Design of equipment for measuring aerodynamically relevant parameters of passenger car tire
Kojecký, René ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This diploma thesis deals with the issue of measuring tire parameters and their impact on vehicle aerodynamics. The aim is to create a design of the tire test equipment together with a suitable method for evaluating obtained results. The theoretical part provides an overview of currently used tire testing methods. The market research follows in order to select suitable components for the proposed measuring station. The output of the practical part of the work is the assembly of the solver in the form of a Matlab script and a design with the necessary drawing documentation.

Race car bonnet shape design based on flow analysis
Šnajdr, Petr ; Kvarda, Daniel (referee) ; Michalec, Michal (advisor)
The bachelor’s thesis deals with reducing aerodynamic drag of a pneumobile. The thesis summarizes knowledge in the field of vehicle aerodynamics and the principle of CFD simulations. The essence of the work is bonnet shape design of racing pneumobile Typhoon, developed at FME BUT, for lowest possible air resistance. CFD simulations are used to observe and analyse the influence of the bonnet shape on the aerodynamics properties. The designed shape solution of the bonnet significantly contributes to the reduction of aerodynamic drag compared to the existing bonnet. Thanks to this, the vehicle’s parameters are improved from maximum speed to the range. The acquired knowledge can also help in the further development of pneumobiles and in improving the setting of the computational model described in the work.

Ground effect in motorsport
Mlčoch, Pavel ; Hejtmánek, Petr (referee) ; Čavoj, Ondřej (advisor)
This bachelor thesis describes ground effect, its influence on car aerodynamics and its use in motorsport. The thesis describes the dependence of downforce created by ground effect on the design and set-up of the race car, as well as on the downforce generating parts' relative movement in relation to the track during a race. Advantages and disadvantages of the use of ground effect aerodynamics are discussed as well. Next, there is brief summary of the use of ground effect throughout the history of motorsport. At the end, attention is paid to modern race and sport cars using the ground effect aerodynamics.
