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 o...
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 i...
