Learning outcomes of the course unit

The course Aircraft Materials makes students familiar with representative aircraft structural materials as well as with their optimal use. Students will be able to evaluate different material variants of aircraft structures according their strength, lifetime and damage tolerance.

Prerequisites

Basic knowledge of relations between composition, processing, structure and properties of structural materials. Basic terminology of physical metallurgy and material limit states.

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

The course-unit credit requirements: 90% attendance at seminars. It is also necessary to submit completed and sophisticated computational exercises. Obtaining the credit is a condition for admission to the exam. The exam is written.

Course curriculum

Work placements

Not applicable.

Aims

The aim of the course Aircraft Materials is to inform students of present state in the area of structural materials for aircraft structures and to provide them with methodical and objective knowledge.

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

Attendance at seminars is compulsory. In case of justified absence, the missed seminar may be compensated with an individual assignment. Continuous checking is made by means of written tests. In case of a failure, it is required to repeat the test.

Recommended optional programme components
