PROPOSAL NUMBER: 98-1 07.02-4274

PROJECT TITLE: High-Temperature Optical Fiber Skin Friction Sensors for Aeropropulsion Flight Tests

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

Sensors that can withstand extremely high-temperature environments are required for 1) monitoring the performance of combustion engines, including aeropropulsion and power generation turbine systems, 2) process monitoring of new high-temperature, high-performance materials, such as metal- and ceramics-matrix composites and 3) evaluation of advanced aerospace structural materials at high temperatures. Currently, no reliable electrical or optical fiber-based sensor instrumentation is commercially available which can survive the high-temperature environment and provide continuous calibrated measurements. Optical fiber sensor technology is ideal for these applications due to the extremely high operating temperature of silica-based optical fiber waveguides (1650F/900C) and even higher operating temperature of sapphire-based optical waveguides (3600F/2000C). F&S, Inc. is developing optical fiber physical sensors for measurement of strain, temperature, pressure, acceleration, and skin which, in addition to their high-temperature capability, possess a number of practical advantages over traditional electrical-based instrumentation. F&S has been a world leader in the development of optical fiber sensor instrumentation for relatively low-temperature strain sensor instrumentation and proposes to add to their product line new sensors and systems that will withstand the rigorous demands of the high-temperature aeropropulsion environment.

POTENTIAL COMMERCIAL APPLICATIONS

In addition to addressing NASA's requirements for monitoring the high-temperature aeropropulsion environment, the proposed optical fiber sensors will compete within the multibillion dollar market for high-temperature sensor instrumentation for monitoring turbomachinery, power generation systems, advanced materials during high-temperature testing, and high temperature industrial process monitoring.
