    Prevádzkovo-technické východiská koncepcie BWB letúnov
    (University of Žilina, 2025) Kováčová, Simona; Škultéty, Filip
    The Blended Wing Body is a revolutionary aircraft concept with the potential to surpass present-day conventional aircraft regarding aerodynamic efficiency, and to lower the environmental impact of the aviation industry. However, despite over thirty years of contemporary research, there is still no operational blended wing body airliner, suggesting the presence of multiple unresolved issues pertaining to this design. This article investigates various operational and technical aspects related to the design process of BWB aeroplanes and their influence on the resulting aerodynamic performance. The aim of this work is a multidisciplinary analysis with focus on aircraft structure, operational safety and ultimately on the inter-comparison of required and achievable flight characteristics.

    Polymorfné konštrukcie ako súčasť riadenia letúnov
    (University of Žilina, 2025) Schwarz, Michal; Škultéty, Filip
    Goal of this work is to find out whether morphing wing configurations are a viable option for flight controls such as elevators, flaps, ailerons etc. This work is divided into 3 sections. First section is about general research of conventional wing constructions, materials used in aircraft and mechanisms used to actuate flight controls. Second section looks into construction of morphing wings, viable materials for these constructions, mechanism used to actuate them and finally designing a functioning morphing wing based on previous research. In final third part we are going to compare morphing configuration against conventional solutions used on aircraft today in CFD simulations as well as in a wind tunnel and compare the results gained by these simulations.

    Konštrukcia bezpilotného letúna s možnosťou VTOL
    (University of Žilina, 2025) Berki, Július; Škultéty, Filip
    Article focuses on the design, construction, and testing of an unmanned aerial vehicle (UAV) with vertical take-off and landing (VTOL) capabilities that does not require thrust vectoring mechanisms. The goal of the work was to create a simpler and more reliable prototype compared to most UAV convertiplanes, which use mechanisms for thrust vectoring, while being built from cost-effective materials. This UAV may be intended for the public as a DIY project. The article providing a design of the aircraft, including aerodynamic parameters, material selection, and electronic components. Airflow simulations using specialized software tools for aerodynamic analysis were applied during the development process. Experimental testing of the prototype was conducted in real-world conditions, including vertical take-offs and landings on a specially designed test polygon, where stability and hovering flight characteristics were monitored. Based on the results from the experimental tests, the success of the design was evaluated by the critical approach, which then led to the formulation of recommendations for improving the aircraft's design. The article also offers a guide to building DIY UAVs and provides a basis for further research in this area.

    Identifikácia prekážok v okolí letiska lzzi prostredníctvom leteckého laserového skenovania
    (University of Žilina, 2025) Švancár, Denis; Škultéty, Filip
    The article focuses on the identification of obstacles in the vicinity of Žilina Airport (LZZI) by means of airborne laser scanning technology. The main objective of the thesis is to identify the limitations of this technology in determining the location and height of potential obstacles in the vicinity of Žilina Airport that could threaten the safety of air traffic. The subsequent values found were compared with the requirements set by the International Civil Aviation Organization (ICAO). The results showed that the LiDAR technology enables satisfactory identification of obstacles interfering with the airport obstacle planes. A number of vegetation obstacles were identified that interfere with the obstacle planes of Žilina Airport. The accuracy of the data collection met the requirements set by ICAO PANS-AIM for the areas surrounding the airport. The work confirmed the time efficiency of airborne laser scanning when used over vegetation obstructions in the wider vicinity of the airport.
