SYSTEM AND METHOD FOR TRENDING EXHAUST GAS TEMPERATURE IN A TURBINE ENGINE

摘要

A method for estimating a trend in exhaust gas temperature in a turbine engi ne (14) 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 (14) to acquire exhaust gas temperature data. A trend in the exhaust gas temperature for the specific turbine engine (14) is identified by removing the effect of the plurality of variables on the exhaust gas temperature data.
