Design of the open wind tunnel measuring section
Behúl, Michal ; Grim, Robert (referee) ; Hájek, Tomáš (advisor)
This thesis deals with the design and optimization of the test section of an aerodynamic tunnel, focusing on achieving ideal flow conditions. The aim of the thesis is to design an open-jet section for the current setup of the aerodynamic tunnel at the Institute of Aerospace Engineering. The introduction of the work is dedicated to familiarizing with aerodynamic tunnels. The main part of this work is the design of the open-jet section, which involves the design of the nozzle and the collector. Subsequently, it includes verifying the functionality of the design through calculations and CFD simulations.

Propulsion unit of competition model airplane
Vančo, Miroslav ; Matějů, Jiří (referee) ; Hájek, Tomáš (advisor)
This bachelor´s thesis deals with the design and validation of the operation of the model propulsion system, according to the Aero Design East rules. The introduction is focused on rules and regulations of the competition and then, the point analysis is carried out. The research section is devoted to an overview of the propulsion system components and their basic parameters. The most appropriate configurations of the propulsion system are selected, based on calculations from the manufacturer´s datasheet. These configurations are then validated by measurements of static thrust and measurements in aerodynamic tunnel. In these measurements, the responses of the limiter for boundary power are also examined. In the last part, the choice of the propulsion system is completed.

Wing system design of competition aircraft
Mahdal, Vít ; Hájek, Tomáš (referee) ; Katrňák, Tomáš (advisor)
This bachelor’s thesis deals with the wing system design of competition aircraft. The thesis consists of five main parts. The first part is an introduction to the competition – Air Cargo Challenge, and the mission of UAV. The second part details the compilation of flight envelope and loads acting on the aircraft. Part three describes stress analysis of the old fabric method of wing construction. Part four of the thesis gives suggestions of a new wing system design, and its stress analysis. The final part of this bachelor’s thesis describes the advantages and disadvantages of the new system design, and compares them to the old version.
