Device and method of placing and clearing flexible long towed antenna Invention relates to hydroacoustic, particularly, to handling long flexible towed antennas by surface sups and submarines. Propose device comprises winch to wind the tow rope and section of antenna, tubular store for another section of antenna and antenna end stabiliser, tubular store end seals, one arranged at store end nearby said winch and the other one arranged at store opposite end, composed of curved-surface washer to fit in end stabiliser front surface, device to create excess hydraulic pressure inside said tubular sore connected by sealed pipe with seal arranged nearby the winch. Seal at tubular store end nearby said winch is composed of a cylinder module with ID equal to that said store rigidly and tightly coupled therewith. Set of elastic membranes is fitted in said module, OD of each being equal to module ID. Every said membrane has central bore in diameter equal to antenna shell diameter or smaller than that. Note here that every said membrane is divided into segments by radial cuts. Note also that said membranes are fitted via circular gaskets so that cuts on every next membrane are shifted in circle relative to those of previous one. |

Device and method of placing and clearing flexible long towed antenna Invention relates to hydroacoustic hardware. Proposed device comprises winch, tubular store, run-around rollers, mechanical pull device with tensioner, antenna clamps, drum, and return pipeline of mechanical pull device. Ejection of antenna into flow is performed in tubular store by said mechanical pull device driven by winch. Tubular store is composed of a set of bundled tubes. One of the winch drum flanges is provided with additional section. Two ropes of pull device fitted through tubular store and return pipeline are brought onto additional section rim and connected by tensioner into closed loop. In winch revolution, thrust bushes of mechanical pull device engage with clamp temporary guards. Said guards are fitted on antenna to drive antenna along tubular store into flow. |

Underwater towed search system Proposed system comprises towing ship 1, towing rope 2, heavy carrier-deepening device 3 secured on tail of towing rope 3, light hardware carrier 3 connected with device 3 by rope 5 furnished with auxiliary thrust propellers 12 with control unit arranged at bow section of light carrier 4. Deepening device 3 is furnished with winch that has recess 7, open on bow side, with sizes and configuration mating outer shapes of light carrier 4. Lengthwise guide 8 is arranged above recess 7 to accommodate movable spring-loaded carried 9 with spinneret 10 where through rope 5 is passed. Inner end of rope is reeved through guide roll 11 and secured on drum of winch 6. Light carrier 4 incorporates vertical reversing auxiliary thrust propeller 12 with automatic control system. |

Proposed towed line comprises transducer units distributed along load-carrying rope passed through head holes of split blisters fitted on the said rope and deeper incorporating articulated grid of deepening wings and float section. Every split blister consists of two sections, their head and tail parts being furnished with stepwise cutouts mating each other in taking the sections together. Note that the blister tail part assembly is locked by pivot joint, while the head section assembly is locked by lug-latches. The deeper mid-section is clip-jointed to deepening wing grid. Lower part of the latter incorporates balance wing and accommodates additional weights. Note here that floatability element represents a plate that features a wing-like stream-lining cross section. |

Device of tow line fixation in towing winch spool Invention concerns shipbuilding, particularly lifting devices for tow line setting/loosening. Device for tow line fixation on towing winch spool with vertical rotation axis includes tubular strut carrying rotating spool with cable groove. Cable is connected over block system to adjustable load moving inside strut. Spool feature groove for tension band covering tow line and capable of moving in towing winch spool groove in the process of tow line coil winding/unwinding. The other end of tension band is fixated to immobile basement of rotating support distanced from the strut within 50°- 60° sector against rotation axis of towing winch spool. |

Device for tying rope to towed underwater vehicles Invention can be used in towed underwater vehicles, dropped platforms and in wells for oil and gas extraction. The device for tying rope to a towed underwater vehicle provides for electrical and mechanical contact between the towed underwater vehicle and the towing vehicle, which allows for free winding of the rope and protects the device itself from external effects. The device consists of two sealed chambers in line, made from strong protective case and inner sections, in which there is a powered built-in support of wires armouring, unit for sealing the cable inlet the section, unit for sealing the cable itself, rotating current collector and a pressure-sealed connector socket. The chambers are joined through bearing units, providing for rotation of the inner chamber with the powered built-in support of the cable and taking up tractional axial and lateral loads. The chambers are filled with an electrically insulating liquid and have compensators for varying the volume of the dielectric liquid. The device is joined in line to the body frame of the vehicle and through a pressure-sealed connector to the neck of the vehicle. |

Device for automatic separation and folding of extensible panels of moving submersible vehicle Proposed device intended for separation and folding of extensible horizontal and vertical panels of moving submersible vehicle includes power mechanism for two-sided power action on extension mechanism which sets in motion panels connected with it and secured to hull of vehicle by means of axles; vehicle is turnable around its axles. Extension and power mechanisms ensure automatic turn of folded panels when towing speed of submersible vehicle exceeds threshold magnitude and folding of separated panels when towing speed is below threshold magnitude. Power mechanism may use energy of incoming water velocity head; it may be also provided with electric drive and worm pair. |
