This course examines aerospace structural design, with an emphasis on metallic structures. The course covers: 1) certification (i.e. what is required to demonstrate that a structural component is safe and compliant with applicable regulations); 2) stress analysis techniques used to design and certify the thin walled structures which comprise most of the aircraft structure; 3) characteristics and manufacturing processes for high strength aerospace metallic materials; 4) structural optimisation in a practical context (i.e. how to design a component, in terms of materials and sizing, to have minimum weight, the required strength, and be suitable for manufacture).
This course addresses the design of metallic aircraft components, and consists of two topic areas:
- Topic 1 examines the thin-walled structures which make up most of the structure of modern aircraft. Students learn how to apply the most useful classical analytical techniques to the design and certification of these components.
- Topic 2 examines the high performance isotropic metallic materials used in modern aircraft.

Task description
This assignment is centred around design and testing of a high strength aerospace aluminium alloy, and there are two associated laboratory sessions.
The initial phase of this assignment is to be performed in groups. Students will design a heat treatment process for an aluminium alloy in order to achieve specified mechanical properties. In the first laboratory session, supplied tensile and compressive test specimens will be subjected to the designed heat treatment schedules. In the second laboratory session the heat treated samples will be mechanically tested, providing tensile and compressive stress-strain data.
Students will then submit individual reports on this work, on the material design process and experiments, including background discussion. As part of this analysis, students will use stress-strain data from the laboratory experiments to derive mechanical properties for the alloy.
If, for whatever reason, you find that your group is not functioning effectively, please contact your Course Coordinator for support.
You must attend the laboratory sessions to receive all available marks for this item of assessment. If you cannot attend the practical then you need to apply for an extension. This may result in you either being allocated to a new practical time, or else being approved to submit the assessment subject to alternative arrangements, to be determined by the Course Coordinator. Where a student fails to attend their group's practical's without an approved reason, “Experimental Procedure”, “Results and Discussion” and “Conclusions” sections of their assignment will be marked as zero (where they were absent from both practical's) or else each mark against these criteria will be reduced by 50% (where they were absent from one practical).
