Design of and F5F Race Model
Faltičko, Martin ; Bidlo, Michal (referee) ; Chudý, Peter (advisor)
This document aims to explore the possibilities for design optimizations of an aircraft model in a specific competition category. On the basis of simulation of the model described by the basic parameters the characteristics are evaluated. Then an appropriately chosen optimization algorithm refines the design. The evaluation takes into account several criteria including aerodynamics, stability and weight.

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.
