Development in pure jet engine and production survey
Štefanovič, Peter ; Koštial, Rostislav (referee) ; Šplíchal, Miroslav (advisor)
The main object of this bachelor thesis is a comprehensive review of jet engines. The thesis briefly explains the broad issue of gas turbines in terms of their operation and various advantages and disadvantages. Then it presents particular application areas. At the beginning it notes the history and introduction of jet engines to the significant field of aviation. The main part focuses also on the current manufacturing of individual types of engines with technical data. In the last section there are classified provisional steps which could affect or improve some parameters. In the end of the bachelor thesis trends and developments are suggested.

Evaluation of dynamic damage of composite structure
Štefanovič, Peter ; Jetela, Václav (referee) ; Klement, Josef (advisor)
The first part of the diploma thesis with name „Evaluation of dynamic damage of composite structure“ focuses on designing device for impact experiments and suitable laminate samples made from prepregs. The conditions and problems of impact tests are also demonstrated here. The second part of the thesis deals with non-destructive control of damaged specimens based on thermography. This is mainly the extent of defects in the impaired area and the evaluation of results using the pulse infrared thermography method. Finally, the relative deviation in the crack size comparison between the visual method and thermographic are compared. Consequently, the residual strength of the damaged samples against undamaged specimens are compared using bending tests.
