ABSTRACT:
A stator seal assembly for a gas turbine engine of a type having a high pressure compressor section and a high pressure turbine section, the stator seal having a seal segment extending between a stator vane support structure and disk seal teeth, the stator seal segment having an arm for forming a cavity, a retaining segment attached to the seal segment and the arm for sealing the cavity to form a dead air space, a control ring located in the cavity having a coefficient of thermal expansion lower than a coefficient of thermal expansion for the seal segment, and a honeycomb pad located between the arm and the seal teeth, whereby thermal expansion clearance between the stator vane and the rotor disk is minimized.
