Aerodynamics

ME-445 / 4 crédits

Langue: Anglais

Summary

This course will provide the fluid dynamic background to understand how air flows around two- and three-dimensional wings and bodies and to understand and calculate the aerodynamics forces and moments acting on the objects as a result of the air flow.

Learning Outcomes

By the end of the course, the student must be able to:

Describe the physical behaviour of a flow in scientific terms, AH1
Link flow behaviour with non-dimensional parameters (e.g. Reynolds and Mach numbers), AH2
Describe the physical differences between laminar and turbulent flows, AH4
Describe in detail the physical phenomena associated with the interaction of a flow with a solid wall (as a function of its characteristics, e.g. roughness), AH5
Describe flow in simple geometries, such as over a flat plate, in a tube, or around a sphere or airfoil, AH9
Work out / Determine the flight characteristics from a wing shape and chose a wing shape to provide the desired flight characteristics, AH10
Describe 3D effects resulting, for example, from a finite wing span or behind a blunt body, AH11
Solve analytically or numerically the potential flow around an airfoil, AH19
