Item 160 km/h on the Highway(University of Zilina, 2016) Rievaj, Vladimír; Mokričková, LenkaThe speed limit on the highways of Slovak Republic is 130 km/h. It is recently considered the increase of this speed on some sections to the 1600 km/h. However this increase brings with it a substantial negative impacts. On the basis of its evaluation appears to increase this speed to 160 km/h as inappropriateItem 3D modelovanie pre potreby simulačnej rekonštrukcie pádu ľudského subjektu z výšky(University of Žilina, 2023) Kolla, Eduard; Adamová, VeronikaThe article presents the methodology for 3D modelling for biomechanical evaluation of falls from the height of a human subject. It focuses on 3D modelling as a base for numerical simulation using multibody modules in the PC-Crash simulation software. Basic steps for the creation of a 3D multibody model of the relevant building structure from a 3D point cloud are presented, as well as the procedure for the creation of a biofidelic female human body model. The multibody model of building structure and a multibody model of the human body can be in the following steps used for comprehensive parametric evaluation of possible fall scenarios using the iterative approach for convergence of trace correspondences.Item Accompanying phenomena during casting of aluminium alloys(University of Žilina, 2023) Galčík, Marek; Brůna, Marek; Medňanský, MartinAn oxide layer is formed on the surface of a molten aluminium alloy when it is exposed to the surrounding atmosphere. The oxide layer on the surface of the melt is not harmful. The problem occurs when it is entrained into the melt volume and solidifies in the casting. The paper deals with the formation of the oxide layer, its types and the formation of a double oxide layers.Item Advancements in VDL and CPDLC: revolutionizing European aviation communication(University of Žilina, 2023) Novák, Andrej; Kováčiková, KristínaThe paper is focused on the transformative impact of VDL and CPDLC on aviation safety, efficiency, and reliability. Tracing the historical evolution from radio systems to the adoption of VDL and its integration within Europe's unified airspace initiatives, this paper deals with key theories including VDL Mode 2, ACARS, Aeronautical Telecommunication Network, ADS-B, and CPDLC. Emphasizing interdisciplinary collaboration to tackle communication challenges, the paper spotlights CPDLC's evolution integrating AI, Machine Learning, cybersecurity protocols, and technological integrations like 5G and satellites. Human-Computer Interaction research underscores user-friendly CPDLC interface designs. Methodologies encompass operational analyses, communication protocols, avionics technologies, and usability testing. Aligning with the Single European Sky initiative, the integration of VDL and CPDLC anticipates emerging trends while addressing challenges like interoperability, training complexities, and cybersecurity vulnerabilities through proposed solutions. The paper offers a comprehensive understanding of advancements shaping the modern aviation communication landscape.Item THE ADVANTAGES OF PLANT PROTECTION BY USING UAV OF AIRCRAFT CONFIGURATION AND ULV TECHNOLOGY(University of Zilina, 2019) Yun, Gennadiy; Pederiy, Yuri; Gnashuk, AndreiThe article deals with the design of agricultural UAVs. In recent years, various agricultural UAVs (mainly the copter configuration) have been developed for processing small fields using the method of ultra-low-volume spraying. The proposed project of an agricultural UAV aircraft configuration has several advantages especially when used on large fields. Due to the high flight speed, high payload and the duration of flight time without refuelling, this aircraft has a fairly high performance in the process of protecting plants from diseases and pests. In addition, a relatively simple infrastructure, based on the years of experience in the use of manned aircraft in agriculture, allows, by analogy, to develop an unmanned aviation system for agricultural purposes. Flights are currently underway to test UAV control systems when manoeuvring at low altitudes near obstacles.Item Aerodynamic optimazation of long endurance UAV wing(University of Žilina, 2024) Jackuliak, Jakub; Dianovský, Róbert; Bernátová, BarboraWith recent growth in UAV sector, UAVs are progressively used more than ever before. With growth of UAV use is closely tied growth of possible uses of such aircraft. Missions conducted by any aircraft put requirements on the aircraft itself. This leads to necessity of optimization of aircraft for specific mission profile to maximize its mission efficiency. This article focuses on optimization of UAV wing for long endurance flight.Item AEROjournal - celé číslo 1/2019(University of Zilina, 2019) Novák, Andrej; Lusiak, Tomasz; Kováčik, Ľubomír; Škultéty, Filip; Čerňan, Jozef; Rostáš, Ján; Bugaj, Martin; Pecho, Pavol; Lusiak, Tomasz; Janovec, Michal; Urminský, Tomáš; Škvareková, Iveta; Kandera, Branislav; Ažaltovič, ViliamItem AEROjournal - celé číslo 1/2020(Žilinská univerzita v Žiline, 2020)Item AEROjournal - celé číslo 1/2021 (University of Žilina, 2021)Item AEROjournal - celé číslo 1/2022(University of Zilina, 2022)Item AEROjournal - celé číslo 1/2023(University of Žilina, 2023)Item AEROjournal - celé číslo 1/2024(University of Žilina, 2024)Item AEROjournal - celé číslo 2/2019(University of Zilina, 2019) Kováčik, Ľubomír; Novák, Andrej; Lusiak, Tomasz; Škultéty, Filip; Poljak, Jozef; Yun, Gennadiy; Pederiy, Yuri; Gnashuk, Andrei; Bartoš, Miroslav; Badánik, Benedikt; Jarošová, Miriam; Kazda, Antonín; Bugaj, Martin; Materna, MatúšItem AEROjournal - celé číslo 2/2020(University of Zilina, 2020)Item Item Item AEROjournal - celé číslo 2/2023(University of Žilina, 2023)Item AEROjournal - celé číslo 2/2024(University of Žilina, 2024)Item Aeronautical Telecommunication Network(University of Zilina, 2016) Novák, Andrej; Žáčik, NikolasThis paper summarizes the results of a study of modern telecommunication technology in the Aeronautical Telecommunication Network. The article deals with the integration of modern telecommunication technology into the still developing sector of aeronautical telecommunication.
