Abstract

The inherent electromagnetic interference (EMI) immunity and other benefits of fiber optic technology provide numerous opportunities for it's use in aerospace applications. Rosemount Aerospace Inc. has focused significant resources on the advancement of fiber optic sensors for use in both aircraft and engine environments. These efforts include the development of a fiber optic temperature sensor based on the fluorescent time rate of decay (TRD) principle. General Electric Aircraft Engines recently completed an evaluation of a Rosemount Aerospace TRD system. The test consisted of 229 hours of testing on the inlet screen of a General Electric F404 Engine. The objective of the test was to monitor the performance of the optical sensor assembly on an aircraft engine and to compare the optical signal with the output of the corresponding electrical sensor. This paper will review the TRIJ system design and GE engine test results. Key Words: TRD, optical temperature sensor, engine inlet sensor, fluorescence, time rate of decay, F404
