Abstract of the Disclosure An annular ring for an axial flow gas turbine engine disposed inwardly of an array of stator vanes and between an annular flow path for hot working medium gases and an annular flow path for cooling air is dis- closed. The ring abuttingly engages the array of stator vanes in the radial direction to provide radial support and abuttingly engages the array of stator vanes and an outer air seal block the intermixing of gases from the working medium flow path and gases from the cooling air flow path. m e annular ring includes a first annular section and a second annular section. The first annular section has an axial width to radial height ratio greater than one and the second annular section has an axial width to radial height ratio less than one to adapt the ring for axial flexibility and radial stiff- ness and to enable the ring to accommodate growth and axial growth between the outer air seal and the array of stator vanes while remaining within the elastic limit.
