Toward a Computational Framework for Rotorcraft Multi-Physics Analysis: Adding Computational Aerodynamics to Multibody Rotor Models

This paper presents a computational framework for the integrated simulation of complex multi-physics problems. It results from interfacing existing structural dynamics, multidisciplinary software and different computational fluid dynamics codes by means of a newly developed, broadly general communication scheme that accounts both for solution synchronization and field interpolation. A first application to the fluid structure interaction problem based on a free wake code is presented. More complex applications will be presented in the near future.
