FOD detection/diagnosis

N&R developed a real-time fault detection/diagnostic code (FODID) that utilizes a weighted least-squares methodology to identify faults such as foreign object damage (FOD) and determine which components are damaged and how severely. This tool performs both a gas path analysis and a structural vibration analysis, and then fuses the resulting data using fuzzy logic to provide a more confident solution than relying on either detection methodology alone.
