Aerodynamic characteristics of airfoils
Foltýn, Pavel ; Cejpek, Jakub (referee) ; Koutník, Tomáš (advisor)
This bachelor´s thesis describes an influence of geometric characteristics of an airfoil on its aerodynamic properties. The first part of the thesis defines airfoil, describes its geometric characteristics, emergence of aerodynamic forces and convection around airfoil. The second part deals with influence of profile geometry on aerodynamic properties of airfoils. It is shown on NACA four and six digit profiles, in their buoyancy and moment lines and polars. The last part deals with wind tunnels and measurement in them. The thesis focuses on forces and moments measurement by force balances and static and total pressure measurement. Velocity measurement is focused on the laser Doppler velocimetry, on the hot-wire velocity probe and PIV method. Very briefly selected flow visualization methods are shown there. Comparison of profile characteristic obtained by measuring in wind tunnels and numerical simulation in Xfoil program is also shown there.

Determination of geometric characteristics of curved beam
Foukal, Jakub ; Houfek, Martin (referee) ; Benešovský, Marek (advisor)
This bachelor thesis focuses on creating a algorithm for determining geometric characteristics of curved beam. In the first part, formulas are taken from technical literature. These formulas are then modified and used for implementation of algorithms. In the following section, there are two algorithms for determining the curvature of a curved beam and comparison between their calculated values. The concluding part focuses on an algorithm for calculating the cross-section characteristics from random image format. The algorithm of cross-section characteristics is analytically verified.
