Augmentor spray bar mounting
First Claim
1. An augmentor spray bar seal comprising:
- a first portion comprising electrographitic carbon; and
a second portion comprising electrographitic carbon and engageable to the first portion in a backlocked interfitting in an assembled configuration wherein;
a periphery the seal is shaped essentially as a non-right non-circular cylinder; and
a planform of the seal is characterized by a straight first end, an at least partially rounded second end, and first and second straight sides.

Abstract
A gas turbine engine augmentor has a centerbody within a gas flowpath from upstream to downstream. The augmentor has upstream and downstream shell sections, a downstream rim of the upstream shell section meeting an upstream rim of the downstream shell section shell section. A plurality of vanes are positioned in the gas flowpath outboard of the centerbody. An augmentor spray bar fuel conduit extends through the centerbody and a first of the vanes to deliver fuel to the centerbody. A seal is mounted to the spray bar and positioned in a recess extending from at least one of the downstream rim of the upstream shell section and upstream rim of the downstream shell section shell section. The seal has a first portion and a second portion engaging the first portion in a backlocked interfitting.
