  • Thermally compensated synchronization ring of a variable stator vane assembly
    Patent number: 11002142
    Abstract: A variable vane assembly including a variable stator vane disposed in a main flow gaspath, the variable stator vane having a vane stem. The assembly also includes a case located at a radially outward location of the variable stator vane, the vane stem extending through a port of the case, the port defined by a port wall, a clearance defined by the vane stem and a port wall to allow gas from the main flow gaspath to pass therethrough. The assembly further includes a synchronization ring spaced from the case to define a gap. The assembly yet further includes a vane arm operatively coupled to a synchronization ring and to the vane stem, the vane arm redirecting gas from the main flow gaspath to the synchronization ring.
