Abstract

High-fidelity computational aeroelasticity based on CFD/CSD coupling method can capture the nonlinear effects in both aerodynamic and structural aspects. In this paper, geometrically nonlinear static aeroelastic problems of very flexible wings are solved based on CFD/CSD interaction accelerated by panel method. The acceleration of convergence is realized by introducing aerodynamic stiffness matrix based on panel method to reduce the computational cost of CFD. Considering the large deformation case, aerodynamic loads are applied as follower forces which change in direction along with the structural deflection. Geometrically nonlinear finite element method is employed for structural analysis. The numerical research of a high aspect-ratio wing is provided and the results are verified by the wind tunnel test data. Compared with the conventional staggered strategy, the proposed accelerated algorithm can improve the calculation efficiency under the same accuracy requirements.
