Beschreibung
Zusammenfassung:	A vane cluster (100) for a gas turbine engine (20) includes an outer diameter platform (110) and an inner diameter platform (120). A plurality of vanes (130) span from the outer diameter platform (110) to the inner diameter platform (120). At least one inbound region (102) is defined between a first vane (130) of the plurality of vanes (130) and a second vane (130) of the plurality of vanes (130). The first vane (130) includes a suction side facing the inbound region (102). Each of the vanes (130) includes a leading edge core passage and a trailing edge core passage. A plurality of electrical discharge machined (EDM) holes (140) are disposed within at least 12.7mm of a leading edge (104) of the first vane (130). Each of the EDM holes (140) connect the leading edge core passage of the vane (130) to an exterior surface of the vane (130).
