The ONERA Aeroelasticity and Structural Dynamics Department (DADS) carries out turbomachine aeroelasticity developments within the elsA code, currently developed by the Computational Fluid Dynamics and Aeroacoustics Department (DSNA).For turbomachine aeroelasticity, DADS has developped on the one hand, weak coupling approaches using unsteady harmonic forced motion computations and on the other one, strong static and dynamic coupling approaches..
Techniques for coupling the calculation of the rotor's aerodynamics and its dynamics are also necessary for correctly representing the complexity of the phenomena : weak coupling, strong coupling....
