The affect of the blade length on the swirl turbine characteristic
Pavlíček, Jan ; Hudec, Martin (referee) ; Habán, Vladimír (advisor)
This thesis deals with the evaluation of swirl turbine measurement, which the length of the turbine blades was gradually reduced. The subject of the effect was influence of the length of the blades, especially the measured efficiency of the turbine, and the character assessment of the flow at the inlet and outlet of the impeller. The measured data were analysed using the computing workbook with macro support, which can be used to evaluate other measurements of similar character. The different behaviour of the turbine depending on the length of the blades of the impeller was shown in the characteristics of the turbine and velocity triangles. For the variant with the best efficiency achieved was constructed QH diagram used in the design of turbine parameters for a particular location.

Design of small jet engine to 1kN thrust
Gongol, Jakub ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This work will be focused on issue of a jet engine. The thesis will be divided into search retrieval part and computational part. In the search retrieval part it will focus on different configurations of jet engines as well as areas of their use. The main part of the thesis will however focus on a calculations where a turbine, compressor and an exhaust nozzle will be designed in order to give a thrust of approximately 1kN. Next step will be determination of an engine charcteristic that will give us a preview on how the engine performance will look like in off-design modes.
