Opis:: The ship propulsion solution based on unconventional thrusters driven by electric motors is most often applied for the multi-mode ships. These ships ought to have dynamic positioning system. It forces an application of a few thrusters (most often four, seldom more up to eight). Records from a number of multi-mode ships show amean load of less than 40% of maximum load on the propulsion system. In other side the demand for electric energy of ship industrial part is large, more often than for the propulsion part. In that case the diesel-electric propulsion system application may be economical, because the electric energy generation for all ship's purposes makes possible the main engines work on the optimum loads on lowest specific fuel consumption and allows them a long-term work on heavy fuels. For multi-mode ships like cable ships, suppliers, drilling vessels are convenient an application of unconventional thrusters with direct electric propulsion as well, especially for dynamic positioning systems. The efficiency of the thrusters is a predominant factor for the successful and economical operation. Forecasted development and rise of quantity of diesel-electric propulsion (it means with electrical transmission) would cause increased interest of unconventional thrusters. Ultimately they may revolutionize ship propulsion systems.

Opis:: Recently a huge progress in the field of electrical machines makes them more available for aviation. Assuming a big leap forward of electric technology in the near future, many research institutes around the World examine a revolutionary propulsion system which employs electrical machines. This idea can be a perfect response to a drastically growing air traffic and its demands about emission and fuel consumption reduction. There are already manufactured full electric, ultralight airplanes, which show that the technology is promising and future-proof. What is more it seems to be a key enabler for the development of the other technology that will influence the future of aircraft design and will allow introducing completely new airplane architectures. That is why Institute of Aviation in collaboration with The Ohio State University conducts investigation and analysis on feasibility of using such systems for aircraft propulsion. For this task a completely new tool based on Numerical Propulsion System Simulation (NPSS) environment is being developed. It will enable to analyse the electric devices conjugated with turbine engine as a whole propulsion system in the matter of its performance characteristics. The purpose of this paper is to present some of the most promising ideas and already accomplished analysis of different kinds of architectures. The analysis and optimization of the system, as well as cost effectiveness will be presented.

Opis:: Unconventional thrusters have enhanced possibilities of direction oriented thrust generating, owing to the fact they are finding application as propulsion of chosen ships. On account on demand of navigational safety assuring (tugs, double-endedferńes, special ships, chosen cruise liners) or dynamic positioning (cable ships, suppliers, drilling vessels) the ship propulsion solution based on unconventional thrusters. That part of marine propulsion market was dominated by them. Unconventional thrusters allow possibilities of other applications like auxiliary propulsion (or emergency), bow or aft thrusters, antiheeling equipment. It is quested possibilities for other applications. By the way developing with aggressive promotion of that propulsion system advantages and presentation of theirs applications on still increasing quantity of ships, it is created an atmosphere that it is necessary tofollow this way that no return to association - modern and safe ship is a ship equipped as a minimum with auxiliary unconventional propulsion system. In a practice, ships equipped with this propulsion system, give a crew a enhanced comfort of work ditring manoeuvring and even from that reason they are pleasant seen by ship crew. It must be seen these thrusters have excellent future. The efficiency drop is about 6-8% in comparison with conventional propulsion system and increasing fuel consumption, but this is the only one disadvantage. Forecasted development and rise of diesel-electric propulsion systems quantity would cause increased interest of unconventional thrusters. Ultimately they may revolutionize ship propulsion systems.
Pędniki aktywne posiadają zwiększone możliwości wytwarzania ukierunkowanej siły naporu, dzięki temu znajdują zastosowanie do napędu wybranych jednostek morskich. Ze względu na wymagania zapewnienia bezpieczeństwa żeglugi (holowniki portowo-redowe, promy pasażerskie używane do przepraw, jednostki specjalistyczne, niektóre duże statki pasażerskie tzw. cruise liners) lub pozycjonowania jednostek (kablowce, suppliery, jednostki wiertnicze) zalecane jest rozwiązanie napędu głównego statku w oparciu o pędniki aktywne. Ta część rynku została przez nie zdominowana. Dają one również możliwości innych zastosowań np. jako napęd awaryjny (pomocniczy), stery strumieniowe, urządzenia przeciwprzechyłowe. Poszukuje się ich możliwości dalszych zastosowań. Przy okazji występując z agresywną reklamą zalet tej formy napędu oraz prezentacją ich zastosowań na coraz większej liczbie statków, wytwarza się atmosferę, że należy podążać tą drogą, że nie ma odwrotu od skojarzenia: nowoczesny i bezpieczny statek to statek wyposażony chociaż w pomocniczy napęd z użyciem pędników aktywnych. W praktyce, jednostki wyposażone w tą formę napędu dają zwiększony komfort pracy podczas manewrowania i z tego chociażby powodu są mile widziane przez załogi statków. Należy zauważyć, że są to pędniki mające przyszłość. Niedostatek sprawności w porównaniu z tradycyjnym napędem jest rzędu 6-8%, co powoduje odpowiednio zwiększone zużycie paliwa, ale jest to jedyna podstawowa wada. Przewidywany rozwój i wzrost liczebności napędów diesel-elektrycznych (z tzw. przekładnią elektryczną) spowoduje zwiększone zainteresowanie pędnikami aktywnymi. Docelowo mogą one zrewolucjonizować napędy statków.

Tytuł:: Resistance of idle propellers in marine multi-propeller propulsion systems

Tematy:: transport
high speed vessels

multi-propeller propulsion systems
Opis:: The configuration of a marine propulsion system is selected with regard to the maximum power resulting from its maximum design speed and displacement. The propulsion systems of high speed vessels use three or even four propellers, and each propulsion unit may be multi-engine. High speed vessels are designedfor maximum speeds, but their factual exploitation speed parameters are usually considerably lower - partial speed. In such cases particular propulsion propellers and engines need to be shut down. The idle propellers are dragged by the hull and they work in the so-called turbine work mode; they transfer torque to the shaft and generale negative thrust, i.e. additional resistance. Additional resistance contributes to reducing estimated speed of a vessel and increasing fuel consumption. What is more, torque generated on a propeller is transferred to the shaft and when friction resistance torque in shaft stuffing-boxes and bearings, transmission and, possibly, the propulsion engine is exceeded, mobile components rotate as a result, reaching considerable rotational speed values. torque and thrust on a propeller in this work mode may be estimated on the grounds of universal hydrodynamic characteristics of propellers. Universal hydrodynamic characteristics of propellers are used as reversion characteristics in evaluating the steering properties ofa vessel, and may be useful in evaluating resistance of free wheeling and locked propellers in marine multi-shaft propulsion systems. This paper presents charts of universal hydrodynamic characteristics of propellers for the full range of their rotational speed, the methodology and an example of calculating resistance of free wheeling and locked propellers for the given marine propulsion system.

Opis:: The paper presents a method of identification parameters of shaft line alignment and its influence on operational reliability of marine propulsion system. The discussion about shaft line parameters (bearings' reactions, bending moment and shear forces acting on crankshaft or gear box, and stresses distribution in the shaft line) which has an influence on marine propulsion system reliability was presented. Proper shaft line alignment is often a problem for repair shipyards, for aged ships without sufficient documentation. Some data can be draw by measurements; e.g. shaft line dimensions or intermediate bearings' reactions. Other data (stern tube bearing load, real axis of shaft line) have to be determined on the base of calculations. Author proposed combined experimental-analytical method for identified and optimization (correction) some existing parameters and checking power transmission system’s foundation. Specialised software (based on Finite Element Method) has been developed for shaft line alignment calculations. Main novelties of the software are elastic supports (model of bearings – boundary conditions) of the shaft line, continuous support as a model of stern tube bearing and influence coefficients calculations. An example analysis with discussion has been performed for cargo ships with medium-speed main engine. Multi-variant computations supported by measurements of the ships’ shaft line have been carried out. Changes in shaft line alignment have been proposed in order to increase reliability of propulsion system.

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:: The paper presents selected issues concerning alternative power sources and propulsion systems meant for unmanned aerial vehicles (UAVs). The implementation of new propulsions in aviation is a laborious and long-term process, mostly due to safety and economical restrictions and requirements. Broadly, exploited solutions known from automotive industry may serve as a basis for development in aerospace technology, but cannot be applied without considering specific technical aspects (related to aircraft technology and flying objects physics). These aspects are mentioned in the text and some issues concerning suitability of types of aircraft are described. The paper presented contains a review of research on non-conventional propulsion systems for UAVs, conducted in Rzeszow University of Technology. Selected results of the research the fuel cell and the solar-cell UAVs and the aerial hybrid-electric drive test stand are shown in adequate pictures. The small-unmanned flying objects seem to be an accurate basis for such research. They allow reducing costs and improving safety in comparison to full-scale manned aircraft. They are also much quicker in manufacturing and easier to maintain and repair. Moreover, due to their various applications they may comprise the target market for this kind of propulsions. In particular, the issues of parallel hybrid-electric propulsions, fuel cell and solar-cell-assisted systems with appropriate examples are mentioned in the paper..

Opis:: The paper presents some problems of carrying out measurements of energetic characteristics and vessel’s performance in the conditions of sea examinations. As the object of propulsion characteristic determination was selected the ship with fixed pitch propeller. In order to formulate models of power characteristics, in first, known physical aspect were taken and subsequently statistic theory was implemented. Models of propulsion performance were built basing on two theoretical methods of determination of required shaft power and torque at a hub, as the function of propeller’s revolutionary speed and sailing condition represented by dimensionless coefficients. Model number one, based on Silukov method presents function with variable power index, of shaft power in domain of revolutionary speed. The second one presents model of torque variations, based on Silovic – Fancev method. For verification of models were taken presented in available bibliography, results of researches of ship’s propulsion systems [6]. We also discuss the manner of reducing the results of measurements to the standard conditions. We present the way of preparing propulsion characteristics and the analysis of examination uncertainty for the measurement of torque. Statistical analysis of deviation of results, using three models, proposed in the paper. As a result of analysis, one point from primary data set was rejected due to its unreliability, what was resulting with higher adequacy of characteristics.

Opis:: W referacie przedstawiono podstawowe problemy związane z zastosowaniem dział elektromagnetycznych w wozach bojowych przyszłości. Działa takie umożliwiają uzyskiwanie dużo większej prędkości wylotowej pocisków w porównaniu z klasycznymi działami prochowymi przy mniejszej ilości materiału energetycznego (paliwa, prochu). Dlatego stosowane mogą być pociski o mniejszej masie. Można załadować także większą liczbę pocisków na pokład pojazdu. Mniejszy jest także ślad cieplny pojazdu podczas strzału. Jednak zastosowanie dział magnetycznych wymaga rozwiązania jeszcze wielu problemów technologicznych związanych z wytwarzaniem impulsów energii elektrycznej o dużej mocy, trwałości, dokładności oraz niezawodności luf, przepływu energii wewnątrz pojazdu oraz oddziaływania pola magnetycznego na ludzi i sprzęt wewnątrz i na zewnątrz pojazdu. Działa elektromagnetyczne są przewidywane jako główne uzbrojenie przyszłościowe wozów bojowych. Działa elektromagnetyczne będą stanowiły bardzo ważny element przyszłego, w pełni zelektryfikowanego pojazdu bojowego, znanego jako "All Electric Combat Vehicle". Problemy do rozwiązania, to zwiększenia mocy wytwarzanej energii, przesyłania energii, trwałości i stabilności parametrów luf oraz doskonalenia konstrukcji pocisków. Należy sądzić, że istotne zalety tych dział spowodują, że będą one mogły stać się podstawowym uzbrojeniem wozów bojowych przyszłości.
Basic problems connected with using of electromagnetic cannons in the future fighting vehicles were introduced in the report. Such cannons make possible getting a lot of larger escape speed of bullets in the comparison with classic powder cannons using smaller quantity of the energetic material (fuel, powder). That is why applied can be bullets about the smaller mass. It is possible to load larger number of such bullets on the vehicle board also. The thermal signature of the vehicle is smaller during the shot also. However application electromagnetic guns requires still solution many technological problems connected with production of the impulses of electric energy about large power, achievement high level of durability, exactitude and the reliability of barrels, the flow of energy vehicle and the influence of the magnetic field on the staff and equipment inside and outside the vehicle. Electromagnetic guns are anticipated as main future armament of combatant vehicles. They will be all-important element of future, entirely electrified vehicle, known as "All Electric Combat Vehicle". Challenges soluble are enhancement of the power of produced energy, transmission of energy, durability and the stability of parameters of barrels and improvements of missile design. Essential advantages of these guns will cause that they will be able to become the basic armament of future combat vehicles.

Opis:: The dynamic positioning systems require multi-element ship propulsion application. The chosen solutions have decisive effect on propulsion system possibilities, in ship dynamic positioning accuracy also. The automation system has an essential influence on it, because it is an integral part with propulsion system mponsible for this process. The most often ship propulsion solution based on unconventional thrusters driven by electric motor s also. A few independent propulsion systems is essential but it complicates this system, it is limited the number (most often to 4, seldom more up to eight). There are no solutions with traditional rudder and steering gear. These functions take over azimuthing thrusters because they can generale directional thrust force. It must be settle the question of the number of thruster choose and the span angle of azimuthing (most often by thruster turning). In that case it gets the possibilities of ship positioning, they may display as propulsion system characteristics, giving a view on ąuality of positioning process. The last veriflcation is made in real sea conditions when it may test if chosen solution of ship propulsion system fulfils the requirements of positioning accuracy. It was presented the examples of multi-mode ship propulsions and parameters of theirs propulsion plants.

Opis:: The paper presents the consequences for DP systems during emergency or unexpected situations like failure one or more gensets, failure one of propulsion unit, overloading electric system, getting off the course, vessel abandonment of DP work, etc. The design of DP system takes into consideration required the DP system class, the requirements of adequate classification society under supervision the ship is built. It is necessary to fulfil the system redundancy in normal operation states. When failures occur in the vessel systems, it changes the possibility of DP work. There are three DP alert levels: green, yellow and red needed the proper responses. It was prepared required procedures for crew according to ISM Code, IMCA and IMO regulations. For the vessel safety, it is important the training process all crew members, especially one of the navigating officer as DP operator and one of the engineer or electrician. They ought to know their duties during alarms, exercises and real situations, especially in DP operation. The human factor ought to be taken into account as well. The DP operator may directly initiate the loss of vessel position or interact with technical failure events, which then contribute to a loss of vessel position. The important problem to solve is how to avoid emergency situations. It’s time for quick and important decisions for further vessel’s activity.
