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.

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.

Development of materials used for downhill skis production
Václavík, Martin ; Jech, David (referee) ; Pavloušková, Zina (advisor)
The submitted thesis is a retrieval type and is concerned with the technologies and materials used in the manufacture of downhill skis with a deeper focus on the last ten years. Examined are materials for the manufacture of ski cores as well as other parts of the ski, and that in terms of comparison of the construction materials and technologies. Listed are basic elements and characteristics of skis, methods of manufacture, materials for the manufacture of individual parts of the skis and, last but not least, the types of skis. The work is eked out with the analysis of several samples of skis, on which were made cuts, they were observed and structures were compared. The aim of this observation was to determine whether the materials found in the practical section corresponds to the information contained in the theoretical part.

Design of Automatic Ski Servis Machine
Jun, Michal ; John, David (referee) ; Rubínová, Dana (advisor)
The topic of this thesis is the design of an automated machine for repairing skis and snowboards. The main objectives are to conceptually change the way in which ski and snowboard skis and edges are repaired and thus make the whole machine noticeably smaller. Another equally important goal is to address the machine in terms of ergonomics, design and the technology used. A number of concepts were drawn up, from which the final version was selected. This variant was also designed in detail. For the selected variant, a new way of attaching the ski or snowboard was designed, as well as a system for fixing and moving the machine modules. The designed machine is suitable for smaller ski centres and ski areas and acts as a machine for a complete edge and slide repair, but also as an object that can be used to present the ski area or ski centre.

Finding the technique of descending and turning the public in the Czech Republic
HRŮŠA, Albert
This bachelor's thesis was supposed to be focused on finding out the applied techniques of descending and turning the public in the Czech mountains. The method of observation using a recording device was to be used for the research. During the observation, a short video recording of each of the skiers was to be made. With the help of the obtained materials, not only the representation of individual techniques would be evaluated, but also the correctness of their implementation. The next point was to compare the information obtained with the diploma thesis of Jan Nohava from 2006, which would lead to finding out what changes and what dynamics of development skiing has taken over the last fourteen years. Unfortunately, due to the global coronavirus crisis and established government measures, it was not possible to conduct research. As an alternative solution, a detailed analysis of individual techniques of downhill skiing and conditions in selected ski resorts and the shooting of sample videos of individual techniques were chosen, which were to be included in the original evaluation.

Downhill skiing of preschool and younger school age children and its possibilities in the region of Ústí nad Labem, Teplice
Herzina, Tomáš ; Mojžíš, Otakar (advisor) ; Jahodová, Gabriela (referee)
TITLE: Downhill skiing of preschool and younger school age children and its possibilities in the region of UL and Teplice. AUTHOR: Tomáš Herzina DEPARTMENT: Institute professional development in education SUPERVISOR: PaedDr. Otakar Mojžíš ABSTRACT: Aim: The aim of this dissertation was to find possibilities of downhill skiing of preschoool and younger school age children in the region of UL and Teplice. The suitability of skiing resorts for skiing children and their teaching skiing. The comparison of ski school in the region and their ways of teaching. The another aim was to prepare the model of ski training for children and its application in teaching skiing in children and verrification of its effectiveness. Methods: The research is based on the interview (semi-structured), observation (hidden, open, participating) and data collection from the literature and the internet. Obtained data from the literature and the internet served as basis used to create questiones for an interview with skischool instructors. Results: We found that ski resorts in the region could be recomended for children and for families with small kids and for teaching skiing . In every mentioned ski resort there is at least one school of skiing Due to observation and interwiev with representatives of ski schools we found the diference...
