With the increasing incorporation of new technologies into everyday life, unmanned aerial vehicles (UAV) have found, in addition to entertainment, also use in practice. The article is focused on optimizing and increasing the efficiency of UAV use in the “Search and Rescue” process. Different search situations, such as rugged terrain, outdoor temperature, area of search, require different procedures when using UAVs. In the research, the authors compared different infrared camera mount settings for specific situations along with different flight path arrangements during a UAV rescue mission. The outcomes are recommendations and a proposed methodology for more effective use of UAVs with thermal imaging in practice, which will help to more quickly locate the person or object sought.

As in commercial aviation, military aircraft typically use gas turbine engines for propulsion. Regardless of the actual output being thrust or shaft power, each type employs similar working process to produce high energy gasses. Although they are more tolerant to different fuel grades, traditionally jet fuel has been utilized in the past decades. In the recent years, due to emerging problems affecting fossil fuels several alternatives have been developed, but only a few competitors have remained that offer basically equal characteristics in contrast to conventional fuel. According to global trends in aviation, the National University of Public Service has also decided about the introduction of alternative fuel for the companies of state aviation. The main aim of this paper is to develop an advanced data acquisition system for the turbojet test bench that makes it possible to collect more sophisticated data about engine behavior with different fuels. The improved system is based on a completely new DAQ hardware specifically chosen for the given test bench environment and the choices were based on experiences with previous system components. As the original operating software was written in LabVIEW, this did not require significant rework to make it compatible with the new hardware, however, the necessary changes will be discussed here as well.

Many innovative technologies are applied in the tire industry to increase tire kilometrage. In addition to technologies for increasing rolling resistance and wet grip, eliminating tread slip, monitoring tread wear due to sensors, it is possible to add to this group also RFID technology. The forecast for the global RFID market has an upward tendency. The main goal of the manuscript is to present knowledge for the design of the concept of intelligent transport with an emphasis on intelligent tires with embedded RFID tags.

Achieving high requirements for the safety and comfort of passengers and crew of modern aircraft requires the improvement of environment control systems, which are designed to create and maintain standardized air parameters (pressure, temperature, relative humidity, air velocity, etc.) in the pressure chamber.To solve such problems in joint hydraulic and thermal calculations, special software systems are used to replace real complex systems and structures with structural diagrams of the corresponding mathematical models. However, it should be borne in mind that one-dimensional software systems cannot take into account the effects of the distribution of temperature and air pressure, taking into account the three-dimensional geometry of the passenger compartment or cockpit. Stagnation zones or deterioration of comfort conditions due to the uneven distribution of air parameters near the passenger are also possible. To solve the problem of estimating the distribution of air parameters near passengers, computational fluid dynamics methods (LOGOS, ANSYS CFX, Fluent, Star CCM+) are used to obtain a spatial distribution of the desired parameters and improve passenger comfort. Thus, to improve the quality of calculations and optimize the design of the environment control system, the interaction of one-dimensional and three-dimensional software systems is required. To implement the interaction of software systems, an example of data exchange (flow rate, temperature) was considered to maintain a given temperature in the cabin. In the SimInTech software package, a model of an air-cooling installation with the ability to change parameters was implemented and automatic equipment was prescribed to set the flight mode and operation algorithms of the dampers. In the three-dimensional software complex LOGOS, a calculation model of the cabin was prepared. The calculation of the cabin takes into account heat from passengers and changes in the parameters of moist air. The interaction of software systems has shown the possibility of increasing the speed and quality of calculations by detailing the results in the areas of interest by applying a three-dimensional code and reducing the calculation time of complex schemes by using a one-dimensional code. The solution to this problem will improve the quality of the calculations, which is necessary to optimize the design of onboard aircraft systems.

The COVID-19 pandemic outbreak has affected all sectors worldwide including aviation industry and it will take years to return to pre-crisis levels. Thousands of jobs have been lost due to the shutdown. The traffic reduction has far exceeded the level observed in events such as terror attacks of 11. September 2001 and SARS. In the course of June after months of grounded planes and thousands of cancelled flights, several European airlines are restarting their routes. However, the recovery is proceeding at a slower pace. According to ACI Europe a full recovery in passenger traffic to 2019 is now expected for 2024.

Centrifugal compressors are widely used and stability is the key factor. At low mass flow rates different instabilities can occur from which the most dangerous is surge. In contest to conventional passive surge avoidance systems which work with reduced efficiency and have limitations up to date surge suppression systems offer broader operating range and excellent dynamics. The aim of this paper is to develop and simulate linear quadratic regulator for BLDC controlled compressor. The BLDC was tested with different disturbances for the compression system and the result show that the BLDC was able to stabilize the compressor in a significantly road range than its original characteristic.
