Pump design
Šmíd, Pavel ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
The aim of this labour is to analyze the structural design of pumps used in the present time. First, we focus on the distribution of pumps by type of energy conversion, and there are hydrostatic and hydrodynamic. Will further comparison of these types, and enter the region of their optimal application under specific speed. This labour will focus only on the hydrostatic pumps when we will do an analysis of design performance of the individual pumps and we'll give the advantages and disadvantages of the specific pumps. We shouldn´t forget the basic technical parameters and individual areas of practical use these given types. At the end of the labour will be processed the basic equations and the ideal characteristics of pumps.

Development of rocket engines
Marcinko, Peter ; Cejpek, Jakub (referee) ; Koštial, Rostislav (advisor)
This thesis describes the development of rocket engines since the beginning to present time. The thesis is divided into three parts. The first describes the main physical principles, which have to be respected during the flight. The second part talks about the basic division of rocket engines and the used fuel types. Tle last chapter deals with Russian, American and European rocket program. It describes the main types of space rockets together with the engines they used.

Durability testing of replaceable inserts in cylindrical turning of carbon steel
Smolík, Martin ; Vítek, Jiří (referee) ; Sedlák, Josef (advisor)
The thesis deals with the problems in the field of durability testing of replaceable inserts for longitudinal steel turning. The main objective of the thesis is the analysis of the cutting process based on the results of the performed cutting tests. The cutting tests will be carried out comparatively by testing pairs of inserts, compared to each other. Wear observation is carried out by optical method using a workshop microscope and special software designed to process the acquired images. The output of the work will be an illustration of the different behaviour of the standard and the upgraded set of cutting inserts under different configurations of cutting conditions. The work provides a comprehensive view of the cutting tool testing process and quantifies the degree of influence of the various factors entering into the cutting edge wear process.

Safety assessment of NHX5500 DMG MORI machining center
Novotný, Petr ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma thesis deals with legislative purposes for the operation of machinery in the Czech Republic and the European Union. It deals with the analysis of technical standards of machinery, specific machining centers. The analysis of the risky machining center NHX 5500 DMG Mori is based on this. The result of the work is the minimization of ongoing risks and meeting the legal requirements of the state of the operated machining center.
