SYSTEM AND METHOD FOR OPTIMIZING COMPONENT LIFE IN A POWER SYSTEM
First Claim
1. An aircraft, comprising:
- first and second gas turbine engines having a first component and a second component that is redundant with the first component; and
an engine health monitoring system (EHMS) coupled to the first and second gas turbine engines, the EHMS configured to;
calculate a remaining useful life (RUL) of the first component and of the second component;
calculate a rate-of-life consumption of the first component and of the second component;
predict when failure of the first component and failure of the second component will occur based on the RUL of each and based on the respective rate-of-life consumption of each; and
provide instructions for altering operation of the aircraft that affects the RUL of the first or second component.

Abstract
An aircraft includes first and second gas turbine engines having a first component and a second component that is redundant with the first component, and an engine health monitoring system (EHMS) coupled to the first and second gas turbine engines. The EHMS is configured to calculate a remaining useful life (RUL) of the first component and of the second component, calculate a rate-of-life consumption of the first component and of the second component, predict when failure of the first component and failure of the second component will occur based on the RUL of each and based on the respective rate-of-life consumption of each, and provide instructions for altering operation of the aircraft that affects the RUL of the first or second component.

17. A non-transitory computer-readable medium tangibly embodying computer-executable instructions comprising instructions to:
-
calculate a remaining useful life (RUL) of a first component and of a second component of an aircraft that is redundant with the first component; calculate a rate-of-life consumption of the first component and of the second component; predict when failure of the first component and failure of the second component will occur based on the RUL of each and based on the respective rate-of-life consumption of each; and provide instructions for altering operation of the aircraft that affects the RUL of at least one of the first and second components. - View Dependent Claims (18, 19, 20)
