Fatigue Life Evaluation of Composites Structures
Mihalides, Dušan ; Kopřiva, Tomáš (referee) ; Juračka, Jaroslav (referee) ; Klement, Josef (advisor)
The doctoral thesis deals with fatigue life evaluation of composites structures. The thesis pro-vides complex review of problematic and it is based on recent situation assessment. The main ob-jective of the thesis is to design the methodology of fatigue life evaluation of composites struc-tures. The designed methodology is applied to fatigue life evaluation of sailplane wing and propel-ler blades. One part of the thesis deals with laboratory fatigue tests of composite specimens which are intended for comparison of the effect of manufacturing technology and environment condition.

Wing design of the gliders
Löffelmann, František ; Weis, Martin (referee) ; Jebáček, Ivo (advisor)
Thesis treats influences of geometrical characteristics on aerodynamic wing properties generally meaning, wing construction load and describes typical wing design. Next there are introduced basic requirements on gliders, according to regulation CS-22. Consequently there are described composite structures and there is sketched their design. There are described wings of two different present high-performance sail-planes (Schleicher ASW 22, SZD56-2 Diana-2). Finally there are compared modern gliders, their performances and on this basic there are compared performances of 15-metre Class and 18-metre Class.

Development and use of non-motorized aircraft
Bečka, Pavel ; Schoř, Pavel (referee) ; Zablatzký, Jiří (advisor)
The object of this bachelor thesis is history, development and use of non-motorized aircraft. The first part dedicate of history this aircraft industry in the Word and Czechoslovakia. The second part dedicate about construction of this machines. The Thirst part dedicate of materials, which are using in this part of aeronautical production. And finally fourth part dedicate ways for starts of this aircrafts.
