Objectives

On completion of this module, students should be able to:
with respect to aerodynamics:
- Understand the fundamentals of engineering Analytical Fluid Dynamics (AFD) and Computational Fluid Dynamics (CFD) and their application to the design of aerospace systems;
- Extend fluid mechanics concepts from unified engineering to the aerodynamic performance of wings and bodies in subsonic regimes;
- Apply the aerodynamics concepts studied to modelling flow around aircraft wings using first principle modelling and software packages.

with respect to aircraft design and construction:
- understand how design, materials and construction combine to enable the manufacturing and operation of airframes and propulsion systems;
- understand the design process and important design tools and how these impact the nature of modern civil and military aircraft;
- appreciate the importance of materials and selection in the design of civil and military aircraft and how this has influenced historical development of aircraft;
- be familiar with the principles and applications of aviation materials;
- understand major methods of aircraft construction;
- understand the interplay between economic and performance criteria in aircraft design, materials and process selection;
- appreciate the design, materials selection and manufacturing processes for major components of aircraft;
- appreciate the significance of incorrect selection of materials or process routes and how this leads to failed aircraft projects;
- apply all of the above to specific types of aircraft.

Learning outcomes
Students should:
- understand the aerodynamics of aircraft and space vehicles, lift, drag and the application of computational fluid dynamics (CFD) in this field;
- have an appreciation of computational algorithms in aerofoil theory to predict aerofoil performance under subsonic flight conditions;
- have a basic knowledge of compressible gas dynamics and solutions to compressible flow;
- understand the fundamentals of CFD and the use of CFD software in aviation applications;
- gain an understanding of how aircraft are designed and constructed, encompassing both aerodynamic and broader aspects;
- gain the ability to apply this aircraft design and construction knowledge to the development of requirement specifications and conceptual designs for aircraft.
