Demonstration equipment for rubber-pad forming
Kubo, Michal ; Koutník, Tomáš (referee) ; Klement, Josef (advisor)
This project elaborated within bachelor study, describes brief view of forming process with elastic instrument. These technologies are used mostly in aeronautical produce, due to its advantages. Thesis also contains design of equipment, which helps with presentation of these technologies during teaching of subject Aircraft manufacture.

Optimized design of turbine engine intake
Kubo, Michal ; Matějů, Jiří (referee) ; Popela, Robert (advisor)
This master thesis deals with design of a subsonic intake which is used to supply small jet engine integrate into the fuselage of agile small unmanned aerial vehicle (UAV). Some kinds of these intakes are listed in order to inspire and introduce future designers into this part of jet plane design. This thesis contains a small amount of theory about compressible flow, and necessary knowledge which are important to know before the very first attempt to design an intake. Two models were designed in order to prove that the theory listed in this thesis is useful and can be used as a guide in design process of subsonic intakes. Both designs have the same layout. S-duct design with one intake placed on the belly of fuselage was chosen. After CFD analysis of first model it was found that there are huge area with separated flow and vortex. Separated flow leads to big total pressure loss and pressure distortion. While designing the second model the emphasis was to avoid this vortex and improve flow conditions. This optimization was success and the second design have smaller pressure loss in compare to the first design. The difference is more than 50% at fly speed M=0,8.
