| 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. |
|
| Course objective : | 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 modelling of aeroelastic systems
- Study of static divergence
- Study of flutter
- Study of control efficiency and control reversal
- Introduction to flight flutter testing
- Study of supersonic aeroelasticity |
|
| Prerequisites : | -AERO0001-1 Aerodynamics
-MECA0029-1 Theory of vibrations |
|
| Workshops : | Matlab workshops on:
- Aeroelastic simulations
- Flight flutter testing
Worked examples in every lecture |
|
| Organization : | This is a first semester course. It is divided into 6 structured learning sessions and two Matlab workshops.
A structured learning session is a combination of traditional lecturing with tutorial examples given to the students and solved with the assistance of the lecturer. |
|
| Written notes : | The lecture notes are available online in the form of Powerpoint presentations.

|
| Assessment : | Assessment is performed through:
- A written exam
- An oral exam
- Assessmet of the students' work during the Matlab workshops |
