Aircraft Structures
Overview
To provide students with an introduction to the strength of materials and their behaviour as loaded members in aircraft structures. Corrosion and fatigue is also addressed in the context of managing an aging aircraft fleet
Requisites

Learning outcomes
Students who successfully complete this unit will be able to:
- Describe and apply static equilibrium to 2D problems
- Describe aircraft structural members and materials and the method in which aircraft structures react load
- Describe the detrimental effects of corrosion and fatigue and how this is managed in aircraft fleets

Hurdle
As the minimum requirements of assessment to pass a unit and meet all ULOs to a minimum standard, an undergraduate student must have achieved:
(i) an aggregate mark of 50% or more, and(ii) at least 40% in the final exam.Students who do not successfully achieve hurdle requirement (ii) will receive a maximum of 45% as the total mark for the unit.
