Design of the system for the carbon composite conductive layers of the L-39NG aircraft testing and the optimization of the conductive material
Pham, Ngoc Nam ; Hönig,, Martin (oponent) ; Háze, Jiří (vedoucí práce)
In recent decades, the use of composites has been dramatically preferred in the aerospace industry. The latest projects of the Czech aviation industry also focus on increasing the use of composites in new aircraft. This thesis focusses on the research of the electrical properties of the composite in order to optimize the choice of material. The thesis presents the design of an automatic measuring station used for measuring and testing the electrical properties of composite specimens produced by the company AERO Vodochody AEROSPACE a.s. For this purpose, the device LCR bridge R&S HM8118 is used, and the control program is designed in the MATLAB environment by using the SCPI language. The proposed system is then used for experimental verification of the electrical conductivity of composite samples. The measurement results will be the basis for the development of aviation conductivity composites in new aircraft. This thesis also presents the results of the lightning strike test on the selected composite specimens. Results of the lightning strike test provide deeper knowledge about the lightning strike protection ability of specimens. The development of a Non-destructive testing system based on the method of Electrical Impedance/Resistance Tomography is also presented in this thesis. The development is in the first stages, but the system is expected to be used as a structural health monitoring system.

Posouzení ekonomických ukazatelů společnosti pomocí statistických metod
Miloševský, Filip ; Zamcová, Hana (oponent) ; Doubravský, Karel (vedoucí práce)
Bakalářská práce se zabývá posouzením finanční situace podniku Aero Vodochody AEROSPACE a.s. Hodnotí výkonnost a zdraví podniku podle výstupů účetnictví. Znalost historických dat, jejich správná interpretace a prognóza poslouží pro strategické a plánovací účely podniku. V práci je využito metod analýzy časových řad a regresní analýzy pro posouzení trendu a stanovení prognóz na příští období. Pomocí těchto metod budou stanoveny hodnoty, jež by podnik měl v jednotlivých letech dosahovat.
