  • Patent number: 10048168
    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.
