Appl. No.:

10/815063

International Classification:

F01N007/10

US Classification:

060/323000

Abstract:

An exhaust manifold is provided having ceramic inner layer that is highly resistant to cracking from thermal cycling. In a preferred embodiment, the ceramic inner layer is slip cast from a slip composition having a major amount of fused silica which has an amorphous structure. The manifold also has a ceramic insulation layer, a strain isolation layer and an outer structural layer in various embodiments. According to one embodiment, the strain isolation layer is provided in the form of an intumescent mat that expands on heating and contracts on cooling up to a certain crossover temperature, above which it loses the ability to contract on cooling. In a preferred embodiment, a catalyst-coated support body is provided in the exhaust manifold. As exhaust gases pass through the manifold, noxious components of the exhaust gases begin to convert to environmentally benign species via the catalyst prior to reaching the catalytic converter. Methods of making an exhaust manifold also are provided.

International Classification:

US Classification:

416221

Abstract:

An improved blade retainer for locking radially projecting blades on a rotor includes an elastic spacer sized to be inserted into a radial space between the blade tang and the bottom of the rotor slot in a generally undeformed state without deformation of the tang or slot. The spacer is provided with a first arcuate surface which abuts the tang and a second arcuate surface which, in one embodiment, abuts the bottom of the rotor slot when the spacer is deformed, thereby exerting an outwardly directed load on the tang. The spacer is fixed against axial movement relative to the blades by means of a forward end lug which is in confronting and overlapping relationship with an end face on the blade tang when the spacer is deformed. Blocker means are insertable between the spacer and the bottom of the slot to retain the spacer in a deformed state and thereby bias the blade radially outwardly. A channelled sleeve can be provided under the spacer and blocker means to distribute the load over a greater area of the rotor slot to reduce wear thereof.

Abstract:

An improved blade mounting arrangement for a gas turbine engine with a turbine and an annular flowpath therethrough is disclosed. The improvement comprises a one-piece outer casing and a one-piece inner casing bounding the flowpath. The outer casing has a plurality of circumferential recesses disposed therein with each of the recesses having first and second axially opposite circumferential slots. A plurality of first turbine blades, each with axially facing tangs on a mounting platform, mate with the slots in the outer casing recess. The inner casing has a plurality of recesses disposed therein, each of the recesses including a forward circumferential slot and concentric aft radially outer and radially inner circumferential slots. A plurality of second turbine blades, each with forward and aft axially facing tangs on a mounting platform, mate with respective ones of forward slot and radially outer slot in the inner casing recess.
