Abstract:

A lubrication system includes an inlet conduit having an inboard end attached to a bearing support and an outboard end for receiving lubricant. A lubricant inlet assembly is attached to the inlet conduit outboard end and has an inlet cap with a receptacle, an inlet cap body, and a cap base. The inlet receptacle is configured to mate with a lubricant supply line, where the inlet cap body has an outer cap enclosing an inner cap, the outer cap having a convoluted wall. An inlet conduit termination fitting has an outboard fitting section, with an o-ring in a circumferential groove, disposed inside the inlet cap, and an inboard fitting section attached to the inlet conduit outboard end. A cap heat shield encloses the inlet cap and a conduit heat shield is attached to the inlet conduit. The lubricant inlet assembly is mounted to an engine casing with a low-conductivity insulating gasket between the cap base and the engine casing.

Abstract:

An integral blisk assembly includes a ceramic blisk having a forward and aft axial facing surface. To allow for torque transfer from the blisk, a forward and aft attachment ring contact the forward and aft axial facing surfaces respectively. These rings are mounted to other rotating components in the engine and are made of metal. A metal shim or precious metal coating may be disposed between the contacting surfaces to further reduce any stresses at the point of contact. To provide radial piloting, metal pilot rings are disposed underneath the regions where the attachment rings and blisk make contact. The aft attachment ring also has an axially extending base portion that in the event of a blisk failure contacts a stop that extends inwardly from the forward attachment ring, thereby preventing the other components in the engine from shifting.
