Abstract : Two structural concepts have been identified and investigated to obtain a better insight into problems associated with structures for hydrogen-fueled hypersonic airplanes. One of these is the multiwall sandwich concept which combines the evacuated thermal protection, tankage, and load-carrying functions into a single component. The other concept is based on the use of an unsealed structure that does not require vacuum sealing, but rather utilizes carbon dioxide gas to purge the insulation space between the structure and tanks. A brief look at some characteristics of these two concepts and some analytical and experimental results related to the concepts are presented.
