Aerodynamická optimalizace vysokovýkonného padákového kluzáku / High performance paraglider aerodynamic optimization

Grim, Robert January 2016 (has links)
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.

Vliv rotace kol na aerodynamické charakteristiky vozu / Influence of rotating wheels on vehicle aerodynamic characteristics

Oslizlo, Aleš January 2010 (has links)
The diploma thesis is focused on computational examination of influence of boundary condition settings in CFD software on the final aerodynamic characteristics of a vehicle. The flow analysis is carried out around a vehicle with and without the rotation of the wheels and along with the stationary and moving road. Furthermore, there is demonstrated the method of the CFD model composition and there is described the influence of rotating wheels on vehicle aerodynamic characteristics.

Architektonická studie objektů (provozně-technických a sportovně-společenských) brněnského letiště Medlánky / Architectural Proposal of Building in Area of Air Port Brno Medlánky

Otto, Karel January 2013 (has links)
Project presents the vision of the new Medlánky airport infrastructure, which is nowadays uncared, confused and without any possibility of expansion. The intention is create clear and well-arranged extensible structure. Safety of aircraft operations is the highest priority. New airport infrastructure should provide quality facilities for club members and pleasant surroundings for visitors. Every building has to declare its function on the first sight. Shapes and material solutions of primary buildings are inspired by aircrafts. Service buildings are low, flat and orthogonal. Simplicity is important, because aircrafts – machines have star part.

Aerodynamická analýza a optimalizace konfigurace letounu TL-4000 / Aerodynamic analysis and optimization of TL-4000 aircraft

Trusík, Vojtěch January 2014 (has links)
This master´s thesis is focused on aerodynamic analysis of 3D configuration of aircraft TL – 4000 and designing shape modifications to improve flight performances. Modifications are focused on wing – fuselage junction and junction between tail units. In continuation are analyzed the shapes of air intakes to cooling engine. Based on aerodynamic analysis of aircraft TL – 4000 are chosen convenient positions for pitot-static tube and inlets for ventilation of cabin.

Experimentální identifikace aerodynamických vlastností vozidla jízdní zkouškou / Experimental identification of aerodynamic characteristics of a vehicle by on-road test

Poláš, Maroš January 2017 (has links)
This thesis deals with road loads, coastdown tests and evaluation of measured data. Thesis consists of two main parts: theoretical and computational. The first part describes road loads with focus on aerodynamic drag and lift force. In the second part, a software tool for processing the measurement per ISO 10521-1 is designed and lift force measured with running resistance method is calculated.

Návrh centrálních pružicích jednotek náprav Formule Student / Design of the central spring units of Formula Student suspensions

Hlaváč, Martin January 2018 (has links)
This master’s thesis deals with use of central spring unit at Formula Student car. Thanks to CFD simulations, aerodynamics properties of the car was found out according to different position of suspended mass. Within kinematic design of both axles a parameters of spring unit of both axles were defined as well. Whole design was made to increase overall performance of the car thanks to the aerodynamic forces.
