Innovators at NASA’s Johnson Space Center (JSC) have developed a software program that determines the minimum weight of an n-layer thermal protection system (TPS) material to meet mission and spacecraft parameters and constraints. The Automated Engineering Scientific Optimization Program – Standard Ablation Program (AESOP-STAB) was first developed at JSC in the early 1970s as part of the Gemini and Apollo programs. It has been modified recently to be more generic and has applicability to other heat shield protection ablators with associated differences in material composition and chemistry. AESOP-STAB can calculate a required TPS thickness for a specific temperature constraint or determine temperatures and recession for a specific design thickness. This software may be released for U.S. Government purposes only.
This technology is being made available through JSC’s Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
