Opis:: Gears used for the tests may be made of metal or plastic [1, 2, 5]. The stand has been designed in an open system and it is powered by a three-phase electric motor. The control is provided by a single-phase inverter with three outputs, which provides full speed control. All components have been installed on a table equipped with T-slots in order to determine the optimal position of the drive and the tested gear. The load of the stand is realized by an electromagnetic powder brake. Load torque of the gear depends on the supplied current. During the test, you can change settings such as speed or load torque. Torque meters installed on input and output of the demonstrator let you control the work of the whole gear. Values supplied by the torque meters (torque and speed) are recorded on a computer in real time (according to PC RTC) and archived by specialized software. The software installed on your computer allows you to view results of the measurements. The possibility to control working time lets you precisely define the time intervals of various stages of the research. Using timer makes it possible to observe the current consumption of the transmission and helps to establish the research process. Thanks to data, recording you will know when the gear is damaged. Tests at this stand allow for obtaining stable working parameters, and thus for obtaining not distorted, accurate results of the demonstrator operation. Changing the gear is exceptionally simple because of the use of sliding splined connections of the couplings. Separating couplings between which the gear is situated and unlocking, the terminal allows exchanging it.

Opis:: Magnetorheological elastomers have properties that can be altered by magnetic field. Many materials were invented more than 30 years ago, but their development and improvement over the past three decades has led to new, more varied uses of these adaptable materials. The main goal of the paper is to present and investigate the application of a magnetorheological elastomer in an aviation structure. The potential advantage of this solution is a possibility to adjust the shape of the wing during the flight by altering the magnetic field strength, which in turn causes deflection of a magnetorheological elastomer. For the purpose of the investigations, an E214 aerofoil has been selected. The original, carbon composite model set a reference value of both lift and drag coefficient for an E214 profile. A thin layer of magnetorheological elastomer was placed on the upper side of the reversed wing. In order to fully understand the effect of such structural change on an aerial profile, the new research stand was designed and manufactured for the purpose of this research in the Institute of Aviation. Experiments were conducted due to evaluate the influence of magnetorheological elastomer on the overall performance. Results of investigations were presented and discussed.

Opis:: Article presents the energetic balance of small-unmanned vehicle hybrid power transmission. The vehicle equipped with series 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. Investigation was divided on two stages. At first stage generator, charging unit and battery were placed outside the vehicle. One piston power generator was feed by Diesel fuel. Fuel consumption of power generator was recorded from AVL fuel balance and energy parameters were recorded by power line analyser of BMR Company. Generator was connected to the direct current power plant. 70 Ah and 48 DC Lithium-polymer battery was charged from the power plant. After charging cycle, small water resistor was used to discharge the battery. Power parameters of discharged battery were measured. This enable to measure balance form tank to the battery. Second stage of the energetic balance determination was to measure internal resistances of vehicle power transmission from current inverter/converter connected to the engine and through the transmission up to the wheels of the vehicle. Power loss of energy at different speed of vehicle wheels without ground contact was measured in respect of power consumption. The series hybrid transmission is consider less efficient than parallel but because of specific configuration of power transmission, it was possible to reach higher efficiency

Opis:: In the paper a model test stand designed and built using original components of diesel engine 4CT90 is presented. The stand provides working conditions as close as possible to the exploitation conditions of the engine cooling system. This applies both to the intensity of heat inside the cylinders of the engine, the temperature uniformity along the cylinder axis, as well as variable-speed water pump. Research carried out on the model stand were aimed at checking the operation of the cooling intensity control with varying levels of filling of the cooling system and develop a control method of the cooling system before testing on the dynamometer stand. In addition, system operation at elevated cooling liquid pressure for the possibility of obtaining the elevated coolant temperature were checked. The influence of working conditions on the level of the temperature was also analysed. In this paper, the characteristics selected for two values of pressure, for 0.15 MPa and 0.2 MPa, and for two different values of the degree of filling of the cooling liquid were presented. During the warming-up and continuous heating of the cylinder and the cylinder head by electrical heaters, temperature and overpressure courses before and after the liquid radiator, temperature before the inlet and outlet of the liquid from the engine and the temperature at selected points inside the engine water jacket are designated. The results of measurements of the coolant pump flow at different speed water pump were also presented in this paper.

Opis:: The paper deals with the project of an electric motor with permanent magnets flux control for cars. One of the aims of this project is to test the prototype machine. According to the assumptions, this machine should have a high efficiency throughout the motor speed range and load. At the same time it should have a high starting torque and the ability to easy control of the speed of nearly 10,000 rpm. Testing of the prototype machine with such requirements means considerable demands on the test equipment. For these reasons, it was decided to build a new test stand with computer measuring system and high speed asynchronous motor fed regenerative inverter. The control of the test stand is based on the sb-RIO controller, and for measurement data acquisition system shall be responsible PXI modular systems both from National Instruments. All components of the test stand and their functions have also been described.
W pracy przedstawiono problematykę badań silnika elektrycznego z regulacją strumienia magnesów trwałych do napędu samochodów. Celem realizowanego projektu, oprócz analizy teoretycznej i budowy silnika, jest przeprowadzenie kompleksowych badań prototypu. W założeniach maszyna ta powinna charakteryzować się wysoką sprawnością w całym zakresie prędkości obrotowych i obciążeń, a jednocześnie powinna posiadać duży moment rozruchowy i zdolność łatwej regulacji prędkości obrotowej do wartości 10000 obrotów/min. Przebadanie prototypu maszyny o tak zdefiniowanych wymaganiach wymaga zastosowania odpowiedniej aparatury. Z tych względów zbudowano od podstaw nowe stanowisko badawcze z komputerowym systemem pomiarowym, w którym zastosowano, jako jednostkę napędową, wysokoobrotowy silnik asynchroniczny kontrolowany przez regeneracyjny przemiennik częstotliwości ze sterowaniem DTC firmy ABB. Sterowanie pracą stanowiska oparte zostało na kontrolerze sb-RIO, a za akwizycję danych pomiarowych odpowiada modułowy układ PXI - oba układy firmy National Instruments. W pracy przedstawiono wszystkie składniki tego stanowiska i omówiono ich działanie.

Opis:: The article contains results of a conceptual work and research which develops a semi-active suspension of the 2S1 caterpillar platform. The results are collected on designed and built test stands and used in three alternative models of the platform suspension system. The first one is based on the existing construction of the platform. The other two have been modernized by using new solutions in the tracked vehicles suspension technology associated with a torsional spring element. The authors assumed simulation conditions for straight line driving while the model overcomes an obstacle in one track. The results of simulations are compared and analyzed to improve parameters of the vehicle suspension.

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 paper presents an outcome of load carrying tests of gears in an aircraft gearbox demonstrator made of ABS B601polymer by means of INSPIRE D290 device. These tests checked an influence of an additional number of contours in gear models on durability of cooperating wheel pair during stand tests. The CAD models of the gears for stand tests were made in Autodesk Inventor program and were used as a base for making physical models. Therefore, Inventor files were exported to STL format. The following stage of data preparation was made in Model Wizard. The gears for stand tests were made by means of MEM method on INSPIRE D290 printer. Unlike most devices, this printer makes it possible to control not only the density of the filling in a model, but also to increase the number of contours. ABS polymer was chosen to make the gears. The choice was due to its good properties and because it is commonly used and also because it was possible to make the parts of the gearing at the Rzeszow University of Technology. Subsequently the gear pair was fixed on a test stand. The stand was designed in an open system. It was powered by a three-phase 0.75 kW electric motor. The control was provided by a single-phase inverter. Load on the stand was provided by an electromagnetic powder brake. This paper is a part of implementation of the research task number 4 „Development of a new, simpler and cheaper toothed gear in place of complicated and expensive planetary gears” of the project „Modern material technologies in aerospace industry."

Opis:: The paper proposes a stand that can be used for the testing of propellers and rotors with diameters up to 2.4 m, whose areas of application encompass, inter alia, vertical takeoff and landing (VTOL) type multi-rotor drone systems. The presented solution allows for testing propellers in systems with electric motors. To a certain extent, it is possible to achieve an increase in the measuring range by changing electric motors, power supply systems and measuring sensors. The paper presents several solutions for test stands that can be applied in the testing of propeller parameters, and commercially available propellers have also been deployed in the testing routines. The paper briefly presents the concept of the stand and its design, as well as the principle of operation and structural calculations underlying its functioning, after which the numerical model of the test stand is explained. The article then demonstrates the particular results of the test stand model’s functioning using the EMRAX 188 electric motor and two propellers, namely a commercial Aerobat propeller and a composite propeller designed and manufactured at the Łukasiewicz - Institute of Aviation. Thus, the paper presents both the theoretical results that follow from the model and the results of experimental research.

Opis:: The methodology of research and the inspection of the main transmission gearboxes of multi axles armoured vehicle ROSOMAK under operating conditions are described in this article. Tests are carried out on the bench to allow force transmission changes to the extent similar to the loads that occur during vehicle operation. Transmission gear boxes are driven by an internal combustion engine 359 through a reducer (standard engine gearbox). This reducer increase torque and decrease shaft speed similar to condition in the vehicle. On the other side of the transmission, multiplying gearbox coupled with a brake dynamometer were placed. It increases speed according to requirements of the work field of the dynamometer W-230. The combustion engine made possible to measure vibration of transmission gearboxes under the high torque. The torque is greater than obtainable by using electric motors. The value of the inertia moment loading axle shaft was determined using a simplified kinematic diagram. During the tests, vibration were measured at selected points of the housing using different methods of attachment of vibration transducers. First, the screw for assembling the vibration sensor was glued to the hull of gearbox. Second, the sensor was connected with gearbox by permanent magnets. Third, the sensor was used as a hand probe. The results of vibration measured by these methods were compared. Temperature of the gearbox was also measured by using thermocouples and thermovision methods. Selected results are presented and analysed of vibration transmission and its temperature at selected working conditions.
