## Course unit details:Aircraft Aerodynamics

Unit code MACE31321 10 Level 3 Semester 1 Mechanical and Aeronautical Engineering Division (L5) No

### Overview

Aerodynamics is the study of the interaction of air and external surfaces of solid bodies moving through it. Aerodynamic knowledge is crucial for understanding flight and for the design of efficient flying configurations. This unit teaches the behaviour of 2D aerofoils, finite wings and aircraft in both low-speed and high-speed flows. It also teaches the fundamental knowledge and inviscid flow theories that enable engineering analysis of the generated forces and moments. The unit consists of twenty hours of lectures, four tutorial sessions and a two-hour wind tunnel lab session.

### Aims

To impart in-depth understanding of the underlying physics for the aerodynamics of 2D aerofoils, finite wings and aircraft at subsonic, transonic and supersonic flight regimes.

To evaluate the forces and moments generated on 2D aerofoils, finite wings and aircraft for both subsonic and supersonic flows using classical aerodynamic theories and models.

To practise real aerodynamic measurements and complement understanding of the aerodynamic behaviours of a 2D aerofoil at subsonic speeds via wind tunnel experiments.
