Module summary

The module introduces to the students an understanding of aircraft loads and structures. It will provide fundamental techniques for design and analysis of aerospace structures. The module will develop students’ comprehension of how aerospace structures are designed and analysed using classical stress analysis techniques.

Objectives

On completion of this module, students will be able to:

Understand the uniqueness of aerospace structures and develop the theoretical basis of aerospace structural analysis as well as solving real-world aircraft structural problems.

Learning outcomes
On successful completion of the module students will have demonstrated the following learning outcomes :

1. Understand energy-method solutions for structural problems.
2. Analyse stiffened panels and tension field beams;
3. Understand the principles of stressed skin construction as applied to aerospace structures;
4. Carry out analysis to determine bending, shear and torsion of open and closed thin walled aerospace structures;
5. Carry out stress analysis of aerospace structures;
6. Determine and analyse the effects of structural constraints on aerospace structures.

Upon successful completion of this module the following Engineering Council Accreditation of Higher Education Programmes (AHEP) learning outcome descriptors (fourth edition) are satisfied:
7. Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering. (M1)
8. Formulate and analyse complex problems to reach substantiated conclusions. This will involve evaluating available data using first principles of mathematics, statistics, natural science and engineering principles, and using engineering judgment to work with information that may be uncertain or incomplete, discussing the limitations of the techniques employed. (M2)
9. Select and apply appropriate computational and analytical techniques to model complex problems, discussing the limitations of the techniques employed. (M3)
