An improvement to the thin walled tank in the higher load region is developed by the addition of a prestressed jettisonable shell. Capability of the tank includes post-wrinkling strength in bending. Comparison is made with an efficiently stiffened tank, using for example a liquid hydrogen tank 10 ft in diameter. The results of the study show the total effective weight of the minimum gage pressurized tank with a prestressed jettisonable insulating shell to be less than one-half the weight of an insulated stiffened tank for a wide range of loading.
