Adaptive Thermal Management System

This technology employs a unique way to autonomously regulate the temperature of a structure or vessel.NASA seeks to license the Adaptive Thermal Management System (ATMS) for use in commercial applications. Developed at the John F. Kennedy Space Center, the ATMS provides a way to regulate heat transfer and enable thermal management between two opposing surfaces in either direction. The system has the capability to adapt to provide conductive or insulative functionality depending on environmental conditions or applied stimuli. The ATMS can be designed for use in manufacturing, storage vessels, fluid transfer, aerospace and building architectures, and many other applications to reduce unwanted heat transfer, lower energy usage, or maintain environments at a specific temperature. The ATMS is part of NASA’s technology transfer program, which seeks to promote the commercial use of NASA-developed technologies.

Method of Bonding Dissimilar Materials

Elastic adhesive overcomes the problems associated with large differences in thermal expansion coefficients. An image of the Materials International Space Station Experiment-5 (MISSE-5) samples prior to launch shows a golden thermal blanket with flexible material samples attached. NASA’s Goddard Space Flight Center has developed a new method for bonding dissimilar materials using an elastic adhesive to permit the bond to withstand variations in temperature and pressure. Specifically, NASA uses this method to provide a >98% specular finish on composite materials that is proven capable of withstanding ultraviolet solar radiation exposure in a vacuum and thermal cycling from –115 °C to +65 °C, as well as meeting outgassing requirement limits of 1%.
