Abstract
A health monitoring system including an array of microphones, a data collection system, and analytic software used to detect health status, pending malfunctions, or faults of several disparate, engine subsystems. The system can be used to monitor health of the main engines, the engine nacelles, and auxiliary power units (APU) on the aircraft.
Claims22
A system, comprising:
- one or more acoustic sensors outputting signals in response to acoustic waves transmitted to the one or more acoustic sensors from a plurality of distinct engine subsystems of an engine;
- when the distinct engine subsystems are acoustically coupled to the acoustic sensors;
- and
- wherein the signals comprise information used to monitor a health status of each of the distinct engine subsystems.
1 more element
A system, comprising:
- one or more acoustic sensors outputting signals in response to acoustic waves transmitted from one or more engine components;
- a computer connected to the acoustic sensors, wherein:
- the computer analyzes the signals using a computer-implemented machine learning model, and
- the computer-implemented machine learning model determines the health status of the engine components.
1 more element
A computer-implemented method, comprising:
- monitoring health of an engine or engine subsystem, including:
- receiving signals in response to acoustic waves transmitted from the engine or the engine subsystem;
- providing a computer-implemented machine learning model;
- analyzing the signals using the computer-implemented machine learning model so as to determine a health status of the engine or the engine subsystem.
