ABSTRACT OF THE DISCLOSURE The disclosure teaches a turbomachinery stator assembly which is concentric about an axis. The stator assembly includes a plurality of radially extending vanes positioned in circum- ferential array concentrically about the axis. Each vane has a circumferentially extending lug and an axially extending lug in axially spaced relationship thereto extending radially inward from the vane inner end. The vanes are supported in cantilever fashion over the vane radially outer ends. A diaphragm member extends radially inward from the vane inner ends and includes a plurality of radially opening slots spaced in circumferential array thereabout and dimensioned to matingly receive the vane axially extending lugs so as to concentrically position the diaphragm member from the vane inner ends. A ring member is positioned radially within the vane inner ends and includes a radially outwardly opening circumferential groove shaped to matingly engage the circumferential lugs at the inner end of each vane so as to concentrically support and axially position the ring member from the vane inner ends. The ring member is connected to the diaphragm so as to axially position the ring member with respect to the diaphragm.
