Abstract
The weight and Structural characteristics of the structural boxes of high aspect ratio wings are estimated by the application of high speed digital computers. The input to the problem consists of the basic wing geometry, the design loading conditions, and tables of allowable tension, compression, and shear stresses. By means of this data, the optimum arrangement of the structural material is calculated at a representative number of spanwise stations. The procedure is based on the assumptions of simple beam theory. The effects of multiple loads, the interaction of bending and shear stresses, and minimum gages are considered. The output of the computer provides the optimum material distribution, weight breakdown, and stiffness characteristics of the structural box. The effects of non optimum sheet thicknesses are also shown.
