摘要:
A fabricated as turbine engine component and method of manufacturing. In one embodiment the component having a spar member (23) with a cover member (24) metalurgically bonded thereto. The bonding of the cover member (24) being controlled by an apparatus (27) that sequentially applies a substantially non-uniform bonding load across the components radius of curvature. The patterns utilized in the casting process are formed in one embodiment to a precision preformed geometry by a closed die forming operation.

A fuel spraybar assembly for spraying fuel within a gas turbine engine. The spraybar assembly includes radial and lateral members that distribute fuel within the flowpath. In one embodiment two lateral members are located at the radially inward end of a radial member and generally form a "T" shape. Circumferentially spaced adjacent spraybars subdivide the flowpath into a plurality of circumferential combustion zone segments. In one embodiment the junction of the radial and lateral members provides a flameholding feature that stabilizes the combustion flame. In another embodiment, fuel is introduced non-uniformly within the afterburner resulting in thermal vectoring of the engine thrust.

A thrust compensation apparatus (150) for high-speed rotating machinery includes an electromagnetic thrust bearing (20) having a thrust rotor (40) and a thrust stator (50), a first chamber (80) filled with a pressurized medium on one side of the bearing, and a second chamber (90) on the other side of the bearing. The pressure differential across the bearing augments the electromagnetic force between the rotor (40) and stator (50) in order to counteract the axial thrust load of the high-speed rotating machinery.

A cast metallic airfoil structure having a high stiffness core positioned therein for increasing the stiffness of the airfoil. In one embodiment, the high stiffness core is preferably formed of gamma titanium aluminde or a titanium metal matrix composite and is metallurgically bonded to the cast metallic airfoil structure. In one form the airfoil structure forms a portion of an integrally bladed rotor, and in a second form the airfoil structure has a dove tail attachment portion.

An actively cooled component (24) having a plurality of film cooling discharge apertures (50) passing through a heat transfer pedestal (55). In one embodiment the pedestal (55) is elongated so as to provide good covered turning for the cooling media exiting the cooled component. In one embodiment the discharge aperture has an L/D ratio in the range of about two to three.
