Unmanned Aerial System design competition
Malinowski, Matěj ; Navrátil, Jan (oponent) ; Pejchar, Jan (vedoucí práce)
This bachelor thesis deals with a design process of small unmanned aerial vehicle intended for Air Cargo Challenge 2015 competition. The thesis is organized according to the development process. The initial conceptual design is followed by the choice of appropriate shape of the airplane and its airfoils. Calculation of flight performance, maximum takeoff weight and aircraft balance follows. The final part of the thesis describes structure of the aircraft and prediction of the payload dependence on the air density.

Aerodynamic analysis of morphing geometry application to sailplane winglet design
Malinowski, Matěj ; Jebáček, Ivo (oponent) ; Popela, Robert (vedoucí práce)
This master’s thesis deals with aerodynamic analysis and optimisation of sailplane winglet. Winglet is considered with ability of in-flight shape changing and optimisation process is focused to revealing of optimal shapes for different flight regimes. First part of thesis describes current efforts in the field of design and development of winglets with variable geometry. Second part is focused on the description of winglet function, followed by third part which describing optimisation methods, which may be used for the winglet optimisation. Description of the aircraft fitted with winglet chosen for the optimisation process is next part of thesis followed by airworthiness requirements for the category of chosen aircraft. Model of typical flight of this aircraft is next part. Rest of the thesis is organized according to the process of searching optimum winglet shapes. Wing and winglet parametric CAD model description is followed by CFD model creation process and CFD simulation pre-processing description. Optimisation process details are revealed in the penultimate chapter. The final part of the thesis contains evaluation of the optimisation process results.
