For many years, programs have focused on single optical fiber sensors for each measurement required on an engine. Sensor systems therefore required signal processing for each of these individual sensors. While this approach provided the best individual sensor for each measurement, the system cost and complexity suffered. BFGoodrich has begun a new program focused on developing an optical fiber engine sensor suite based on one single sensing mechanism to monitor the majority of the measurements on an engine. The sensors will be optically multiplexed to a single signal processing unit thereby reducing cost, weight and size for the overall system. This program is a joint effort among three BFGoodrich divisions: Aircraft Sensors Division (Rosemount Aerospace), Aircraft Integrated Systems Division and Engine Electrical Systems Division. The program is described and results to date on choosing and developing the single sensing mechanism are presented.
