Book Description
Summary: An investigation was made by lifting-surface theory of a thin elliptic wing of aspect ratio 6 in a steady roll by means of the electromagnetic-analogy method. From the results, aspect-ratio corrections for the damping in roll and aileron hinge moments for a wing in steady roll were obtained that are considerably more accurate than those given by lifting-line theory. First-order effects of compressibility were included in the computations. The results obtained by lifting-surface theory indicate that the damping in roll for a wing of aspect ratio 6 is 13 percent less than that given by lifting-line theory and 5 percent less than that given by lifting-line theory with the edge-velocity correction derived by Robert T. Jones applied. The results are extended to wings of other aspect ratios.

Book Description
Results are present for part of a test program on 24S-T aluminum-alloy flat compression panels with hat-section stiffeners. The results show the effect of the relative dimensions of a panel on the buckling stress and average stress at maximum load. Comparative envelope curves are presented to provide some indication of the relative structural efficiencies of hat- and Z-stiffened panels having a ratio of stiffener thicknews to skin thickness of one.
