Abstract

A system and method for controlling an aircraft engine is provided. The method includes a) producing first sensor data using a first sensor sensing a first parameter during operation of the aircraft engine on a flight mission; b) producing other sensor data using a plurality of second sensors sensing a plurality of other parameters, during operation of the aircraft engine; c) providing the first and other sensor data to a control unit during operation of the aircraft engine; d) storing the first and other sensor data during operation of the aircraft engine; e) using an artificial intelligence (AI) model that is trained using the stored first and other sensor data produced during operation of the aircraft engine, to produce one or more derived first parameter values; and f) selectively providing the one or more derived first parameter values to the control unit for use in controlling the aircraft engine.

2 . The method of claim 1 , wherein the one or more derived first parameter values are provided to the control unit upon a request by the control unit.

3 . The method of claim 2 , further comprising using the control unit to evaluate the first sensor data using the one or more derived first parameter values.

4 . The method of claim 3 , further comprising using the one or more derived first parameter values in the control of the aircraft engine.

5 . The method of claim 1 , wherein each respective second sensor of the plurality of second sensors is configured to sense a different parameter during operation of the aircraft engine on the flight mission.

6 . The method of claim 1 , wherein the AI model is used to produce the one or more derived first parameter values based on the stored other sensor data and the first sensor data produced during operation of the aircraft engine on the flight mission.

7 . The method of claim 1 , wherein the step of selectively providing the one or more derived first parameter values to the control unit includes continuously providing the one or more derived first parameter values to the control unit.

8 . The method of claim 7 , further comprising using the one or more derived first parameter values to evaluate the first sensor data during operation of the aircraft engine on the flight mission.
