Active aerodynamic components of road vehicles
Stiborová, Dana ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
In this diploma thesis active aerodynamic components are designed, specifically brake cooling duct and active automotive wing. Cooling duct prototype and also active regulation controlling electronics including the software were created. Road test was performed to measure the duct parameters. Construction design and the active regulation function of the automotive wing were created. The influence of the wing on aerodynamic characteristics of the car was determined.

Aerodynamics of road vehicles
Mužíková, Markéta ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis deals with aerodynamics of passenger cars, racing cars and trucks too. On the basic theoretical knowledge are connected various solutions used in the practice for a particular type of vehicle. To create a comprehensive overview of this issue is there described testing of vehicles in wind tunnels and numerical techniques with using computational systems.

Coilgun
Kovařík, Martin ; Pavlík, Michal (referee) ; Šteffan, Pavel (advisor)
This bachelor’s thesis describes the design and construction of electromagnetic gun for testing projectiles from different ferromagnetic materials with maximal power 19 J. Conventional projectile propulsion mechanisms include the use of compressed air or explosion which places theoretical limits on the maximum muzzle velocity limited by laws of thermodynamics. The electromagnetic coil gun, explores the use of electromagnetism in accelerating projectiles which offers a much higher theoretical limit on muzzle velocity. In addition of an electromagnetic acceleration is possible to regulate output velocity/energy of projectile, and acceleration applied on projectile.

High performance paraglider aerodynamic optimization
Grim, Robert ; Navrátil, Jan (referee) ; Popela, Robert (advisor)
This thesis is focused on the aerodynamic analysis of the competition paraglider wing. Drags of the particular wing parts are divided into chapters. The aim was to get a grasp of sizes of the individual components drags in relation to the entire assembly. In the first instance, a 2D profile and then the entire configuration of the 3D wing was analyzed. After the evaluation, some power reserves were detected in an airfoil and so the airfoil shape was optimized. After the optimization of the individual components, the CFD calculation was used again. At the end, geometry changes were evaluated.
