About this technology
Overview
NASA Kennedy Space Center seeks partners interested in a practical method for measuring thermal performance of materials at below-ambient temperatures or subjected to a large temperature difference. The technology uses liquid nitrogen as a direct heat energy meter and is applicable to testing at a wide range of temperatures from 373 K down to 77 K and under an ambient pressure environment. The Macroflash follows the guidelines of the newly established technical standard ASTM C1774 (Annex A4) and provides a cost-effective, field-representative methodology to test any material for below-ambient temperature applications. From engineered systems to research testing to quality control in manufacturing, the technology provides utility for the fields of energy, transportation, construction, and environment.
