Strength design of the aircraft spur
Profota, Martin ; Vosynek, Petr (referee) ; Vrbka, Jan (advisor)
This master thesis deals with computational stress-strain analysis of the tailskid of airplane L410 NG with main focus firstly the check current design of the tailskid and then the design another design solution with the able to absorb as much as possible the deformation energy. Solution of this problem is performed using computational modeling utilizing numerical simulation of quasi-static and crash deformation load of the tailskid with using explicit Finite Element Method (FEM) in program ABAQUS v6.14. After the introduction with problem situation and tailskid assembly introductory part is devoted to the research study of various designs of the tailskid for different types of airplanes. There follows these theoretical general principles of thin-walled structures and buckling of them. Before the creating of the computational model itself, the explicit form of the Finite Element Method is better described. The conclusion of this thesis deals with the mutual comparison of the most advantageous design variants of the tailskid and the selection of the most suitable one of them for the airplane L410 NG.

Radar Altimeter for Ultralight Aircraft
Zahradník, Jiří ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
In this bachelor thesis author designs a radar altimeter. In this thesis the emphasis is placed onto modular architecture and that is why this altimeter is designed as a group of independent modules communicating through BSD sockets. Software implementation is made in C++ and for sound generator is used library PulseAudio. Next topic is multithreading safety implementation of queue and stack which was made by template class to keep simplicity and generality.

Aspects of certification areas for take-off and landing
Jaša, Marek ; Chlebek, Jiří (referee) ; Hammer, Jaromír (advisor)
The Bachelor´s thesis targets to specify conditions for certification of the airport area according to requirements of L14 and LA3 regulations and subsequently to apply them to the specific area. This work determines conditions for take-offs and landings, that can be executed at any land. These conditions are contained in Act No. 49/1997 Coll., civil aviation law in Czech Republic. Next topic contained in the thesis is the most common types of airplane that could use the airport area in the future. It also determines their take-off and landing flight performance. In this context there are defined take-off and landing and conditions affecting their length. The chosen airport area is described in the main part of the thesis, primarily its situation and parameters. There are also terms under which the land could be used and certificated.

Design Study of VFR Airport
Brandejský, Petr ; Veselý, Petr (referee) ; Ptáček, Pavel (advisor)
The final master´s thesis targets to create concept study of VFR airport.This airport should be build up in southeast part of Czech republic, in the vicinity of the town Valašské Klobouky. In this work there are explained essential terms and definitions refered to basic rules and law. There are explained also civil aviation law and requirements of L14 regulations. Aeroclub is submitter of this work. It establishes basic conditions for airport area searching. The length of the runway is influenced mainly by performance of used aircrafts. It was impossible to find any acceptable field in searched area. There is a posibility how to solve this problem. There can be build up a runway for take-off and landings of small aeroplanes. In the second part of this thesis there are defined basic requirements on these fields. These requirements are applicated on chosen field. At the end of this thesis there is propounded an option how to dislocate runway, taxiways, aprons, hangars and other buildings.

The influence of meteorological conditions on take-off and landing powered aircraft
Koupý, Zdeněk ; Hammer, Jaromír (referee) ; Krška, Karel (advisor)
This thesis deals with influence of various meteorological conditions and impact phenomena on aircraft performance during take-off and landing, it means with performance of their air power units. I focused on influence of meteorological elements (not phenomena) like physical characteristics of the atmosphere including wind. The target of this thesis was to create a clear set of meteorological elements which affect the aircraft performance during these critical phases of flight including their analysis, explanation and related recommendations. Analysis of some meteorological elements also contains figures from particular world´s airports.

Alternative ways to take off and land for fixed-wing aircrafts
Cäsar, Tomáš ; Matějů, Jiří (referee) ; Zikmund, Pavel (advisor)
Target of this thesis was to propose and evaluate workability in matter of basic physical principles for shortening lengths of take-off and landing distances especially for small, single-seated aircrafts. These variants were proposed in order to be used at building roofs for transport of employees to work and back. Every variant is presented with loads, which would affect aircraft and pilot and also estimated runway length for comparison with classic landing. Calculations were made for two versions of aircrafts, one for present, achievable with current technologies and second futuristic, which takes into account expected development in aviation.

Comparison of traditional aeronautical precise approach navigation systems efficiencies with that of the LADGPS
Válek, David ; Sklenář, Filip (referee) ; Vosecký, Slavomír (advisor)
This work deals with the possibilities of using technologies and means of satellite navigation in civil air transport, focusing on the precise instrument approach of transport aircraft. The work describes traditional systems for guiding aircraft in the final phase of flight, their characteristics, principles of operation, advantages and disadvantages. Similarly, satellite navigation technology and its subsystems are described, which contribute to improving the accuracy and safety of these guidance devices. By analysing the characteristics and efficiency of all devices, a conclusion has been reached that the guidance technology could take hold in the future.

History of Civil Aviation 1970-2000
Zubrvalčík, Jan ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
The main aim of this bachelor‘s thesis is utilize consice summary of history of civil aviation between year 1970 to 2000 and compare their performance. This era is typical with out-set of airplanes with large capacity and new construction solutions. This thesis is focused on planes for long distance with large capacity, but also on planes for middle and short distances too. Thesis is divided by range of airplanes and special charter is about supersonic civil planes.
