Modern hybrid drive of passenger vehicles
Švoma, Jan ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This bachelor thesis deals with the current hybrid-drives in passenger cars. The thesis contains the categorization of hybrid systems according to structure and use. It also discusses the analysis of individual components and describes their suitability for use in different situations. It is focused on current offering of hybrid vehicles and development opportunities. At the end of are evaluated economic aspects and prospects for the use of these systems in the future.

Uses of two-shaft combustion turbine for cases serial and parallel arrangement
Minář, Luděk ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
Master thesis deals with analysis of characteristic points of two-shaft combustion turbine cycle for two different concepts of turbine’s arrangement. Computational model is compiled within the thesis for serial and parallel arrangement. Thermodynamic magnitudes of characteristic points of cycle are calculated with the computational model for designed operating point. Initial values of the computational model are chosen in consideration of reaching compromise between maximal thermal efficiency and maximal specific power.

Use storage thermal power in Czech republic
Bednář, František ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This diploma’s thesis analyzes the possibility of accumulation of thermal power plants in the Czech Republic. The thesis is divided into several parts. The first part describes the different types of storage power plants, the historical development of power storage for compressed air and the appropriateness of their location. The second part is devoted to the design of storage power plant for compressed air in South Moravia. In the next chapter, a calculation is made of all equipment storage power plant, including turbo-compressor, combustion chamber, combustion turbines, the volume of storage tanks and two heat exchangers. The last part is the economic analysis of the return on investment of such a project.

Design of low-emission combustion chamber
Trnka, Jakub ; Veselý, Stanislav (referee) ; Fiedler, Jan (advisor)
This diploma thesis deals with design of low-emission combustion chamber, which burns natural gas. The type of the combustion chamber is CAN with six combustion chambers with parallel flow and mixer. A swirler is used like stabilizer. The first part of the thesis describes combustion chambers. Next part is about calculation of circuit of combustion turbine, where combustion chamber is, distribution of air flow and design of main dimensions of combustion chamber. Technical documentation and tables of coefficients are in the attachment.

Increased power microturbines operating in indirect circulation
Polák, Luboš ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Turbogenerator unit 100B TGU, produced in the First Brno Engineering Velká Bíteš a.s., works in Brayton indirect circulation. The aim of this work is the proposal to increase performance levels of technological unit in which the micro-turbine is applied. The work presents various ways to increase performance and efficiency of circulation. The possible options are compared with each of the technological and economic terms. Based on these criteria was selected variant feeding additional water into the circulation. For this design was the work of a mathematical model based on, which was established as the economic balance of the selected variants. The thesis also proposes a technological scheme, which is already incorporated the selected variant and an outline of the verification tests.

Turbine drive for charger unit of bus
Obrlík, Jan ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Diploma thesis deals with use of combustion chamber to drive the electric bus charging unit. Based on the research and analysis of operation economy, a turboexpander with an air pressure tank is selected to drive the charging unit. A thermodynamic design is created for this variant. Based on this design a unit layout is proposed. Layout drawings are created for the proposed layout.
