Turbine vane cluster including enhanced vane cooling
First Claim
1. A vane cluster for a gas turbine engine comprising:
- an outer diameter platform;
an inner diameter platform;
a plurality of vanes spanning from the outer diameter platform to the inner diameter platform;
at least one inbound region defined between a first vane of said plurality of vanes and a second vane of said plurality of vanes, the first vane including a suction side facing the inbound region;
each of said vanes including a leading edge core passage and a trailing edge core passage; and
no less than six and no more than ten electrical discharge machined (EDM) holes disposed within at least 0.500 inches (12.7 mm) of a leading edge of the first vane, each of the EDM holes connecting a leading edge core passage of the vane to an exterior surface of the vane.

Abstract
A vane cluster for a gas turbine engine includes an outer diameter platform and an inner diameter platform. A plurality of vanes span from the outer diameter platform to the inner diameter platform. At least one inbound region is defined between a first vane of the plurality of vanes and a second vane of the plurality of vanes. The first vane includes a suction side facing the inbound region. Each of the vanes includes a leading edge core passage and a trailing edge core passage. A plurality of electrical discharge machined (EDM) holes are disposed within at least 0.500 inches (12.7 mm) of a leading edge of the first vane. Each of the EDM holes connect a leading edge core passage of the vane to an exterior surface of the vane.
