Design of turbine engine inlet in NACA-duct configuration
Babinec, Viktor ; Navrátil, Jan (referee) ; Doupník, Petr (advisor)
This master thesis is focused on design and aerodynamic analysis of subsonic turbine engine inlet in NACA duct configuration for unmanned aircraft. The first part of this paper is methodics for design considerations for NACA duct, which is based on theoretical analysis of this type of inlet. The acquired knowledge is used to design an inlet for the specified unmanned aircraft that is subject of CFD analysis. The impact of deflectors is considered in the evaluation and the solution is compared to the S-duct inlet. The proposed inlet with deflectors meets DC60 distortion criterion for all specified cases and the pressure losses requirements are met for lower velocities. Based on the results, the recommended application is for aircraft that flies in optimal design conditions for most of the mission.

Design of focusing and deflection system of electron welder
Franc, Viktor ; Sháněl, Ondřej (referee) ; Zlámal, Jakub (advisor)
Main parts of the electron beam welder are the source of electrons, accelerator, magnetic lens with deflection coils and stigmator, welding chamber with manipulation stage for welding object and vacuum system. This master thesis starts the design of the electron beam welder prototype. More precisely it is aimed not only on electron optic design, but also on construction of magnetic lens, deflection coils, stigmator, welding chamber and vacuum system.
