Abstract: A seal assembly for a bearing compartment of a gas turbine engine includes a seal carrier, a seal element, a seal plate, and a trough. At least a portion of the seal element is within the seal carrier. The seal plate is in contact with the seal element and is configured to rotate relative to the seal element. The trough extends around the seal plate and comprises an annular channel positioned to capture oil slung from the seal plate.

Abstract: A towershaft support may comprise a mount support, and a mounting ring coupled to an aft portion of the mount support radially inward of the mount support, wherein the mounting ring and the mount support create a perimeter around a central void. The mounting ring may comprise a mounting flange on an outer diameter of the mounting ring and a fluid passageway on an inner diameter of the mounting ring fixedly coupled to the mounting flange, wherein the fluid passageway comprises an outer wall enclosing an internal passage configured to pass fluid therethrough.
