    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.

    Štúdia spolupráce energetického úložiska z batérií druhej životnosti a fotovoltaickej elektrárne
    (University of Žilina, 2023) Liška, Martin; Štrkolec, Juraj; Matušov, Jozef; Havlíček, Tomáš; Louvar, Stanislav
    The aim of the simulation is to optimize the parameters of the battery storage system using battery cells from electric cars in cooperation with a photovoltaic power plant at the point of connection with a reserved input power of up to 100 kW. The analysis is performed in the Python programming environment, where all algorithms and calculations are implemented. The source codes of the simulation contain historical data of specific PV power plants.

    3D modelovanie pre potreby simulačnej rekonštrukcie pádu ľudského subjektu z výšky
    (University of Žilina, 2023) Kolla, Eduard; Adamová, Veronika
    The 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.

    Development of the design of an experimental long-range fixed wing uav
    (University of Žilina, 2023) Suk, Michal
    The goal of the article is the design and assembly of a flight-capable platform for testing an experimental hybrid drive developed within the grant project. The input for the entire work is designed for the highest take-off weight of 10 Kg and a pair of driving electric motors with a thrust of 5 Kg each (49,05 N). The content of the article includes basic theory, analyses, simple structural calculations and design methods, the design itself, construction methodology and work results. Analyzes in the article include analyzes of currently used types for the design and construction of hybrid unmanned aerial vehicles and analyzes of materials used for UAV structures with a piston propulsion unit, on the basis of which the design and construction of the UAV was proposed. As part of the design, the construction and design are recalculated and simulated both aerodynamically and strength-wise. Several software were used in the design and simulations: AutoCAD Inventor for modeling and strength analyses, Autodesk CFD for airfoil simulations and XFLR5 for the aerodynamics simulation of the UAV design. In the practical part, the production methodology is described in detail and illustrated with original photographs.

    Calculation and simulation of the parachutist's movement from the jump from the aircraft to landing on the ground
    (University of Zilina, 2021) Beník, Martin; Kováčik, Ľubomír
    In this article, we focus on the movement of the parachutist from the jump from the plane to the impact on the ground. By creating a mathematical model based on Newton's second law, we create simulations, based on which we can determine whether the movement of a parachutist after jumping from a plane is a "free fall", or whether the action of forces and his position in the air affects the direction of his flight.
