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.
