Design of single seat aiirplane by the UL - 2 regulation
Kövér, Ondřej ; Schoř, Pavel (referee) ; Píštěk, Antonín (advisor)
Bachelor´s thesis solves conceptual design of oneseater aircraft by the UL-2 regulations, that is up to 300 kilograms of take-off weight. In the first part of the thesis, there is survey of similar aircrafts and summary of their important characteristics. In further section are possible conceptions and the best choice of them outlined. Afterwards are characteristics of carrier surfaces, load calculation and flight envelope mentioned. The last part deals with calculation and design of engine mounting.

Influence of wing design modification on aircraft polar curve
Mixová, Alexandra ; Matějů, Jiří (referee) ; Navrátil, Jan (advisor)
This thesis focuses on determining the polar curve of Roko NG aircraft, its evaluation and design of possible wing modification; on the influence of said modification on the polar curve and determination of basic flight performance. The introduction explains basic concepts and problems of aerodynamics. The following part discusses the particular type in comparison with similar ultralight aircrafts. Measurement determines the actual polar curve which can be compared to the analytically determined polar curve of the existing airplane, and to the analytically determined polar curve of the plane with modified wing. From this newly defined polar curve, the basic flight performance is expressed and compared with the flight performance of the existing aircraft.

Structural design and stress analysis of ski landing gear for airplane with short take-off and landing
Hostinský, Vladimír ; Vaněk, František (referee) ; Katrňák, Tomáš (advisor)
The aim of this thesis is a design of a ski landing gear for the STOL Cruiser airplane and strength analysis of its parts with consideration of UL-2 and CS-LSA regulation requirements. First part follows the design process from a concept to detailed design. Decisions taken during the process and reasons behind them are discussed. In second part requirements of regulations for said aircraft’s landing gear are summarized and forces acting on the landing gear are calculated. This calculation is followed by a strength analysis of critical parts. Analysis of composite body of the ski carried out with a use of FEA and optimalization of its composite material layout is presented in a more detailed way.

Conceptual design of an upper wing aircraft using structures parts of the previous type
Koudelka, Jaroslav ; Katrňák, Tomáš (referee) ; Jebáček, Ivo (advisor)
The aim of this diploma thesis is to design a new high-wing aircraft for the company TL ultralight using the structural elements from another models from their portfolio. The design is created with an emphasis on crew comfort and cabin ergonomics. The first part of the thesis focuses on the description of the basic requirements for the aircraft and its classification in aviation regulations. It also contains a research part of competing types and currently produced type, which the proposed aircraft should replace in the company's portfolio. Then follows the characteristics of the individual parts of the airframe, the specification of the parts, which will be used from another types from portfolio, and parts which will be completely designed. Great emphasis is placed on the layout of the interior and its design and ergonomic. The proposed aircraft then demonstrates theoretical calculations of basic performances and a preliminary mass analysis. In the end, the benefits of the newly designed aircraft are evaluated with respect to the competing types.

Landing gears of ultralight airplanes and its loading
Talanda, Tomáš ; Jebáček, Ivo (referee) ; Juračka, Jaroslav (advisor)
This bachelor thesis deals with engineering solution and loading of ultralight aircraft landing gear. At first requirements for landing gear are mentioned, then the basic arrangement and structural design of aircraft landing gear are explicated. Next part contains calculation procedure and sample calculation of P92 ECHO aircraft landing gear loading. The last part of the thesis deals with experimental verification of landing gear loading, that was calculated before.

Design of ski landing gear for skiplane with short take-off and landing
Hostinský, Vladimír ; Dubnický, Lukáš (referee) ; Katrňák, Tomáš (advisor)
The aim of this bachelor thesis is a selection of the most suitable ski landing gear for a use on a given STOL aircraft and its installation on the aircraft according to the law regulations and requirements of the aircraft manufacturer. First part is strictly teoretical and deals with existing design variants of an aircraft skis. More practical second part of this thesis starts with a market research, which creates an overview of existing options of ski landing gears suitable for use on the aircraft. Part continous with a reduction of the options and ends with a choice of the most suitable one. Final part is devoted to the problem of an installation of the landing gear to the given aircraft with consideration of existing law regulations.

Engines for ultralight airplanes
Voltr, Martin ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor thesis deals with the collection of information about the power units for ultralight aircrafts. It deals with their design solutions, technical parameters and usability. In the next part we will find a comparison of these units according to the characteristic parameters. The work also briefly describes the history, legislation and issues of ultralight aircrafts and their propulsion units.
