EV-55 aircraft modification for water level landing
Šponer, Jan ; Vaněk, František (oponent) ; Chybík, Ladislav (vedoucí práce)
Modification of the contemporary terrestrial version of EV-55 aeroplane for the possibility of water level landing is considered in this Masters Thesis. The aim is to find a design solution which does not lead to significant structural modifications in the airframe and meet Certification Specification 23 (CS 23). Weight analysis of the modified aeroplane is made and the water loads determined in accordance with CS 23. The connecting frame is designed in accordance with water loads and stress analysis for each element and fastener is performed. These values are compared with ground loads. Finally, flight performance, such as maximal horizontal speed, rate of climb, range and endurance are determined.

Wing fatigue safe life investigation of single-engine multipurpose aircraft
Hubáček, Jan ; Juračka, Jaroslav (oponent) ; Chybík, Ladislav (vedoucí práce)
The Diploma Thesis deals with fatigue safe-life estimation of critical wing cross-section of an aircraft. The aircraft type is specified as all-metal high-wing strut monoplane. Aircraft is certified under FAR 23 Amendment 23-46 regulations. Wing safe-life estimation is evaluated in respect to methods listed in FAR 23 and its advisory circulars. \\ The theoretical part of diploma thesis reviews the project bases and literature. It briefly introduces project background, reasons for fatigue life calculation and aircraft subjected to fatigue analysis. Subsequently literature review was focused on requirements of standards, advisory circular documents and and research in field of fatigue life. \\ Second part of the thesis is focused on a computational analysis and a software development. First sub-part of computational analysis includes preparation of input data, including V-n diagram calculation, mission profile estimation, wing load distribution, critical cross-section stress analysis. Then detail analysis of fatigue was evaluated in respect to fatigue characteristics estimation, cumulative damage and fatigue life calculation with defined mission profile, wing safe life estimation.
