Scott, R.F. Institution National Research Council Canada, National Aeronautical Establishment, Structures Laboratory Date 1964-12-31 Abstract For several models of low- aspect ratio wings of constant chord, with and without sweep, matrices of influence coefficients were available from earlier calculatjons and test data. These data have been utilized to calculate the first five natural frequencies and the corresponding modes of the cantilevered wing models, making various assumptions in regard to mass distribution. The extensive results are presented in graphical form. Comparisons are maoe with theoretical and experimental results for cantilever beams and for uniform plates of similar shapes .
