Abstract
A stator assembly includes a first stator vane sub-assembly with a first platform and a first airfoil extending from the first platform, and a second stator vane sub-assembly with a second platform and a second airfoil extending from the second platform. A gap is defined circumferentially between the first stator vane sub-assembly and the second stator vane sub-assembly. The stator assembly also includes a shroud structure, a first chamber defined between the first platform and the shroud structure, a second chamber defined between the second platform and the shroud structure, and a damper spring seal structure. Also included is a plate having a first portion within the first chamber and a second portion within the second chamber, such that the plate extends from the first chamber across the gap to the second chamber.
