Thermal and Pressure-Induced Strains in Internal Cryogenic Insulations
The exacting requirements of aerospace science for functional systems with high reliability and minimum weight and volume displacements have generated within industrial technology a search for new materials and their judicious application to systems designed to operate efficiently within wide ranges of temperature and pressure. One such area of effort is involved with the containment of cryogens. The currently planned programs utilizing large, liquid-fueled space boosters demand cryogenic insulation systems exhibiting optimum thermal and structural compatibility. Disregarding the relative merits of internal and external insulation systems, there will be evidence of thermal and mechanical stresses in each of these systems, primarily introduced under the influences of the contained cryogenic fluid and the aerodynamic forces and inertia loads.
