Conceptual design of air- mobil
Podhorský, Matěj ; Zikmund, Pavel (referee) ; Píštěk, Antonín (advisor)
The topic of the thesis is a conceptual design of a roadable aircraft. The comparison of existing concepts is made, as well as description of proposed solution, aircraft mass analysis, basic aerostatic calculations, flight and gust envelope calculation and a design of truss construction of the fuselage. The CS-VLA, alternatively ELSA-K, has been used as a certification base. The compliance to this certification specification is one of the goals of this thesis.

Flight performance of competition RC airplane
Majtán-Černák, Tomáš ; Zikmund, Pavel (referee) ; Hájek, Tomáš (advisor)
This Bachelor thesis is dealing with designing procedures for measuring flight performances of aircraft model, built according to Air Cargo Challenge 2015 competition regulations. Firstly, the competition is introduced, together with its requirements and regulations. Then, aircraft with its basic design parameters is presented. As a basis for designing flight test, thesis includes introduction of theory on this matter. Finally, Bachelor thesis contains measurement methodology itself as well as evaluation of the results.

Wing leading edge active flow concept analysis
Mahdal, Vít ; Zikmund, Pavel (referee) ; Popela, Robert (advisor)
This research is focused on substitution of commonly used High-Lift devices by active flow control on the wing leading edge. The analysis is done by CFD tools with use of Reynolds-Averaged Navier-Stokes (RANS) method. In the beginning of the research, commonly used High-Lift devices are described. Solver setting and its explanation together with verification and validation is described in the following chapters. An active flow control concept is testing at the LS(1)-0413 airfoil, for 5 different positions of slots, two different slots widths (h/c= 0,0025 and 0,005) and two different blowing velocities (v_Jv_=2,22 and 4,44). In the end of this paper, physical phenomena of blowing is described together with evaluation of different cases. The best case is compared with Fowler and slotted flap at Reynolds number 2,2 million.

Space mission design
Koziel, David ; Navrátil, Jan (referee) ; Zikmund, Pavel (advisor)
In this work, there are basic laws and knowledge relating to space flights into an orbit around the Earth. Also, there are instructions for beginners, who want to work with the GMAT program (General Mission Analysis Tool), which is the program used for designing space missions. In the final part of the work, there is also a use of the program demonstrated on a specific mission of a satellite (CubeSat) into the Geostationary Earth Orbit. In this section, there is a described method of work, individual relevant functions of the program and possibilities, and a way of work in it. Finally, graphical and data outputs of the simulation are evaluated. Therefore, the output of the work is complex characteristics of the basics of problems of space mission design and a brief GMAT software guide, which could be used in the future to teach.

Aerodynamic design of transonic UAV glider
Kóňa, Marián ; Pejchar, Jan (referee) ; Zikmund, Pavel (advisor)
This master thesis is focused on aerodynamic design of transonic glider, which is assigned for following an airliner at cruising regime of flight. Main goal of the thesis is to determine basic geometrical design of airplane with respect to Whitcomb aera rule, mass analysis and drag polar. Weight analysis includes determining center of gravity according to longitudinal static stability margin. The drag polar of the airplane is determine for cruising regime of flight, that means the regime of following an airliner.

Assistant systems in car and aircraft control
Novotný, Timotej ; Horpatzká, Michaela (referee) ; Zikmund, Pavel (advisor)
The bachelor thesis deals with assistance systems in cars and aircraft. The aviation sector is focused on GA aircraft. This thesis describes assistance systems used in cars and aircraft, their contribution to traffic safety and limitations of these systems. The comparison of assisting systems in the automotive and aviation industries shows the difference in the speed of development in individual areas, which is caused mainly due to strict requirements for safety and reliability of aviation systems. Furthermore, we can see the difference in implementation of systems monitoring the condition of a driver/pilot. Although the work of a pilot is more demanding than the work of a driver, today’s aircraft do not have a system for monitoring the condition of a pilot or an emergency landing system. Part of the thesis concerning future assistance systems in aviation is devoted to the system monitoring the pilot’s condition and the automatic landing system. Both systems are still under development. However, experiments have shown that these systems could be implemented in future aircraft and increase aviation safety. The last part of the thesis mentions the future of assistance systems, which create a path to autonomous vehicles.
