Thin Aerogel as a Spacer in Multi-Layer Insulation for Cryogenic Space Applications
Project Description
Long duration storage of large quantities of cryogenic fluids for propulsion, power, and life-support is an essential requirement for long-term missions into space. The behavior of active and passive cryogenic fluid management (CFM) is paramount to the reliability of a spaceship and cryotank storage. Therefore, efficient and reliable insulation materials are key to the success of space missions. Aspen Aerogels proposes to develop a Multi-Layer Aerogel Insulation (MLAI) system to meet NASA's CFM needs. Aerogel has been demonstrated to be more durable and reliable than MLI, at a lower weight and reduced cost with comparable thermal performance. During this program, Aspen Aerogels will validate the key process step for a next generation aerogel manufacturing technology to enable the fabrication the proposed aerogel material. This new process is also expected to enable cost reduction of aerogel materials in general, a requirement to penetrate larger commercial thermal insulation markets. Development of the proposed MLAI system will provide NASA with a long-term CFM solution for space applications.

Anticipated Benefits
Low weight, ease of installation and overall mechanical and thermal performance of aerogels as a spacer material will serve as a durable and more reliable replacement for NASA's traditionally used multi-layer insulation (MLI). Durability improvements will reduce maintenance costs and extend the period of cryogen storage and the life expectancy of the insulation system. In addition to spacecraft and other cryogen storage, applications including EVA suits, gloves, and footwear could also benefit from the thin and low density aerogel technology. The proposed insulation material will also find use in terrestrial applications, such as improved and durable insulation material for cryogenic fluid storage and transfer pipelines in preparation for launch.
Successful development of a multi-layer aerogel insulation system will be immediately useful for a wide variety of cryogenic applications such as cryogenic storage tanks and transfer lines for LNG, LN2, etc. Thin aerogel would also be highly applicable to the very large apparel insulation market. Additionally, reducing aerogel cost through this process will allow much broader penetration into existing insulation markets, including building and construction. More »
