Technical Abstract (Limit 2000 characters, approximately 200 words)

Propulsion systems require rigorous and highly instrumented testing to enable a comprehensive analysis of performance and to minimize risks associated with space flight. Current testing instrumentation methods can be replaced with embedded sensor systems that are used for monitoring remote, hazardous, or inaccessible locations, while reducing cabling and power consumption. The additional information from the embedded sensor system will enable improved analysis techniques that will accelerate propulsion system developments. Luna proposes to develop a multi-function, drop in, sensor capable of simultaneously measuring temperature, heat flux, strain, and pressure in metal piping using embedded distributed fiber optic sensors. During Phase II, Luna will develop the prototype sensor for rocket engine test facility applications. The sensor system will be highly flexible for a variety of extreme conditions (e.g. cryogenic) intended for remote or inaccessible locations. This approach will minimize the cabling associated with multiple independent sensors such as thermocouples and pressure transducers, as well as increase safety benefits inherent in utilizing intrinsically safe fiber optic sensors in the presence of fuel systems.

Potential NASA Applications (Limit 1500 characters, approximately 150 words)

Distributed multi-parameter sensing can benefit existing and future rocket engine and test bed systems to monitor remote or inaccessible piping locations. Distributed sensing in turbojet engine applications in bypass piping, fuel delivery, and turbine coolant channel systems can be used for engine health monitoring. Satellite heat pipe sensing can provide data for cooling and power management. Computational models can leverage high fidelity distributed data for validation purposes.

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)

Automotive and commercial aircraft industry can use the sensors in critical high temperature components to detect the onset of hardware failure. Distributed sensing in high pressure and temperature fluid systems in nuclear power, oil and gas, and industrial applications can be used to optimize processes and structural health in remote or inaccessible locations.
