Abstract

Official abstract text for this publication.

A gas turbine engine includes a core housing that includes an inlet case and an intermediate case that respectively provide an inlet case flow path and an intermediate case flowpath. A shaft provides a rotational axis. A hub is operatively supported by the shaft. A rotor is connected to the hub and supports a compressor section. The compressor section is arranged in a core flow path axially between the inlet case flow path and the intermediate case flow path. The core flowpath has an inner diameter and an outer diameter. At least a portion of inner diameter has an increasing slope angle relative to the rotational axis. A bearing is mounted to the hub and supports the shaft relative to one of the intermediate case and the inlet case.

First claim

Opening claim text (preview).

What is claimed is: 1. A gas turbine engine comprising: a core housing including an inlet case and an intermediate case that respectively provide an inlet case flow path and an intermediate case flowpath, wherein the inlet case includes a first inlet case portion defining the inlet case flow path, and a bearing support portion is removably secured to the inlet case portion; a fan arranged fluidly upstream of the core housing; a shaft providing a rotational axis; a geared arc…
