Abstract
A seal land includes a seal land body that extends circumferentially about an axis and radially between an inner seal land side and an outer seal land side. The seal land body is configured with a plurality of fluid passages arranged about the axis. A first of the fluid passages includes an inner passage segment and an outer passage segment fluidly coupled with the inner passage segment. The inner passage segment extends along a first trajectory within the seal land body towards the outer passage segment. The outer passage segment extends along a second trajectory within the seal land body away from the inner passage segment and towards the outer seal land side. The second trajectory is different than the first trajectory and includes a radial component and a circumferential component.
