Sustainable Development Goals
Learning Goals
As pre-requirements, students should have obtained consolidated knowledge from Applied Mechanics I (equilibrium of rigid bodies, reactions at supports and mass geometry) and Applied Mechanics II (kinematics and dynamics of rigid bodies, work and energy).
The course of Aeroelasticity will provide students with base knowledge on the interaction between aerodynamic forces and the structural deformation on an aeronautic structure, namely along the wings and stabilisers.
In an initial phase, students are introduced to concepts of mechanics, vibrations and structural dynamics. The students shall understand and be able to apply discrete and continuum physical and mathematical models for the analysis of vibrations of mechanical systems.
In a second phase, students will acquire the capability to analyse, using either analytical or numerical methods, the structural dynamics and aeroelasticity.

Contents
The course is divided in two modules. The first module will introduce students to the base concepts of vibrations of mechanical systems. The second module will apply these concepts to aeronautic structures and their interaction with the environment.
Module 1 (50% contact time):
1) Vibrations of discrete systems with one degree of freedom.
2) Vibrations of discrete systems with multiple degrees of freedom.
3) Vibrations of continuous systems.
Module 2 (50% contact time):
4) Static aeroelasticity.
5) Wing flexibility and divergence.
6) Wing flexibility and control.
7) Dynamic aeroelasticity. Flutter.
8) Case studies.
