Valves of the rocket fuel systems and engines
Kadlec, Jan ; Štefan, David (referee) ; Kozák, Jiří (advisor)
The main aim of this bachelor thesis is developing a search about rocket valves. For better understanding of the function and position valves is chosen a real rocket engine. The types of valves are described by shape of closing component. There are also mentioned the most common rocket fuels. The other aim is developed a simple design of shut-off valve with specialization on hydraulic losses.

Adjusting mechanism of a small rocket engine for space exploration vehicles
Vrana, Andrej ; Popela, Robert (referee) ; Bartoněk, Jaroslav (advisor)
This bachelor’s thesis deals with designing adjustable gimbal mechanisms used for steering a small rocket engine and their depiction in 3D CAD models. The thesis is divided into two main parts. In the first part, spacecraft used for exploration of celestial bodies are described. All the spacecraft are described in detail, showing their mission phase, their design and technical parameters together with informations about their scientific discoveries, which they provided. The second part describes how rocket engines work with their division into main types and gives examples of rocket engines used in the aerospace industry. Furthermore, means of steering a rocket during flight are described, with also showing various ways of dealing with this issue. Finally, designs of of adjustable gimbal mechanisms are presented, with description of their usability.

Rocket Engine Design
Cejpek, Jakub ; Konečný,, Pavel (referee) ; Třetina, Karel (advisor)
The objective of this study is to design a solid rocket fuel engine with sufficient power to propel 500 grams to 1500 meters of altitude. Furthermore to draft a design of a rocket that will utilize this category of solid rocket fuel engine. This study will begin with a theoretical exploration of the means to formulate the correct propellant closest to the theoretical solid rocket fuel formula. This section of the exploration will exclude the construction materials, technology, and the propellant availability. After the theoretical exploration the calculations will continue, respecting the availability of construction materials, technology, and the propellant; to investigate the means to formulate the correct propellant closest to the theoretical formula. Then, according to the new propellant formulation, re-design the engine.

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.

Development of rocket engines
Marcinko, Peter ; Cejpek, Jakub (referee) ; Koštial, Rostislav (advisor)
This thesis describes the development of rocket engines since the beginning to present time. The thesis is divided into three parts. The first describes the main physical principles, which have to be respected during the flight. The second part talks about the basic division of rocket engines and the used fuel types. Tle last chapter deals with Russian, American and European rocket program. It describes the main types of space rockets together with the engines they used.

Historical development of rocket engines
Šima, Dávid ; Dubnický, Lukáš (referee) ; Petrásek, Miloslav (advisor)
This bachelor´s thesis is dealing with the historic development of rocket engines and their use on rocket carriers. The work is divided into eight parts. The first part describes the principle of operation of reactive motion and derivation of the Ciolkovskij equation. The second part describes historical development from ancient China to the period before World War II. The fourth part describes the Second World War and especially the missile development in Germany during the war. The fifth part describes mainly rocket engines use in space research of the USA, Russia, Japan, the European Space Agency, India and China. The sixth part describes rocket engines of private companies which were founded in the early 21. century. The seventh part describes aerospike rocket engines and the last part describes physical engines.

Injection systems of rocket engines
Vrbica, Kryštof ; Cejpek, Ondřej (referee) ; Malý, Milan (advisor)
This bachelor thesis deals with liquid propelled rocket engine injector design. The theoretical part describes the categorisation and principles of the function of a rocket injector element. The following research part provides an in-depth examination of the most often used injectors including their possible versions. This section concerns coaxial, pintle and impinging injectors. The emphasis is laid on discharge coefficient, spray behaviour and definition of the optimal injector geometry for high-quality atomization. The thesis is concluded with a design of test injectors and their experimental comparison. Coaxial and two version of impinging injector are tested with regards to spray behaviour, their discharge coefficients, Sauter mean diameter and droplet velocity. Design drafts required for production are included in this thesis.
