Towards an Energetic Modeling of Rotorcraft Using Bond-Graphs
Communication avec acte
The paper presents an energetic method of helicopters dynamics analysis to study the air resonance (AR) phenomena. First, a brief state of art of AR phenomena is presented and a simple energetic explanation is given. Then part of the state of art is devoted to the Bond Graph (BG) and Multi-Bond Graphs (MBG) modeling method showing several advantages of the tool and few examples of MBG researches applications. This work proposes a macroscopic energetic description of a helicopter through the Word Bond Graph representation. The MBG is then used for Rotor/fuselage structure modeling in order to study the AR phenomena instability. The MBG model results are presented and show the potential of the MBG method to predict such a complex phenomenon.

Understanding pilot biodynamical feedthrough coupling in helicopter adverse roll axis instability via lateral cyclic feedback control Article dans une revue avec comité de lectureTOD, Georges; PAVEL, Marilena; BARRE, Pierre-Jean; GOMAND, Julien; MALBURET, François (Elsevier, 2016)The paper reassesses the mechanism of biodynamical feedthrough coupling to helicopter body motion in lateral-roll helicopter tasks. An analytical bio-aeroelastic pilot–vehicle model is first developed and tested for various ...
