The Flight Loads Laboratory (FLL) at the NASA Dryden Flight Research Center (DFRC) is attempting to acquire high-temperature dynamic strain measurements by using optical-strain sensors as a secondary experiment on the C-17 (The Boeing Company, Chicago, Illinois) engine '17th Stage Bleed-Air Duct Redesign Verification' tests. The Extrinsic Fabry-Perot Interferometer (EFPI) optical sensors have been used successfully during ground tests to measure static strains to temperatures as high as 1850 F, but no measurement attempt has been made in a combined high-temperature/vibration environment. In addition to optical strain measurements, valuable application experience and data will be generated from thermal-sprayed, free-filament, wire resistive strain gages in this hostile environment.
