Method and systems for controlling gas turbine engine temperature
First Claim
1. An engine controller system comprising:
- an engine model programmed to receive engine operating condition values from a plurality of sensors positioned on an engine, said engine model programmed to determine a plurality of engine operating parameter values from the received engine operating condition values that correspond to a location on the engine that is different from the sensor positions, wherein the determined operating parameter values represent a gas-path temperature within the engine; and
a processor configured to;
compare the determined operating parameter values to a predetermined allowable range for the operating parameter; and
at least one of control the operation of the engine to facilitate at least one of returning the determined operating parameter to the predetermined allowable range and maintaining the determined operating parameter within the predetermined allowable range, and output the determined operating parameter values to a user.

Abstract
A method and systems for controlling an engine are provided. The system includes an engine model programmed to receive engine operating condition values from a plurality of sensors on an engine. The engine model is programmed to determine a plurality of engine operating parameter values. The system also includes a processor configured to compare the operating parameter values to a predetermined allowable range for the operating parameter and control the operation of the engine to facilitate returning the determined operating parameter to the allowable range or maintaining the determined operating parameter within the allowable range, output the determined operating parameter values to a user, and/or generate maintenance requests based on the comparison.

5. A method of controlling the operation of an engine, said method comprising:
-
receiving data from a plurality of sensors associated with corresponding sensed locations on the engine; applying the received data to a model stored in a computer, the computer model configured to simulate an operation of the engine; determining an operating parameter of the engine based on an output from the computer model, wherein the determined operating parameter corresponds to a location on the engine that is different from the sensed locations, wherein the determined operating parameter values represent a gas-path temperature within the engine; comparing the determined operating parameter to a predetermined allowable range for the operating parameter; and at least one of controlling the operation of the engine to facilitate at least one of returning the determined operating parameter to the predetermined allowable range and maintaining the determined operating parameter within the predetermined allowable range, outputting the determined operating parameter values to a user. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
