Abstract:
1. A method for mounting an annular internal fuel manifold relative to a combustor within a gas generator casing of a gas turbine engine, the method comprising: positioning the fuel manifold within a gas generator casing; applying a heat shield around a radially extending fuel inlet connected to the fuel manifold, the heat shield extending along a length of the fuel inlet disposed between the fuel manifold and the gas generator casing; and using the heat shield to at least partially support the fuel manifold within the gas generator casing by mounting the heat shield such that a proximal end thereof is in direct load bearing engagement with one or both of the fuel inlet and the gas generator casing and a distal end in direct load bearing engagement with the fuel manifold, such that the heat shield provides a load path therethrough which significantly reduces the load born by the fuel inlet, the heat shield thereby bear more load than the fuel inlet to support the fuel manifold.
