Aeroelasticity and Structural Dynamics

Mission

To develop, adapt, evaluate and apply theoretical, numerical and experimental methods for modeling, predicting, optimizing and identifying the static and dynamic behavior of structures in their environment (structure/fluid/thermal/control coupled systems).

Research is conducted with the aim of improving performances, predicting and increasing safety and finding solutions to problems of comfort and the environment.

Areas of expertise

The areas of expertise are defined by the following main scientific topics:

designing, dimensioning and mechanically optimizing structures
technological development of new concepts for aerospace structures
dynamics and vibrations of structures including hydro-elasticity
rapid dynamics, crash, impact
aeroelasticity
vibro-acoustics

Areas of application

The areas of application include all of the products of the aeronautics and space sectors (aircraft, helicopters, turbine engines, missiles, launchers, satellites) as well as military systems and fields outside of the aeronautics and space sectors (wind turbines, civil engineering, automotive engineering, shipbuilding, etc.).

Activities

The activity is divided into a first half concerned with the development and validation of theoretical methods, by modeling and digital simulation, by updating and optimizing models and a second half concerned with the developing and implementing experimental methods and means for experimental identification and evaluation of new concepts.
