  • Stator having selectively applied thermal conductivity coating
    Patent number: 5127795
    Abstract: A gas turbine engine stator and method are disclosed which are effective for controlling non-axisymmetric radial running clearance between a stator flowpath surface and rotor blade tips. A coating of preselected thermal conductivity is predeterminedly disposed along the circumference of the stator to control circumferential thermally induced distortion and thereby control non-axisymmetric radial running clearance. In preferred embodiments of the invention, a high thermal conductivity coating may be applied to an annular flange for reducing temperature gradients therein. In another embodiment of the present invention, low thermal conductivity coatings may be applied to a stator to preferentially insulate the stator for reducing circumferential thermal distortion.
