	Use GPS for in flight measurement Čížková, Markéta ; Dvořák, Petr (referee) ; Jebáček, Ivo (advisor) Bachelor thesis Use GPS for In-Flight Measurement addresses the applicability of Global Positioning System as a tool for aircraft certification. The theoretical part of thesis aims to acquire the GPS principle, it deals with accuracy of the system and methods of certification. The practical part contains a comparison of altitude measurement using GPS and Pitot-static system in a gliding flight. Detailed record

	Analýza aerodynamické optimalizační funkce, řízení a zviditelnění proudění na profilech s jednoduchou klapkou pro aplikace na větroních třídy FAI 18m Popelka, Lukáš ; Krejčiřík, P. ; Matějka, Milan ; Jensen, R. Aerodynamic criteria for assessing the performance of flapped airfoils applicable on wings of FAI 18m sailplanes were established by a questionnaire survey. CFD methods were used to calculate values of the criteria. Procedure of target function evaluation, enabling to take into account optimum flap deflection was developed and used for five different airfoils, typical for contemporary top-performance sailplanes. Possibility of drag coefficient reduction by transition control on the lower surface, while flap setting for circling, was studied. Surface flow visualization and integrating rake pressure measurement for optimum transition control was carried out on a high-performance sailplane HPH304S. Detailed record
	Řízení přechodu a odtržení mezní vrstvy na profilech a tělesech za podmínek volné atmosféry Popelka, Lukáš ; Zelený, L. The paper deals with visualisation of uncontrolled and controlled cases of boundary layer transition and separation carried out during in-flight measurements. Oil flow and tuft techniques have been applied. Influence of passive flow control devices to the performance of the entire aircraft has been established and importance of active and adaptive approach shown. Detailed record
