Optimum Design of Pressure Stabilized Beams

Abstract

The minimum weight design problem for pressure-stabilized beams is formulated and solved in order to provide the designer some guidance in the use of the design analysis capability developed and reported previously. The weight is minimized subject to four inequality constraints to give the inflation pressure, cross-section radius and fabric density corresponding to the minimum weight. It is shown that high pressures, small radii, and low fabric density give minimum weight. In addition, it is found that high fabric strength and low fabric stiffness per unit weight should be used for minimizing the weight.
