Abstract
In this paper,a numerical simulation technology which combined Computational Fluid Dynamics(CFD) method with Computational Structure Dynamic(CSD) is developed.A numerical simulation study of static aero-elastic for three-dimensional aircraft wing is carried out.To analysis aerodynamic performance,three-dimensional Euler equations solver based on Cartesian grid are used and structure static equilibrium equations are coupled for static aero-elastic numerical simulation.Mode of exchange data in the CFD/CSD coupled computation is designed.In this paper,M6 wing as an example,the wing static aero-elastic numerical simulation is carried out.The computed result indicates method of static aero-elastic numerical simulation on the three-dimensional aircraft wing is reasonable and feasible.This method provides a base for wing structure optimization design and aerodynamic shape optimization design considering structure elasticity deformation.
