Opis:: Hybrid energy generation incorporating the renewable energy sources is gaining recognition and importance in the world. Institute of Aviation has thus decided to open a project: construction of a portable energy source container, incorporating modern hybrid solutions. In this article, the basic approach to creating a model of such a hybrid energy source is described: an initial scheme and composition of a portable container hybrid energy source, consisting of a wind turbine, photovoltaic array, battery bank and a backup diesel generator is proposed. A preliminary model of the portable hybrid energy source container, with two separate control system schemes, was created in TRNSYS Simulation Studio software and is presented in this article. The data acquired from the TRNSYS simulations of the hybrid source container are gathered and organized, and then presented and analysed. From a theoretical point of view, it is interesting to see how the renewable based system characteristics differ with changing weather conditions, and how supporting the load is being switched between the renewable system and the diesel generator. From a practical point of view, it will be interesting to see the diesel fuel savings, and related to them lowered exhaust gases emission, coming from reduced diesel generator operation times. A problem of reducing emissions and fuel consumption, and matching the operation of energy generation to consumer need more flexibly that is offered by a hybrid source is particularly important.

Opis:: A hybrid electric vehicle is a vehicle which combines a conventional propulsion system with an on-board rechargeable energy storage system to achieve better fuel economy than a conventional vehicle without being hampered by range from a charging unit like a battery electric vehicle, which uses batteries charged by an external source. Hybrid vehicles have a conventional engine (gasoline or diesel) as well as a large battery and an electric motor, so that the wheels of the vehicle are driven by both an internal combustion engine and an electric motor. There are various arrangements for these two motors. The article presented the construction solutions and parameters of this hybrid also included information about basic actions of hybrid motor system in the scooter, with two different sources of power. Designed and carried out motor system in scooter included internal combustion engine and electric engine installed in wheel. Explained how accumulator charging system can charge batteries from the gasoline motor while scooter is traveling at normal road speeds and also how can be connected to a standard 230V. Showed how calculate circle of power between engines with take advantage of microcontroller and how special microcontroller system can control all function in scooter (for example: active source of power, speed, brakes, lights, level of voltage). Explored how energy recuperation system is working during braking of machine. Article included also some important information about few achievements like increasing of vehicle range, bigger stock of power, reduction of gas consumption and reduction of CO2 emission to atmosphere.

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:: The structures of modern traction vehicles are based on new generation devices. Technical progress within the field of power transmission concerns such elements as sources of power supply, electric devices and energy electronic solutions in power transmission systems. The prototypes of traction vehicles being currently drawn up are hybrid vehicles using different kinds of sources of power supply ofpower transmission systems, the most important of which are combustion engines, contact systems, supercapacitors (ultracapacitors), accumulators and fuel cells. Main engines are usually electric machines. In energy electronic starting systems it is permissible to use all kinds of main electric engines, for example, direct-current motors (inline engines, commutator motors with permanent magnets or non-commutator motors) or three-phase motors of alternating current (induction and synchronous). This means a complete change of rules in energy managing in a vehicle. Sources of energy can have the function of basic power supply (contact system, combustion engine or combustion cell) or the function of power supply support (supercapacitors, accumulators or fuel cell). New functions of drive operation will be available, namely, leveling of basic power supply load, recuperation of braking energy of the whole train set, driving at the temporary disconnection of basic power supply (short-term application of accumulator as basic power supply). Each of the above functions can contribute to the improvement of watt-hour efficiency of the system or to prolonging the range of driving. Therefore, it is necessary to undertake research on new generation power transmission systems. Research tasks focus on measurement of state variables of a drive, analyses of traction signals, modeling of drive operation in the conditions of driving cycle realization, verification of a model, drawing up a strategy of energy management in order to achieve the best watt-hour efficiency and the range of driving. In the article presented, sample results of researches on applications of hybrid power transmission systems conducted in various national research centers will be demonstrated. They concern both theoretical research (model simulation) and prototype research. The conception will be presented of a laboratory station for conducting research on modern sources of power supply and drives, which is currently being built at the Faculty of Transport of Warsaw Polytechnic at the Division of Exploitation of Tracking Systems and Electric Equipment in Transport.

Opis:: In this article, results of experimental studies concerning the relief of a city car electric drive by means of hydrostatic drive support are presented. Experimental studies were performed using a laboratory station built for this particular purpose. Studies of basic properties of elements of hydraulic system and resistances in the mechanical system were performed. The results of experimental studies of a chosen sub-assembly of hydrostatic drive (i.e. hydro-pneumatic battery) are given. The resistances within mechanical system (flywheel) were determined. In the considered hybrid drive, electric drive is cyclically supported by hydrostatic drive during acceleration or regenerative braking of the vehicle. The results of experimental studies presented in this article were obtained on a designed and built laboratory station representing a model of a lightweight delivery van for city traffic and equipped with the studied hybrid drive. The obtained results suggest that there is a possibility considerably to increase the effectiveness of energy conversion in the electric drive of the vehicle by means of hydrostatic support. By applying the hydrostatic support in the electric drive, the load on the electric battery decreased, which positively influences the length of operation time.

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:: In the article, a study of conversion of energy in a hybrid (electro-hydrostatic) drive of a utility van intended for city traffic is described. In this hybrid drive, the electric drive is periodically accompanied by hydrostatic drive, especially during acceleration and regenerative braking of the vehicle. We present a mathematical model of the hybrid drive as a set of dynamics and regulation equations of the van traveling at a given speed. On this basis, we construct a computer program, which we use to simulate the processes of energy conversion in electro-hydrostatic hybrid drive. The main goal of the numerical simulation is to assess the possibility of reducing energy intensity of the electric drive through such a support of the hydrostatic drive. Our results indicate that it is possible to significantly increase the efficiency of energy conversion in the electric drive by support of the hydrostatic drive. In the article, chosen results of simulation studies for multiple starting and braking the car are given, and they show a 30% decrease for energy drawn by the hybrid drive, compared to solely electric drive.
