摘要 |
An aircraft (300) includes first and second gas turbine engines (302, 304) having a first component (26, 30, 32, 34) and a second component (42, 46, 48, 50) that is redundant with the first component (26, 30, 32, 34), and an engine health monitoring system (EHMS) (310) coupled to the first and second gas turbine engines (302, 304). The EHMS (310) is configured to calculate a remaining useful life (RUL) (412, 414) of the first component (26, 30, 32, 34) and of the second component (42, 46, 48, 50), calculate a rate-of-life consumption of the first component (402) and of the second component (404), predict when failure (406) of the first component (26, 30, 32, 34) and failure (408) of the second component (42, 46, 48, 50) will occur based on the RUL of each (412, 414) and based on the respective rate-of-life consumption (402, 404) of each, and provide instructions for altering operation of the aircraft (300) that affects the RUL (416) of the first or second component (26, 30, 32, 34), (42, 46, 48, 50). |
