The invention relates to sonar technology and relates to the creation of devices for setting and sampling (OLA) flexible extended towed antennas (GPBA) on submarines and surface ships. GPBA designed to receive sonar information, pre-processing and transmission to the on-Board apparatus for forming stacks of directional characteristics and secondary processing. Known towed vessel longest hydroacoustic antenna representing connected in series in one linear system of cable-tow, GPBA containing acoustic receivers sound pressure and electronic devices pre-processing and compression of the information, placed inside a sealed hose shell filled with liquid or pseudogenes (gel) filler (patent RF №2136019 dated 27.08.1999, No. 2229734 from 27.05.2004). GPBA have a length far greater than the linear dimensions of the carrier-ship and use the cable tow removed from the vehicle by a distance sufficient to reduce the level of own ship's noise. The length of such antennas may be from several tens to several hundreds of meters. The necessary manipulations associated with the production and harvesting of GPBA are using the devices for setting and sampling (OLA) (Y.A Koryakin, S.A. Media is new, GV Yakovlev, Naval sonar equipment, St. Petersburg, Nauka, 2004, p.62]). Such devices are intended for storage, etching into the sea to work for its intended purpose, towing and winder, GPBA after work. As a rule, OLA includes a winch drum which is wound in different cases, depending on the placement of the winch on the ship and methods of setting GPBA, or the cable-tow, GPBA completely, or only the cable-tow. In the latter case, the antenna is placed in a tubular storage (hangar) for GPBA, which represents the pipe in the form of a long cylindrical shell that runs from the winch along the hull of the ship to its aft end. Through the tubular store GPBA is placed in the stream. To stabilize the motion of the antenna in the stream it is supplied at the terminal stabilizer, the body of which is made in the form of a hollow body of revolution consisting of thin-walled welded together metal parts in the form of a hemisphere, a cylinder and a cone. In both cases, the end body also performs the role of a "tube" tube store. In some constructive solutions winch and tubular storage form a single loop seal, in the other - winch and tubular storage are not sealing correctly. (Y.A. Koryakin, S.A. Smirnov, G.V. Yakovlev, Ship gedroyc the statistical technique, St. Petersburg : Nauka, 2004, p.62). For etching GPBA used hydraulic method, in which the contour of the sealing winch tube store, or only in a tubular storage, an excessive (relative to external hydrostatic) hydraulic pressure. This pressure pushes out of the hangar end of the body and then to the antenna creates a pulling force that is directed as a stream to the exit of the hangar. The device performances-sampling RF patent No. 2171197 from 24.01.2000. is the closest analogue technical solution to the proposed device. The device prototype includes: - winch for winding thereon the cable-tow, a tubular storage that hosts GPBA and end body with a nose tip in the form of a hemisphere, device for sealing the ends of the tubular storage, one of which is placed at the entrance (near the hoist side) of the tubular store and made in the form of seals, through which passes the cable-tow, the other output (opposite end) of the tubular storage, in the form of a concave hemisphere, mating with a spherical tip end of the body, device create excessive hydraulic pressure in the internal volume of the tubular storage, made in the form of a centrifugal pump, connect the tion with the one closest to the winch its end sealed pipe. When the pump and winch to the production at the tube store through the gland seal cable creates excessive pressure, which pushes the tail stabilizer from the hangar to the stream and under the action of pressure drop in the hangar and pull the drag stabilizer GPBA etched into the stream. The known device is effective only when GPBA is completely within the tubular storage, and the winch is only the cable-tow. A significant difference in the diameters of GPBA (60-80 mm) and a cable-tow (15-20 mm) and significantly higher radial stiffness of the cable allows you to create the entrance of the tubular storage effective lip seal (EN 217197 C1 24.01.2000) and to ensure that the pump needed to put the antenna traction. At large apertures GPBA, when it cannot be fully accommodated in the tubular storage, a large part of GPBA wound on the winch drum, and the smaller is the tube store. In this case, problems occur in which the known device does not provide the release of GPBA for the following reasons. For GPBA, which is filled with gel or liquid thin-walled flexible tube inside of which is placed acoustic receivers, electronic components pre-processing information and, the transit wire and power elements, it is impossible to use a lip seal, because when the feed antenna through such a seal, the shell will deform and stick relative to the power antenna elements in a direction opposite to the setting, when this occurs the flow of liquid or gel inside antenna in the same direction ("effect of tube"), which leads to disruption of attachment of acoustic and electronic units inside it and bloating shell near hard walls in the antenna at the approach to the gland seal, and ultimately to the termination of the production process and damage to the antenna. This is a significant disadvantage of the device-prototype Objective of the claimed invention aims to remedy these disadvantages of the known technical solutions, while the technical result is the implementation of stage-sampling extended GPBA, part of which is wound on the winch unit, and a part is in the extended tubular storage without damage. To achieve the technical result in the device arm and sampling (OLA) flexible extended towed antenna (GPBA)containing winch, with a wound on her cable-tow and part of GPBA, tubular storage, which is another part of HPBA and its terminal stabilization of the ATOR, the device is sealing the ends of the tubular storage, one of which is placed at the entrance of the tubular store, the other at the opposite end of the tubular storage device of the redundant hydraulic pressure in the internal volume of the tubular storage, new features, namely the sealing device in the middle to the winch end of the tubular storage is made in the form of a cylindrical module of the same internal diameter as the tubular store rigidly and hermetically United with him, inside the module is a set of diaphragms made of an elastic material, the outer diameter of each orifice is equal to the inner diameter of the cylindrical module, each of the diaphragms is made the Central hole with diameter equal to or smaller diameter casing, GPBA, each of the diaphragms is divided into segments by means of radial incisions, and the aperture through the annular gasket mounted so that the notches on the subsequent diaphragm is displaced in a circle relative to the previous one. The cylindrical fastening the module to the tubular storage can be performed with end flanges. To improve the processability OLA " o " ring seal can be made integral with the diaphragm of elastic material. The basic idea of the invention of zakluchaetsa, on the entrance of the tubular storage instead of hard seals installed device made in the form of a cylindrical module with a set of diaphragms made of an elastic material, the outer diameter of each of which is equal to the inner diameter of the cylindrical module, and an internal diameter of less than or equal to the diameter of the shell passing through it GPBA. The geometry of such diaphragms is such that under the action of excess pressure segments of each aperture are deflected from the vertical position, out of contact with the surface of the hose sheath, HPBA and form an annular gap whose length equals the length of the set of apertures, and the hydraulic resistance of the flow it enables the creation of excessive pressure in the tubular storage, sufficient for the buoyancy of the tubular storage terminal stabilizer-"the tube" and bleed GPBA in the thread. Thus, the appearance of some stretch of GPBA increase the diameter of the hose membrane due to a pressure drop occurring on the shell of the antenna at the entrance of her in a tubular storage, it does not stop GPBA or damage, because with the passage of this section of GPBA through a set of apertures thickening of GPBA at the approach to the entrance of the tubular storage causes an increase in the pressure flow from the centrifugal pump, which pushes NEGP the coefficients of the diaphragm in contact with the shell, and increases the diameter of the inner hole to a diameter greater than or equal to the diameter of the thickening of HPBA. Since the material of the elastic diaphragms, and the friction between the antenna surface and the surface of the diaphragm due to the presence of water flow is minimal, with no damage to the shell of GPBA or her stop in the tubular storage. The essence of the invention illustrated by figure 1, 2, 3, where figure 1 shows the design of the proposed OLA, figure 2 shows a cylindrical module with a set of diaphragms made of elastic material and the longitudinal and cross-section of the diaphragm of such a set in two projections, figure 3 illustrates the interaction of the membrane antenna and segments of the apertures of the cylindrical module when creating a tubular storage of excess pressure (ID) The proposed OLA (figure 1) contains the winch drum 1 with a wound on her GPBA 2, tubular storage 3 device sealing a tubular storage 4 in the far with respect to the winch end of the tubular storage, in the form of a washer with a concave surface mating with the surface of the frontal tip end of the body 5, device 6 create excessive hydraulic pressure in the internal volume of the tubular storage, made in the form of a centrifugal pump, the sealing device in the middle towards the winch 2 the end truncateonly 3 in the form of a cylindrical module 7 with a set of diaphragms 8. The cylindrical module 7 (figure 2) comprises a cylindrical housing 9, the inner diameter of which is equal to the inner diameter of the tubular body store 3 with the flange 13, thrust washers 10 and 11 are rigidly connected with the housing 9, for example a threaded connection between them has a set of apertures 8. The outer diameter of the diaphragm 8, is equal to the diameter of the cylindrical body 9 and the inner hole 12 is equal to or less than the diameter of GPBA 2, each of the diaphragms is divided into segments 13 (for example in figure 2 on four segments) with radial notches 14, the aperture through the annular gasket 15 is set so that the notches 14 on the subsequent diaphragm 8 is shifted in a circle relative to the previous one. The diaphragm 8 is made of rubber, but they can be made of other elastic material, for example polyurethane. O-rings can be made as separate parts from the material of the diaphragms The operation of the proposed device is illustrated in figure 3. and is as follows: with the proposed geometry of the diaphragms 8, under the action of excess pressure segments 13 each aperture deviate from the vertical position, out of contact with the surface of the hose sheath, GPBA 2 and form around it an annular gap whose length equals the length of the set of dia is Rahm 8, any excess pressure in the tubular storage 3 is sufficient for ejection from the tube store 3 terminal regulator-"tube" 5 and grazing of GPBA 2 in the thread. Thus, the appearance of some stretch of GPBA 2 thickening diameter hose 16 of the shell 2, for example due to a pressure drop occurring on the shell of GPBA 2 at the entrance of her in a tubular storage 3, will not stop GPBA 2 or its damage, because with the passage of this section of GPBA 2 through a set of apertures 8 thickening 16 GPBA at the approach to the entrance of the tubular storage causes an increase in the pressure flow from the centrifugal pump, which pushes the segments 13 of the diaphragm 8 in contact with the shell 2, and increases the diameter of the inner hole 12 to diameter greater than or equal to the diameter of the thickening 16 GPBA 2. Since the material of the diaphragms 8 elastic and friction between the surface of GPBA 2 and the surface of the diaphragms 8 due to the presence of water flow is minimal, with no damage to the shell of GPBA 2 or her stop in the tubular store 3 or damage it. Thus, the proposed OLA, solves the problem of securely setting and sampling GPBA, part of which is wound on the winch unit, and the part is located in a tubular storage without damage or interruption. 1. Device for setting and sampling (OLA) flexible extended bukirwa the second antenna (HPBA), contains a winch for winding thereon the cable-tow and part of GPBA, tubular storage to host another part of HPBA and its target stabilizer device sealing the ends of the tubular storage, one of which is placed in the middle to the winch end of the tubular store, the other at the opposite end of the tubular storage, in the form of a washer with a concave surface mating with the frontal surface of the terminal of the stabilizer, the device creating excessive hydraulic pressure in the internal volume of the tubular storage, coupled with the near to the winch end of the sealed tube, and the sealing device in the middle to the winch end of the tubular storage is made in the form of a cylindrical module the same internal diameter as the tubular store rigidly and hermetically United with him, inside the module is a set of diaphragms made of elastic material, each of the apertures has an outer diameter equal to the inner diameter of the cylindrical module, each of the diaphragms is made the Central hole of diameter equal to or smaller diameter casing, GPBA, each aperture is divided into segments by means of radial incisions, and the aperture through the annular gasket mounted so that the incisions are made on each subsequent aperture is displaced in a circle is otnositelno the previous one. 2.
