CIVIL SHIPBUILDING
Egorov G. V., Alekperov R. A., Tonyuk V. I. A family of multipurpose dry-cargo ships of «Caspian Express» type
The authors disclose the experience of designing by Marine Engineering Bureau of project 003RSD04 inland ships of «Caspian Express» type and its modifications. Examined are the particular features of these ships (total number of ships already built 12) as well as their characteristics in comparison with other project.
Chulkov A. M. Concerning the conformity of trawler-factory’s fishing and productive capacities
The article represents analytic dependences between daily catch, manufacturing equipment productivity and fish pre-storing accumulator capacity. Analyzed is possible definition of average value of fish concentration density in fishing area by statistic data showing fish catch performed by different trawlers types.
NAVAL SHIPBUILDING
«Novomoskovsk» strategic submarine missile cruiser leaves covered ship
Starshynov V. A. Chief naval architect
Nidziev I. I., Filimonenko A. A., Ivakin Ya. A. GIS for naval simulating complexes
Grounded in the article are basic systematologic requirements for the architecture of naval simulating complexes’ distributed geographic information system on the basis of analysis of interaction models of their software components and the most common solutions of GIS construction.
Fedotov P. A., Volkov A. S. A contribution to the problem of creation and perfection of modern control systems and technologies
Examined in the article is the structure of modern control systems for marine nuclear powerplants. The authors disclose the importance of control system’s bench development performed at a manufacturing plant in order to prevent software faults and give recommendations on the use of marine nuclear powerplant simulator when creating its control system.
SHIPBOARD POWER PLANTS
Statsenko V. N., Sumenkov V. M. Rate of sedimentation on the gas side of marine boilers heating surface
The article discloses the results of examination of the rate of sedimentation on gas side of heat exchanging tubes using experimental probe where several values of surface heating temperature has been preset. There were carried out two series of experiments on combustion of regular fuel M100B and water-fuel emulsion on the basis of regular fuel with moisture content of 10–15% using ÊÂÃ-34Ê boilers. The results showed that incineration of water-fuel emulsions results not only in increase in this fuel combustion efficiency but also in reduce of the rate of sedimentation on the gas side of heating surfaces.
Sudarev A. V., Konakov V. G. Improvement of and profitability and ecological compatibility of gas turbine plants on the basis of ceramic modules paralleling
Analytical comparison of metal and ceramic marine single-block gas-turbine engines having the same thermodynamic scheme shows that the effectiveness of ceramic gas-turbine engines is 6–7% higher, while mass-and-overall characteristics being significantly smaller. The authors demonstrate that application of multi-module ceramic gas-turbine engine allows not only to reduce engine’s mass and volume but also to extend sea endurance, remove repairs downtime, significantly increase mean performance factor for exploitation period.
SHIPBOARD EQUIPMENT
Fomin A. P. Concerning new shipboard sewage systems’ design rules standard
The author examines the main theses of shipbuilding standard ÎÑÒ5Ð.5414–2010 «Shipboard sewage systems. Design rules» put into action on July 1, 2011 and meeting the requirements of international standards on sewage systems and pipelines rules of designing and methods of analysis. Disclosed is the structure of a new standard and the most significant differences from a previously in-force directives on systems’ design rules – ÐÄ5Ð.5414–79 and ÐÄ5Ð.5601–94.
Vakulov P. S. Design improvement and estimated evaluation of stress of expansion bellows discharging elements
Described in the article are design philosophy and disadvantages of existing expansion bellows (EB); also represented are the scheme and principle of operation of a new EB with modernized design of discharging element. Examined is the pattern of influence of operational loads on discharging element; the author represents the developed design procedure of stress evaluation of a new design of discharging element as well as the results of this element parameters calculation using the developed methodic. Technological advantages of exploitation of a new EB with modernized discharging element are shown.
Realization of hydraulic actuators pulse control using electro-hydraulic control blocks. E. G. Berestovitsky, T. Kh. Gafurov, I. Yu. Grachyov, M. I. Kasyan, S. I. Ushakov
Analyzed in the article are the problems of development, creation and testing of electro-hydraulic transducers on the basis of fast-acting electromagnetic valves for control of hydraulic actuators, that results in significantly increase in reliability, accuracy and stability of their operation amounting to follow-up control systems.
SHIPBUILDING ORGANIZATION AND TECHNOLOGY
Svetlikov V. A., Demchenko V. G. Prevention of but welds geometry distortion when building thin-wall hulls of aluminum alloys
The article represents the description of ways to prevent residual geometry distortion of butt weld joints of aluminum alloyed thin-wall hull structures’ plating (gradation, angularity, buckling) on the basis of single-pass series welding with fixed gap and constrained reverse weld forming in case of down-hand, vertical and horizontal welding.
Logunov V. V., Rozinov A. Ya. Evaluation of applicability of assemblers’ non-welded fasteners for metal structures
The authors represent the values of electromagnetic and air-assist vacuum holding force depending on metal structures’ surface condition. Described in the article are methods of electromagnets’ holding force definition depending on air-gaps size and design features of magnetic coil. Also presented are the results of investigations on defining the permissible mass of assemblers’ non-welded fasteners, as well as the curve of holding force changes.
SHIPREPAIR AND UTILIZATION
Linnik E. V., Antonenko S. V. Structural analysis of three-sectional floating dock as a spatial platy structure
The author examines deflected mode of three-sectional floating dock of 35 600 tons load-carrying capacity loaded with uniformly distributed in diametral plane load and with «Alexey Kosygin» lighter docked in it.
Bashurov B. P., Tormashev D. S. Choosing the strategy of pumps maintenance and repair for marine diesel plant’s main engine servicing system
Analyzed in the article are various types of strategies and systems to control servicing of technical devices during exploitation. As applied to the pumps of «marine diesel plant’s main engine» complex systems, the authors examine interconnection between strategies of their technical use, maintenance and repair. From the point of view of cost minimization a system of servicing according to actual technical condition is shown to be preferable. Adduced are conditions of its practical realization and program formation mechanism.
