Entry knowledge

The basic knowledge of mathematics, mechanics, structure and strength. Passing of OSZ-A Aircraft design course.

Rules for evaluation and completion of the course

Conditions for the course-unit credit award: participation in lessons (80% at least), presentation of the report elaboration from laboratory exercises. The exam has written (theoretical part and practical exercises) and oral parts.
Lectures are not compulsory, attendance is registrated. Exercises are compulsory, and the attendance (80% at least) is checked and recorded. The absence (in justifiable cases) can be compensated by personal consultation with the lecturer and elaboration of individually assigned topics and exercises. Individual tasks must be finished and handed in the week course-unit credits are awarded at the latest

Aims

The goal is to familiarize students with the most important airworthiness requirements, to explain the theoretical basis of tension calculations and deformation of thin-walled aircraft structures. Students will acquire theoretical and practical knowledge of stability of rods and walls.
The course enables students to realize typical calculations of aircraft thin-walled structures in non-linear areas of loading.
