A seal assembly includes a plurality of seal segments for sealing between a rotor and a stator, wherein, when arranged together, the rotor, the stator, and the plurality of seal segments define a high pressure region and a low pressure region. The seal assembly further includes a biasing member engaged with the plurality of seal segments and at least one feature formed in the stator. As such pressurized fluid engaging with the at least one feature provides an aft-to-forward axial force that reduces friction between interfacing aft surfaces of the plurality of seal segments and the stator.

Seal assembly for a turbine engine

A turbine engine includes a rotor, a stator having an aft wall, and a seal assembly having a plurality of seal segments disposed between the rotor and the stator. The rotor, the stator, and the seal assembly are arranged together to define a high pressure region and a low pressure region. The turbine engine also includes at least one biasing member engaged with one or more of the plurality of seal segments. The plurality of seal segments include a primary seal segment and a secondary seal segment connected together via a flexible joint. As such, the flexible joint allows for angular misalignment between the primary seal segment and the secondary seal segment, thereby allowing the primary seal segment to move with the rotor while the secondary seal segment maintains contact with the aft wall of the stator.
