Abstract

A system and method for determining performance of a turbine engine, and operation thereof. The system and method includes a plurality of sensors and one or more computing devices executing operations including acquiring a plurality of parameter sets each corresponding to a plurality of engine conditions in which each parameter set corresponding to each engine condition indicates a health condition at a plurality of locations at the engine; comparing the plurality of parameter sets to determine a health condition corresponding to a location at the engine; and generating a health condition prediction at the engine based on the compared parameters.

First claim

What is claimed is:

1. A system for determining performance of a turbine engine, the system comprising a plurality of sensors and one or more computing devices configured to perform operations, the operations comprising:
acquiring, via the plurality of sensors comprising a first sensor and a second sensor, a plurality of parameter sets each corresponding to a plurality of engine conditions, wherein acquiring the plurality of parameter sets comprises;
acquiring, via the first sensor, a first parameter set based on a first engine operating condition indicating a health condition at a first location of the engine;
acquiring, via the first sensor, a second parameter set based on a second engine operating condition indicating a health condition at a second location of the engine;
acquiring, via the second sensor, a third parameter set based on the first engine operating condition indicating a health condition at the second location; and
acquiring, via the second sensor, a fourth parameter set based on the second engine operating condition indicating a health condition at the first location;

comparing, via the computing device, the plurality of parameter sets to determine the respective health condition corresponding to the respective location at the engine; and
generating, via the computing device, a health condition prediction at the engine based on the compared plurality of parameter sets.

2. The system of claim 1 , the operations comprising:
comparing, via the computing device, the first parameter set, the second parameter set, the third parameter set, and the fourth parameter set to determine a health condition corresponding to respective locations at the engine.

3. The system of claim 2 , the operations comprising:
comparing the plurality of parameter sets to determine the health condition at the first location; and
comparing the plurality of parameter sets to determine the health condition at the second location.

4. The system of claim 2 , the operations comprising:
comparing the first parameter set and the fourth parameter set to determine the health condition corresponding to the first location.

5. The system of claim 2 , the operations comprising:
comparing the second parameter set and the third parameter set to determine the health condition corresponding to the second location.

6. The system of claim 1 , the operations comprising:
determining, via the computing device, one or more locations of a health deterioration contributor via the compared parameter sets.

7. The system of claim 1 , the operations comprising:
generating, via the computing device, a signal to an operator of the engine indicating an action item for the operator to perform.

8. The system of claim 7 , the operations comprising:
transmitting, via the computing device, the signal indicating an engine manoeuver.

9. The system of claim 7 , the operations comprising:
transmitting, via the computing device, the signal indicating a maintenance action.

10. The system of claim 7 , the operations comprising:
transmitting, via the computing device, the signal indicating an operating limit.

11. The system of claim 1 , the operations comprising:
operating the engine at a plurality of engine operating conditions.

12. A method for operating an engine based on a health deterioration condition, the method comprising:
acquiring a plurality of parameter sets each corresponding to a plurality of engine conditions, wherein acquiring the plurality of parameter sets comprises;
acquiring, via a first sensor, a first parameter set based on a first engine operating condition indicating a health condition at a first location of the engine;
acquiring, via the first sensor, a second parameter set based on a second engine operating condition indicating a health condition at a second location of the engine;
acquiring, via a second sensor, a third parameter set based on the first engine operating condition indicating a health condition at the second location; and
acquiring, via the second sensor, a fourth parameter set based on the second engine operating condition indicating a health condition at the first location;

comparing the plurality of parameter sets to determine the respective health condition corresponding to the respective location at the engine; and
generating a health condition prediction at the engine based on the compared plurality of parameter sets.

13. The method of claim 12 , the method further comprising:
determining one or more locations of a health deterioration contributor via the compared parameter sets.

14. The method of claim 12 , the method further comprising:
generating a signal to an operator of the engine indicating an action item for a user to perform.

15. The method of claim 14 , the method further comprising:
transmitting the signal indicating an engine manoeuver.

16. The method of claim 14 , the method further comprising:
transmitting the signal indicating a maintenance action.

17. The method of claim 14 , the method further comprising:
transmitting the signal indicating an operating limit.

18. The method of claim 12 , the method comprising:
operating the engine at a plurality of engine operating conditions.
