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

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Assessment is performed through: - An oral exam (70% of the final grade) - Assessed reports for the three wind tunnel experiments (group work) (30% of the final grade)
Depending on the sanitary conditions, the oral exam takes place either in class (green/yellow level) or individually at home (orange/red level) through video-conference.
The content of the lab reports is part of the oral exam (1st and 2nd sessions).
The reports must be sent on time to present the oral exam (1st and 2nd sessions). The deadline cannot be modified.
The grade for the lab reports is carried automatically  to the second session.
