Abstract
A shroud segment for a gas turbine engine includes a hook having an undercut surface. Various construction details are developed that provide a segment having a hook with minimized bending stress. In a particular embodiment, a shroud segment includes a plurality of hooks spaced along the leading and trailing edges of the shroud segment. Each of the plurality of hooks includes a positioning surface, a support surface and an undercut surface therebetween. The positioning surface defines the limits of axial movement of the shroud segment. The support surface reacts the radial loading on the shroud segment during operation of the gas turbine engine. The undercut surface is offset from the stator assembly to define the maximum length of the support surface.
