SHIP DESIGN
"Rusitch" from Nizhny Novgorod
Description of general purpose river-marine cargo 5190 DWT vessel "Rusitch" developed by "Vympel".
Startsev S. B. Computer simulation of rotary vibrations of ship foil structures
The article presents the results of investigation and development of computer technologies of calculation of nonstationary loads at ship foil structures during their rotary vibrations that allow to determine instantaneous and aerohydrodynamic characteristics (AHDC) of foils of any plan size in a wide range of Stroubal numbers.
Kar A. R. Down flooding angle - a quasi-static method
Algorithm of ship's down flooding angle determination with the use of quasi-static method based on the physics of freely floating body is described.
Zhinkin V. B. Bi-rotary propulsor - a hydrodynamic component of multi-functional propulsion-steering complex
The author considers the design of bi-rotary propulsor that can serve as a hydrodynamic component of multifunctional propulsion-steering complex used for provision of amphibian apparatus movement and maneuvering in water and during its exit onto the shore.
Litavrin O. G. Utilization of gas turbine engine waste gases heat at heat-exchange apparatus surface temperature below dew-point
The author gives the results of investigation of experimental gas turbine engine's rendering tank economizer fed with cold water. Recommendations for decrease of negative influence of effects that arise during the operation of heat-exchange apparatuses in conditions of low-temperature corrosion are given.
SHIPBOARD POWER PLANTS
Petrov N. I., Perevoschikov S. G., Gavrilov E. I. Technical diagnosing of equipment - the way to increase the effectiveness of nuclear icebreakers use
The authors consider the main principles and methodology of nuclear icebreakers shipboard equipment diagnosing on the basis of long-term working experience and existing developments.
HULL GEAR AND ARRANGEMENTS
Valdayev M. M. Diagnosing of hydraulic drive technical condition
Using the example of hydraulic cargo cranes and steering engines the author shows the possibility of their technical condition diagnosing in case of availability of design, delivery or previously obtained data. For the cranes it is the time of execution of similar operations by different cranes. Pressures, number of switching-on and ship's yaw are diagnostic parameters in steering engines.
Kulikov N. V. Calculation of fender devices at towing of ships in ice conditions
A new methodology is given for calculation of dynamic and kinematical parameters of icebreaker and towed ship that permit to evaluate correctly the loads that effect upon fender devices and hull structures during piloting ships in ice.
Goltraph V. I., Kobzev V. V., Nefedovitch A. V., Goncharova T. A., Lemeschenko N. A. Ergonomic expertise of prospective shipboard means of data display and control
The authors give a description of a procedure for experimental evaluation of characteristics of operator's working with prospective means of data display and control, consider the results of measurements of these characteristics for the purpose of refining of ergonomic indexes of prospect shipboard control system boards' data-controlling panels.
MARINE ELECTRICAL AND RADIO EQUIPMENT
Skachkov Yu. V., Belousov O. A. Prospects of utilization of electro-chemical generator in the complex of shipboard electric power system
The article considers the possibility of increase in shipboard electric power systems installed power by the way of prospective energy sources - electro-chemical generators (ECG) - utilization in a power plant complex. Comparative analysis of shipboard energetics is made conformably to the tasks of underwater vessels use.
Vlasov A. V. On the problem of life cycle of cables with rubber insulation
The author considers the main stages of elaboration of procedure for calculation of life cycle of cables with rubber insulation at thermal aging. Values of life cycles of widely used KNR and NRShM cables are given.
INFORMATION TECHNOLOGIES
Bagaev G. V., Obraztsov A. S. Application of project data management system in shipbuilding
The article considers the problems of introduction of modern technologies of ship's life cycle processes information support.
Kovalyov A. Yu. Employment of "Ritm-Sudno" system for salvation of mechanical engineering tasks
The author tells about the experience of employment of computer system "Ritm-Sudno" by specialists of CRIST "Ritm-Inform" department in development of electric train operator's cabin module (OCM) and adaptation of OCM design for the possibility of its building at a shipyard.
SHIPBUILDING AND MARINE ENGINEERING TECHNOLOGIES
Gorbach V. D., Hvalynsky V. N. Residual reactive stresses of spherical shell after welding-in of branch tube
The authors propose an approximate calculation of residual welding reactive stresses in spherical shell that arose from its multiple-pass welding with cylindrical branch tube.
Agunov A. V. Energy-saving modernization of shipyards welding equipment
A simple approach to refining of welding power sources available at shipbuilding enterprises by power factor correction units is described. The proposed approach is an inexpensive salvation for the problem of supply main quality improvement and decrease of electric power consumption by welding equipment.
