Gas turbine engine with angled and radial supports

In a gas turbine engine having structure defining an annular flow path including an inner annular wall and an outer annular wall, a casing for housing the structure, and a bearing compartment housing a rotor shaft bearing located radially inwardly from the inner annular wall, a support structure comprising:

• a plurality of circumferentially spaced radial support members extending radially inwardly from an outer mount connection at the casing to an inner mount connection at the bearing compartment housing, the radial support members providing structural support for radial bearing loads on the rotor shaft bearing;
• a plurality of circumferentially spaced axial support members extending radially and axially inwardly from an outer mount connection at the casing to an inner mount connection located on a diaphragm extending radially between connection locations at the bearing compartment housing and the inner annular wall, the axial support members comprising tie rods operating in tension to counteract a pressure force applied against the diaphragm.
