The mathematical model of the operating mechanism for turbochargers
Jakubec, Ján ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
The Diploma Thesis is focused to create the mathematical model of operating kinematic model for turbocharger DAVNT (Double Axle Variable Nozzle Turbine) for setting the position of vanes. The work contains a brief overview of supercharge and types of turbochargers. The main part contains a mathematical model which examines the behavior of the mechanism with considering of wear among the parts. It also includes assessment of changing in various parts of the nodes caused by mechanism wear and their influence on the mechanism due to important parameters which characterizes the mechanism. The evaluation is completed by optimizing the parameters. The final section contains the static calculation of internal forces and assessment of actuator position relative to mechanism load.

Determination of Characteristics Fan
Vymětalík, Zbyněk ; Škorpík, Jiří (referee) ; Kracík, Petr (advisor)
The topic of this bachelor thesis are fans. The first part deals with subsumption of these machines. The second chapter is devoted to their dividing. As the measured fan is radial, the third chapter presents the theory of designing this particular type. The last pages focus on finding the characteristic curves and the main dimensions. At the end, there are the sizes drafted in the way to correspond with the recommended values.

High temperature coatings for gas turbine blades
Chýlek, Radomír ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
The purpose of this bachelor thesis is the overview of technology of high temperature coatings for gas turbine blades. The familiarization with properties of individual coatings, their capabilities to increase the blades durability and their resistance to damage and temperature influences are emphasized in this work. The potential of significant increase of gas turbines efficiency using different types of coating and cooling of the blades was evaluated in this thesis. Additionally the individual coating techniques are described and compared. Last but not least, this thesis contains closer description of the state-of-the-art thermal barrier coatings including the characteristics required for the following computing part. The computing part deals with calculation of heat transfer through the blade. The conclusion is dedicated to the future use of the coatings from the author's perspective.
