Opis:
This paper presents an analysis of environmental and technical conditions necessary for working out a possibly most favourable propulsion system for a two – segment passenger ship intended for navigation between Berlin and Kaliningrad. There are presented various types of propulsion systems for small ships as well as analyzed their possible applications and consequences. In this work there were taken into account system’s reliability, efficiency, dimensions, mass and costs of manufacturing, assembling and possible replacing the system components as well as an impact on maneuverability and natural environment. With taking into account the above mentioned criteria it was finally found that the diesel-hydraulic system fitted with two azimuthal ducted solid propellers is the most favourable. There are also presented a schematic propulsion and control diagram, three-dimensional arrangement drawing of system components as well as assembly drawing of the designed azimuthal propulsion system.

Opis:
This paper presents course of research on ferro-fluidal seals used in water. The tests were carried out for a hydrophobic magnetic fluid and specially selected profiles of sealing lips at various linear velocities in sealing unit. Though the tests were preliminary their results showed that the research on application of magnetic fluids to seals working in liquid environment should be continued. From the point of view of development of ring drives the most important advantage of ferro-fluidal seals is their smallest drag as compared with seals of other types.

Opis:
This paper contains an economical analysis of three selected variants of power plant for inland waterways passenger ship intended for operating on Berlin-Kaliningrad route. Purchase cost of elements of the ship’s energy system and fuel consumption cost were assumed as the assessment criterion for the analyzed variants of the ship’s power plant. The economical indices : Average Annual Cost (AAC) and Net Present Value (NPV) were taken into consideration.

Opis:
The article discusses the issue of balancing energy processes in turbine engines in operation in aeronautic and marine propulsion systems with the aim to analyse and evaluate basic operating parameters. The first part presents the problem of enormous amounts of energy needed for driving fans and compressors of the largest contemporary turbofan engines commonly used in long-distance aviation. The amounts of the transmitted power and the effect of flow parameters and constructional properties of the engines on their performance and real efficiency are evaluated. The second part of the article, devoted to marine applications of turbine engines, presents the energy balance of the kinetic system of torque transmission from main engine turbines to screw propellers in the combined system of COGAG type. The physical model of energy conversion processes executed in this system is presented, along with the physical model of gasodynamic processes taking place in a separate driving turbine of a reversing engine. These models have made the basis for formulating balance equations, which then were used for analysing static and dynamic properties of the analysed type of propulsion, in particular in the aspect of mechanical loss evaluation in its kinematic system.

Opis:
The paper shows purposefulness and possiblity of automation of ship propulsion systems, especially those of POD type, intended to be used on four Baltic navigation ships: a containership, ro-ro ship, product tanker, as well as river-sea-going ship, designed within the frame of the Eureka "Baltecologicalship" project. Requirements of ship classification societies, and general ones for modern ship control systems were presented, as well as a review and analysis of currently applied power plant automation systems for diesel- electric ships fitted with podded propulsion drive (POD), were performed. Moreover real ways and possibilities of controlling ship s course and speed were indicated. Information contained in this paper may facilitate selecting appropriate design assumptions for a propulsion control system to be applied on the above mantioned ships.
