RBF Morph will be present at the 9th European Fluid Mechanics Conference EFMC9 that will be held on 9 -13 September 2012 at Main lecture hall of the University of Rome “Tor Vergata”, with two presentations: A review of mesh morphing applications using RBF Morph (12th 15:30 session IND2 room P12) by M.E. Biancolini and Fluid Structure Interaction with RBF Morph: Aeroelastic Analysis of a Full Aircraft Model and Comparison with Experimental Data (10th 11:45 session FS1 room T4) by M.E. Biancolini, U. Cella, M. Mancini.
Fluid Structure Interaction with RBF Morph: Aeroelastic Analysis of a Full Aircraft Model and Comparison with Experimental Data
A method for fluid structure interaction numerical modelling is herein presented.
The volume mesh used for CFD calculations is parameterized according to FEM computed structural modal shapes thanks to a morpher.
Modal loads are directly integrated over the CFD mesh and allow to calculate actual values of modal coordinates both for static and transient problems.
Such parametric CFD model with modes embedded becomes flexible, i.e. capable to deform its shape under structural loads without the need to further interact with structural FEM model.
Proposed method is demonstrated with an industrial application, the aeroelastic analysis of a Full aircraft model, using the following commercial software: NX Nastran and ANSYS Fluent® coupled with the mesh morphing add-on RBF MorphTM.
The results of the analysis were validated against Piaggio Aero Industries property high-speed experimental data, obtained during a test campaign performed in the ONERAS2MA transonic wind tunnel.
