Flying drones rescue systems
Hájek, Tomáš ; Janhuba, Luboš (referee) ; Pejchar, Jan (advisor)
This paper addresses the issue of security and integration of UAVs in air traffic operations and analyses possible risks. This work defines methodology to demonstrate airworthiness of the parachute recovery system under extreme climatic conditions. The first part of the methodology deals with the compliance performance requirements in external environment and the second part verifies performance parachute canopy. Methodology developed herein is subsequently verified by practical tests on parachute recovery system Galaxy GBS 10.

Design of the propulsion unit of the competition model airplane with vertical take-off and landing
Pilát, Adam ; Navrátil, Jan (referee) ; Hájek, Tomáš (advisor)
This bachelor’s thesis was written in order to design the propulsion system for a vertical takeoff and landing competition model airplane intended to participate in the New Flying Competition 2022. The task of the thesis was to analyze the rules of the competition and design the propulsion system. The research section includes an analysis on the competition’s rules followed by a review of the propulsion system components. In the next section, a basic analysis of the parameters of the airplane is performed for the purpose of the airplane fulfilling the competition requirements. In the last part of the thesis, a propulsion system components selection method is proposed and carried out. The output of the thesis is a propulsion system suitable for use in the designed airplane.

Design of competition model fuselage
Bednář, Peter ; Löffelmann, František (referee) ; Hájek, Tomáš (advisor)
This bachelor’s thesis deals with the design of the fuselage of the competing model aircraft. The introduction describes the student team, Chicken Wings, and also explains the upcoming Air Cargo Challenge 2019. Furthermore, the search section lists the individual types of materials and carbon composite manufacturing technologies. The second part of the thesis deals with the individual phases of the aircraft design and the definition of fuselage. Moreover, the practical part of the thesis begins with a statistical overview of mass-produced models F3B and F5J categories and the subsequent design of the individual parts of the fuselage and the mass analysis of the model. The conclusion justifies the choice of individual parameters.
