SMART Tape For Structural Health Monitoring of Rocket Engines, Phase II

Acellent Technologies, Inc. proposes to develop a SMART Tape system that can be used to perform rapid non-destructive evaluation in real time and provide long-term monitoring of pressure vessels in liquid rocket engines. Based on Acellent's existing SMART Layer technology, this innovative system combines a sensor network, dedicated signal processing and data analysis software to allow for real-time in-situ monitoring and long term tracking of structural integrity of pressure vessels (such as ducts, manifolds and combustion chambers) in rocket engines. Specifically, the proposed structural health monitoring system will have the following unique features: -Survive harsh environments and missions -Inspect inaccessible areas without disassembly -Ability to detect cracks and monitor crack growth in real-time -Prevent imminent and catastrophic failures in rocket engines The proposed innovation is important as it will address the need for safe as well as reliable advanced space exploration vehicle/propulsion systems. Acellent has been sub-contracted to develop the Structural Health Monitoring system as part of an Integrated System Health Management architecture development for Exploration Systems Research and Technology. The architecture will also support work that is currently on-going to define design solutions for NASA's proposed Crew Exploration Vehicle.

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.
