Competition aircraft wing tips
Zima, Martin ; Koutník, Tomáš (referee) ; Doupník, Petr (advisor)
This bachelor thesis deal with wing tip design of airplane for competition. Airplane named FabricK I is design for Air Cargo Challenge competition. The first part of bachelor thesis is focused on description of competition and flight aircraft modes. Hereafter are compared the types of wing tips. Most suitable wing tip is then applied on FabricK I.

Korytář, Jan ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
The aim of the work is a general description of the effects on air traffic and aircraft. The first part of the work is devoted to a brief description of the development of individual technical parameters and performance of aircraft from the 1920s to the present with an assessment of the effects. The second part of the work is about the influence of current requirements and the third part is a general view of the future development of construction and technology for more economical and environmentally friendly air transport

Aerofoil Aerodynamic Features Optimization
Müller, Jan ; Rozehnal,, Dalibor (referee) ; Popela, Robert (referee) ; Zelinka, Ivan (referee) ; Ošmera, Pavel (advisor)
The content of the presented thesis is advanced optimization of the aerofoil wing of a general aircraft. Advanced metaheuristic optimization techniques based on evolutionary calculations and swarm algorithms are used for optimization. These algorithms are characterized by robustness of optimization and engineered degree of convergence and optimality of the solution. Within the solution, fundamental modifications of the original aerofoil optimizations were designed and implemented. A new variant of aerofoil evolutionary algorithms (aEA) was created from the original evolutionary algorithm (EA), followed by a new variant of aerofoil particle swarm optimization (aPSO) developed from the original particle swarm optimization (PSO). Then the hybridization of the mentioned methods was created in a parallel variant. The Bezier-PARSEC 3434 parameterization model that generates the aerofoil shape was used for the optimization process. A parametric model based on B-Spline was used to optimize the original aerofoil. Fluid dynamics simulation for the calculation of basic aerodynamic features (lift, drag, moment) was realized by Xfoil software. The results are then verified using fluid dynamics simulation (CFD ANSYS Fluent). From the point of view of optimization tasks developed by optimization and implementation, it is clear that this is a complex interdisciplinary task, the results of which are presented in this thesis.

The growth and development of wings during ontogeny with emphasis on Palaeodictyoptera
Rosová, Kateřina ; Prokop, Jakub (advisor) ; Sroka, Pavel (referee)
The series of two fossil species belonging to the order Palaeodictyoptera from the Late Carboniferous of Kuznetsk Basin in Russia were re-examined. The two species as Tchirkovaea guttata and Paimbia fenestrata were investigated with emphasis on the wing growth and development in comparison with the structure of developing wings in recent mayflies. This fossil material of T. guttata and P. fenestrata was long considered by previous authors as undisputed evidence for a unique type of wing development in the Palaeozoic insects. The idea was that the larvae of these insects possessed the wings, which became articulated and fully movable already earlier during the postembryonic development and that these gradually growing wings changed their position from longitudinal to perpendicular to the body axis. Moreover, the development was supposed to include two or more subimaginal instars, implying that the fully winged instars moulted several times during postembryonic development. After detailed study of the available fossils and subsequent comparison of the fossil evidence with the development of wings in the recent mayfly Cloeon dipterum it was discovered, that the alleged series of immature, subimaginal and imaginal wings of T. guttata and P. fenestrata do not provide clear evidence that would support...

Construction parts and Elements of the of Large transport aircraft Wing structure
Malcová, Alica ; Vaněk, František (referee) ; Juračka, Jaroslav (advisor)
Wings are a complex aircraft structure and must meet various requirements, such as aerodynamic, strength and technological requirements. When designing the wings, great consideration is given to the structure and the materials used. This bachelor’s thesis focuses on the design of the wings of large transport aircraft and its execution. The individual parts of the structure are systematically arranged and explained. The work is divided into certain sections starting with the general requirements for the wing, followed by the choice of materials used, the internal structure, individual elements of the wing and structural hitch of the wing. At the end of the work, I point out the differences and similarities in the construction and materials used for the metal and composite wings. For a better understanding of the issue, the work is supplemented with pictures and a diagram. The appendix of the thesis is a presentation intended for educational purposes.
