Abstract:
1. A system for directing leakage air, flowing from a high static pressure side to a lower static pressure side of a stator vane assembly located in a compressor of a turbine engine, back into a primary working fluid flow path of the compressor to avoid interfering with the working fluid flow at a leading edge of the stator vane, said system comprising: a stator vane; a shroud member connected to the radially inner extreme of said stator vane; a stationary seal assembly connected to the radially inner extreme of said shroud member; at least one seal sealing a rotating surface located radially inward from said stationary seal assembly, wherein a leakage flow path is formed at the interface between said at least one seal and said stationary seal assembly; and at least one cover directing the leakage airflow into a primary working fluid path of the compressor to avoid interfering with the working fluid flow at the leading edge of the stator vane, the at least one cover further comprising:
