Gas turbine engine and test cell real-time diagnostic fault detection and corrective action system and method
First Claim
1. A real-time diagnostic and fault detection method for a gas turbine engine under test in a test cell, the method comprising:
- supplying, to a processing system, sensor data from instrumentation coupled to the gas turbine engine that is under test in the test cell;
processing the sensor data, using a physics-based component level aero-thermal model of the gas turbine engine that is implemented in the processing system, to calculate a plurality of engine parameters at a plurality of different, non-instrumented locations within the gas turbine engine;
processing, in the processing system, the plurality of engine parameters to detect when a fault exists within the gas turbine engine; and
when a fault does exist within the gas turbine engine;
rendering, on a display device, an image that indicates at least a mostly likely cause for the fault,generating one or more corrective actions that can be taken to correct the fault, andat least selectively rendering, on the display device, the one or more corrective actions.

Abstract
A real-time diagnostic and fault detection system and method for a gas turbine engine under test in a test cell is disclosed. Sensor data from instrumentation coupled to the gas turbine engine are processed, using a physics-based component level aero-thermal model, to calculate a plurality of engine parameters at a plurality of non-instrumented locations within the gas turbine engine. The plurality of engine parameters are processed to detect when a fault exists and, when a fault does exist, an image is rendered that indicates at least a mostly likely cause for the fault and one or more corrective actions that can be taken to correct the fault. The model is also used to generate projections of engine performance at one or more selected test conditions, and to prognosticate, based on the projections, as to whether the gas turbine engine will actually pass at the one or more selected test conditions.
