Opis:
In the Faculty of Ocean Engineering and Ship Technology, Gdansk University of Technology, design has recently been developed of a small inland ship with hybrid propulsion and supply system. The ship will be propelled by a specially designed so called parallel hybrid propulsion system. The work was aimed at carrying out the energy efficiency analysis of a hybrid propulsion system operating in the electric motor drive mode and at performing the noise pollution measurements. The performed investigations have shown that a significant impact on the efficiency and on the acoustic emission has the type of belt transmission applied.

Opis:
The development and growing availability of modern technologies, along with more and more severe environment protection standards which frequently take a form of legal regulations, are the reason why attempts are made to find a quiet and economical propulsion system not only for newly built watercraft units, but also for modernised ones. Correct selection of the propulsion and supply system for a given vessel affects significantly not only the energy efficiency of the propulsions system but also the environment – as this selection is crucial for the noise and exhaust emission levels. The paper presents results of experimental examination of ship power demand performed on a historic passenger ship of 25 m in length. Two variants, referred to as serial and parallel hybrid propulsion systems, were examined with respect to the maximum length of the single-day route covered by the ship. The recorded power demands and environmental impact were compared with those characteristic for the already installed conventional propulsion system. Taking into account a high safety level expected to be ensured on a passenger ship, the serial hybrid system was based on two electric motors working in parallel and supplied from two separate sets of batteries. This solution ensures higher reliability, along with relatively high energy efficiency. The results of the performed examination have revealed that the serial propulsion system is the least harmful to the environment, but its investment cost is the highest. In this context, the optimum solution for the ship owner seems to be a parallel hybrid system of diesel-electric type.

Opis:
The dynamics of the installation process of marine risers subjected to shoal/deep seawater is studied. The riser is assumed to be a cantilevered Euler‒Bernoulli beam. The upper end of the riser is clamped on the vessel or the drilling platform. The lower end of the riser is connected to the Blowout Preventer Stack (BOPs) and Lower Marine Risers Package (LMRP). The lateral fluid forces induced by the sea wave and sea current are introduced into the governing equations of motion. The lateral displacement and stress distributions of the riser are obtained by solving the governing equation of the riser via Galerkin’s discretisation scheme and a fourth-order Runge‒Kutta algorithm. The results indicate that the riser exhibits different behaviours under various depths because of the different distributions of the flow velocity ranging from the sea surface to the seabed. In the case of shoal water, the dynamics of the riser are dominated by the sea wave, while in the case of deep water it is affected mainly by the sea current velocity and sea surface wind velocity.

The development of modern lithium batteries and propulsion systems now allows the use of complex propulsion systems for vessels of various sizes. As part of the research and implementation project, a parallel hybrid drive system was designed, built and then tested in the laboratory. The experimental studies conducted allowed for the measurements of power, fuel consumption and electric power distribution in various operating modes of the propulsion system. The research proves that in the analysed case, the hybrid parallel system meets the demand for electric energy during a typical cruise scenario, and thus there is no need to install a power generator on the yacht.

Opis:
Solution of the propulsion system of the unmanned vehicle elaborated and built in the Laboratory of Internal Combustion Engines Military University of Technology is shown in the paper. Unmanned vehicles are about to play key role in modern warfare. There are many types of unmanned vehicles. Those which can operate in urban areas, especially inside buildings are considered as a most useful for modern army. Most unmanned vehicles are battery operated, causing low range or low speed of the vehicle. Internal combustion engines are not proper for operation inside buildings, due to exhaust gases produced by engine. Connecting two types of propulsion system, defect of range in battery and gases in combustion engines are eliminated, because we can program vehicle to not turning on engine inside buildings. Using a module for those types of vehicles, we can design entire gamut of unmanned and even manned vehicles, decreasing design costs and repair time due to parts repeatability. Using a prepared propulsion module, design engineer can freely determine length, width and wheel track of designed vehicle. Designed modules enable vehicle fast return to combat ability, due to parts repeatability. One module, used as a host, can reconstruct damage vehicle. There is possibility of using different engines, enlarging list of available modules. Economic factor has also big meaning, due to parts repeatability.

Opis:
In recent years, there has been a significant development in “green” and energy efficient propulsion systems, which fits into the general trend of environmentally friendly “green shipping”. The pursued goal is to construct a safe passenger ship that is low in energy demand and equipped with a highly energy efficient, emission-free propulsion system. The paper presents main problems encountered by designers of a small, hybrid-powered ferry powered lithium batteries. The conducted research allowed to create a design of an energy efficient hull shape, which decreases the demand for energy. Completed remote control model tests resulted in a proposal of an energy efficient and safe propulsion system with good manoeuvring capabilities. Measurements completed on an existing ferry permitted completing energy balance and forming an energy management policy. The paper contains the emission calculations computed for the existing ferry that are necessary for the environmental impact analysis. The soon to be constructed, newly designed vessel will provide a valuable contribution to hybrid-propulsion, energy management and unmanned technologies research.

Opis:
Dynamic development in practically all fields of science and engineering has not passed over shipbuilding . In last years, engineers got to their use computer software which makes it possible to perform strength and hydrodynamic calculations as well as to visualize design projects in 3 D space [1-4]. At their disposal they have full spectrum of modern solutions associated with the use of advanced materials and technologies [5-7]. More and more attention is also paid to impact onto the natural environment [8,9]. Every new object must influence the environment as low as possible, beginning from building phase through its service life up to final utilization – such approach is called „green-shipping”. However , not only practical reasons are important . Clients , i.e. ship owners and passengers of ships paid more and more attention to image of floating units. During decision taking on that from whom a transport service has to be ordered , the most modern ships of an attractive image matching with place and time, are often taken into consideration. Such situation has become a basis for an idea of working out a concept of a new ferryboat for National Maritime Museum. As the ferry has to navigate in „the heart of the town”, then , apart from strictly marine and engineering aspects , an important factor of its designing is its expected image - a set of significant meanings and emotions written in architecture language. The new ferryboat , like its historical predecessors , will never leave urban water routes.

Opis:
The battlefield was changed during many years and the weapon was developed also. Unmanned vehicles are one of the new kinds of weapon. They have different mass, executed tasks and the scope of autonomy. Their hybrid propulsion system increase traction proprieties of these vehicles considerably. The concept of the hybrid drive for the small unmanned vehicle was the main goal of the work. It was made assumptions, that the vehicle will have the mass approximately 1 ton, running on six wheels with the speed up to 60 km/h. The vehicle will have the combustion engine power 25 kW as the basic source of energy, Energy will be accumulated in batteries the mass 48kg and specific power 2667 W/kg. The single electric engine will propel six wheels of the vehicle. Four rare and front wheel will by steered. Units of propulsion system were selected with using the computer program ADVISER2004, and traction effort versus vehicle speed was determined on the base of the movement equations of the vehicle. The drive of the vehicle in unsteady condition was simulated using the program ADVISER2004 accord to the tests of ECE, FTP and 1015. It was affirmed that the vehicle with the chosen propulsion system could move with the speed more then 60 km/h on the asphalt roadway and below 50 km/h on the sandy road. It can to surmount the slopes 60%. Fuel consumption is circa 4 l/100 km in simulated drive test with the limitation of the maximum speed up to 60 km/h. The run range was circa 12 km as the electric vehicle.
Pole walki zmieniało się na przestrzeni wielu lat tak samo jak środki walki. Jednym z tych środków są pojazdy bezzałogowe. Różnią się one masą, wykonywanymi zadaniami oraz stopniem autonomii. Wyposażenie ich w hybrydowe układy napędowe znacznie zwiększa ich właściwości trakcyjne. Celem pracy było opracowanie koncepcji napędu hybrydowego do małego pojazdu bezzałogowego. Założono, że będzie to pojazd o masie ok. 1 tony, poruszający się na kołach z prędkością do 60km/h. Podstawowym źródłem napędu będzie silnika spalinowy o mocy 25 kW, a energia będzie gromadzona w akumulatorach o masie 48 kg i mocy właściwej 2667 kW/kg. Pojedynczy silnik elektryczny będzie napędzał sześć kół pojazdu za pomocą wałów napędowych, w tym cztery koła kierowane. Zespoły układu napędowego dobrano przy wykorzystaniu programu komputerowego ADVISER2004, a charakterystyki trakcyjne wyznaczono w oparciu o równania ruchu pojazdu. Za pomocą programu ADVISER2004 symulowano jazdę pojazdu w stanach nieustalonych zgodnie z testami ECE, FTP i 1015. Stwierdzono, że pojazd z dobranym układem może poruszać się z prędkością ponad 60 km/h pod drodze asfaltowej i poniżej 50km/h po drodze piaszczystej, pokonywać wzniesienia powyżej 60% przy zużyciu paliwa około 4 l/100 km podczas symulowanej jazdy wg uwzględnianych testów przy ograniczeniu maksymalnej prędkości do 60 km/h. Zasięg jazdy przy napędzie elektrycznym wynosił ok. 12km.

Opis:
Comparative analysis of harmful compounds emission of classical and distributed propulsions applied on the AOS motor glider, taking into account the perspective of the development of hybrid propulsions. A novel path is indicated by so-called distributed aircraft propulsion. The advantages and disadvantages of this type of solutions are presented, as well as the conceptual design of the distributed propulsion for the AOS 71 motor glider. In the paper there were compared the emissions of harmful compounds generated by a hybrid power unit developed for the airframe of AOS 71 motor glider - traditional propulsion, so-called focused (one-propeller) and dispersed propulsion (multi-propelled). Functional diagrams of both types of propulsions solutions are presented. Construction and aerodynamic constraints of both propulsions are discussed and comparative analysis is made. In the traditional version of the propulsion (so-called focused propulsion). the propeller is driven by an Emrax 228 electric engine with effective parameters: N = 55 kW, M = 120 Nm. The power source is a battery set with a capacity of 16 Ah and a range extender powered by a LCR 407ti rotating piston engine with maximum power of 28 kW. In the variant of the distributed propulsion. Ten electric engines of AXI 8120 type were used to drive small propellers arranged along the wingspan. The power source in this variant is analogous to the variant with the Emrax electric engine. For the adopted variant of the flight mission of the motor glider. a flight trajectory model was developed, which was used to determine the load of the power unit. In laboratory conditions. emission tests of both propulsions were conducted. The results are summarized in charts and discussed in the conclusions.
