Abstract

A method of manufacturing an annular bearing housing (54) for a gas turbine engine includes: producing a flange outer structure segment (58); producing an intermediate structure segment (60) having an outer radial end (76), an inner radial end (78), a body (74) that extends between the outer radial end (76) and the inner radial end (78), and a branch member (84) that extends outwardly from the body (74); producing a main body segment (62); attaching the flange outer structure segment (58) to the outer radial end (76) of the intermediate structure segment (60); and attaching the main body segment (62) to the inner radial end (78) of the intermediate structure segment (60). At least one of the flange outer structure segment (54), the intermediate structure segment (60), or the main body segment (62) is produced using an additive manufacturing process.
