Design of composite aeroplane wing-fuselage joint
Sadovský, Hynek ; Šplíchal, Jan (referee) ; Juračka, Jaroslav (advisor)
This master's thesis deals with design, strength calculation and technological solution of wing-fuselage joint for composite four-seater aeroplane certificated by CS-23. Design is focused on optimal space utilization, low weight and simple manufacturing and assembly. Main output is technical documentation consisting of drawings and technological lay-ups. Conceptual design was chosen after analysis and weight estimation. With strenght calculation for composite materials it was possible to design composition of primary parts and also specify manufacture processes. Assigment was solved by unusuall conceptual design, which claims higher precision manufacturing, but it saves weight.

Steam ejector pump
Třináctý, Jan ; Baláš, Marek (referee) ; Šnajdárek, Ladislav (advisor)
The aim of this theses is to do search about maintaining vaccum in surface condensors and subsequently propose basic dimension of one stage steam ejector. The first part deals with the issue of vacuum. The following part is dedicated to description of various types of vacuum pumps. Hence it describes the principle of operation of each pump as well as their output. The following part deals with vacuum and vacuum technology in the field of power engineering. This part is dedicated to those types of vacuum pumps that are used in power engineering, especially to steam ejectors which are most widely used. The final part is addressed to the design of single stage steam ejector. This part contains the calculation of pump dimension. The conclusion evaluates the design of one stage steam ejector.

Adaptation of the UHV SEM system for growth and characterization of nanostructures
Skladaný, Roman ; Mach, Jindřich (referee) ; Páleníček, Michal (advisor)
This bachelor thesis presents mechanical design of an objective protection of ultrahigh vacuum scanning electron microscope (UHV SEM), which is a part of a complex modular UHV system used for growth, observation and characterisation of nanostructures. Main physical and technical working principles of the UHV SEM system are explained. Furthermore, adaptation of a Knudsen cell used for growth of ultrathin layers in the UHV SEM system is described. Finally, a mechanical design of a shutter reducing overheating and contamination of objective during in situ growth and observation of nanostructures is drafted. The objective shutter also protects the sample from ambient heat radiation in case that sample is cooled to cryogenic temperatures.
