Efficiency incerasing of axial compressors of jet engines
Fojtl, Michal ; Weis, Martin (referee) ; Šplíchal, Miroslav (advisor)
Bachelor thesis deals with axial compressors of jet engines and with increasing their efficiency. First part describes basic principles of compressors, losses, stall and surge and compressor characteristics. Second part deals with possible solutions for increase of their efficiency and pressure rise. These solutions are summarized and possible combination is recommended.

Modeling and control of aircraft jet engines
Voda, Tomáš ; Blaha, Petr (referee) ; Veselý, Libor (advisor)
This thesis deals with the description of aircraft engines, their control requirements and control possibilities of these engines. In the practical part, the Jetcat P80-SE engine model was created. This model was then verified against a real engine with measured actual engine speed and temperature. These parameters were then compared with simulated engine speed and temperature. Due to this comparison we can say that it was possible to create a model of the engine that corresponds to the real engine. In addition, the speed controller was designed to meet the control requirements over the speed range. A PI speed controller was designed in different variants, the variants were then compared. Due to the safety limits of the manufacturer were not known, limit values were only implemented to show how the limitation could be implemented.
