Stability and controllability of the Z-143 airplane with a more powerful engine
Kochtík, Martin ; Matějů, Jiří (referee) ; Daněk, Vladimír (advisor)
The thesis deals with the calculation and evaluation of the flight characteristics of the aeroplane Z 143 with the power unit Lycoming AEIO-580-B1A. The first part of the text focuses on a general description of the aircraft, its geometric characteristics and calculation of mass and aerodynamic characteristics. In terms of flight performance there are compared the values for contemporary model and developmental aircraft with a more powerful engine. Another part of the work deals with the calculation of properties in terms of stability and manageability. In this section regards the determination of the results of the flight characteristics and their assessment of whether they comply. In the end I discuss the individual results and comment the possible recommendations on correction or improvement of these properties.

The effect of paraglider`s wear and tear of different performance levels on the flight quality
Bartoš, Libor ; Dvorský, Jaroslav (advisor) ; Fiala, Miloš (referee)
Title: The effect of paraglider's wear and tear of different performance levels on the flight quality Aims: The main aim of this thesis is to define all main aspects participating in paraglider's wear and tear and changes of flight quality connected with it. Confirmation or non-confirmation of our assumption that paragliders of lower performance levels are wearing and tearing faster than paragliders of higher performance levels, especially because of poor handling by inexperienced pilots is also an important aim of this thesis. Methods: A porosimeter JDC MK1 was used as the main diagnostic tool. We have measured a porosity of skytex, material from which the paragliders are sewn. The total number of paragliders has been 253. Results were presented by using Excel spreadsheet and analyzed by using Pearson correlation coefficient. Results: Paraglider's unequal wear and tear of different performance levels was found. There has been a downward trend in wear and tear on the age of gliders from the category EN B to EN D. Performance category EN A has not been wear and tear on the level that we have expected. Keywords: paragliding, paraglider, skytex, flight quality, porosity

Rakovnik roller
Hejlová, Barbora ; Ledvinka, Zdeněk (advisor) ; Zita, Lukáš (referee)
The scope of this bachelors dissertation is breeding of Rakovnik roller, which is one of the oldest Czech breed of pigeons.
The first part of dissertation is focused at zoological classification of Rakovnik roller. There is not known much information about its origin. Generally rollers are originated from Asia.
The second part of dissertation is focused at breeding of Rakovnik roller. It contains description of chamber dovecote and its equipment. There is further described necessary nutrition and fly attributes, so called rolling. The roller can be distinguished from the other species by the rolling. This attribute is most important during the breeding. The rolling are roll overs in air during the flight of 360 degrees. In nutrition part is further described appropriate kinds of grains suitable for rollers.
The third part is focused at issues of reproduction and breeding. In this part there is described how to suitable compile a couple and how to breed squabs. Furthermore there is in detail described a look of colour layouts and patterns. The last part is dedicated to veterinary issues.
Rakovnik roller is not difficult specie for breeding or nutrition. It is suitable for starting breeders.
