Wildfires represent a significant natural risk causing economic losses, human death and environmental damage. In recent years, the world has seen an increase in fire intensity and frequency. Research has been conducted towards the development of dedicated solutions for wildland fire assistance and fighting. Systems were proposed for the remote detection and tracking of fires. These systems have shown improvements in the area of efficient data collection and fire characterization within small-scale environments. However, wildland fires cover large areas making some of the proposed ground-based systems unsuitable for optimal coverage. To tackle this limitation, unmanned aerial vehicles (UAV) and unmanned aerial systems (UAS) were proposed. UAVs have proven to be useful due to their maneuverability, allowing for the implementation of remote sensing, allocation strategies and task planning. They can provide a low-cost alternative for the prevention, detection and real-time support of firefighting. In this paper, previous works related to the use of UAV in wildland fires are reviewed. Onboard sensor instruments, fire perception algorithms and coordination strategies are considered. In addition, some of the recent frameworks proposing the use of both aerial vehicles and unmanned ground vehicles (UGV) for a more efficient wildland firefighting strategy at a larger scale are presented.

A strong interest in highly-efficient, small-scale propeller configurations can be recognized, especially due to the currently growing number of and usage possibilities for unmanned aerial vehicles (UAVs). Although a variety of different propulsion concepts already exist on the market or are discussed in the literature, there is still a demand for a systematic investigation to compare such configurations, in particular, small-scale propellers with a fixed pitch, which are analyzed in this work. Therefore, different configurations of small-scale propellers with a fixed pitch are analyzed in this paper. They were operated as isolated single propellers and as ducted propellers in a cylindrical wing. Furthermore, due to their flight envelope, UAVs are likely to operate at highly inclined inflow conditions and even under reverse inflow. These non-axial inflow conditions have a major influence on the flow field around a propeller. In order to investigate this influence, all analyses were performed at a range of inflow angles in relation to the propeller axis from αdisc=0° to 180°.

The end of the world bipolar division has reduced the likelihood of a threat of an atomic conflict, but at the same time it has released dormant conflicts. From that time, the phenomena that are not new, but their frequency, intensity, impact on human society have caused a change in the way they are perceived. In this context it is clear, that to ensure the sovereignty of the European airspace and specifically the one of the Slovak Republic, as a member of NATO, is the first priority task of the Air Force missions. To accomplish this, there will be significantly increased the requirements for processes automatization within Air C2 systems, in order to keep the necessary level of interoperability and to utilize and exploit both combat and reconnaissance unmanned aerial vehicles.

In the autumn of 2020, during the Six-Week War in Nagorno-Karabakh, the main attention of most Russian and Western experts was focused on the topic of gaining air supremacy achieved by Azerbaijan with the help of Israeli and Turkish-made unmanned aerial vehicles. The author of the article does not dispute the high effectiveness of the combat use of the Bayraktar TB 2. He seeks to draw attention to other reasons for the defeat of the Armenian armed forces. First of all, they were not ready for mobilization deployment. The degradation of the mobilization apparatus and the general inattention of the Armenian leadership to the problem of strategic concentration is difficult to explain only by the systematic underfunding of the army caused by economic difficulties. In recent years, Armenian generals and politicians have been recklessly resting on the laurels of the last victory and did not believe in the seriousness of Azerbaijan’s intentions to retake Nagorno-Karabakh.

The disordered urban growth that may favour the emergence of the Aedes aegypti mosquito in cities is a problem of increasing magnitude in middle- and high-income countries in the tropical part of the world. Currently, the World Health Organization (WHO) considers the control and elimination of Ae. aegypti a world-wide high priority as it is the main vector of many rapidly spreading viral diseases, dengue in particular. A major difficulty in controlling the proliferation of this vector is associated with identification of the breeding sites. The use of Unmanned Aerial Vehicles (UAVs) can be an efficient alternative to manual search because of high mobility and the ability to overcome physical obstacles, particularly in urban areas where it can offer close-up images of potential breeding sites that are difficult to reach. The objective of this study was to find a way to select the most suitable UAV for the identification of Ae. aegypti habitats by providing images of potential mosquito breeding sites. This can be accomplished by a Multiple-Criteria Decision Method (MCDM) based on an Analytical Hierarchy Process (AHP) for the evaluation of weights of the criteria used for characterizing UAVs. The alternatives were analyzed and ranked using the Fuzzy Set Theory (FST) merged with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The methodology is explained and discussed with respect to identification and selection of the most appropriate UAV for aerial mapping of Aedes breeding sites.
