DESIGN CRITERIA AND ANALYSES FOR THINWALLED PRESSURIZED VESSELS AND INTERSTAGE STRUCTURES
Abstract
This report considers the problem of varied philosophies of design criteria in the missiles and spacecraft industry in relation to preliminary design work. The report offers a set of design ground-rules consistent with safety factors and materials allowable as an effective approach not only for structural preliminary design but also for general application by the structural design analyst. Specific uses involving design of thin-walled pressurized vessels and interstage structures are presented. Criteria with respect to factors of safety and use of buckling probability curves are included for structures in which a buckling type of failure under axial compression predominates. Formulae for determining gages for tanks and interstages are given and a set of graphs is provided which permits rapid calculation of the weights of tanks. The report also contains a graph which shows the weight penalty incurred for tanks which deviate from a spherical shape, and there is a graph presenting the volume of a tank as a function of the diameter. Critical axial compressive stress coefficients for different philosophies of structural design are graphically illustrated and curves for allowable load versus thickness based on these philosophies are presented.
