| Abstract: |
| The wind-gust response analysis of a composite wing in Turbulent flow was performed using the PEM (pseudo excitation method) and CFD technique,which were implemented based on the self-developed structural analysis program DDJ-W.The use of the PEM improves the computational efficiency considerably and the selection of CFD technique can obtain the aerodynamic parameters accurately.The power spectral responses and variances of the wing were computed using the Dryden atmospheric turbulence spectrum.The computation process shows that the suggested method is accurate and highly-efficient for the analysis of wind-gust responses of composite wings. |
