Aircraft Piston Engines
Nepraš, Ondřej ; Svída, David (referee) ; Dundálek, Radim (advisor)
This thesis is focused on the overview of aircraft piston engines. Attention is devoted to known, nontraditional or other interesting construction types of aircraft piston engines largely from period of Second World War. This paper looks at the historical development of aircraft engines and propellers, and is followed by a detailed description of the piston engine design. The detailed description will form the main focus of the thesis. This will cover the main requirements and differences of aircraft piston engines types. Particular engines were selected, described and technical data was given.

Motor-driven roller conveyor
Seďa, Marek ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
Baccalaureate work deal with conceptual proposal powered motor-driven roller conveyor longitude 15 m, that the will transport cast given to proportions for either seats overleaf. Work is bent on calculation principal dimensions, solidity verification and generally general proposal constructional solving conveyor. Is free time type roller for transport casts saved on pallets, drive track, which will elect electric motor with gear - box. Last but not least also chain gearthat the to us will serve as driving element rollers. Baccalaureate work would had contribute by firms, companies and subjects, that the derive benefit from roller conveyor for transportation materials. She should enrich constructional possibilities solving these arrangements.

Legislature of the waste disposal and utilization of biodegradable materials
Pešl, Milan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this work is to give information about the issue of legislation of disposal and reuse of biodegradable waste. Legislation in the field of bio-waste in the Czech Republic and the EU is grouped into various laws and guidelines which describe particular conditions of the dumping of wastes, their subsequent processing and reuse. In this work, the definition of BDW, its composition and the current state of dealing with this type of waste in the EU and the Czech Republic is mentioned. Different methods of processing biodegradable waste, which include incineration, composting and anaerobic digestion, their advantages and disadvantages are described in this work. There are also introduced examples of BDW in the EU and the Czech Republic there.

Study of Stirling cycle
Pospíšil, Jaromír ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The purpose of my thesis is to introduce the Stirling cycle as a thermodynamic cycle and introduce theoretical analysis due to Gustav Schmidt. First part concentrates on principle of Stirling cycle and on the differences between the ideal and real cycle. Next part introduces step by step a derivation of theoretical analysis of the operation of Stirling engines due to Gustav Schmidt Last part graphically investigates the dependence of principal design parameters of Schmidt analysis on power parameter of Stirling engine.

Biogas as a fuel for cogeneration unit
Domanský, David ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The objective of this bachelor thesis is a description of biogas as a fuel for cogeneration unit. The exordium is focused on biogas origin, use and storage. The document body deals with principle of cogeneration technology and derived trigeneration technology. In the next part are described the compounds in biogas, which adversely affect the running of cogeneration units. There is also included concrete example of using the cogeneration unit with biogas.

Ideal cycles of internal combustion engines
Marušák, Ondřej ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
The thesis set out the basic thermodynamic circulation and their properties. For these orbits are shown ideal cycles gas engine and diesel engine, in which investigating thermal efficiency depending on the change in their characteristic parameters. The results are reported in tables and diagrams. For each of the engines is also a table with most values the compression ratio, the final compression pressure, the final compression temperature and maximum combustion pressure. Finally, we compare the thermal efficiency of the two orbits in the T-s diagrams.

Fluid couplings and torque convertors
Dančák, Zdeněk ; Sloupenský, Zdeněk (referee) ; Klas, Roman (advisor)
This work presents basic points and informations as to fluid couplings, torque convertors and the means of connection in hydromechanical transmissions. Work describes various structural design, it’s perfection, disavantages, and cooperation with engine. There are described the possible means of torque characteristics optimalization according to the needs of operation as well as the means to achieve better efficiency.

Search in the area of boiler and their design
Táfl, Josef ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The aim of thesis is to create a division of boilers used in industry, especially boilers to generate heat and electricity, and describe the main parts of the boiler compiles in detail. Another task of this work is to build the basic procedure for a draft industrial boilers according to valid standards. These boilers are used for strength calculation, where the calculated pressure-resistant components and thermal calculation, in which are heat areas projectet.

Hertzian contact apparatus
Marek, Jakub ; Křupka, Ivan (referee) ; Hartl, Martin (advisor)
This bachelor thesis deals with project and implementation of construction of the Hertzian contact apparatus based on commercial devices. This device will serve as education facility of Contact mechanics. Theoretical minimum needed for analytic calculation of contact between a rigid sphere and flat surface is mentioned in this thesis. Technical documentation is included.
