Aircraft Materials (FSI-OLR-A)

Academic year 2018/2019
Supervisor: doc. Ing. Josef Klement, CSc.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Course contents:
Relationships between compositions,processing effects, microstructures,properties and typical applications of selected aircraft materials. Special material requirements. Aluminium alloys, magnesium alloys, titanium alloys, high strength steels, nickel-base and cobalt-base superalloys, fibre and particle composites, nanocomposites and smart systems, structural polymers,structural ceramics, wood and plywood for aircraft structures. New research and development, international material standards and equivalents.
Teaching methods and criteria:
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:
For the course-unit credit it is necessary to attend seminars and to meet requirements of three written tests. A final evaluation consists of tests results (40 %) and oral examination (60 %).
Controlled participation in lessons:
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.
Type of course unit:
    Lecture  13 × 3 hrs. optionally                  
    Exercise  11 × 1 hrs. compulsory                  
    Labs and studios  2 × 1 hrs. compulsory
