ABSTRACT:
Hot gas recirculation is eliminated between the trailing edge of a turbine shroud and the leading edge of a downstream vane by a tongue-and-groove interconnection between the two parts and a passage of cooling air through the interconnection to exhaust against the vane outer band and flow into the main gas stream. The shroud with its supporting structure is thereby maintained at substantially uniform temperatures around its circumference so as to present a round, close-tolerance relationship to its circumscribed turbine blade row.
