This is a first course on the principles of aeroelasticity with the objective of providing the trainees with a sound conceptual and analytical foundation in aeroelasticity. The trainees will learn about the interdisciplinary nature of aeroelasticity, different aeroelastic instabilities, such as flutter and divergence, and how to develop/use some mathematical tools to predict instabilities for simple configurations, such as typical airfoil sections and uniform wings. The course will also give an overview of different aerodynamic theories, such as steady, quasi-steady and unsteady flow theories, which are used for aeroelastic analyses. In addition, the trainees will learn how to use MATLAB to implement different flutter prediction methods, such as p, k and pk methods.
