Hole for rotating component cooling system

摘要

A rotor (31A) for a gas turbine engine (10) comprises an annular body (38) and a plurality of holes (40). The annular body (38) is configured to rotate in a circumferential direction (É) about an axis (CL) extending through a center of the annular body (38). The annular body (38) comprises an outer diameter surface (60B) and an inner diameter surface (60A). The plurality of holes (40) extends through the annular body (38). Each of the holes (40) comprises an elongate profile in the circumferential direction, and a side wall (58) extending between the outer diameter surface and the inner diameter surface. The side wall (58) is slanted in the circumferential direction (É).
