at a time. This means that not less than the ear of the offensive ten years of vichiznyan's defense against new possession, and at the same time with new opportunities. All the same positively signify on the potential of the Russian-sea fleet as a whole.

hydroacoustics (View of Greek. hydor- water, akusticoc- rumors) - the science of appearances, which is found in the aquatic middle and wives with rosters, vip promises and acoustic diseases. It includes the power supply of the rosette and the stem of the hydroacoustic devices, which are used for the vikorystannya at the water center.
History of development
basics of hydroacoustics
Features extended acoustic hvils near the water
The component of the event appears.
An ear of universal and fundamental ideas from the development of acoustic chills near the water was laid in the rock of Another holy life, which dictated the need for practical establishments of the Ukrainian-Black Sea fleet Experimental and theoretical robots have been promoted and promoted in popular rock and advertising in a number of monographs. As a result, many robots have emerged and clarified the features of the broader acoustic conditions in the water: chasing, extinguishing, visualizing and breaking.
The chasing of the acoustic energy in the sea water is summed up in two processes: the internal graters of the middle and the dissociation of the solutions in the salts. The first process of transforming the energy of acoustic energy into heat, and the other one transforming into chemical energy, is to bring molecules from an equally important stage, and the stench falls on them. The whole view of the chase is very growing due to the increase in frequency of the acoustic collation. The presence of important areas near the water, microorganisms and temperature anomalies can also lead to the extinguishing of acoustic damage in the water. As a rule, the losses are not large, and they include in the hallway the bowling, protein, which, for example, in the case of a breakdown at the side of the ship, it can be lost up to 90%. The detection of temperature anomalies must be produced before the acoustic experience is consumed in the acoustic zone, you can deceive yourself in the visualization.
Recognition of the cordon in the water - in the morning and water - in the bottom to make it sound like it doesn't sound like a sound 'yaniste. On small slopes, through the bagatoraz visibility of the acoustic sound between the bottom and on the surface of the vine, there is a sub-water sound channel, in which the acoustic sound can be widened over great places. The change in the magnitude of the soundness to the sound on the small slopes is to be produced to the extent of sound "changes" - refraction.
Refraction to sound
|
Refraction to sound in water: a - vlitka; b - levy; zlyva is the serpent of quickness with glybin. The broadened sound of the sound ripples through the sea, moreover, the snakes lie down in the rock and in the day, the sea in water, and for a number of other reasons. Sound interchanges, how to go from the dzherela down to the horizon with a deyakim kut, to bend, and why the vigin is to lie down in the middle of the sound in the middle: so much, if the upper ball is warmer than the lower ones, the promenade to go down to the bottom energy; When the lower balls keep their temperature, at the same time the upper balls cool down, change to burns and go back to the surface of the water, at which much less energy is consumed. To that, the distance to the wider sound is greater, less so. Vertical distribution of soundness (VRSZ) and gradation of soundness Razpodil shvidkostі sound in the rural areas of the Svitovoy ocean in a smart way and change in hours. Razrіznyayut decіlka of typical vypadkіv VRSZ: |
Razsiyuvannya and chasing the sound by the inhomogeneities of the middle.
Expansion of the sound in the pivodny sound. channels: a - a change to the sound of the sound; b - go changes in the audio channel. For the broadening of sounds at high frequencies, if the sound is even smaller, they infuse other sounds, they appear in natural waters: gas bulbs, microorganisms, etc. As a result, due to the frequency adjustments and sound signals, the range of the widening will speed up. The effect is especially strong in the surface sphere of water, which is less irregular. Rise of the sound by inhomogeneities, as well as by the irregularities of the surface of the water and the bottom of the sound, is the cause of the water reverberation, which is the strength of the sound impulse: Between the range of widening of sub-water sounds, it is itself surrounded by the powerful noise of the sea, it can be in two ways: a part of the noise of the winery is from the blows of water on the surface of the water, from the sea surf, from the noise of moving pebbles, etc.; іnsha part is tied with sea fauna (sounds, vyroblіvanі gіdrobіontami: ribs and ін. sea creatures). Tsim even more serious aspect to deal with biogidroacoustics. |
Expansion range of sound levels
The range of widening of sound signals is a folding function of the frequency of the sound signal, which is unambiguously linked to the need for an acoustic signal. Yak vіdomo, high-frequency acoustic signals quickly extinguish zvdyaki strong watery midst. Low-frequency signals against the building widen in the water environment on a large country. Thus, the acoustic signal with a frequency of 50 Hz is widespread in the ocean for thousands of kilometers, at that hour, as a signal with a frequency of 100 kHz, it is very important for a bit of a glance, but the range is only 1-2 km wide. The approximate range of the day with the help of the guided radar with the lower frequency of the acoustic signal (even more) is pointing in the tables:
Zasosuvannya area.
Gidroacoustics rejected a wider practicality, some still have not yet established an effective system for the transmission of electromagnetics from water to a small amount of meaningful things, and the sound of that, we can use the sound of water. For ciches, use sound frequencies from 300 to 10,000 Hz and ultrasounds from 10,000 Hz and more. Yak vipromynuvachіv and pickup in the sound area vikoristovuyu electrodynamic and n'zoelectric vipromіnuvachі and hydrophone, and in ultrasonic - p'zoelectricity and magnetostriction.
