The opposing faces are disposed generally transversely with respect to the axis. A rotor assembly is mounted for rotation about the axis. The rotor assembly has a plurality of blades with tips of the blades being coupled to an annular band . At least a portion of the annular band is disposed in the gap . Seal structure extends from each opposing face of the shroud and into the gap to reduce swirl and minimize air leakage across the gap.
