Design of hydrogen jet engine to 1kN thrust
Mikulenka, Karel ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
This thesis includes a brief history of jet engines using hydrogen as fuel. Calculation of thermodynamics of small engine with thrust up to 1 kN which is in modern day used in practice drones or ballistic missiles will be conducted. Given initial parameters compressor selected is of radial type. Calculation of radial compressor and its verification in EES software. Issue of combustion chambers is presented and calculation of chamber balance is carried out. Computation of turbine and blading layout. Proposal of jet for expansion into atmosphere and engine thrust. Comparison of contemporary projects researching hydrogen propulsion in aerospace with their conventional counterparts and assessing their feasibility compared to other types of renewable fuels.

Inverted Aircraft Engines
Růžička, Martin ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This thesis deals with inverted aircraft engines. Introduction contains overview of general requirements for aircraft engines, their division and basic information about inverted construction. In second chapter there is overview of selected engines with inverted construction, their description, technical specification and eventually modifications. Conclusion consists of chapter elaborating on description of different construction and their comparison with performance-wise similar invert engines.

Simulation model of an aircraft internal combustion piston engine
Olšovský, Petr ; Kučera, Pavel (referee) ; Svída, David (advisor)
This master’s thesis deals with creating a real-time simulation model of an aircraft piston engine with emphasis on heating and cooling of the engine cylinders. First part of this thesis focuses on characteristics of aircraft engines and differences with regular automotive engines. The next chapter describes the dependence of engine parameters on atmospheric conditions. The description of the real time model itself follows next. The results of the simulation model are presented and analysed at the end of this thesis.

Powertrain design of a four-cylinder aircraft engine
Příborský, Vladimír ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis named Powertrain of an four-cylinder aircraft engine dealing with configuration of the powertrain of a flat four-cylinder engine with ordered basic parameters. The thesis is focused on configuration design of the crank machanism and sequence ignition, balancing of centrifugal and reciprocating forces and their moment, conceptual design of crankshaft and its stress calculation. The thesis describing calculation of torsional vibration as well.

Aircraft Engines till the End of WWII
Falta, Libor ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis deals with aircraft piston engines until end Second World War. Thesis surveys about known, the most use and non-traditional types of engines in timeline. At the beginning it deals about history of aviation and the first use of piston engine as power source energy for controlled flight. There are high requirements on aircraft piston engines. Improving construction and increasing output of engines. In every chapter typical construction and the most powerful engines of the period are described. Thesis includes influence of both World Wars and some prestigious racings, which considerably accelerated global development. Explain the limit for increase output of piston aircraft engines in the last part.
