FIELD: turbines.
SUBSTANCE: system (100) for predicting turbine rub includes monitoring system (110) configured to form operational values (112) for a turbine based on information received from turbine, a correlation engine (114) configured to form at least one correlated value (115) from said values (112), that correlates a first operating value to a second operating value.
EFFECT: system also includes variable deriver (116) configured to form at least one derived variable (118) from a one of operating values and rub predictor (120), that forms rub prediction (122) based on at least one correlated value and at least one derived value.
