Unmanned Aerial System design competition
Malinowski, Matěj ; Navrátil, Jan (referee) ; Pejchar, Jan (advisor)
Bakalářská práce se zabývá návrhem malého bezpilotního letounu určeného pro soutěž Air Cargo Challenge 2015. Práce je uspořádána dle postupu vývojových prací. Na prvotní koncepční návrh navazuje volba vhodného tvaru letounu a jeho profiláže. Následuje výpočet letových výkonů, maximální vzletové hmotnosti a centráže letounu. Poslední část práce se zabývá konstrukcí letounu a je provedena analýza závislosti užitečného zatížení na hustotě vzduchu.

Competition aircraft F1A wing design
Jurina, Marek ; Pejchar, Jan (referee) ; Hájek, Tomáš (advisor)
This thesis deals with wing design of competition category glider F1A. Flight modes are analyzed. The following part deals with aerodynamic design of wing with the use of XFLR5 software. Maximum load is defined and its distribution along wing span. Thesis also include design of internal layout with the selection of materials. Stress analysis is executed by analytic method.

Aerodynamic components of Formula 1 vehicles
Mazáč, Petr ; Beran, Martin (referee) ; Vančura, Jan (advisor)
This bachelor’s thesis deals with research themed aerodynamic components of Formula 1 vehicles. The beginning of the thesis is focused on basic of aerodynamic and generating downforce. Afterwards it deals with developement of aerodynamic from the beginning of Formula 1 to the present time, followed by categorization of the various aerodynamic elements which were used on vehicles throughout the history of the sport and in the present time with their construction description. It also summarizes active aerodynamic components.

Formula Student Car Aerodynamic Analysis
Koňařík, Josef ; Svída, David (referee) ; Vančura, Jan (advisor)
The aim of thesis is to devise the body due to the current model in the 3D software ProEngineer and given by current Formula Student competition rules. Subsequently, the model will be created for the purposes of CFD software for numerical analysis of aerodynamics. Based on this analysis, the simulation will be obtained with the coefficient of air and axles load.

The utilization of reverse engineering in computation of vehicle aerodynamics
Rozsíval, Jan ; Forman, Matěj (referee) ; Porteš, Petr (advisor)
The vehicle body was measured by using ATOS 3D scanner. Measured data from the ATOS 3D scanner were applied to make a 3D model of vehicle body and to make a 3D model of whole vehicle by using computer program Pro/ENGINEER. The model of vehicle was made with a view for future use of CAD model. Surface of the vehicle model was used for computation of vehicle aerodynamics – aerodynamic static pressure distribution by using CFD software Star-CCM+.

Sports car rear wing numerical optimization
Feldová, Petra ; Rudolf, Pavel (referee) ; Štefan, David (advisor)
This master’s thesis is focused on optimization of rear wing of sport car by using open-source software. The optimization of 2D profile of the rear wing is present in this thesis. Python environment was chosen for optimization and evolutionary algorithm was is used as optimization function. This algorithm is further connected to Xfoil software, which is computing aerodynamic characteristic. The ratio of the lift and drag coefficients (C_L/C_D) is chosen as parameter which considers the aerodynamic efficiency. The CFD computation of flowing around the whole car is provided in open-source software OpenFOAM. . The profile optimization results to approximately 7.9 % raise of the parameter C_L/C_D, in the same wing stability. The main benefit of this work is to use open-source software for the optimization and CFD analysis, which in future might save company’s resources by not buying expensive commercial software licenses.

Physical Simulation of a Cloth
Řehánek, Martin ; Juránek, Roman (referee) ; Navrátil, Jan (advisor)
This bachelor's thesis concerns with simulation of material in real time. By material we mean the textile. Firstly, it will explains principle of simulation in textile, where the system of springs is used. Secondly, it will explains mathematical and physical basics needed for simulation and then describes implementation of simulation itself. In a final part the achieved results are evaluated.
