Aircraft engine anomaly detection based on odor, sound, and/or image

A full authority digital engine control comprising:

• a memory comprising computer readable instructions;
• and
• a processing device for executing the computer readable instructions, the computer readable instructions controlling the processing device to perform operations for aircraft engine anomaly detection based on a sound, the operations comprising:
• receiving from at least one sound detection sensor sound data indicative of the sound associated with an aircraft engine of an aircraft, at least one sound detection sensor configured to sample the aircraft engine according to a sound detection schedule;
• receiving odor from at least one odor detection sensor data indicative of the odor associated with an aircraft engine of an aircraft, the at least one odor detection sensor configured to sample an airflow through the aircraft engine according to an odor detection schedule;
• analyzing the sound data and the odor data to determine whether an anomaly associated with the aircraft has occurred;
• responsive to determining that an anomaly associated with the aircraft has occurred, implementing a corrective action based at least in part on the sound data;
• and
• updating the odor detection schedule based on the odor data, and the sound detection schedule based on the sound data.

A non-transitory computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations comprising:

• receiving from at least one odor detection sensor odor data indicative of an odor associated with an aircraft engine of an aircraft and receiving sound data indicative of a sound associated with the aircraft engine, the at least one odor detection sensor configured to sample an airflow through the aircraft engine according to a schedule;
• analyzing the odor data or the sound data to determine whether an anomaly associated with the aircraft has occurred;
• responsive to determining that an anomaly associated with the aircraft has occurred, receiving image data from an image sensor associated with aircraft;
• analyzing the image data to verify the anomaly;
• responsive to verifying the anomaly, implementing a corrective action based at least in part on the odor data or the sound data;
• and
• updating the schedule based on the odor data.
