04.2 - Structural Analysis and Design, Structural Dynamics, AeroelasticityAEROELASTIC WIND TUNNEL EXPERIMENT OF A HIGH-ASPECT-RATIO WING MODEL AGAINST GEOMETRICAL NON-LINEARITYW. Qian¹, Y. Bai¹, H. Zeng, Shenyang Aircraft Design Institute, China; R. Yang¹; ¹Dalian University of Technology, China This work wanted to study flutter characteristics of high-aspect-ratio wing with large deformation which can consider geometrical non-linearity effects. Both wind tunnel tests and numerical method were employed. Through the experimental phenomenon, a series of new flutter characteristics were observed. Complex aeroelastic patterns related to geometrical non-linearity can be analyzed. |
