High-speed Condesing Steam Turbine
Klíma, Petr ; Trojan, Aleš (referee) ; Fiedler, Jan (advisor)
ith one controlled extraction and one uncontrolled extraction, calculation of the flow channel at all stage, design and calculation of the regulation valve and create connection diagram of steam turbine and air cooled condenser. At the beginning of this work is an overview of manufacturers of steam turbines and their unified products. Master thesis was developer with G-Team, a.s. as using calculations and the instructions given in the recommended literature with supporting CFD simulations to determine the loss coefficients and FEA simulations to determine the eigenfrequencies blades.

High-speed Steam Turbine
Vitovská, Michaela ; Trojan, Aleš (referee) ; Trojan, Aleš (referee) ; Fiedler, Jan (advisor)
The diploma thesis deals with the design of a high-speed steam turbine at given parameters provided by G-Team a.s. in Velka Bíteš. The introductory part briefly focuses on historical development of steam turbines, their operational principle and process of energy transformation. In the main part the machinery analysis of high-speed turbines has been carried out. In addition, a preliminary design of the number of turbine stages has been done. Furthermore, a thermodynamic calculation of flow channel for given input and output paramaters has been done together with the conception of construction design and turbogenerator layout. The final part introduces technical comparison of a one-stage and multy-stage high-speed steam turbine.

The Technical Monuments And How to Use Them in Second Primary School Education
TROJAN, Aleš
The thesis is focused on technical monuments in South Bohemia. Selected monuments are applied in lower secondary school teaching by means of excursions and projects. The theoretical part deals with the project teaching and its use in education. Subsequently the attention is paid to technical education, technological literacy and their roles in lower secondary schools. The last chapter of the theoretical part deals with technical monuments, their official status and typology. The final section is devoted to selected technical monuments and attractions, which are briefly described. Individual excursions and projects for teaching in lower secondary schools are developed in the practical part of the thesis. The information base for teachers and expansion options of individual excursions to other objects are also included in excursions and projects. The supplement of the thesis includes maps and other documents for successful realisation of excursions or projects.

Dependency analysis of efficiency of dozers on technology work and technical parameters.
TROJAN, Aleš
The paper deals with the explanation of technological works of dozers and the division of operational institutions of a dozer. The aim of this work is to propose principles for the calculation of the actual performance of dozers in relation to operations. This work can be a useful document that can be used by construction companies for accurate calculations of dozer efficiency and thereby achieve improvement and optimization in relation to other operations.
