Clayton First semester 2008 (Day)
This unit aims to develop an understanding of the analytical methodologies used in strength and stiffness assessment of aircraft structures. The unit will develop an understanding of the translation of aerodynamic and ground loading on aircraft wings and fuselage to the overall airframe. An understanding of the concept of structural idealisation and constraint will be developed along with real-world limitations. The principles of stressed skin construction will be considered in detail. The unit aims to develop an understanding of the analysis and design of structural problems common in the aerospace industry. It will provide students with the tools necessary to analyse aircraft structures.
Understanding of the relevance of strength and stiffness aspects of aircraft structures and components, including stressed skin construction.
Appreciation of a range of modeling tools and analytical methodologies currently used in the aerospace industry.
Understanding of the interaction between, often conflicting, requirements in the design of airframes i.e. aerodynamics, avionics and propulsion.
Knowledge and skills to translate real-world forces into abstract form for engineering modeling of airframes.
Understand the concept of loads and load paths on the airframe and the structural requirements of airworthiness.
Knowledge of alternative analytical tools to solve similar airframe problems.
Apply and contrast a range of analytical tools currently used in the aerospace industry.
