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:: 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:: 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 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:: This paper describes the conception of an individual personal transport vehicle. The conception of the vehicle is based on a mechanical structure of a bike and on a pneumatic engine as equipment of power support. The research was done as an analysis of existing vehicles with main or supporting gas power systems. In the research the expectations of users, technical resources as well as known constructions were taken into account. At the beginning, the technical properties of known methods and modern vehicles available for individual personal transport of people were reviewed. Next, some vehicles which can meet economic, ecologic and environmental criteria were identified. Finally, the authors proposed usage of extremely small and light-weight vehicles. It appears that the smallest, lightest and most economic construction of vehicles should be modeled on the bike. For power convenience on uphill roads compressed air as a supporting power factor was proposed. It also implied the possibility to use supporting power system as main power engine. However, the economic storage and management of compressed gas required optimization system of gas usage. This optimization depends on pulse wide modulation of air valve flow and possibility of air compression. Air compression is possible by driving downhill or on fixed vehicle by human muscle power. Those circumstances warrant to name such power system a hybrid pneumatic propulsion.

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:: 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.
