Abstract
Development of sensors for fly-by-light applications has focused more on development of airframe sensors than engine sensors. In this paper, we report on a limited suite of fiber optic sensors for on-engine sensing applications. The sensors are multimode and sense the parameters: engine speed, fuel presence and electrical current. Principles of sensor operation will be given and results of sensor testing on a Pratt & Whitney gas turbine engine will be provided. In addition, possible multiplexing options for these sensors will be discussed.
