SHIP DESIGN
Aframeev E. A.
The outlook for ekranoplan building
The author considers the problems of the efficiency of introducing ekranoplans into the modern transportation system. It is shown that according to their aerodynamic sophistication and competitiveness the second generation ekranoplans in the weight range of 700-800 t will have technical characteristics on a par with modern heavy aeroplanes, while their dual-mode operation is their primary advantage over their analogs in aviation and shipbuilding.

Unsinkability of submarines: new design methods and technologies
The paper presents a dynamic analysis method for submarine statics and, based on this method, a unified computational model of submarine unsinkability. The damaged ship parameters are determined, using elements of static forces affecting the ship, and steady inertia characteristics without the conventional "intermediation" of waterline elements.
Zhinkin V. B.
The effect of trim on the propulsive performance of a ship
Based on full-scale and model tests, the effect of trim on the propulsive performance of a ship is shown and recommendations are given for determination of optimal still-water trim for full-shaped ships at low speeds for which a reduction of consumed power underway is of a primary importance.
Bobkov L. M., Blinov V. I.
On the design of superfast hydrofoil-sailing catamarans
The author gives an analysis of a book by J. Norwood entitled "Fast sailing ships. The basics of the design of multihull sailing ships". Recommendations are given for an analysis of aerodynamic properties to create superfast hydrofoil-sailing catamarans.
NAVAL SHIPBUILDING
Shmakov R. A.
Creation of nuclear submarines of designs 671, 671PT and 671PTM
The author narrates the story of the development of nuclear submarines of design 671 and its modifications 671PT and 671PTM in Special Marine Engineering Design Bureau "Malakhit".
SHIPBOARD POWER PLANTS
Khaliullin Yu. M., Temnov V. N., Moshkov V. N.
Marine anaerobic non-nuclear powerplants operating on gas-free fuel
The paper considers VMII-developed arrangements of anaerobic non- nuclear powerplants operating on gas-free fuel. These powerplants differ from conventional ones in that they are fitted, upstream of the turbine stage, with a scrubbing system to clean the gaseous working medium from solid products of combustion, also with slag-heat recovery and slag storage. A corresponding infrastructure is proposed for storage of such powerplants in shore-based depots, with a fire risk evaluation of such objects.
Yaroshenko A. V.
Mathematical description of technological interrelationship between ship systems and machinery and an algorithm of its practical application
A mathematical model is described which takes into account an actual technological interrelationship between all elements of ship's technical facilities having various physical operating principles and functionalities. An algorithm is given which permits to use this mathematical model for automated damage control of ship's weapons and technical facilities.
MARINE ELECTRICAL AND RADIO EQUIPMENT
Prikhodko M. M.
Energy-saving universal thyristor converter
The paper describes operating principle of an energy-saving portable thyristor converter with reconfigured structure of the power valve module designed for current drying of insulation of shipboard equipment without its dismantling in inspections during installation, use and repair.
Agunov A. V., Dmitriev B. F., Krasavchikov V. G.
Parallel connection of IGBT transistors in composite transistor switches. The authors consider features of operation of parallel connection of insulated gate bipolar transistors (IGBT) used for construction of composite transistor switches for semiconductor power devices in electric drive systems. Typical relationships between IGBT transistor parameters and various factors are presented and practical recommendations are given for realisation of composite transistor switches.
SHIPBUILDING AND MARINE ENGINEERING TECHNOLOGIES

Experience with application of laser technologies in shipbuilding
Advanced laser technologies are described which are used in cutting, welding and bending processes in world's major shipyards. Characteristics of NC laser cutting machines and laser technologies are compared with conventional shipyard equipment. Recommendations are given for implementation of advanced laser technologies in domestic shipbuilding.
