Opis:: This article introduces the synthetic material for future Unmanned Aerial Systems (UAS). The issues raised in it mainly concern the autonomy of these systems, applied design, propulsion systems, equipment and development trends in the UAS market. In addition, it presents global trends regarding methods of use, application and use of Unmanned Aerial Systems. Observing the growing realm of UAV in military actions it is expected to be the development of autonomous platforms implementing transport and combat missions. Increasingly used UAV platforms in military action jointly with manned platforms (mix formation) and in mixed formations of unmanned (UAV swarms differently equipped). Usage of unmanned aircraft in the civil sphere is very extensive and includes rescue operations – coordination and support, research – geodetic and cartographic, environmental protection, agriculture – monitoring of farmlands, natural resources, system warning of natural disasters; monitoring traffic – map navigation system; taking pictures and videos; data transfer.

Opis:: Contemporary battlefield is more and more demanding environment after all for soldiers but also for their equipment and machines that assist them. Looking at the last Lessons Learned experience we can conclude that the most dangerous threats met during last asymmetric warfare were Improvised Explosive Devices (IEDs). Therefore, the main focus is being done to equip UGVs with efficient engineering equipment that allows operating very quickly in very dangerous environment being exposed to health risks and loss of human life, within more and more sophisticated engineering support missions with special regard just to EOD/IED missions. The concept of such an engineering robot design is described in this paper. The EOD/IED mission support engineer robot, the attachments of the EOD/IED mission support engineer robot, removal of car bombs by means of the robot’s attachments, the EOD/IED mission support engineer robot’s ability to overcome terrain obstacles, the mission support engineer robot’s remote control panel are presented in the paper. Technological and Operational Problems Connected with UGV Application for Future Military Operations was held in Rzeszow, Poland on 20-22nd April 2015.

Opis:: Navigating vehicles over difficult terrain requires a drive system ensuring high mobility. It is particularly important in the case of unmanned ground vehicles. It is often not realized that a vehicle occupant frequently plays the role of a multi sensor, highly effective data processor and a control system at the same time. Due to this, the abilities of an unmanned vehicle's drive system should, to the greatest possible extent, compensate for the lack of an inside operator. To achieve this, it has to ensure high precision and ease of controlling. Such possibilities are provided by electric and hydrostatic systems. At the Military University of Technology, Chair of Engineering Equipment, a test platform for an EOD/IED robot was developed. Due to its considerable weight, it was equipped with a hydrostatic drive system. The vehicle has a sixwheeled chassis and a skid steering system. The paper presents initial findings of the research aimed at determining the influence of the applied hydraulic system solution on the appearance of kinematic incompatibilities. The presented experimental research included the identification of internal resistance as well as tests on three types of surfaces.

Opis:: Concept of Operations is the first tool being used in capabilities approach to define military needs being very important task in the beginning of the Life Cycle Management process. The inputs to this process are defined based on the scenarios resulting from the Lessons Learned experience. It creates the technology needs for the new military systems and simultaneously the links between militaries, scientists, designers and producers. The success of missions at the very dynamic contemporary battlefield will heavily dependent on functionality engineering forces taking part in them after all at the very low level of command. The main task of engineering forces that are realized within the convoy protection mission aims at greater soldiers’ safety. The efficiency of convoy protection demands a systemic approach and the need to build the system of remote controlled Unmanned Ground Vehicles (UGV). The design of Improvised Explosive Devices (IED), after all their initiating systems, makes Explosive Ordnance Disposal (EOD) missions practically impossible to be realized by humans. The concept of systemic approach to use the remote controlled Unmanned Ground Vehicles for convoys’ protection based on Lessons Learned experiences is presented in this paper.

particle swarm optimization (PSO)
airfoil modelling
Opis:: Small-unmanned aerial vehicle propellers usually have a low figure of merit due to operating in the low Reynold’s number region due to their size and velocity. The airflow on the airfoil becomes increasingly laminar in this region thus increasing the profile drag and consequently reducing the figure of merit of the rotor. In the article, the airfoil geometries are parameterized using the Class/Shape function transformation. Particle swarm optimization is used to design an airfoil, operating in a Reynolds number of 100,000, which has a high lift to drag ratio. To avoid exceeding geometric constraints of the airfoil, a deterministic box constraint is added to the algorithm. The optimized airfoil is then used for a preliminary design of a rotor; given some design, constraints on the tip chord the rotor radius and the blade root chord, with parameters that achieve the highest theoretical figure of merit. The rotor parameters are obtained using a combination of momentum theory and blade element theory. The figure of merit of an optimal propeller with the same geometric parameters is then compared using the optimized airfoil and the Clark Y airfoil. The optimization is done in MATLAB while the aerodynamic coefficients are obtained from XFOIL. The results of the numerical simulation are presented in the article.

Opis:: Unmanned aerial vehicles are increasingly used in military service and in everyday life. Drones can be used for many purposes i.e. recreation, military applications or to increase the safety of citizens. Unmanned aerial vehicle can become a source of information, based on which object/operator can make a certain decisions. Unmanned aerial vehicles are increasingly used in ecological research. UAV can be capable of making sophisticated maps and may scan terrain for forest fires. They can contribute to safe infrastructure maintenance and management. Often, however, these objects being in the possession of civilians can become a source of danger and impact on privacy. It is therefore necessary to detect and recognize such objects in a real time. The aim of this study was to analyse the acoustic signal of unmanned aerial vehicle equipped with four rotating propellers – X4 structure (12000 rpm/min). The maximum speed of the object is 60 km/h and the ceiling to which it can operate flights reaches 1500 m AGL. The acoustic signal was acquired by Olympus LS11 digital recorder. Recordings were performed when the object is away from the recording equipment at the distance of 1 km. Analysis of the recorded signal can provide a significant information about the unmanned aerial vehicle. Results showed that some specific characteristic signal features are clearly visible in the signal even if the object is far away from the recording equipment.

Opis:: An unmanned aerial vehicle is a flying apparatus that does not require a crewmember on board to complete a task. Its piloting is done by means of indirect control. UAVs also have the ability to perform autonomous flight on a pre-programmed flight path. The purpose of the study was to use the unmanned aircraft "Fly Eye" by WB Electronic used by the Border Guard to patrol the state border in 103 TRA zone on the section of the Republic of Poland with the Kaliningrad District of the Russian Federation. The TRA zones constitute a specially designated area for the use of the Border Guard and the army, in order to carry out flights there beyond the scope of the pattern for training purposes and to patrol the state border. The article also contains information of the Border Guard formation and the characteristics of the unmanned aerial vehicle “FlyEye”. In order to ensure the safety of the UAV flight, the test was carried out in the TRA zone, which is used for special use for the Border Guard formation and the army.

Opis:: Do napędu bezzałogowych statków powietrznych (BSP) o masie powyżej 50 kg stosuje się przede wszystkim śmigłowe zespoły napędowe z silnikami tłokowymi. Najpowszechniej stosowane są silniki specjalnie do nich produkowane przez firmy UAV Engines i Zanzottera, ale również silniki adaptowane z lotnictwa załogowego m.in. firmy Rotax czy lotnicze wersje samochodowych silników Subaru. Przyczyny związane z zespołem napędowym i zasilanymi przez nie źródłami energii stanowią ok. 32-38 % przyczyn wszystkich niesprawności BSP użytkowanych w lotnictwie sił zbrojnych USA i Izraela. Powodami stosunkowo niskiej niezawodności zespołów napędowych bezzałogowych statków powietrznych są m.in. warunki ich eksploatacji, np. wysokie temperatury otoczenia, zapylenie powietrza, warunki sprzyjające oblodzeniu. Hałas emitowany przez zespoły napędowe ułatwia wykrycie BSP, a temperatura spalin jest wystarczająco wysoka do naprowadzenia się głowic rakiet na podczerwień. Silniki powinny być tak zaprojektowane, aby do minimum ograniczyć drgania przenoszące się na wyposażenie optoelektroniczne zabudowane na płatowcu. Produkcja silników do BSP w Polsce może nie być opłacalna, natomiast możliwa jest integracja zakupionych za granicą silników z platowcami, które mogłyby być produkowane w kraju.
The most frequently powerplants in unmanned aerial vehicles (UAVs) over 50 kg mass are powerplants with piston engines. The most popular manufacturers of such engines are UAV Engines Ltd. or Zanzottera, but also engines Rotax which are adapted from general aviation and aviation versions of car engines Subaru. Failures of powerplants are 32-38 % of all sources offailures of UAVs which are used in USA and Israel armies. Operational conditions i.e. high temperatures, dust in air, icing, are sources of low reliability of powerplants of UAVs. Noise emitted by powerplants of unmanned aerial vehicles simplifies detection of UAV. Temperatures offumes are enough to intercept infrared rockets himself. Engines should be designed for minimalize vibration level which are transfer from them to optoelectronics equipment which are on an airframe. Production of powerplants for unmanned aerial vehicles in Poland may not be worthwhile, whereas possibly are integration of powerplants with airframes which may be manufactured in Poland.

Tytuł:: A study of propeller for high altitude unmanned airplane

Opis:: Over the last 20 years, we can observe growing interest in the field of unmanned high altitude aerial vehicles. Especially the light aircrafts with electric motors become popular. The use of electricity to drive enables application of non-conventional energy sources like solar energy. The propeller remains the best propulsion system for planes powered by electricity. High altitude planes powered by propellers are able to fly over the wide range of altitude: from 0 to 25 kilometres. Such wide range of altitude is connected with variability of propeller work conditions (for example the density of the air is changing 10 times) which remarkably complicate the process of matching propeller to motor. The paper presents optimization model of propeller destined to unmanned high altitude airplane. Computational procedure deals with searching optimal distribution of lift coefficient line along the blade span of the propeller to obtain maximal efficiency for selected altitudes of flight. Genetic algorithm was used during the searching procedure. The database of optimal solutions is created as a result of computation and can be later exploited for choosing the best solution able to meet the requirements. Because the same propeller is used for take-off, climb and high altitude flight, then the airfoils of the propeller blades must be capable of operating over an extremely different flow condition caused by large change in air density. Propeller blades airfoils are required to operate within a low Reynolds number (below 105) and high subsonic Mach number (up to 0.6) flow field during high altitude flight. At low Reynolds number, the airfoils generate lesser lift and higher drags. The performance of the airfoils and consequently of the whole propeller can decline significantly. The objective is to find airfoils with good performance in all condition, which can appear during the flight, and to find the best shape of lift coefficient curve along the blade span of the propeller. That is necessary in order to obtain acceptable efficiency of the propeller for all flight conditions.

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..
