Completed TRL 3 (started at 2, targeting 3)
Advancements in design and development of evaluation methodologies were made in transient thermal testing. Development of multifunctional and thermally switchable systems to address reduced mass and components, and tailored for both structural and transient thermal applications. Active, passive, and novel combinations of the two functional approaches are being developed along two lines of research investigation: switchable systems and transient heat spreading. The approach was to build in thermal functionality to structural elements to lay the foundation for a revolution in the way high energy space systems are designed.
The research team took a fully collaborative approach with NASA, the University of Central Florida, Embry Riddle Aeronautical University, and a global research commercial partner on the development and application of novel materials. Information gained in this study will be leveraged to propose future funding to advance the technology readiness level (TRL) for extreme conditions applications.
The three materials research tasks and associated partners that were explored during this project are summarized as follows:
The benefits to NASA include the following: increased controllability, reduction in energy and power usage, improved thermal management controls, reduced turnaround time, increased system availability, a potential for 50% reduction in cryogenic loading time and reduction in commodity boil-off and helium usage.
This concept is expected to translate to game changing approaches for NASA’s exploration and habitations missions, significant reduction in life cycle costs, decreased energy and power consumption, while increasing safety and reliability. The topic of transient thermal management present a wide range of applications and revolutionary approaches to the architectures, designs, and operations of high energy space systems, life support equipment, and human habitats.
Advancement in this technology, such as mass-efficient storage and transfer of cryogens in space, will aid in meeting the unique thermal requirements of the aerospace industry. Benefits to industries, such as cryogenics, satellites, and commercial aircraft could be realized with this technology.
Benefits to other government agencies are also anticipated to help meet standards set by Standard Test Methods and Materials Practices (ASTM International).
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
