Learning unit 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 learning unit
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
Prerequisite knowledge and skills
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
Mode of delivery (face to face, distance learning, hybrid learning)
Face-to-face in English

Exam(s) in session
Any session
- In-person
oral exam
Other : Presentation of the three wind tunnel experiments
Further information:
Assessment is performed through:
- An oral exam (70% of the final grade)
- Labs: report + oral presentation (30% of the final grade)
The (3) labs are done by group of 3/4 students (same group for all labs).
The lab reports and presentation are manadatory to allow participation in the oral exam.
The grade for the lab presentations is carried automatically to the second session.
