Nervure or "deformable rib" framework intended to allow alterations to an airfoil surface during flight. Could be construed as a wing warping technology.
This patent is succeeded by Patent GB-1911-19550 which contains much of the same material, as well as some more specific details of situations in which the warping might be implemented. Based on the details of content, these all descend from Patent BE-1909-218585.
