Course contents :
|
| Aeroelasticity is the study of the interaction between inertial, elastic and aerodynamic forces on aircraft, bridges, wind turbines, power cables and other engineering structures. This interaction can lead to very undesirable effects such as flutter, static divergence and control reversal. A long list of engineering failures has been attributed to aeroelastic effects, starting with the Handley Page O/400 bomber aircraft in 1916. Since then there have been several high profile aeroelastic disasters such as the destruction of the Tacoma Narrows Bridge (1940) and the loss of the Helios prototype solar-powered aircraft (2003). Clearly, aeroelastic design is a crucial part of any aerospace design project. |

Learning outcomes of the course :
|
| The aim of this course is to introduce students to the subject of aeroelasticity and to the
influence of aeroelastic considerations on aircraft design.
The detailed objectives are:
- Introduction to the mathematical and experimental modelling of aeroelastic systems
- Study of static divergence
- Study of flutter
- Study of vortex-induced vibrations
- Introduction to flight flutter testing
- Introduction to stall flutter and galloping |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| AERO0001-1 Aerodynamics
MECA0029-1 Theory of vibrations |
|
Planned learning activities and teaching methods :
|
| This is a first semester course. It is divided into lectures, wind tunnel sessions and one Matlab workshop.
Matlab workshop on:
- Aeroelastic simulations
Wind tunnel experiments on:
- Vortex-induced vibrations
- Flutter
- Stall flutter/galloping
Worked examples in every lecture |
