Experimental Flutter Results for Corrugation-Stiffened and Unstiffened Panels
Abstract
The results of a flutter investigation of 19 corrugation-stiffened and 6 flat unstiffened rectangular panels are presented. These results show that boundary conditions in the cross-stream direction have an important effect on panel flutter. It is also shown that the flutter of square orthotropic panels is not easily predicted, and that, at present, a flutter envelope appears to be the best available means for the prediction of the flutter boundaries for such pans. In addition, a method for analyzing the stiffness of corrugation-stiffened skin panels is presented. A 'preflutter' solution is shown to approximate accurately the exact solution for simply supported panels with in-plane tension loads, but both solutions differ considerably from the experimental results.
