Abstract:
A method of operating a clearance control system for a gas turbine engine, includes estimating, in a control module, thermal expansion values of engine components based at least partially on an exhaust gas temperature of the gas turbine engine, determining an estimated clearance value based on the thermal expansion values and ducting airflow for cooling the engine components.
