Integrated health management approach to propulsion control system protection limiting
First Claim
1. An engine system comprising:
- a controller system that controls demand on a first component of an engine, wherein the controller system includes at least one controller and is configured to;
access a first set of prognostic data about the first component, wherein the first set of prognostic data includes a remaining lifespan approximation of the first component operating at a present operating condition;
identify a temporal length of an engine procedure operating at the present operating condition;
decrease a maximum hard current limit of the first component to increase the remaining lifespan approximation of the first component beyond the temporal length; and
implement the current limit constant associated with the first component so that the first component does not fault during engine operation.

Abstract
A real-time engine management system having a controller system configured to control demand on a first component of an engine. The controller system is also configured to access a first set of prognostic data about the first component, where the first set of prognostic data includes a remaining lifespan approximation of the first component operating at a present operating condition. The controller system is also configured to identify a temporal length of an engine procedure operating at the present operating condition, alter a current limit constant associated with the first component to increase the remaining lifespan approximation of the first component beyond the temporal length, and implement the current limit constant associated with the first component so that the first component does not fault during the engine procedure.

8. A system comprising:
-
an engine having a plurality of components each respectively configured to carry out a plurality of engine tasks; a controller that manipulates operating conditions of each the plurality of components; and a computer with a processor that; identifies a first component predicted to fail during an active engine operation from the plurality of components; determines at least one new operating condition for the first component such that when implemented by the controller the first component will no longer be predicted to fail, where the at least one new operating condition includes a new maximum hard limit constant that is lower than a present maximum hard current limit; and causes the controller to implement the at least one new operating condition so that the first component is no longer predicted to fail during the active operation. - View Dependent Claims (9, 10, 11, 12)

13. A method comprising:
-
identifying, by way of a processor, a first engine component that is predicted to fail during an active on-station operation, wherein identifying the first engine component occurs during the active on-station procedure; decreasing, by way of the processor, a first maximum hard current limit constant during the active on-station procedure to provide a new first engine component limit protection to the first engine component, wherein decreasing the first maximum hard current limit constant alters the active on-station procedure to an altered active on-station procedure; and determining, by way of the processor, that the first engine component working under the new first engine component limit protection is predicted to successfully perform during the altered active on-station procedure. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
