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.

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.

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.

Individual ski lesson of preschool children
Černá, Petra ; Matošková, Petra (advisor) ; Polášková, Marcela (referee)
Title: Individual ski lesson of preschool children Targets: The target of diploma work is on base of observation the interaction of ski instructor or parent and pupil to show, which kind of ski lesson is more appropriate for preschool age. Method of diploma work: In this work I used attended observation and controlled conversation. During attended observation I have taken notices progress of ski lesson to my beforehand prepared table with fixed criterions (age of child, sort of teacher, duration of teaching lesson, length of slope, kind of terrain, teaching methods, way of snowplough practice, correction of mistakes, communication during teaching lesson). I used controlled conversation after the end of lesson and the conversation was led with parent of child and instructor. Controlled conversation was composed from open questions. During conversation I used questions regarding experience or behaviour, knowledge and perception. Result: Establishing of the first contact of a teacher and a child was performed only during instructor lesson. The instructor had to get child to his side. Between parent and child hasn't been first contact. During the lesson there was communication only between the teacher and the child. Instructor tried to communicate with child during whole lesson.
