Continuous wing design for a high-performance glider
 Přikrylová, Helena ; Bartoněk, Jaroslav (referee) ; Juračka, Jaroslav (advisor)
The vast improvements in the field of aerodynamics and materials in the recent decades have brought significant changes in the geometry of sailplane wings. From the structural point of view, the maximum thickness of the used airfoils has decreased which in turn caused lowering the height of a spar. That necessitates strengthening of the spar flanges which again leads to shortening the distance between their opposite surfaces hence shortening the shear webs as well. Together with the need of sectioning in the cases of gliders with larger wingspans a question arises as to whether the conventional single spar design with wing connections in the glider’s longitudinal plane of symmetry by means of heavy spar extensions is the best possible solution. This thesis proposes a continuous wing design of a high-performance glider with the use of a two-spar and multi-web structure implementing a focus on determining of an appropriate sectioning.

Aircraft lifting surface morphing
 Přikrylová, Helena ; Juračka, Jaroslav (referee) ; Dubnický, Lukáš (advisor)
This bachelor’s thesis deals with the introduction of morphing wing technology, more specifically camber morphing. It describes the specific requirements in terms of different construction parts by presenting various morphing concepts. The first part is dedicated to brief description of the motivation for wing morphing, that is followed by introducing different morphing concepts that use kinematic or compliant mechanisms in order to achieve shape changes of the airfoil. The need of anisotropic skin and several ways of achieving the anisotropic behaviour are described as well as the pros and cons of the use of conventional actuators and innovative smart materials. The last chapters deal with the validation of morphing wing benefits and the demonstrations of the feasibility of the morphing concepts.
