Development and present state of Fly-By-Wire systems in aircraft controls
Cuber, Dominik ; Koštial, Rostislav (referee) ; Dubnický, Lukáš (advisor)
This bachelor thesis deals with a research on the development and state of art of Fly-By-Wire (FBW) flight control systems. In the first part, control surfaces and an overview of aircraft control systems are described. The main part addresses the Fly-By-Wire system in which the principle, control laws, advantages and basic elements of this system are described. This is followed by a depiction of the development of FBW systems, and the final section compares the Airbus and Boeing approaches to Fly-By-Wire. Overall, the thesis attempts to provide an overview of FBW systems, their development and their use in modern aviation.

History of Civil Aviation 1970-2000
Sehnálková, Radka ; Bencalík, Karol (referee) ; Chlebek, Jiří (advisor)
The main subject of this bachelor’s thesis is concise and clear history of civil aviation between year 1970 and 2000. This era is typical with outset of large transport aircraft, which are intended for long distances and big number of passengers, but attention is also paid to aircraft, which are not for transport of so many passengers. Thesis is focus on concise description of individual aircraft, divided by its types of propulsions and producer.

Cockpit instruments for four-seater sport and leisure aircraft
Liberda, Jiří ; Janhuba, Luboš (referee) ; Hlinka, Jiří (advisor)
This master thesis includes a comprehensive review of four-seater sport and leisure aircraft with focus on their cockpit instruments. The description of the selected glass cockpits is listed. Thesis also includes design of instrument panel, which is designed according to the relevant regulations and standard configuration of existing aircrafts. There is also a brief overview of the regulations necessary for the installation of these systems in the aircrafts. At the end of the this work is failure mode and effects analysis, with calculation of probability malfunction for critical functions.

Retractible landing gear design for Z 143 LSi airplane
Gregor, Jiří ; Vaněk, František (referee) ; Píštěk, Antonín (advisor)
The diploma thesis deals with the design of the replacement the Z 143 LSi landing gear with the new VUT 100 type landing gear in a retractable system. The first part of this thesis is devoted to the description of the Z 143 LSi aircraft and its landing gear and the description of the retractable landing gear type VUT 100. The next part describes the possible variants of the installation the VUT 100 landing gear, which are critically evaluated. Then there is selected the final variant for the installation, which is designed in Catia V5 software. The final design includes remotorization with Lycoming IO-390 and new design of engine bed. For the proposed solution, a new mass analysis with the calculation of centrations, new cases of ground load, a new flight envelope of load and additional cases of load of a new engine bed are prepared. The proposed engine bed is analyzed by the finite element calculation method in the MS Patran software. Finally, a possible scheme of the chassis retraction system is proposed.

Construction of ultralight aircraft control
Marek, Ondřej ; Šplíchal, Jan (referee) ; Juračka, Jaroslav (advisor)
This bachelor thesis deals with control of ultralight glider D-14. Based on the research of applied construction solutions of ultralight airplanes I designed my own solution of the specific elements and construction nodes. Also, in accordance with the UL-2 directive load of main control systems are determined. 3D model of the glider fuselage with the elements of the particular assemblies is attached.

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.

Evaluation of Ultralight Aircraft Production in the Czech Republic
Zvolánek, Jiří ; Ptáček, Pavel (referee) ; Šplíchal, Miroslav (advisor)
The final bachelor’s thesis analyses the status of Czech producers of ultralight aircrafts to foreign markets and evaluates their production. It describes the history and emergence of ultralight aviation in the Czech Republic and the emergence of the Light Aircraft Association, which administers ultralight aircrafts. The work contains the definition of light aircrafts, both for the Czech Republic and the U.S. and Europe, also includes a catalogue of ultralight aircrafts from Czech producers. There are examples of the development of the largest Czech producers of ultralight aircrafts and also they are compared to their foreign competitors on the U.S. market of Light-sport Aircraft category LSA.

Aircraft windshield blowing: solution and design possibilities
Šamša, Petr ; Fišer, Jan (referee) ; Jícha, Miroslav (advisor)
My thesis is considering with aircraft windshield blowing for airplanes designed according to CS-23 regulation. The first part introduces the size of precipitation clearing area in connection with CS-23 regulation and report SAE AIR805C. Next chapter describes a few possible design solutions which can be potentially used for windshield precipitation. There are also other methods analysed in that part. There are not only the casual systems like windshield wipers but some more rare or new technologies too. It can be some fluid repellent surfaces or blowers in that category. The third part deals with jet blast system in detail. There will be a design calculation for airflow conditions which are important for the correct function. The last quarter of this thesis mentions the experiment what should compare the theoretical computations from the third part with the real values.
