Objectives

On completion of this module, students should 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
After successfully completing this course, student will be able to:
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 UK-SPEC learning outcome descriptors are satisfied:

A comprehensive understanding of the relevant scientific principles of the specialisation (SM1m, SM7M)
Knowledge and understanding of mathematical and statistical methods necessary to underpin their education in their engineering discipline and to enable them to apply a range of mathematical and statistical methods, tools and notations proficiently and critically in the analysis and solution of engineering problems (SM2m)
A comprehensive knowledge and understanding of mathematical and computational models relevant to the engineering discipline, and an appreciation of their limitations (SM5m)
A critical awareness of current problems and/or new insights most of which is at, or informed by, the forefront of the specialisation (SM8M)
Understanding of engineering principles and the ability to apply them to undertake critical analysis of key engineering processes (EA1m)
Ability to identify, classify and describe the performance of systems and components through the use of analytical methods and modelling techniques (EA2)
Ability both to apply appropriate engineering analysis methods for solving complex problems in engineering and to assess their limitations (EA6M)
Apply their skills in problem solving, communication, information retrieval, working with others and the effective use of general IT facilities [G1]

Skills outcomes
On completion of this module students will have acquired the following skills: analytical, problem solving, mathematical derivations and solutions.
