Shape Memory Alloys for Transient Thermal Applications
KSC and Florida Space Institute/University of Central Florida
Partnership
• The goal of this project is to bring together novel, unique materials
and transient thermal systems. The project will identify novel
materials and utilize specialty or custom made shape memory alloys
that can adapt under transient thermal management applications,
including cryogenic applications. All within a single architecture
