  • Gas turbine engine case coated with thermal barrier coating to control axial airfoil clearance
    Patent number: 5645399
    Abstract: An engine case of a gas turbine engine is selectively coated with a thermal barrier coating to control axial clearance between rotating and stationary airfoils. The coating is applied to the thinner portions of the engine case to retard thermal expansion of these portions of the engine case during transient conditions of the gas turbine engine operation. The selectively coated engine case responds substantially uniformly to heating and thermal expansion during transient conditions, thereby reducing axial vane lean in gas turbine engines.
