ABSTRACT:
A gas turbine engine is provided with an improved fuel system that features a fuel manifold with a primary and secondary fuel flowpath circumventing a combustor section of the engine. The manifold is formed with a double-walled construction for the purpose of withstanding high temperatures or fires around the combustor section and, additionally, to provide a secondary flowpath for draining any fuel leakage from the manifold. The two walls of the manifold include an inner wall that encloses the primary fuel flowpath through the fuel system. A concentric outer wall encloses the inner wall and protects the primary fuel flowpath. The double-walled system is made possible with a unique manifold assembly utilizing double-walled manifold segments that interconnect fuel flowpaths through fuel injector base sections. When assembled, these parts connect together to form an integral double-walled fuel manifold assembly.
