Stator assembly including bleed ports for turbine engine compressor
First Claim
1. A stator assembly for a turbine engine, the stator assembly comprising:
- a stator support ring;
a plurality of stator vanes protruding radially inwardly from the stator support ring; and
at least one bleed port disposed on the stator support ring between at least two adjacent stator vanes of the plurality of stator vanes, wherein;
the at least one bleed port defines an oblong profile, the profile having a first end and a second end, the second end being substantially opposed from the first end along a length of the profile that extends from a leading edge of a first stator vane of the at least two adjacent stator vanes to a trailing edge of a second stator vane of the at least two adjacent stator vanes,the first end is closer to the first stator vane than to the second stator vane, and the second end is closer to the second stator vane than to the first stator vane, andthe profile is concave toward a suction sidewall of the second stator vane of the at least two adjacent stator vanes.

Abstract
A stator assembly for a turbine engine is disclosed. The stator assembly has a stator support ring, a plurality of stator vanes protruding radially inwardly from the stator support ring, and at least one bleed port disposed on the stator support ring between at least two adjacent stator vanes of the plurality of stator vanes. The at least one bleed port defines an oblong profile having a first end terminating near a leading edge of a first stator vane of the at least two adjacent stator vanes, and a second end, substantially opposed from the first end, terminating near a trailing edge of a second stator vane of the at least two adjacent stator vanes. The profile may be concave toward a suction sidewall of the second stator vane of the at least two adjacent stator vanes.
