Konstrukční návrh bezpilotního letadla pro aplikaci v zemědělství
Frydrych, Jan
The diploma thesis deals with structural design of unmanned aircraft for application in agriculture. Thesis describes precision agriculture, agricultural machines, unmanned aircrafts, and technology of 3D printing. An analysis of these topics is performed, and it is also mentioned the legislation for using unmanned drone in the Czech Republic. In the second part the diploma thesis is focusing on structural design of unmanned aircraft and its individual parts. The structural design is extended by a draft of docking station which also works for charging the aircraft. The production technology was chosen 3D printing using PET-G material. In the end of the thesis, the process of 3D printing and mechanical testing of ASA, PET-G and rPET-G materials is described.

Analýza výstupních parametrů souprav na zpracování půdy
Němec, Lukáš
The thesis introduces and briefly describes an overview of tillage's technologies which are applied in modern agricultural operations. These are the technical resources by which it is possible to achieve maximum productivity values, with minimum impact on the environment, which are requested by their users these days. It further approaches on trends in the area of the precision agriculture and provides a list of innovations which have the potential to streamline systems of tillage and crop production. Finally, the thesis analyses the output of parameters of the kit Case IH Quadtrack and Horch Tiger Lt. This is in particular the dependence of values such a performance and hectare consumption on the operating mode of the engine. This analysis was based on data collected during field measurement on 30th March 2016 on land owned by company called Roštenice a.s.

Analýza vybraných parametrů spalovacích motorů
Němec, Lukáš
The thesis introduces and briefly describes the technologies which are applied in modern diesel engines used in agricultural industry. They are facilities with which it is possible to achieve the maximum productivity, with minimal impact on the environment, which is now required by users. It also describes future trends in engine design and offers a list of innovations, which are currently under the development and have got the potential to improve parameters of diesel engines in the future. There are also described characteristics of combustion engines, according to which are the selected parameters assessed. Last but not least, the work deals with the analysis of selected parameters of the internal combustion engine depending on their structural design. This analysis was based on data obtained from the Institute of DLG and independent testing laboratory of motor vehicles at the University of Nebraska.
