Front Wing for Formula Student
Vrubel, Vít ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
This work deals with the verification of the design of the front wing on the Formula Student car. The work is divided into three parts. In the first, a search of the wings used in the Formula Student competition is performed. The second part is devoted to the experiment and the last part is devoted to CFD calculations and comparisons with measured values. Computations were done on computational resources supplied by the project „e-Infrastruktura CZ“ (e-INFRA LM2018140) provided within the program Projects of Large Research, Development and Innovations Infrastructures. Computational resources were provided by the ELIXIR-CZ project (LM2015047), part of the international ELIXIR infrastructure.

Wind tunnel measuring equipment calibration
de Boer, Hendrik ; Grim, Robert (referee) ; Matějů, Jiří (advisor)
V této diplomové práci bylo zkoumáno téma kalibrace zařízení a sekcí ve vztahu k aerodynamickému tunelu na brněnském institutu leteckého inženýrství. Přístroje používané v aerodynamickém tunelu jsou kalibrovány a jsou popsány a provedeny kalibrace sekcí na testovací sekci. Kalibrační listy a šablony sestav jsou vytvořeny za účelem zjednodušení budoucích procesů. Nově kalibrovaná sestava se používá k provádění měření síly a probuzení na modelovém voze, která jsou porovnána s předkalibrací měření, aby dále ilustrovala užitečnost kalibrací.

Static analysis of the lookout tower
Šoupalová, Kristýna ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
This bachelor’s thesis deals with the static analysis of the steel construction of the lookout tower in the shape of a helix. Two 3D models, which differs in the way the columns are modeled, were made with RFEM 5.25 software by Dlubal company. The models are loaded with the calculated loads and afterwards the results of both models are compared. There are also a third 3D model, which includes surfaces. This model is put to a wind tunnel through Dlubal RWIND software. Then the comparison of the wind loads calculated according to the valid standard and the RWIND results is made.

Air flow measurement through compact heat exchanger in wind tunnel
Žůrek, Michael ; Vondruš, Jan (referee) ; Šebela, Kamil (advisor)
This thesis describes Formula Student competition, overview of used aerodynamic devices, placement of compact heat exchangers on these monoposts and current monopost Dragon e2. Next section examines commonly used compact exchangers and their aerodynamic drag, mainly caused by angling and ununiform flow. Subsequently is described the process of preparation, measurement in wind tunnel and measuring devices. An algorithm was created and described, which was used for evaluation of measurement, influence of some factor was commented. On the right-side compact exchanger, methods of measuring were compared, namely pneumatic probe, pressure difference and turbine anemometer. On left side exchanger were observed influence of various aerodynamic elements. Lastly alternative position behind vehicle rear axle was measured.
