FIELD: mechanical engineering; turbines.
SUBSTANCE: proposed turbine compartment contains blades, shroud, sealing tabs on wheel shroud and on stator. Over-shroud guide member in form of solid of revolution with inner convex surface forming upper wall of channel is arranged on stator. Lower wall of channel is arranged on outer surface of shroud and is directed tangentially to limiting surface of stator at outlet.
EFFECT: increased economy of turbine compartment.
