Innovators at NASA’s Johnson Space Center have developed a software system with generalized capability to solve radiation-related aspects of thermal analysis problems. The Thermal Radiation Analyzer System (TRASYS) computes the total thermal radiation environment for a spacecraft in orbit by calculating internode radiation interchange data as well as incident and absorbed heat rate data originating from environmental radiant heat sources. A primary feature allows users to write their own driver programs to organize and direct the preprocessor and processor library routines in solving specific thermal radiation problems. TRASYS offers up to a 4,000 node problem size capability, with shadowing by intervening opaque or semi-transparent surfaces and a choice of diffuse, specular, or diffuse/specular radiant interchange solutions. The software may be released to U.S persons 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.
