【Abstract】 A scaling-down wing-box model was designed on the basis of structural similarity and manufactured by means of integral-forming of composites for modal analysis and test, in which the similarity of structural dynamics and loading transfer were realized at the same time. The modal analysis and test was done and the results were in good agreement. This model lays a foundation of the flutter test of high-speed wing in low-speed wind tunnel.更多还原
