Aerodynamic analysis and design modifications of L 410 NG aircraft wing-fuselage junction
Derevjanik, Šimon ; Pejchar, Jan (referee) ; Popela, Robert (advisor)
This thesis deals with CFD analysis of a wing-fuselage junction on L410NG airplane. Possible modifications are proposed as well. Calibration problem solved in the introduction serves as a pathway for validation of the results and gives insight into the CFD methodology. The main part analyses the airplane's flow field and shows the details of the modelling process. Description of the computing network followed by final evaluation is presented. Next part is devoted to the creation and aerodynamic analysis of the modified geometry. Final part of the work compares both basic and modified geometry.

Preliminary aerodynamic analysis of remotely controlled model with jet propulsion
Novák, Ondřej ; Zikmund, Pavel (referee) ; Popela, Robert (advisor)
This bachelor´s thesis deals with aerodynamic analysis of unmanned aircraft and subsequent changes to design of wing, its position and wing-fuselage junction. In this work emphasis is laid on flow separation, its interaction with other flow structures and its influence on aerodynamic properties. The goal of these changes to the aircraft is ensuring sufficient stability and controllability in low as well as high angle of attack flight. AVL, XFLR5 and CFD methods were used in the thesis. In case of inaccuracy of CFD calculation, two backup wing related modifications were prepared.

Aerodynamic design and analysis of "Twin Shark" glider
Krmela, Luděk ; Kouřil, Martin (referee) ; Popela, Robert (advisor)
The thesis contains determination of real aerodynamics characteristics of PW09-135 flap airfoil with help of calibration method via CFD, followed by accomplishment of CFD analysis of parts and the whole Twin Shark glider. Detailed research and optimization was made to flow field quality of fuselage and wing fuselage junction. On the basis of CFD solution was determine a stability control, static margin and angle of attack of a horizontal stabilizer. The thesis concludes an evaluation of results applicability in praxis.
