Structural Analysis and Influence Coefficients for Delta Wings

A method is presented for determining the stresses and de~ formations in delta wings of multispar construction having chord wise ribs and thin cover sheets. The spars need not be parallel, and the cover sheets can have large cutouts. The individual spars may be clamped, simply supported, or free at the root. The method is based on the interaction between the bending stiffnesses of the spars and ribs with effective cover sheet and the torsional stiffness of the cover sheet. The method is well suited to the use of high-speed computing machines.
