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.

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.

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.

Digitalization of ultra-light plane fuselage for production of accurate mould
Véle, Filip ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
This work describes digitalization and creation of ultralight aircraft 3D model in order to create accurate moulds for fuselage lamination. Right choice of technology is based on background research. Designed procedures are described in detail as well as used equipment, hardware and software. Objective of this project is application of available methods of digitalization to create 3D aircraft model and its usage for accurate mould design.

Design of airframe mold for ultra-light aircraft manufacturing
Zatočilová, Aneta ; Dočkal, Aleš (referee) ; Paloušek, David (advisor)
This diploma thesis deals with digital data processing during the design of a mould of ultralight airplane airframe. The final digital model meets the demands on manufacturability by using CNC machining. The realization, in compliance with the reverse engineering approach, was conceived in four phases, which had to be solved step by step in order to preserve the continuity of the process. The phases correspond to the main chapters of the practical part of the thesis. The first part is focused on 3D digitalization of airplane fuselage by using an optic scanner ATOS and photogrammetric system Tritop. The result of this part is digital data of fuselage geometry in form of polygon grid. Next part deals with software reconstruction of collected data – by optimizing polygon grid in order to provide suitable base for surface modeling. The third part, the most time demanding, handles the creation of airplane fuselage surface model. Geometry has to satisfy requirements for smoothness and tangential or curvative connection of surfaces, including other requirements resulting from model usage. The final part of the thesis documents the procedure of deriving a mould from the aircraft fuselage geometry.
