Overview of the development of small and medium lauchers
Dítě, Radovan ; Petrásek, Miloslav (referee) ; Daněk, Vladimír (advisor)
This bachelor's thesis describes the development of small and medium vehicle launchers. The dissertation is divided into four main parts. The first part deals with basic principles of rocketry and types of rocket propulsion. The second chapter describes historical develop-ment of rocketry. The third part describes the development of small and medium vehicle launchers. And the last part is dedicated to the description of current states of small vehicle launchers.

An overview of atmospheric carriers for launching satellites into Earth's orbit
Bačová, Alena ; Petrásek, Miloslav (referee) ; Daněk, Vladimír (advisor)
This bachelor´s thesis is dealing with an overview of aircrafts designed as a launch platform for an air launch of satellite into the low Earth orbit. The thesis is divided into four main parts. The first part describes main principles of reaction engine and its two types of engines. The second part provides an overview of aircrafts as launch platform in the USA. The third part deals with these launch platforms in the former SSSR. The fourth part is devoted to aircrafts as launch platform in the Europe.

Overview of the dwvelopment of new reusable space vehicles
Rohánek, Jan ; Junas, Milan (referee) ; Daněk, Vladimír (advisor)
This thesis focuses on the development of reusable space vehicles. The introduction describes history of cosmonautics. Next chapter talks about history of Space Shuttles and then names and compares the most import projects of USA and USSR. Next topic of this thesis is about problematics of reusable rocket carriers. Last chapter names and describes today´s projects of new space shuttles. The conclusion consists of overall assessment and forecast of future reusable space vehicles development.

Flying atmospheric carrier for rocket launches
Musil, Tomáš ; Mašek, Jakub (referee) ; Daněk, Vladimír (advisor)
The main objective of this thesis is to introduce the reader to the problematics of air-launch and to a custom design solution applying this concept. The specifics of this method of bringing a payload into orbit are described and explained. Overview of projects which use aircraft to launch spacecraft is included. Determination of primary parameters of a launch vehicle designed to carry a payload of a specified mass is conducted. The required flight performance has been estimated, a computational model has been developed in software MATLAB, and a multidisciplinary optimization of the design parameters has been performed using a genetic algorithm optimization method. Parameters of the designed air-launched rocket are compared with those of a ground-launched rocket. According to the specific criteria, the Airbus A310-300 aircraft was selected as the most suitable transport aircraft to be used for launching the designed launch vehicle. The last part of the thesis is devoted to the proposal of necessary modifications and estimation of the flight performance.

Overview of current spaceships
Špačková, Jana ; Daněk, Vladimír (referee) ; Zikmund, Pavel (advisor)
Target of this work is to create an overview of commonly used and in this time developed transports used for carrying payload to space and comparing these transportation means. First part of the work is divided into three sections, rockets reaching the Earth’s orbit, rockets flying bellow it and other means of space transport. These sections are further sorted by states and its stage of development they are currently in. Second part of the work is focused on comparing previously described transports from the perspective of safety, power and also costs needed for running and manufacturing them. In the end there are results from the comparing section of this work and comments on the probable path of the near future development of the space transportation.

Reusable launcher flight mission
Metelka, Dominik ; Daněk, Vladimír (referee) ; Zikmund, Pavel (advisor)
Tato práce je rozdělena do dvou hlavních částí, které jsou také hlavní cíle. Cílem první části je popis mise vícenásobně použitelného prvního stupně nosné rakety. V této části je nejdříve přiblíženo téma znovupoužitelných kosmických systémů a jejich vývoj do současné doby. Hlavně jsou však v této části popsány operačně používané vícenásobně použitelné nosné rakety, kde u každé z nich je poté popsána jejich letecká mise. Dále jsou zmíněny některé důležité nosné rakety ve vývoji a také jaké jsou způsoby návratu prvního stupně. Druhá část je praktická a cílem je návrh mise návratu prvního stupně nosné rakety na zemi. Pro výpočty byly zvoleny parametry podle současné rakety Falcon 9, ze kterých byla analyticky vypočtena finální rychlost a výška, ve které se první stupeň oddělí od zbytku rakety. Pro návrat a celkový let byl pomocí programu MATLAB napsán skript, který vypočítal a vykreslil potřebné parametry a charakteristiky. Díky tomu bylo také zjištěno, v jaké výšce bude potřeba znovu zažehnout motory, aby první stupeň bezpečně přistál na zemi.
