Method of assembling a gas turbine engine and rotor assembly

摘要

A method facilitates assembling a gas turbine engine (10). The method comprises providing a rotor assembly (62) including a rotor shaft (26) and a rotor disk (66) that includes a radially outer rim (68), a radially inner hub (70), and an integral web (72) extending therebetween, wherein the rotor assembly is rotatable about an axis of rotation (28) extending through the rotor shaft, and coupling a disk retainer (82) including at least one discharge tube (164) to the rotor disk wherein the discharge tube extends outwardly from the disk retainer for pumping the air to a higher pressure before discharging cooling fluid therefrom in a direction that is substantially perpendicular with respect to the axis of rotation.
