Learning outcomes of the course unit

The course enables students to realize typical calculations of aircraft thin-walled structures in non-linear areas of loading.

Prerequisites

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

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

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.

Course curriculum

Work placements

Not applicable.

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.

Specification of controlled education, way of implementation and compensation for absences

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
