Design of Roof Wind Power Plant
Augustová, Andrea ; Křenek, Ladislav (referee) ; Sládek, Josef (advisor)
Topic and aim of my bachelor thesis is research and design of rooftop power plant cover in accordance with technical, aesthetic and ecological requirements. The aim is to create a cover, which will be minimalistic and modern, won’t be a disturbing element in urban areas and its shape will increase the efficiency of the wind turbine.

Aerodynamics of axial wind turbines
Dubnický, Ladislav ; Pospíšil, Jiří (referee) ; Škorpík, Jiří (advisor)
Nowadays, the climate change issue is becoming more and more actual in our society. Increase of the average temperature on Earth in a couple of degrees could have catastrophic consequences. One of the possible solutions seems to be renewable energy sources as photovoltaics, biomass of water and wind energy. This thesis deals with the aerodynamics problems of wind energy source. Wind turbines transform kinetic energy of wind to mechanical power. The efficiency is physically limited to 59,26 %, but in reality, it is getting around 45 %. This is caused by three biggest losses inducted in wind turbines as wake losses, losses due to finite number of blades and drag losses. Based on analytical relationships and including these three losses the aerodynamics blade design is conducted. Later, the numerical simulations show higher values of drag and lower values of lift force on airfoil compared to analytical calculation. In fact, percentage deviations are acceptable and to conclude, the numerical analysis was able to relatively accurately simulate force action of free stream velocity on the blade.

The beginnings of automotive aerodynamics
Sunek, Ondřej ; Vančura, Jan (referee) ; Čavoj, Ondřej (advisor)
This bachelor thesis is concerned with charting the early phase of development of automobile aerodynamics around the first half of the 20th century. Further on, it describes some procedures which were used for designing of each car and the circumstances that led to the design of breakthrough cars. Simultaneously the thesis states some aerodynamic deficiencies of the cars of the period as viewed from today´s perspective.

History and Present of Formula 1 Aerodynamic Components
Olšák, Jiří ; Drápal, Lubomír (referee) ; Vančura, Jan (advisor)
This bachelor thesis deals with research themed the history and present of Formula 1 aerodynamic components. It focuses on those components, that significantly have affected the aerodynamic properties and behaviour of F1 cars, as in the past, so in the present. It also discusses the categorization of the various elements of the current F1 cars, followed by evaluation of insight into the overall aerodynamic loads.

Aerodynamic analysis of the Aircar 5.0 flying car prototype
Jánošík, Tomáš ; Jebáček, Ivo (referee) ; Popela, Robert (advisor)
This thesis focuses on CFD analysis of the Aircar 5.0 flying car prototype. The theoretical part covers basic information about the connection between the aerodynamics of airplanes and cars as well as cars themselves. The computational part begins with the calibration of the mathematical model, continues with the CFD simulations, which have the role to determine basic aerodynamic characteristics of the Aircar in vehicle mode. There are several configurations tested to find out their influence on aerodynamic stability and their advantages and disadvantages are summed up in the conclusion chapter.

Design of aerodynamic wings of Formula Student / SAE
Fryšták, Lukáš ; Lajza, Ondřej (referee) ; Popela, Robert (advisor)
The objective of this thesis is design of aerodynamic wings for Formula Student/SAE car. Firstly, Formula Student is introduced and regulations concerning aerodynamic devices are discussed. Design of two-element inverted wing is described and this two dimensional airfoil section is analyzed in CFD. Forces acting on a moving vehicle are analyzed and effect of aerodynamic loads on vehicle dynamics is considered.
