Abstract

A gas turbine engine augmentor has a centerbody within a gas flowpath from upstream to downstream. A plurality of vanes are positioned in the gas flowpath outboard of the centerbody. An augmenter fuel conduit extends through a first of the vanes to deliver fuel to the centerbody. An electrographitic carbon bushing guides and supports the augmentor fuel conduit.

Claims (15)

1. A turbine engine augmentor comprising:

a centerbody within a gas flowpath from upstream to downstream;

a plurality of vanes positioned in the gas flowpath outboard of the centerbody;

an augmenter fuel conduit extending through a first of the vanes to deliver fuel to the centerbody; and

an electrographitic carbon bushing, the augmentor fuel conduit mounted to an engine static structure via the electrographitic carbon bushing, the electrographitic carbon bushing being in longitudinally sliding engagement with the augmentor fuel conduit so that the electrographitic carbon bushing guides the augmentor fuel conduit relative to the static structure.

2. The turbine engine augmentor of claim 1 wherein the augmentor fuel conduit delivers the fuel to a burner within the centerbody.

3. The turbine engine augmentor of claim 1 wherein the augmentor fuel conduit delivers the fuel to a spray bar manifold within the centerbody.

4. The turbine engine augmentor of claim 1 wherein the bushing is a split bushing.

5. The turbine engine augmentor of claim 1 wherein the bushing is a longitudinally split bushing.

6. The turbine engine augmentor of claim 1 wherein the bushing has first and second end flanges.

7. The turbine engine augmentor of claim 1 wherein:

the engine static structure is a turbine exhaust case (TEC); and

the bushing is supported between a pair of brackets to the turbine exhaust case.

8. The turbine engine augmentor of claim 1 wherein:

the electrographitic carbon bushing is in rotational sliding engagement with the augmentor fuel conduit.
