    Article presents comparison of the energetic balance of vehicle powertrain - pure electric vehicle and vehicle equipped with electric hybrid power transmission. Society is more and more often persuaded to buy electric cars as an environmentally friendly solution because they have opinion of ecological vehicles. Electrification in military applications is also widely considered, especially in case of small to medium UGV’s such as wide range of robotic systems introduced to the milatary operations. The article presents the problems of comparing the efficiency and others parameters such as the range of a two presented powertrains. The research was carried out on an small unmanned land platform equipped with a hybrid propulsion system supplied as standard with Diesel power generator and electrically only powered. Energy used for charging of the battery, from tank-to-wheel, was calculated. This also enables to calculate total efficiency of electric and hybrid power transmission. By calculating different capacity of battery and power of generator, it is possible to determine the vehicle range.

    Opis:
    Article presents the energetic balance of small-unmanned vehicle hybrid power transmission. The vehicle equipped with serial hybrid transmission consisted of electric engines connected to the battery pack and small Diesel power generator. In mentioned construction, battery is used as energy buffer and combustion engine is used more as emergency power supply, and is turned on when battery is depleted. In other condition, power generator can be turned off, without reducing power of transmission parameters, except its range. Vehicles with hybrid drive are very common chosen vehicles by users. More and more often, we also talk about searching for replacement fuels for internal combustion engines, so also for those with hybrid drive. The research was carried out on an unmanned land platform equipped with a hybrid propulsion system supplied as standard with Diesel oil. The article presents the problems of comparing the efficiency of a hybrid vehicle fuelled with Diesel oil, but also with alternative fuels based on kerosene and other components. For test, three types of fuels were used, standard Diesel oil, F-34 and with experimental mixture of Jet A-1 fuel with 10% of 2-ethylhexanol. Energy used for charging of the battery, from tank-to-wheel, was calculated. This also enables to calculate total efficiency of such hybrid power transmission, powered with different fuels.

    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:
    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:
    Hybrid propulsion in underwater vehicles is the new idea of combining conventional propulsion systems such as screw propellers with other kinds of propulsion like oscillating biomimetic fins, glider wings or jet thrusters. Each of these propulsion systems has its own benefits and drawbacks, and the goal is to have them complement each other in certain conditions. This paper covers the topic of a dynamic model of the pitch and heave motion of the HUUV (hybrid unmanned underwater vehicle) using screw propellers and biomimetic lateral fins. Firstly, the simulation model of the vehicle performing depth and pitch change is presented. Secondly, the vehicle’s hydrodynamic coefficients obtained from CFD simulations are discussed. Thirdly, the results of the HUUV experimental studies in a swimming pool are presented. Lastly, simulation results are compared with those of the experiment to verify the correctness of the model. The vehicle’s motion in the swimming pool during the experiments was recorded using a submerged camcorder and then analysed using the Tracker software.

    W artykule podjęto tematykę związaną z określeniem warunków implementacji hybrydowego zespołu napędowego w bezzałogowym statku latającym. Stanowi to próbę wypełnienia niszy, jaka widoczna jest w obszarze aplikacji napędów alternatywnych w lotnictwie. W tym celu przeanalizowane zostały zarówno aspekty działania napędów hybrydowych (zwłaszcza w ujęciu gospodarki energią) jak i kryteria doboru zespołu napędowego do obiektów latających. Punktem wyjściowym dla prowadzonych rozważań jest przyjęta misja lotnicza, na którą składa się określony profil ruchu obiektu latającego oraz zadania jakie ma on wykonać (wynikające z założonych warunków taktyczno-technicznych i przeznaczenia statku powietrznego). Przebieg misji lotniczej oraz charakterystyki obiektu latającego pozwalają na określenie zapotrzebowania na energię, niezbędną do wykonania przyjętego zadania, co jest podstawą do wyboru konfiguracji hybrydowego zespołu napędowego i zdefiniowania trybów jego pracy. Przedstawione w pracy rozważania stanowią bazę dla sformułowania wniosków, dotyczących sposobu dopasowania hybrydowego zespołu napędowego do zadania lotniczego realizowanego przez bezzałogowy statek powietrzny.
    The paper presents issues concerning an utilisation of a hybrid-electric propulsion system (HEPS) in an unmanned aerial vehicle (UAV). It is an attempt of fulfilling a gap of alternative propulsions within aerial applications. The elaboration contains both analysis of HEPS energetic aspects and aerial propulsion systems selection criterions. Presented considerations base on the assumed mission, which includes motion profile and given tasks (derived from tactical and technical conditions and aircraft purpose). The characteristics of mission and aircraft allow to determine power requirements which enable to select proper configuration of the HEPS and to define its states of work. Presented deliberations may help to formulate conclusions on matching the HEPS to the mission of the UAV.

    Opis:
    Self-propelled wheelchairs favour the rehabilitation process, forcing the user to be physically active. Unfortunately, in most cases, the manual propulsion is not adapted to the individual needs and physical capabilities of the user. This paper presents the results of operational tests of a wheelchair equipped with a hybrid propulsion system in which the muscle strength generated by the user is assisted by two independent electric motors. The research aimed to investigate the influence of the applied control algorithm and the assistance factor (W) on the value of the muscular effort (MA) while propelling the wheelchair with the use of push rims. A modified ARmedical AR-405 wheelchair equipped with two MagicPie 5 electric motors built into the wheelchair’s hubs with a power of 500 W was used in this research. The tests were carried out on a wheelchair test bench simulating the moment of resistance within the range of 8–11 Nm. Surface electromyography was employed for the measurement of MA, specifically, a four-channel Noraxon Mini DTS apparatus. The research was carried out on five patients from the group of C50 anthropometric dimensions. The effort was measured for four muscles: deltoid–anterior part, deltoid–posteriori part, and triceps brachii and extensor carpi radialis longus. The effectiveness of the hybrid propulsion system was observed based on the extensor carpi radialis longus muscle. In this case, for the standard wheelchair, the MA ranged from 93% to 123%. In contrast, for a wheelchair equipped with the hybrid propulsion system, at W = 70%, the MA was within the range of 43%–75%.

    Opis:
    In this article, both problems of the internal combustion-engine’s thermal equilibrium as well as improving the DC-DC converter’s operation in the hybrid-electric vehicle’s propulsion system. The purpose of the proposed amendments is to increase the energy efficiency of the hybrid-electric vehicle’s propulsion system. Such a hybridelectric vehicle in city traffic is characterized by intermittent operation of the internal combustion engine with long pauses, which causes difficulty in obtaining and maintaining the desired operating temperature of the internal combustion engine, especially at low outdoor temperatures and intensive use of the heating system inside the hybridelectric vehicle. The result is the increased emission of noxious exhaust gas components and increased fuel consumption. The proposed solution to this problem is to apply heat accumulator in the cooling system. It is stored in the waste heat from the cooling system used to obtain and maintain the internal combustion engine’s nominal operating temperature. The paper presents the results of simulation analyses the impact of applying heat accumulator in the hybrid-electric vehicle driving in city traffic, at different ambient conditions, such as: air temperature, internal combustion engine’s load and the frequency and length of stops. The proposed algorithm for controlling the circulation of the cooling liquid ensures as soon as possible to achieve and maintain the internal combustion engine’s temperature. Furthermore, the temperature of the operating medium can be adjusted depending on the operating conditions of the internal combustion engine. Experimental studies, on the example of the Toyota Prius and Yaris, confirmed the desirability of the use of the proposed solution. Improving the DC-DC converter’s current is to change the configuration by the use of a two-phase DC-DC converter – instead of a single-phase DC-DC converter, supplying a DC-AC inverter of the DC motoring the hybrid-electric vehicle’s propulsion system. This article also includes waveforms for comparison of the properties of both DC-DC converters.

    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:
    Engines powered by compressed air as a source of propulsion are known for many years. Nevertheless, this type of drive is not commonly used. The main reason for not using commonly is the problem with the low energy density of the compressed air. They offer a number of advantages, primarily focusing on the possibility of significantly lowering the emissions of the engine. Their emissivity mainly depends on the method of obtaining compressed air. This also has an impact on the economic aspects of the drive. Currently there are only a few, ready to implement, compressed air powered engine solutions available on the market. A major advantage is the ability to convert internal combustion engines to run with compressed air. The study provides a literature review of solutions, focusing on a multifaceted analysis of pneumatic drives. Increasing vehicle approval requirements relating to their emissions performance are encouraging for the search of alternative power sources. This creates an opportunity for the development of unpopular propulsion systems, including pneumatic engines. Analysing the works of some researchers, it is possible to notice a significant increase in the efficiency of the drive, which may contribute to its popularisation.

    Opis:
    The analysis of driving tests repeatability is an important issue in terms of measuring the parameters determining operating conditions of the engine and the vehicle. Most of the typical tests apply to powertrains systems or entire vehicles. This paper undertakes the issue of practical evaluation of the tests repeatability on test stands equipped with a hybrid drive system. A high reproducibility of driving tests using only the accelerator pedal settings was obtained. Also a significant battery charge level influence on the repeatability of selected parameters of the hybrid drive system in driving tests was proved. Such dependence on the level of battery charge was demonstrated for the vehicle speed, combustion engine speed and the degree of the combustion engine utilization, affecting at the same time the operating conditions of the electric motor.
    Analiza powtarzalności testów jezdnych jest zagadnieniem istotnym w aspekcie pomiarów wielkości określających warunki pracy silnika i pojazdu. Większość typowych testów dotyczy badań silników lub pojazdów. W pracy podjęto tematykę praktycznej oceny powtarzalności testów badawczych na stanowisku wyposażonym w układ napędu hybrydowego. Uzyskano dużą odtwarzalność testów jezdnych przy wykorzystaniu jedynie nastaw pedału przyspieszenia. Wykazano duży wpływ stopnia naładowania akumulatora wysokonapięciowego na powtarzalność wybranych parametrów układu napędu hybrydowego w testach jezdnych. Zależność od stopnia naładowania akumulatora wykazują: prędkość pojazdu, prędkość obrotowa silnika spalinowego oraz stopień jego wykorzystania, co jednocześnie wpływa na warunki pracy silnika elektrycznego.

    Strict emission standards mean that the internal combustion engines used in means of transport must meet the standards for the emission of harmful compounds. For this reason, there is an increase in the use of alternative sources of propulsion, including rail transport. The article presents unconventional solutions of drive systems in rail vehicles using hybrid systems and fuel cells. The concept of the realizing project of a specialpurpose rail vehicle, which is to be able to be driven from three different sources, was presented. Considerations concerning the selection of the internal combustion propulsion system, which is to be used as an auxiliary in the vehicle, are described. The possibilities of installing the power unit on the vehicle were also presented.
