Abstract : This report contains the results of an investigation which was performed concerning the feasibility of various structural concepts for future space vehicles such as the HL-10 configuration. Various combinations of ablator and sub-structure were analyzed to survive the environments of ascent, space flight, and reentry at velocities between 26,000 and 36,500 feet per second. The concepts were applied to representative locations on the vehicle and evaluated in terms of thermal and structural performance; weight, which is a measure of efficiency of performance; ease of fabrication; reusability and/or refurbishability; and fabrication and assembly costs. To aid in the evaluation, comparisons were made between double and single wall concepts. The merits of integrated wall construction were examined in conjunction with the double wall concept. The term 'integrated wall' as applied herein refers to reliance on the load-carrying ability of the ablator material in the structural design of an ablator-substructure composite shell.
