Abstract
A core structure for a providing a cooling passage in a gas turbine engine includes a core body that has a first cooling passage core. The first cooling passage core has a first width in a chord-wise direction near a first wall. A second width in the chord-wise direction near a second wall. A third width in the chord-wise direction between the first and second walls. The third width being smaller than the first and second widths to form an hourglass shape.
Claims18
A core structure for a providing a cooling passage in a gas turbine engine component, comprising:
- a core body having a first, second, and third cooling passage core, the first cooling passage core having first width in a chord-wise direction near a first wall, a second width in the chord-wise direction near a second wall, and a third width in the chord-wise direction between the first and second walls, the third width being smaller than the first and second widths to form an hourglass shape, the first cooling passage core arranged between the second and third cooling passage cores, and the second and third cooling passage cores having a kite shape, wherein a perimeter of the second and third cooling passage cores include an opposed pair of acute angles and an opposed pair of obtuse angles.
