ABSTRACT:
A method for estimating a trend in exhaust gas temperature in a turbine engine includes sampling exhaust gas temperature and a plurality of variables associated with the exhaust gas temperature over a set of observation times for a turbine engine to acquire exhaust gas temperature data. A trend in the exhaust gas temperature for the specific turbine engine is identified by removing the effect of the plurality of variables on the exhaust gas temperature data.
