Foreign object debris trending concept and design

A system for foreign object debris (FOD) detection in a gas turbine engine, comprising:

• a controller in electronic communication with a memory, the controller configured to:
• receive a first time-series data from the memory, wherein the first time-series data is measured by a first debris monitoring sensor coupled to the gas turbine engine;
• receive a second time-series data from the memory, wherein the second time-series data is measured by a second debris monitoring sensor coupled to the gas turbine engine, wherein the first debris monitoring sensor monitors a compressor section of the gas turbine engine and the second debris monitoring sensor monitors a turbine section of the gas turbine engine, the compressor section drives air along a core flow-path for compression and communication into a combustor section and subsequently expansion through the turbine section;
• generate a first feature data based upon a first calculation using the first time-series data;
• generate a second feature data based upon a second calculation selectively using at least one of the first time-series data or the second time-series data, wherein the first calculation is different from the second calculation in response to the second calculation being performed using the first time-series data;
• detect at least one anomaly in the first feature data;
• detect at least one other anomaly in the second feature data;
• determine an occurrence of a FOD event based upon the at least one anomaly and the least one other anomaly, wherein the at least one anomaly corresponds to a first FOD event in the compressor section of the gas turbine engine and the at least one other anomaly corresponds to a second FOD event in the turbine section of the gas turbine engine;
• and
• report a FOD damage health report (HR) in response to the calculated anomaly indicating the occurrence of a FOD event.

An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon for detecting foreign object debris in a gas turbine engine that, in response to execution by a controller, cause the controller to perform operations comprising:

• receiving, by the controller, a first time-series data from the memory, wherein the first time-series data is measured by a first debris monitoring sensor signal;
• receiving, by the controller, a second time-series data from the memory, wherein the second time-series data is measured by a second debris monitoring sensor coupled to the gas turbine engine, wherein the first debris monitoring sensor monitors a compressor section of the gas turbine engine and the second debris monitoring sensor monitors a turbine section of the gas turbine engine, the compressor section drives air along a core flow-path for compression and communication into a combustor section and subsequently expansion through the turbine section;
• generating, by the controller, a first feature data based upon a first calculation using the first time-series data;
• generating, by the controller, a second feature data based upon a second calculation selectively using at least one of the first time-series data or the second time-series data, wherein the first calculation is different from the second calculation in response to the second calculation being performed using the first time-series data;
• detecting, by the controller, at least one anomaly in the first feature data;
• detecting, by the controller, at least one other anomaly in the second feature data;
• determining, by the controller, an occurrence of a FOD event based upon the at least one anomaly and the at least one other anomaly, wherein the at least one anomaly corresponds to a first FOD event in the compressor section of the gas turbine engine and the at least one other anomaly corresponds to a second FOD event in the turbine section of the gas turbine engine;
• and
• reporting, by the controller, a FOD damage health report (HR) in response to the detected anomaly indicating the occurrence of a FOD event.
