Thermal simulation for space applications
Kostelník, Tomáš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master´s thesis is focused on the problem of modelling heat transfer in Earth orbit. In the theoretical part, the main types of standard orbits are described, including terminology related to this issue. Furthermore, the subsystems of space probes are described with a focus on a specific description of their functions. The thesis also includes a discussion of the issues related to thermal management of space satellites, with a focus on multilayer insulation and thermal surface finishes. The work also includes a description of the various mechanisms of heat transfer in space, with a deeper focus on thermal radiation heat transfer, which is key in the context of this thesis. The experimental part is focused on the design of a calculator focused on the computation of radiation boundary conditions for different orbits of a space vehicle and their verification using a CFD solver on a model example of a cubesat.

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.
