초록 ▼

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.

대표청구항 ▼

For a gas turbine engine having a combustor, a fuel-supply system for supplying fuel to the combustor and a plurality of fuel injectors for carrying fuel through a combustor outer casing to inject the fuel inside the combustor, an improved fuel-supply system comprising: a fuel manifold positionable around the combustor outer casing and including a primary fuel flowpath effective for providing fuel to said fuel injectors and a secondary fuel flowpath effective for collecting any leakage fuel that escapes said primary flowpath, wherein said fuel manifold is comprised of: a plurality of manifold segments and a plurality of fuel injector base sections, said manifold segments interconnecting said base sections of said fuel injectors, each of said manifold segments being effective for accommodating thermal expansion and contraction to reduce thermal strain and comprising an annular inner wall defining a first portion of said primary fuel flowpath and an annular outer wall spaced from and surrounding said inner wall for defining therebetween a first portion of said secondary fuel flowpath; each of said injector base sections having an inner passage defining a second portion of said primary fuel flowpath, said inner passage being in flow communication with said first annular inner wall of an adjoining manifold segment; and wherein each injector base section also has an outer passage defining a second portion of said secondary fuel flowpath, said outer passage being in flow communication with said annular outer wall of each adjoining manifold segment.
