High-Speed Thermal Characterization of Cryogenic Flows, Phase I

The John C. Stennis Space Center's primary mission is testing rocket propulsion systems and components for the Space Shuttle and for future generations of space vehicles. Research to develop new instrumentation technologies and techniques for test facility monitoring and control during propulsion testing includes the need for instrumentation to improve reliability and performance of ground test facilities. Current sensors can not survive the harsh conditions (high pressures and high flow rates) that are required for ground based rocket propulsion systems testing. Luna Innovations proposes to develop a high-speed, cryogenic fiber optic temperature sensor housed in a ruggedized, aerodynamic probe to increase sensing capabilities for ground-based rocket testing. Luna will be teaming with the Aerospace Department at a partnering university to develop a materials-compatible housing designed for survivability in high flow and high pressure cryogenic conditions. Computational fluid dynamics (CFD) modeling will be conducted to optimize the aerodynamic design for frequency response and ruggedization of the sensor and housing. Special attention will be given to designing smart features into the sensor, such as self-diagnostics to monitor sensor health, and on-board storage of calibration data.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
