Návrh zástavby vodíkové tlakové nádrže na křídlo letounu VUT 001 Marabu / Design of hydrogen pressure tank installation on the VUT 001 Marabu wing

Koštial, Rostislav January 2010 (has links)
The content of this Master thesis to design installation of hydrogen pressure tanks for airplane VUT RAY 051. Survey was conducted of the available fuel cell on the market. Position of the tank was chosen over the wing using components for mounting a jet engine TJ100 M for aircraft VUT 001 MARABU. For fuel tanks were designed fairings. Further was calculated mass and centre of gravity analysis of aircraft, basic flight performance of aircraft and the drag variation in the location of the tanks above the wing. Further the strain and strength of hinges was calculated.

Aerodynamická analýza a návh úprav přechodu křídlo-trup letounu L 410 NG / Aerodynamic analysis and design modifications of L 410 NG aircraft wing-fuselage junction

Derevjanik, Šimon January 2013 (has links)
This thesis deals with CFD analysis of a wing-fuselage junction on L410NG airplane. Possible modifications are proposed as well. Calibration problem solved in the introduction serves as a pathway for validation of the results and gives insight into the CFD methodology. The main part analyses the airplane's flow field and shows the details of the modelling process. Description of the computing network followed by final evaluation is presented. Next part is devoted to the creation and aerodynamic analysis of the modified geometry. Final part of the work compares both basic and modified geometry.

Analýza vývoje vegetačního krytu a využití země v povodích toků Novohradských hor (povodí Malše po soutok s Tichou, Tiché, Pohorského potoka po soutok Černou) / Analysis of land use and land cover development in the catchment areas of the water streams in the Novohradské Mountains (catchment areas of the Malše up to the confluence with the Tichá, of the Tichá and the Pohořský brook up to the confluence with the Černá)

JIRÁSEK, Petr January 2010 (has links)
The Dissertation submitted describes and analyses the development and existing situation of the landscape (in terms of land use and land & vegetation cover) in the {\clqq}Novohradské Mountains`` region between 1955 and 2009, in the cadastral district situated in the catchment areas of the Malše river, as well as of the Tichá river and of the Pohořský brook. On the basis of the statistical data of the Land Registry and detailed terrain mapping there have been analysed individual types of land and distribution of elements of the land cover in relation to individual cadastral districts. The results of the issues examined are contained in the Annexes to this Dissertation (tables, charts and figures) and are completed with verbal descriptions in the text part of Dissertation.

Ověření vlivu složení betonů na životnost cementobetonových krytů / Verification of the composition of the concrete durability of cement-concrete covers

Černá, Eva January 2018 (has links)
Alcali – silica reaction often causes destruction of a concrete.constructions. In the theoretical part is described creation and causes of the ASR including assessment of individual components of concrete and their testing. The practical part is devoted to the results of some control tests of the concrete cover in the section 18 of the highway D1 (Měřín - Velké Meziříčí) and section D1-20 (Velké Meziříčí - Lhotka), the mechanical properties of the upper and the lower layer of the concrete cover and measuring the resistance of concrete against chemical deicing agents.

Administrativní budova / Administrative building

Adámek, Lukáš January 2017 (has links)
The thesis deals with design of new administrative building, which supposed to serve as headquarters of midsize company with approximately 100 employees. Concept of the building with two overground floors and basement would meet requirements of growing corporate structure, company representation and modern working environment. Rectangular shape of the building allows future dispositional reconstruction and modernization. This layout allows to simplify solution of technical equipment. On the first floor of 870 square meters is facility for employees and clients located including technical background of the building as well. The underground floor is designed as storage, technical background and civil protection shelter. On the second floor are employees and management´s space located. The structural system of the building is composed of reinforced concrete skeletal structure casted in situ. Cladding of the underground section is designed as monolithic concrete walls. Upper part cladding is designed as ceramic masonry walls. The building facade is a combination of smooth aluminium panels, aluminium windows and glass facade with transparent and opaque parts. The main carousel entry is located in the glass facade part.
