  • Methods and apparatuses for assembling a gas turbine engine
    Publication number: 20070119180
    Abstract: A method for assembling a gas turbine engine includes coupling an axisymmetric structure within the gas turbine engine, wherein the axisymmetric structure includes a plurality of mounting bushings extending from a radially outer surface of the axisymmetric structure, inserting a first quantity of fixed pins at least partially into a respective mounting bushing to facilitate securing the axisymmetric structure within the gas turbine engine, and inserting a second quantity of floating pins at least partially into a respective mounting bushing to facilitate each floating pin moving in both an axial and tangential direction with respect to a gas turbine engine centerline axis.
