Design of hydrogen pressure tank installation on the VUT 001 Marabu wing
Koštial, Rostislav ; Juračka, Jaroslav (referee) ; Píštěk, Antonín (advisor)
The content of this Master thesis to design installation of hydrogen pressure tanks for airplane VUT RAY 051. Survey was conducted of the available fuel cell on the market. Position of the tank was chosen over the wing using components for mounting a jet engine TJ100 M for aircraft VUT 001 MARABU. For fuel tanks were designed fairings. Further was calculated mass and centre of gravity analysis of aircraft, basic flight performance of aircraft and the drag variation in the location of the tanks above the wing. Further the strain and strength of hinges was calculated.

Human powered airplanes overview
Valuch, Tomáš ; Koštial, Rostislav (referee) ; Zikmund, Pavel (advisor)
In this bachelor thesis is elaborated historical development of human-powered aircrafts. The aim is to asses an overview of human-powered aircraft, to evaluate trends in the airframe structure and evaluate trends of specific design parameters. The first part deals with the historical development of the aircrafts. The next part focuses on the description of Kremer‘s prices and their importance for the development of this aircraft category. The following describes the structural components of the airframe and structural parameters. These parameters and flight performance are assessed. The last section is devoted to future developments and accomplishments records.

Fatigue Evaluation of Aircraft Structure According to FAR Part 23 Airworthiness Standards
Čermák, Jakub ; Koštial, Rostislav (referee) ; Augustin, Petr (advisor)
This bachelor thesis deals with acceptable means of showing compliance with the FAR 23 regulation based on safe-life experimental and analytical evaluation. In the introduction the author focuses on the historical development of the regulation and follows with summarization of current requirements. The subsequent pages describes in detail the certification based on full-scale testing, component testing and structural analysis using the cumulative rule. Appendix includes examples of load spectra approved by the FAA.

Analysis of aviation accidents caused by incorrect maintenance
Ježek, Martin ; Weis, Martin (referee) ; Koštial, Rostislav (advisor)
This bachelor´s thesis covers the aviation accidents caused by incorrect maintenance. It is especially dedicated to the most common human errors and conditions, that can act as precursors to incidents and accidents. The thesis consists of three parts. The first part summarizes the basic statistics of accidents. The next part analyzes the most common causes of accidents due to bad maintenance and methods, that could be used to reduce them. In the last part, there are selected accidents caused by incorrect maintenance focusing on the reformation leading to safer flights.
