Launching and Operating Issues of Supersonic Business Jet
Kincová, Daniela ; Veselý, Petr (referee) ; Šošovička, Róbert (advisor)
Tato práce se zabývá problematikou zavedení a provozu nadzvukových business jetů. V dnešní době se v civilní letecké přepravě, po ukončení provozu Concordu, žádná nadzvuková letadla nevyskytují. V dnešní době existuje mnoho projektů a organizací, které se zabývají znovuzavedením nadzvukových letounů do civilního letectví a soustředí se převážně na business jety. Hlavní otázkou je, zda je vůbec vhodné, či rozumné se k tomu typu dopravy znovu vracet. Existuje hodně problémů, které toto komplikují. Tyto letouny způsobují příliš velký hluk, mají obrovskou spotřebu paliva a musí řešit nadměrné emise, létají ve vysokých výškách ve kterých může docházet k problémům s přetlakováním kabiny, navigací, radioaktivním zářením apod. Navíc zákaz supersonických letů nad pevninou letové cesty omezuje a prodlužuje. Současně vznikající projekty navíc nedosahují tak velkého doletu jako klasické moderní bussjety, což způsobuje, že se nadzvukové business jety se na delších tratích stávají neefektivní. I přes tyto problémy, je víceméně jisté, že k zavedení nadzvukových business jetů dojde během následujících 10 - 15 let, i kdyby to měla být jen otázka jisté prestiže velmi bohatých lidí.

Analysis transport system in primary agricultural production
Raška, Michal ; Kubín, Karel (referee) ; Kašpárek, Jaroslav (advisor)
This thesis presents a comparison of fuel consumption and transportation efficiency of various transport vehicles in primary agricultural production. The first part deals with the possibility of transport of materials in agriculture. The following is a description of the compared vehicles. Finally, it describes the methodology of calculation of fuel consumption vehicles, which are then compared.

Aero Engines for Aircraft up to 2000 kg
Loutocký, Jiří ; Šplíchal, Miroslav (referee) ; Juračka, Jaroslav (advisor)
This bachelor project was created like database of certified aircraft engines for aircraft with 450 - 2000 kg of weight. It is divide into four parts. Each part contains another conception of comparison. First part comprises of list of worldwide successful manufacturers and their products. Second part ranks engines by type of fuel transfer to combustion chamber and charge pressure. Third part compares engines with similar power in tables and in graphs. (Class 100, 200 and 300 horse power). Last part solves selection of most optimal engine in classes 100, 200 and 300 horse power.

Methods of reducing the consumption of modern vehicles
Kubeš, Filip ; Pech, Ondřej (referee) ; Štětina, Josef (advisor)
This thesis summarizes the basic knowledge of thermodynamics of internal combustion engines. Emphasis was put on engine efficiency and engine cycles, described by theoretical and indicator diagrams. It also introduces classification of engine efficiencies, and their respective definitions. The next section focuses on some systems used in modern vehicles, that improves engine efficiency and reduces fuel consumption. Moreover it includes conceptual solutions, that are in preparation for mass production. The last part of this thesis concentrates on economical driving techniques, and reduction of driving resistance. In conclusion, the thesis shows the direction of next development of automobiles.

iOS Application for Driving Data Extraction and Analysis via OBD-II
Pihrt, Patrik ; Beran, Vítězslav (referee) ; Bobák, Petr (advisor)
This project aims to create a mobile application for iOS devices that provide valuable information about user's car rides. Needed data are obtained by ELM327 located in OBD-II scanner which can communicate with the car. Obtained data are analyzed using table of limits. The application informs riders about their driving mistakes and giving them tips how to fix them. Trips can be saved and exported in the form of logbook. In addition application includes diagnostic functions that can be found in every other diagnostic application.

Mathematical Modelling of Vehicle Fuel Consumption
Dražka, Jan ; Novotný, Jan (referee) ; Popela, Pavel (advisor)
This bachelor’s thesis deals with a model building of vehlicle’s model based on real data and with a modelling of it’s movement and it’s fuel consumption. The thesis includes a preparation of input data as well as model building. The main aim of the thesis is the comparison among selected driving modes from the point of fuel consumption and it’s optimization. This comparison is simulated in MATLAB environement and GAMS with the use of selected optimization algorithms.
