Contenus de l'unité d'enseignement

The purpose of the lectures is to introduce the design of semi monocoque structures used in aeronautics. Three domains are studied:

• Structural idealization: Analytical models of wing and fuselage based on thin-walled section beam.
• Thin structures models: Theory and introduction to finite-element model of plates and shells.
• Introduction to buckling of thin structures.

Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

The student will have acquired the methodology required to conduct a preliminary study in the context of aircraft structures. In particular:

• He will have a deep understanding of the thin-walled beams and thin structures theory and will be able to summary, compare and explain them.
• He will have a deep understanding of the resolution methods of thin-walled beams and thin structures buckling problems, and will be able to summary, compare and explain them. He will also know their application range.
• He will be able to apply the resolution methods to classical problems.
• He will be able to analyse and to evaluate (justify and criticise) these methods.
• He will be able to analyse new problems.

Savoirs et compétences prérequis

Good knowledge in

• Solid mechanics

• Finite-element method
• Aerodynamics

Activités d'apprentissage prévues et méthodes d'enseignement

Exercises and personal project. A major part or the totality of the personal project is achieved in the context of the APRI0004 class.

Lectures recommandées ou obligatoires et notes de cours

• Aircraft Structures for engineering students T. H. G. Megson, Butterworth-Heinemann, An imprint of Elsevier Science, 2003, ISBN 0 340 70588 4
• Lecture notes on http://www.ltas-cm3.ulg.ac.be/classes.htm

Modalités d'évaluation et critères

Evaluation is based on the realization of a project (30%) related to the design and/or modeling of a semi monocoque structure and on a written examination (70%). For the resit, if a grade of at least 10/20 has been given to the project, only the written examination will be redone.
Amajor part or the totality of the personal project is achieved in the context of the APRI0004 class. The grade of the related part of the APRI0004 project will be used for this class project grade.
The examination is based on the whole content of the class. Problems similar to the ones studied during the classes, and new problems will be part of the questions. Justification using the theoretical content is also asked.
Participation to the exam, to the guest lectures, and achievement of the project are mandatory. The student who does not attend to compulsary sessions or who does not delivered the assignements on time will not be allowed to present the exam.
