Compressor discharge flowpath
First Claim
1. For a gas turbine engine having an axial centerline axis, a compressor for discharging compressed airflow, a combustor for receiving said compressed airflow and generating combustion gases, a turbine nozzle for receiving said combustion gases, and a casing surrounding said compressor, combustor, and nozzle, an annular compressor discharge flowpath for channeling said compressed airflow from said compressor to said combustor comprising:
- a flowpath outer wall;
a flowpath inner wall spaced from said outer wall;
a plurality of circumferentially spaced radially extending flowpath dividers extending between and fixedly joined to said outer and inner walls, each of said dividers having a longitudinal axis;
an annular inner support fixedly joined to said inner wall and extending axially for being joined to said turbine nozzle;
an outer support fixedly joined to said casing and extending axially for being joined to said outer wall, and comprising a plurality of circumferentially spaced beams each having a length along a longitudinal axis, said beams being sized and configured for carrying both axial force and torque transmitted therethrough from said nozzle to said casing while allowing said beams to bend radially for accommodating differential thermal movement between said casing and said outer wall; and
said beams being configured in symmetric paris, with each beam pair being disposed adjacent to and straddling a respective one of said dividers, with said longitudinal axes of said beam pair being equally spaced circumferentially oppositely to said longitudinal axis of said straddled divider.

Abstract
A compressor discharge flowpath for a gas turbine engine includes flowpath outer and inner walls joined to a plurality of circumferentially spaced flowpath dividers extending therebetween. An inner support extends from the inner wall and is joined to a turbine nozzle, and an outer support extends from the outer wall and is joined to an engine casing. The outer support preferably includes a plurality of circumferentially spaced beams being sized and configured for carrying both axial force and torque transmitted therethrough from the turbine nozzle to the casing while allowing the beams to bend radially for accommodating differential thermal movement between the casing and the outer wall.
