摘要： A torque pin includes a generally cylindrical body defining an external sidewall and having a longitudinal extending bore formed therein. The body also has a radially extending slot provided in the sidewall that intersects the bore. A cam is pivotally coupled to the body and is accommodated by the slot. The cam is moveable between an unlocking condition where the cam is fully accommodated by the slot and a locking condition where the cam is partially accommodated by the slot and extends outwardly beyond the sidewall. A retaining mechanism is disposed in the bore. The retaining mechanism acts on the cam when the cam is in the unlocking condition and moves into the slot when the cam is in the locking condition thereby to inhibit the cam from returning to the unlocking condition.

摘要： A seal assembly that seals a gap formed by a groove comprises a seal body, a biasing element, and a connection that connects the seal body to the biasing element to form the seal assembly. The seal assembly further comprises a concave-shaped center section and convex-shaped contact portions at each end of the seal body. The biasing element is formed from an elastic material and comprises a convex-shaped center section and concave-shaped biasing zones that are opposed to the convex-shaped contact portions. The biasing element is adapted to be compressed to change a width of the seal assembly from a first width to a second width that is smaller than the first width. In the compressed state, the seal assembly can be disposed in the groove. After release of the compressing force, the seal assembly expands. The contact portions will move toward a surface of the groove and the biasing zones will move into contact with another surface of the groove. The biasing zones will bias the contact portions of the seal body against the surface of the groove.

摘要： A method for manufacturing a rotor shaft includes fabricating a first shaft portion that extends axially from a first end to a second end, fabricating a second shaft portion that extends axially from a first end to a second end, and coupling the second shaft portion to the first shaft portion with an explosive bonded joint such that the second shaft portion is aligned substantially concentrically with respect to the first shaft portion, and such that the bonded joint extends obliquely with respect to a centerline axis of symmetry of the rotor shaft.

摘要： 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.
