Design of aircraft power unit
Poledno, Martin ; Maňas, Pavel (referee) ; Nevrlý, Josef (advisor)
This diploma thesis deals with basic design and calculation of an aircraft power unit (APU). For desired shaft power the thermal cycle is calculated. Basic dimensions of compressor, turbine and exhaust system are calculated as well as thermodynamic parameters of air and hot gases along the motor. Corresponding compressor map, turbine map and characteristics of the exhaust system are designed. Based on these characteristics, an effective shaft power is being calculated in various off-design conditions. Dependency of the shaft power vs. altitude is also presented. All the calculations are made in MATLAB. Finally, simplified motor cross-section is created.

Electrical integration of an auxiliary power units for truck
Pšenčík, Petr ; Veselý, Ivo (referee) ; Beneš, Petr (advisor)
This thesis aims to hardware and software integration of solid oxide fuel cell into a power generator for truck application. Requirements for individual components are defined, especially for main DC/DC converter which allows charging the battery pack with output from fuel cell. Then suitable components are found on the market and incorporated into hardware layout. Operation strategy with safety concept is proposed and consequently integrated into PLC in LASAL Class 2 environment. This is followed by definition of future work which includes testing and possible changes in components. Result is hardware and software design which allows construction of prove-of-concept prototype.
