    Design of lubrication system, design of motor bed, selecting of propeller for aircraft piston engine
    (University of Zilina, 2021) Suk, Michal; Čerňan, Jozef
    I will briefly address the three orientations of my paper in this scientific article. I will not go into details in the article. In the first part I will briefly describe the design procedure of a piston engine lubrication system, the requirements that a lubrication system should meet with respect to different types of piston engines and their focus, elements of the lubrication system and the properties of oils as lubricating fluids.In the next part I will describe the types and constructions of aircraft engine beds, technical requirements for aircraft engine beds and individual loads that the aircraft engine bed must withstand. In the last part I will focus on aircraft propellers. I will explain the basic principle of the propeller, the individual rules for selecting a propeller for a piston engine, safety requirements for an aircraft propeller and the dividing of basic types of aircraft propellers for aircraft piston engines.

    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.
