On the production of blades for steam turbines
Chromý, Marek ; Bařák, Martin (referee) ; Píška, Miroslav (advisor)
The diploma thesis is focused on solution of technology optimization of steam turbine rotor blades machining. Main goal is to evaluate machining cost accord-ing to change of tools feedrate speed and proposed production technology. During experimental production was monitored the tool wearing VBB of roughing and finishing mill cutter depending on machining time tA. Further, there was evaluated new technology time saving – two piece production and material consumption. The results of experiment are material cost saving and noticeable time reduction for machining of rotor blade, mainly reduction of non-machine working time.

Armed Forces and Identity: A Constructivist Analysis of the Role of the Czech Airforce Figters
Chromý, Marek ; Ludvík, Jan (advisor) ; Rychnovská, Dagmar (referee)
The study examines the arguments raised for or against possessing supersonic aircrafts of the Army of the Czech Republic. The aim is to identify the arguments primarily during deciding on the acquisition of new aircrafts, because the old ones were retired in 2005. In the first part, the author analyzes various approaches to purchasing and possessing weapons systems (nuclear weapons, supersonic aircrafts and tanks) and defines three approaches, which he expects in discourse and which he will examine. The main part of the study deals with analysis of the arguments for and against the acquisition of supersonic aircrafts through discourse analysis. As a frame of reference author establishes the deputies and senators of the Parliament of the Czech Republic, the professional public and official documents of the Ministry of Defense and Army of the Czech Republic. By analyzing the discourse the author concludes that the official documents of the Army of the Czech Republic looks at supersonic aircrafts as a means of national defense strictly, professional public also looks at supersonic aircrafts this way in most of times. MPs and senators argue for acquiring supersonic aircrafts not only by defense purposes, they argue that supersonic aircrafts is mandatory purchase, because loss of the supersonic...
