Aerodynamic analysis of low orbit launcher
Fojtl, Michal ; Navrátil, Jan (referee) ; Popela, Robert (advisor)
Master’s thesis deals with aerodynamic heating of launch vehicle during ascent phase by using CFD simulation. Ascent trajectory and payload fairing geometry is design using data of existing small launch vehicles. Critical flight regimes are identified using 2D calculations, and in these regimes analysis is performed by axially symmetric simulations. Simulation results are compared to values obtained from theoretical and semi-empirical calculations.

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.
