  • Inner shroud assembly for gas turbine engine variable vane system
    Patent number: 11549388
    Abstract: An inner shroud assembly of a variable vane actuation system for a gas turbine engine includes a shroud assembly comprising a multiple of forward shroud segments and a respective multiple of aft shroud segments. A multiple of variable vanes are rotationally retained at an inboard trunion between the forward and aft shroud segments of the shroud assembly. A retainer assembly includes a multiple of retainer ring segments that retain the forward and aft shroud segments together. The inner shroud assembly is assembled into an engine case with an inboard extending feature that engages with an outer diameter feature of each of the multiple of retainer ring segments.
